Is there anyway to install the TI-Nspire CX CAS OS onto the TI Nspire CX non-CAS?
-
Officially, no.
Unofficially, no[t yet].
-
Progress? ??? ???
-
Nope I think but there was recently a discussion about this and why this is not going to be made very public (legal reasons): http://ourl.ca/14645/275121;topicseen#new
-
Progress?
-
From what I remember, in the news section of the site there was an update to OSLauncher that works most of the time, but I don't remember if it supports the CX yet. Of course we can't help directly on installing CAS on non-CAS, though, but hopefully such OSLauncher copy has instructions on how to actually get the application to work.
-

I don't see why this is any different from installing the CAS OS on a non-CX calculator.
-
What do you mean? Of course keep in mind that the post you just quoted was posted way back in Early 2012 and back then there were worries about TI taking legal actions against OSLauncher if abused or even more anti-Ndless stuff.
Because it is against Omnimaga rules to discuss/teach how to load a CAS OS on a non-CAS Nspire model, regardless of if it's a CX or not. Granted, a tutorial might quickly explain how to load a different OS than the intended one on your calculator without specifically stating CAS on non-CAS, and that way it will get away from the rules even if it's pretty much the exact same thing, but if it goes in details and specifically explains how to turn your TI-Nspire into a TI-Nspire CAS, it will fall under the cheating on math tests category per the rules.
I don't think the whole piracy/theft thing is considered an issue here anymore since it was clarified over time that the OSes are all offered for free on TI website and we can do whatever we want with the hardware, in the same way as we can convert a TI-73 into a TI-83 Plus or a FX-9750GII into a FX-9860GII.

nLauncher uses a flaw in boot2 1.4 which cannot be ran on the TI-Nspire CX.
-
So, can I be pointed into the direction of some tutorial or will you guys help me solve my delema? I bought the non CAS nspire CX for ACT and SAT and now that that's over with, I would like that OS on my non CAS calculator without spending another $140.

If you read my previous post (the one above your), you'll understand that you can't install nLaunch on a CX calculator.
Things can't be done in only one week, surely not so much.

Sitting at school, playing with my teacher's CX and CX CAS software when I notice it wants to update my OS and asks if I want to install from a file. Went and downloaded a file for CAS, tried to install on my non-CAS. Alert window declares that they don't match. Is it possible there is a way to maybe decrypt the install file and then alter it so that it (the file) says it can be installed on a non-CAS calculator? Or vice versa so that the software that installs the OS believes that the calculator is one equipped with CAS? Just a thought, I'm not a major programmer or anything. Just a high school student with some computer and software knowledge that really wants to get CAS on my nSpire. (I know the file is encrypted because I opened it in notepad, filled almost completely with seemingly random ASCII characters)
If anyone has any ideas, I'd love to get this working again. Sorry to revive a dead thread, but this is everything I'm currently worried about when it comes to the nSpire calculators.

It is possible as of yesterday, check it here: http://ourl.ca/18621 (http://ourl.ca/18621)

-
Holy necropost Batman ? :(
-
Also, that doesn't work on newer calcs. You should have precised on top of your tuto which calcs this works on.
-
Any ideas as to how "safe" this hack is? I ask because I had a TI-84+ CSE with a hex editor that, as a result of the hex editor crashing, prevented the calc from turning on again. :banghead:
-
Normally there shouldn't be any way to permanently brick a TI-84 Plus CSE unless the hex editor lets you edit Flash/Archive memory and you accidentally erase both parts of the OS and the certificate. Have you tried reinstalling the OS?
As for the CAS to non-CAS hack, since running ASM/C programs or alternate OSes is very hackish compared to other calc models, almost everything that uses Ndless software is dangerous, although normally, you should be safe as long as you don't misuse the program called Nover nor do something wrong with the serial dock connector at the bottom of the calc.
-
How many have actually hacked their CX as of now...?
-
We can't know exactly how many people have enjoyed native coding on their Nspire (CX), but I posted that a little while ago, here (http://ourl.ca/19357/357492) :
Oh and, on our (TI-Planet) part, Ndless 3.1, launched in late January 2012, reached 40k downloads a few days ago (or was it yesterday ?) and is the most downloaded file every week I believe (not counting exam stuff when it's exam time, though), and is the 1st overall (again not counting the exam stuff). Approx 71 times / day , 2100 / month.
If you're talking about specific nLaunch statistics, well, around 1000 times on TI-Planet least. (both classic and cx)
-
Add to that the many downloads on Ticalc.org (Ranked as 149 on our all-time top downloads list with 43617 downloads. Ranked as 32 on our top downloads list for the past seven days with 242 downloads.) and Omnimaga (ranked 4th with 3769 downloads).
Most people want to hack their Nspire CX because they either want the CAS OS on their non-CAS calc or they want Pokemans.
-
Ah ok. I should have specified hacking CAS onto a non-CAS CX Nspire.
Sorry for this noobish stuff, I am just worried about my Nspire bricking, for, as sad as this sounds, my Nspire is my baby :P
Also, I appreciate the tolerance and assistance, for I've had bad experience with other forums. Thanks! ;D
-
No problem. Omni tries to remain as friendly as possible to newcomers, those who are new to the calculator scene in particular (since we all gotta start somewhere and the Nspire is particularly challenging when it comes to hacking) :) , unless of course somebody begs for help on doing illegal stuff or cheating on tests lol. :P
-
Is there a thread for Doors CS for Nspire CX?
-
Nah. Actually I don't think such shell would ever be needed for the Nspire considering we already run documents like Lua or Basic ones. On the 83+ we have DCS because it makes it less confusing to run ASM programs.
-
Ok thanks. Well my Nspire has the unreleased OS so I guess I'll just have to hope somebody updates this hack for the new OS :/
-
Oh wait do you mean it's a prototype? ??? If so, then which OS do you have?
-
It's not a prototype, just some weird idea TI had to put an unreleased (at least on their website as of a month ago). the OS on mine is 3.2.4.1237.
-
Oh ok lol. Yeah I remember that OS 3.2.4.1237 wasn't out yet at first, which would have caused serious issues for people who accidentally delete the OS off their calc. >.<
-
NOOOOOO I BRICKED MY CX ;~;
-
In general, bricking a Nspire calculator is quite hard ;)
Since your calculator came with 3.2.4.1237 preinstalled, according to another post of yours, you cannot directly install any older version. Beyond that, what you can do with the calculator depends on the hardware revision:
* if the hardware revision is I or older, you could reflash the boot2, with extra, cheap equipment known as USB / RS232 TTL adapter, and then proceed to use, say, OS 3.1.0.392;
* if the hardware revision is J, K or higher, you're out of luck, at the time of this writing. Boot2 3.10.16 doesn't work on those calculators, it's no use reflashing it. The only thing you can do with these pieces of junk is transfer back the 3.2.4.1237 OS of reduced functionality.
-
Luckily for me, TI has OS 3.2.4 hidden on their website...

-
It's been linked from TI-Planet for weeks ;)
-
I really need to update the OS download topic on Omni at one point. Almost all links must be broken by now >.<

How many have actually hacked their CX as of now...?
Hello every one!
:ninja: Here, Here..\m/ The Non-CAS info could be updated or worded with better terminology and links, but I got mine to work. :angel:
I have pictures, but I guess I don't have the post count to upload them as of yet.
My Calc. professor has not allowed calculators since Calc I, and all work has to be handwritten anyway. He's a hard ass about it, but I'm used to it. Plus I like saying "I can do Calc, with out a calc!" :P
My reason was to see if I could do it, (The coder/hacker in me) and to double check my work. However, there are more ways to state an answer than you can shake stick at sometimes. (In other words, even the calculator is useless sometimes, unless you can figure out how HP came up with the answer, or especially on certain functions dealing with jump point discontinuities, and other graphical anomalies most calculators can't see or do) :crazy:
"I think I think; I think?"

If I may AndrewSanghera, it may be as simple as turning on the file type naming feature for windows. It is off by default. Otherwise you are just naming it phonenix.tns.tcc. Which is halfway in the right direction. Correct me if I am wrong or misunderstood your question.
Hope that helps you.
-
The Non-CAS info could be updated or worded with better terminology and links, but I got mine to work. :angel:
I think the info was made like this on purpose, in attempt to drive off the less smart people that only planned to use nLaunch to cheat in tests (for example, if CAS is banned) and do no effort in learning instead. However, I think the TI-Planet tutorial is more detailed.
-
Quick warning, DO NOT try this hack with a CX with 3.2.4.1237, for it bricks eternally and requires the calculator to be replaced altogether. :'( :banghead: :banghead: :banghead: :banghead: :banghead:

no it doesn't, just install 3.2.4 back to it (or 3.6 now it came out - non officially thought)

if you are using windows you need to desactivate an option
very simple

doing this you can see the extension of the file
phoenix.tns.tcc
and rename to
phoenix.tns
enter and now it is an .tns file

Is there anyway to install the TI-Nspire CX CAS OS onto the TI Nspire CX non-CAS? I'm from brasil and i have a texas nspire cx, but i need the cas on the calculator!
The version of my calculator os is TI_NspireCX_3.2.4.1237. Please help me! I tried this on the post but didn't work =/ .Sorry for my bad english.
Thanks!
-
You can't with 3.2.4 atm.
-
/me is seriously considering flaming the next reading disabled who asks this question
-
You can do that on other places, but not on Omnimaga ;)
-
Yeah, it's just annoying that they post here without even trying to read the thread. They come and ask without even trying to do research on their own. This is not how you do CS.
-
I have been seeing this more then ever, maybe if we post a news article people will listen?
Or, they will just go down to the comments and ask, should I post without reading the article?
-
Even if they read the news article they would still ask "Any (http://ourl.ca/12650/337195) progress (http://ourl.ca/12650/277429) ?"
-
I have to donwgrade the calculator to install? Is that possible?
-
Before judging if reading the thread was viable, I checked how long it was, but seeing that it's not several pages long, I agree that before asking questions, it would be best to read the topic.
Anyway, if your calculator hardware revision is A to I (see the last letter at the end of the serial number on the back), you can use a RS232/TTL interface on Ebay to downgrade, but if your letter is J or K, you're screwed.
-
You need to check 3 things :
- The manufacturing model (last letter of the timestamp). If > I, Throw it by the window.
- The boot2. If > 3.1.x you have to downgrade it using a TTL/RS232 adaptator and a telnet unit.
- The OS. If >= 3.2.4 you can still install nLaunch, but its prefered to downgrade anyway.
-
Wait, I thought you needed 3.1 as the installed OS to run nLaunch? O.O (like with Ndless)
-
I think there was a news article about it:
http://ourl.ca/19948 might be it
EDIT: I think it was something else, finding the link
-
Nlaunch depends on boot2 3.1, not OS. ;)
-
Oh ok, I don't follow Nspire stuff as much anymore due to what TI has been doing, so I always thought that to run OS 3.6 with nLaunch, you needed 3.1 installed first, then launch 3.6 using nLaunch from there.
-
@DJ_O: You can install Nlaunch on OS-less TI-Nspire.
The only thing you need is a working Boot2 3.1.
-
Ah that's cool to hear. :)
I wish that Ndless could use the same exploit, so that it could run on OS 3.6 as easily as nLaunch can, without needing OS 3.1 anywhere.
-
The third generation of Ndless (Ndless 3.1 targeting OS 3.1) and nLaunch / nLaunch CX / nLaunchy (targeting boot2 1.4 on Clickpad/Touchpad like DowngradeFix and boot2 3.10.16 on CX) exploit the same vulnerability, but Clickpad/Touchpad boot2 3.1.131 and OS 3.2.0.1212 to 3.6.0.546 are not vulnerable to that hole.

Update:
--------------------------------------------------------
Instructions for the CX to CXCAS Exploit (Quick version)
--------------------------------------------------------
READ ME!
This information assumes that the reader is at risk for exploiting a TI-Nspire CX touchpad only calculator, wherever CX is denoted. Also, this instructional slightly curtails the already NlaunchCX v2.0 instructions, and tries to combine all restarts and steps where ever possible making an efficient and speedy non-CAS CX to a CXCAS switch, with out intermediary steps. In other words, this report is a quicker method for getting the CX OS to the "CXCAS OS exploit point", if one will, and works the same, if not better. However, I make no guarantees that it can be recreated exactly as stated for others. Do further research if uncomfortable with this modified exploit method before proceeding.
Furthermore, bricking the CX calc. is possible, but unheard to me. If worse comes to worse, just reinstall the original OS at step #2 through the TI-Nspire PC Software, then do it again at reboot. (Then close this instructional, and walk away very quickly) ;) I make no guarantees that no damages, or damages, will, or will not occur to ones CX calc. ;P On top of this, I do not condone illegal uses for the instructions contain herein. "They're on their own, especially if clueless". However, if anyone has questions, if it can be made more efficient, grammatically, or technically better, it's for those to do what they will. Otherwise, if one is hesitant, do some research by reading all posts from where this exploit began rumored.
Last but not least, I'm in the process of coding a C++/VB program to make the below steps even simpler. If allowed to do so, a "No Brainer" Exploit.zip/.exe for the Non-CAS to CAS TI Nspire calculators maybe available in the future, if I can find the time. The source files will be included of course, for those who want to improve upon it.
With that in mind....
CX calculators with serials ending with P-xxxxA-I, has in my research will work based on other testimonies, including my own. Otherwise, this exploit, or possibly other methods like this, may or may not work; outside of downgrading the CX OS, if even that.:/ For the sake of simplicity, The below exploit is for CX serial# P-xxxxA-I and OS's before or on 3.2.3.1233.tcc OS, but not including 3.2.3.1233.tcc onward.
-------------
Instructions:
-------------
Please read through first, and follow the steps exactly for any exploit to be successful. (See below For original nlaunch exploit instructions if needed)

5. Download TI-NspireCXCAS-3.1.x.xxx.tcc from: http://ti-pla.net/a3718 (*Notice* this is the CXCAS OS and not the CX OS)
6. Focus the TNOC program and load the downloaded TI-NspireCXCAS-3.1.x.xxxx.tcc file.
a) The TNOC executable is found here, more or less. C:\x...\TNOC\TNOC_1.24\Windows\TNOC_en.exe
b) Check the Delete boot2 box, then one can optionally delete the samples files in the Example folder, and process. However, this does not delete the Example folder, just the samples in the Example folder.
c) After TNOC'ing the TI-NspireCXCAS-3.1.x.xxxx.tcc file, find, and rename the TI-NspireCXCAS-3.1.x.xxxx_xx.tcc to "phoenix.tns"
d) Select the handheld by finding the handheld icon in the LRH screen in the TI-Nspire PC Software.
e) Add folder named nlaunch under...Documents\nlaunch\ (Left bottom screen area, where -Documents/+examples+MyLib...etc. are)
f) Drag phoenix.tns, into \nlaunch.(Although, any directory under the Document root will work)
g) Drag #3. files from nlaunchCX\CX\ {nlaunch.tns, preloader.tns} into Document\nlaunch.
7. Put CX calc into Maintenance Options Mode by pressing and holding {doc+enter+EE}. (Tricky) ;D
a) *Note* The calculator can be off, or on for steps #1.- #7.
b) Then depress and release the reset button on CX calc. back.
c) Once reset shows the TI screen loading bars, then release {doc+enter+EE}.
d) When CX calc enters Maintenance Options, choose 2 to delete OS, choose 1 to proceed, deleting,,,and then press any key to restart.
8. After the CX restarts, Open TI-Nspire PC Software, if not already opened, with CX calc. connected.
a) When the CX calc. restarts, shows a caution (/!\) symbol, Install OS, and the progress bar is stuck at 60%....
b) Select the CX hand held again by finding the handheld icon in the LRH screen in the TI-Nspire PC Software.
c) Drag or copy the nlaunch.tco from the PC nlaunchCX\CX\ into CX calc. Documents\nlaunch\
d) The TI-Nspire PC software will give an error dialog, "Error Experienced a problem while communicating with the handheld. A retry may be successfull." but low and behold, it installs the nlaunch.tco anyway on the CX calc. ;)
e) It takes a few minuets for the nlaunch exploit to install the phoenix.tns file.
f) If steps #1.- #8. c). are done properly, the TNOC'ed phoenix.tns "CXCAS OS" file will install and reboot. Then ABC123, blink, then ABC1234 will appear briefly in the upper LH corner of the CX calc, at the restart of the nlaunch.tco\phoenix.tcc install.
g) If not, push the reset button on back of CX calc. again and repeat #8.
9. Once installed, go through all the CX "CXCAS" calc. setup prompts.
a) *Notice* one of the CX system start up prompt says a CXCAS OS was installed. This can be further investigated by checking 5. Settings, 4. Status, tab, and About on the CX calc. to see if indeed the CX is now a CXCAS. If not start over, give up, and reinstall the CX back to the original OS at #2. (Then slowly close this instructional, and walk away very slowly)
b) *Note* If those have made it this far, and have had success, congrats. One is not "Out of the woods yet", Do Not Upgrade the calculator with an OS unapproved by this exploit mentioned in, and, or before this post until it's safe to do so. Mainly 3.2.4.xxxx.tcc OS onward, but others on may render the CX calc. stuck with that OS. Which ultimately means the unit is hard coded with no hopes in downgrading to make this exploit work again, or again it might work. (Per other testimonials)
c) However, my CXCAS V3.2.0.1219 OS works, but not all CX/CXCAS OSs will nlaunch correctly exploit. So read up on what has worked, and ignore what has not been posted as exploitable.
----------------------
Cautions and Warnings:
----------------------
A) I guarantee nothing, and I hold myself harmless to any damages done to the CX calc. unit, and, or from other further legal measures taken against those, by TI, and, or by academic constituents if this device is used in a manner not authorized by such authorities that are within the power that govern herein and here out this construed instructional. ;P
B) These, and other CX to CXCAS exploits are meant for those who love math, coding, TI's, and their freedom in using their other God given talents. Those who are educated, do their work mostly by hand, and then want to double check their work. Others, want to upgrade the CX to a CXCAS OS for personal use, and, or for their careers after graduating. Others feel that they have been cheated by a capitalistic system, and demand a product that was promised flawless beforehand. Wherever others fit in, heed these warnings!
C) Most educational institutions will not allow a CAS driven graphing calculator, or any calculator for that matter unless specifically authorized to do so. Some professors, or teachers have even been alerted via memos on which exploited TI Nspire OS are out there. Which most TI Nspires are. Then those in power can easily check under 5. Settings, 4. Status, tab, and About on the CX calc..
D) However, no matter how, or what intentions were when these instruction were found, one may make think thyself clever, innovative, curious, and maybe even intelligent. However, it also shows a tendency to be reckless by taking shortcuts in life, or in ones education. In other words...please, do not try to use this exploit where prohibitive.

Below are are the edited supplemental original nlaunch v2.0 instructions for the CX calc., minus the Clickpad and Touchpad info.
Copyright (C) 2012-2013 nLaunch team Copyright, (C) 2013 nLaunch CX guy.
-------------------------------------------------------------------------------------------------------------------------
=======================
| nLaunch CX v2.0 |
=======================
PLEASE READ THE WHOLE README BEFORE DOING ANYTHING.
nLaunch is a set of programs and crafted OS updates suitable for:
* Nspire Clickpad and Touchpad calculators running boot2 1.4.1571 ("1.4");
* Nspire CX calculators running boot2 3.1.0.16 ("3.1").
It enables users to install and launch arbitrary OS updates located into the
user-accessible part of the filesystem - especially Linux :-) (see
http://github.com/tangrs/linux for more information )
As usual, use at your own risk :-P
Initial installation
====================
Needless to say, all steps are important ;-)
**** CX installation (see above for Clickpad and Touchpad) *****
----------------------------------------------------------------
0) backup your documents from your nspire on your computer
1) install the 3.1.0.16 boot2, usually known as "3.1".
If you have installed OS 3.1.0.392, 3.2.0.1212, 3.2.0.1219 or 3.2.3.1233 you
already have it. If you have installed any newer version, you probably will
not be able to easily install the 3.1.0.16 boot2.
Otherwise, install OS 3.1.0.392:
CX CAS: http://ti-pla.net/a3718
CX : http://ti-pla.net/a3717
2) get a compatible OS. See
http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
- NOTE: Not all TI-OSes are compatible with nLaunch.
OSes 3.1.0.392, 3.2.0.1212, 3.2.0.1219 and 3.2.3.1233 are.
For a full list of compatible OSes, check src/patch.c
3) use TNOC ( http://ti-pla.net/a1922 ) on the OS upgrade to remove the boot2
(you can remove the examples too)
4) rename the TNOC'ed OS to phoenix.tns
5) transfer phoenix.tns to your calculator in the folder /nlaunch/, being at
the root of the user-accessible part of the file-system
6) get to the CX folder
7) transfer nlaunch.tns and preloader.tns to your calculator in the folder
/nlaunch/, being at the root of the user-accessible part of the file-system
8) if you have installed it on OS 3.1.0.392, uninstall Ndless by launching
ndless_resources.tns
9) reboot (the reset button is the easiest way), go to the maintenance menu
( http://ti-pla.net/t5360 ), delete OS (option 2)
10)reboot, transfer nlaunch.tco/tcc to your calculator (an error will certainly
be shown on the computer, check if it is ok on your calculator)
- /!\ the initial exploit can fail. If the progress bar is stuck at 60% and
nothing is shown (you should briefly see "YZ") at the top left of the
screen, reset and send nlaunch.tco/tcc again.
- /!\ getting to the OS the first time can be fairly long (max 3 min); the
progression bar can be quite unstable. If the bar did not move at all
during 3 minutes, consider the boot as a failure
- NOTE: unplugging the USB cable "at the right time", i.e. after sending
the TNO/TNC and shortly after the bar has reached 60% again, may increase
the reliability of the installation procedure. Likewise, the second
generation of Ndless (1.7/2.0) worked better when USB was unplugged.
11)enjoy :-)
- /!\ when rebooting, the progress bar can sometimes be stuck a 60% with
nothing shown at the top left of the screen. Simply press "reset" until it
works.
NOTE: if it is working fine and you want nLaunch to be more stealthy when
booting, you can compile a quiet version ("DEBUG 1" in nlaunch.c).
Update of the target OS version
===============================
1) get a compatible OS. See
http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
2) Use TNOC ( http://ti-pla.net/a1922 ) on the OS upgrade to remove the boot2
3) rename the TNOC'ed OS to phoenix.tns
4) transfer phoenix.tns to your calculator in the folder /nlaunch/, being at
the root of the user-accessible part of the file-system
5) reboot
- /!\ first boot can be fairly long (max 3 min); the progression bar can be
quite unstable.
Update of nLaunch
=================
1) get to the CLASSIC or CX folder according to your calculator
2) transfer nlaunch.tns to your calculator in the folder /nlaunch/, being at
the root of the user-accessible part of the file-system.
3) reboot
Uninstallation
==============
1) get any compatible OS. See
http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
2) use TNOC ( http://ti-pla.net/a1922 ) on the OS upgrade to remove the boot2
3) reboot, go to the maintenance menu ( http://ti-pla.net/t5360 ), delete OS
4) reboot, transfer the OS to your calculator
Troubleshooting
===============
Signification of a few debug strings:
* 'U': the OS was not recognized and thus not patched
* 'F': if this is an OS made by TI, this means it was not loaded correctly in
memory.
CX: if the reset button doesn't work, use a screwdriver to open the battery
door and remove the battery before plugging it back in.
Using Ndless with nLaunch
=========================
* Ndless 1.7/2.0 should work out of the box.
* if you want to use Ndless 3.1 with nLaunch, just send the custom
ndless_resources.tns provided in this distribution to the /ndless folder,
then reboot. The Ndless 3.1 loader is embedded in nLaunch.
If you want to uninstall a Ndless 3.1 handled by nLaunch, just remove
ndless_resources.tns and reboot. Warning, this is _very_ different from
vanilla Ndless: vanila Ndless is removed through launching
ndless_resources.tns, but one mustn't remove ndless_resources.tns !

-
Don't use nLaunch CX. nLaunchy (https://github.com/Excale/nLaunchy) is an actively developed fork of nLaunch CX.
-
Yeah, nLaunchy has support for:
* "switcher": copying the OS file instead of renaming it, allowing for OS 3.2/3.1, 3.3/3.1 and 3.6/3.1 switching packs (see TI-Planet);
* more OS versions;
* automatic overclocking on newer OS versions, in order to partially undo the speed damage done by TI;
* etc.
It also prevents a stupid way to get rid of nLaunchy from working.
The only proper way to get a calculator ready for testing is to erase all memory contents through the maintenance menu and to reflash it right in the exam testing room. Anything less than that is a leaky half-measure, if less costly, and will crap up at some point. Needless to say, when reflashing calculators right in the exam testing room is implemented, an OS tailored to any exam testing's needs can be reflashed, and the need for CAS / non-CAS difference, PTT, and suchlike artificial limitations, is removed.
-
It would be cool that we fix up this tutorial and sticky it.
-
If this tutorial is added to the tutorials section and/or stickied, there should be a big red warning added at the start saying "Cheating in tests is bad. Don't do it. Maths will be useful to you later on, so try to learn them instead." or something like that. :P
-
Just for others, who might be interested in successful stories... I can confirm the solution provided by Tinker on September 6th is working :)
-
Glad to hear. :)
-
hello, i just want to thank you for this!! it really works! i turned my cx into a cas. I bought the cx model without knowing that i would need the CAS, so when the moment of using cas came, i started to looking for a way tu do this. i finally got it, thank you so much
-
Glad to hear. :D
-
Sorry to revive An old thread, but i just got the ti nspire cx without the cas. Its been a genuine pain to use it without the cas features that even my old casio non graphing calc had (not All) i mean simplifying square roots. Almost all calculators have thT and a 150 dollar one doesnt, that just shows how money thirsty companies these days are... Pretty sad. I got mine And i upgraded to 3.6 (it was 3.2 before not sure if it was the version that was downgrade locked ) im pretty sure the tutorial two posts above me will not work. If it doesn't is there a way to get the features of cas on there without Os changes? Thank you!
-
Once you installed OS 3.6, there is no way to go back to 3.1 unless your calc serial number ends with the letter I or lower and that you have an Arduino with USB/TTL RS232 interface. I think you also need Boot2 version 3.1.0.16 to use nLaunch (which lets you use a CAS OS on a non-CAS model)

When I go to drag phoenix.tns to the calc it says "wrong handheld type for the os being sent." Plus it is labelled as phoenix.tns.tcc. I seem to be doing everything as described in theascen's post. Any help is appreciated.

Basically, you have to change the whole name into "phoenix.tns", not just what's before the ".tcc" part. If your OS doesn't show extensions (an doesn't let you change them when renaming), you have to find the option that lets you change the extension (Google "rename extension Windows" for example if you are on Windows).
-
is there a way to do it to a TI Nspire that ends in a "P"??
-
Nope, sorry.
Also, could you post the 5 chars before P ?
(It's the factory plus the date)
BTW, is the back of the calc white ?
-
I have just purchased a Nspire cx non cas and would like to upgrade it to cas. I have gone through this forum and tried a few things but am running into a problem with the os version that I am running. I have 3.2.4.1237 and have not been successful with any of the techniques. Can someone tell me what I need to do to downgrade to an earlier version so that I can continue to install the cas software.
Thank you in advance for the help.

My apologies, i read through the front side of this thread and got the answer. To bad I didn't buy this a year or two ago.

Is there any news on installing on models j, k and higher?
Up to which final letter is the hack working?
Before working an an own idea I'am interested if these are nlaunch-able /ndless-able.
regards
Jorge
-
The final letter on which nLaunchy works is I.
However, OS 3.1 and 3.6 are Ndlessable, regardless of the hardware revision. (3.9 is not though)

As Legimet says above, you can't use nLaunch/nLaunchy on hardware J and higher, but you can use Ndless on OS 3.6 fine. I don't think using OS 3.1 is possible on that calculator, though.
The difference with Ndless for 3.6 and hardware J or higher is that everytime your calculator reboots you'll have to re-install Ndless again, which might not be that bad, but a little annoying.
-
TX Legimet and DJ Omnimaga!
Sry 4 b'ng annoying but are there known and easy hardware / hw+sw exploits to nlaunchy or ndless j,k and higher with OS 3.9(+)?
If not I consider nspire j+ with 3.9+ as no more interesting, what do you think?
Regards and again Thanks alot!
Jorge
-
There's currently no way to install Ndless on OS 3.9 running hardware J and higher, sorry. I think it might be possible to downgrade an OS 3.9 TI-Nspire that has hardware A through I, but it would require extra hardware like an Arduino or RS232/TTL interface.
There is usually a gap of between 6 and 18 months between an OS release and a compatible Ndless release for that OS, depending of how busy the developers are are how hard it is to find exploits to run Ndless or nLaunchy on it.
OS 3.9 is interesting for people who don't mind only running Lua programs and the Lua language on OS 3.2 and higher is much faster than on 3.1 and lower, but not being able to use the many powerful Ndless programs out there is annoying.

Update to my previous post: Earlier yesterday an OS 3.9 downgrade got released: http://tiplanet.org/forum/viewtopic.php?p=172099&sid=fb36298f23817f0a43d587b870cf0c4b#p172099
If you are currently running OS 3.9 and are willing to downgrade, then hopefully this can help you. Make sure to read the instructions included with the download.

Hi and welcome to the forums. :) Just two advices I would like to give to make your stay on the forums easier and more enjoyable:
-Be careful with tutorials posted by new members like the one quoted above. In the tutorial above, for example, big warnings about the risk of bricking your calculator might have been omitted and some steps might be missing. Sometimes it's better to follow the original website link or to double-check everywhere in case. Thankfully, in your case, things seems to work fine, though, so that's good.
-Also instead of double or triple-posting, it's best to use the EDIT/Modify button to make it easier to read topics. :)
-
I am having a difficult time bc I keep getting the PP1234F Error in the upper right and I have to delete the OS and once I move nlaunch.tco I get that error again :'(

Hello guys!
I'm new here, Im from Germany ^^
My NON-CAS Firmware is 3.2.3.1233
i can Upgrade it now to 3.9.0.463
But i truely miss the CAS Features! ....!...
Can is upgrade it easy to a CAS Firmware? is it possible?
The Steps on Reply #85... i think that should be easy to do for me!....
should i try it? or is there a better way outthere?
Thx
EDIT:
Ouuhhhh Yeaa!!!!! Now i got a CX CAS ;)))) Holy Cow! Thanx Guys!!
It was SO easy! unbelievable! damn easy as Hell!
Thank you Guys! Thank you Thank you Thank you!!
Yea =)

Glad it worked for you. :)
Welcome to the forums too. :)

I apologize for the repetitive nature of this question:
I do have a good habit of reading entire threads before posting a question, and i apologize again for reviving a dead thread, but I suspect that maybe things have changed since november of last year(a lot can happen two months)
I have a nspire cx, serial #****007509 P-0911D, from my homework, I have read that nothing past hardware I is able to have the CAS software installed on it, is this still the case? If it is possible, is there a link to the instructions? my calc currently has OS 3.6.0.550 with ndless.
again, I apologize for the reviving of a dead thread, for the repetitive nature of this question and for any noobish mistakes(such as confused terminology)
Thank you!
-
Hi soo my calculator is Ti-snpire cx and it is has white on the sides, on the back it has P-1213L, this means that i cant make my calculator into a Cas?
Thank you in Advance!
-
I have tried to convert my Nspire CX into an Nspire CX CAS, and for the most part it has worked.
The issue I am currently having is that it randomly shuts off and reboots itself for no apparent reason. I had downloaded the CX 3.1.0.392 OS, but I forgot to install it before proceeding in the steps :( Does anyone know how I can go back and redo this safely?

Hi, thanks for the post. I am from El Salvador. And i bought (coming soon in a few days) a TI-NSpire with touchpad (Non CAS). It was a mistake, because i need a lot of things of CAS in the university, right now. Well, I want install CAS in my TI-NSpire, but... is it posible to do? I really need it.
-
Hi soo my calculator is Ti-snpire cx and it is has white on the sides, on the back it has P-1213L, this means that i cant make my calculator into a Cas?
Thank you in Advance!
Yes. I believe so. The post explain that.

L > J, so by trying to flash boot2 3.1 you'd effectively make your calc as useful as a brick.

Hello.
I need some personalized assistance. This is my first new TI Calculator since TI-85, so I'm playing catch up, so to speak. I have a TI-nspire CX (Non-CAS). The Navy Exchange here in Italy doesn't sell the CAS version and I didn't want to wait a month for a CAS version to be mailed from the US. How do I go about upgrading to CAS? My calculator specifics are below. Thank you in advance for your time and assistance.

Hi guys!!
this forum is amazing, congrats!
Please folks, could somebody upload a video on youtube to teach us step by step how to do this "upgrade" please!
Also, you could provide us more details of which calculators are able to do it, you just said that the those ones that ends with the letter - I - can be, what about the others, and others models?? I saw many people searching and asking for it, so please tell us more details. My one ends with C, have no idea of the meaning of that....
Please, upload a video for us, to make everybody happy without spending money in a new calculator! we're all broken students...
Cheers!

Update:
--------------------------------------------------------
Instructions for the CX to CXCAS Exploit (Quick version)
--------------------------------------------------------
READ ME!
This information assumes that the reader is at risk for exploiting a TI-Nspire CX touchpad only calculator, wherever CX is denoted. Also, this instructional slightly curtails the already NlaunchCX v2.0 instructions, and tries to combine all restarts and steps where ever possible making an efficient and speedy non-CAS CX to a CXCAS switch, with out intermediary steps. In other words, this report is a quicker method for getting the CX OS to the "CXCAS OS exploit point", if one will, and works the same, if not better. However, I make no guarantees that it can be recreated exactly as stated for others. Do further research if uncomfortable with this modified exploit method before proceeding.
Furthermore, bricking the CX calc. is possible, but unheard to me. If worse comes to worse, just reinstall the original OS at step #2 through the TI-Nspire PC Software, then do it again at reboot. (Then close this instructional, and walk away very quickly) ;) I make no guarantees that no damages, or damages, will, or will not occur to ones CX calc. ;P On top of this, I do not condone illegal uses for the instructions contain herein. "They're on their own, especially if clueless". However, if anyone has questions, if it can be made more efficient, grammatically, or technically better, it's for those to do what they will. Otherwise, if one is hesitant, do some research by reading all posts from where this exploit began rumored.
Last but not least, I'm in the process of coding a C++/VB program to make the below steps even simpler. If allowed to do so, a "No Brainer" Exploit.zip/.exe for the Non-CAS to CAS TI Nspire calculators maybe available in the future, if I can find the time. The source files will be included of course, for those who want to improve upon it.
With that in mind....
CX calculators with serials ending with P-xxxxA-I, has in my research will work based on other testimonies, including my own. Otherwise, this exploit, or possibly other methods like this, may or may not work; outside of downgrading the CX OS, if even that.:/ For the sake of simplicity, The below exploit is for CX serial# P-xxxxA-I and OS's before or on 3.2.3.1233.tcc OS, but not including 3.2.3.1233.tcc onward.
-------------
Instructions:
-------------
Please read through first, and follow the steps exactly for any exploit to be successful. (See below For original nlaunch exploit instructions if needed)
1. Download TI-Nspire PC Software 3.2.0.124 from TI website, install, and run.
a) Connect both CX calc and PC with the USB cable, if it's not already, and backup all data on CX calc.
b) Find, and connect to the CX calc. handheld through the TI-Nspire PC software by clicking on the lower right icon, where "Select
A Handheld" is found.
2. Download TI-NspireCX versions, 3.1.0.392, 3.2.0.1212, 3.2.0.1219 or 3.2.3.1233.tcc from: http://ti-pla.net/a3717
a) *NOTE* the unit may already have one of these CX OSs already pre-installed.
b) Check under 5. Settings, 4. Status, tab, and About on the CX calc.first if in doubt.
c) If so proceed to step #3 and ignore http://ti-pla.net/a3717.
d) If not, download a suitable OS from: http://ti-pla.net/a3717, and use the TI-Nspire PC Software to install before proceeding further.
3. Download, extract/unzip, nlaunchy CX 2.3 from: https://github.com/Excale/nLaunchy
4. Download, install, and run TNOC from: http://ti-pla.net/a1922
5. Download TI-NspireCXCAS-3.1.x.xxx.tcc from: http://ti-pla.net/a3718 (*Notice* this is the CXCAS OS and not the CX OS)
6. Focus the TNOC program and load the downloaded TI-NspireCXCAS-3.1.x.xxxx.tcc file.
a) The TNOC executable is found here, more or less. C:\x...\TNOC\TNOC_1.24\Windows\TNOC_en.exe
b) Check the Delete boot2 box, then one can optionally delete the samples files in the Example folder, and process. However, this does not delete the Example folder, just the samples in the Example folder.
c) After TNOC'ing the TI-NspireCXCAS-3.1.x.xxxx.tcc file, find, and rename the TI-NspireCXCAS-3.1.x.xxxx_xx.tcc to "phoenix.tns"
d) Select the handheld by finding the handheld icon in the LRH screen in the TI-Nspire PC Software.
e) Add folder named nlaunch under...Documents\nlaunch\ (Left bottom screen area, where -Documents/+examples+MyLib...etc. are)
f) Drag phoenix.tns, into \nlaunch.(Although, any directory under the Document root will work)
g) Drag #3. files from nlaunchCX\CX\ {nlaunch.tns, preloader.tns} into Document\nlaunch.
7. Put CX calc into Maintenance Options Mode by pressing and holding {doc+enter+EE}. (Tricky) ;D
a) *Note* The calculator can be off, or on for steps #1.- #7.
b) Then depress and release the reset button on CX calc. back.
c) Once reset shows the TI screen loading bars, then release {doc+enter+EE}.
d) When CX calc enters Maintenance Options, choose 2 to delete OS, choose 1 to proceed, deleting,,,and then press any key to restart.
8. After the CX restarts, Open TI-Nspire PC Software, if not already opened, with CX calc. connected.
a) When the CX calc. restarts, shows a caution (/!\) symbol, Install OS, and the progress bar is stuck at 60%....
b) Select the CX hand held again by finding the handheld icon in the LRH screen in the TI-Nspire PC Software.
c) Drag or copy the nlaunch.tco from the PC nlaunchCX\CX\ into CX calc. Documents\nlaunch\
d) The TI-Nspire PC software will give an error dialog, "Error Experienced a problem while communicating with the handheld. A retry may be successfull." but low and behold, it installs the nlaunch.tco anyway on the CX calc. ;)
e) It takes a few minuets for the nlaunch exploit to install the phoenix.tns file.
f) If steps #1.- #8. c). are done properly, the TNOC'ed phoenix.tns "CXCAS OS" file will install and reboot. Then ABC123, blink, then ABC1234 will appear briefly in the upper LH corner of the CX calc, at the restart of the nlaunch.tco\phoenix.tcc install.
g) If not, push the reset button on back of CX calc. again and repeat #8.
9. Once installed, go through all the CX "CXCAS" calc. setup prompts.
a) *Notice* one of the CX system start up prompt says a CXCAS OS was installed. This can be further investigated by checking 5. Settings, 4. Status, tab, and About on the CX calc. to see if indeed the CX is now a CXCAS. If not start over, give up, and reinstall the CX back to the original OS at #2. (Then slowly close this instructional, and walk away very slowly)
b) *Note* If those have made it this far, and have had success, congrats. One is not "Out of the woods yet", Do Not Upgrade the calculator with an OS unapproved by this exploit mentioned in, and, or before this post until it's safe to do so. Mainly 3.2.4.xxxx.tcc OS onward, but others on may render the CX calc. stuck with that OS. Which ultimately means the unit is hard coded with no hopes in downgrading to make this exploit work again, or again it might work. (Per other testimonials)
c) However, my CXCAS V3.2.0.1219 OS works, but not all CX/CXCAS OSs will nlaunch correctly exploit. So read up on what has worked, and ignore what has not been posted as exploitable.
----------------------
Cautions and Warnings:
----------------------
A) I guarantee nothing, and I hold myself harmless to any damages done to the CX calc. unit, and, or from other further legal measures taken against those, by TI, and, or by academic constituents if this device is used in a manner not authorized by such authorities that are within the power that govern herein and here out this construed instructional. ;P
B) These, and other CX to CXCAS exploits are meant for those who love math, coding, TI's, and their freedom in using their other God given talents. Those who are educated, do their work mostly by hand, and then want to double check their work. Others, want to upgrade the CX to a CXCAS OS for personal use, and, or for their careers after graduating. Others feel that they have been cheated by a capitalistic system, and demand a product that was promised flawless beforehand. Wherever others fit in, heed these warnings!
C) Most educational institutions will not allow a CAS driven graphing calculator, or any calculator for that matter unless specifically authorized to do so. Some professors, or teachers have even been alerted via memos on which exploited TI Nspire OS are out there. Which most TI Nspires are. Then those in power can easily check under 5. Settings, 4. Status, tab, and About on the CX calc..
D) However, no matter how, or what intentions were when these instruction were found, one may make think thyself clever, innovative, curious, and maybe even intelligent. However, it also shows a tendency to be reckless by taking shortcuts in life, or in ones education. In other words...please, do not try to use this exploit where prohibitive.

Below are are the edited supplemental original nlaunch v2.0 instructions for the CX calc., minus the Clickpad and Touchpad info.
Copyright (C) 2012-2013 nLaunch team Copyright, (C) 2013 nLaunch CX guy.
-------------------------------------------------------------------------------------------------------------------------
=======================
| nLaunch CX v2.0 |
=======================
PLEASE READ THE WHOLE README BEFORE DOING ANYTHING.
nLaunch is a set of programs and crafted OS updates suitable for:
* Nspire Clickpad and Touchpad calculators running boot2 1.4.1571 ("1.4");
* Nspire CX calculators running boot2 3.1.0.16 ("3.1").
It enables users to install and launch arbitrary OS updates located into the
user-accessible part of the filesystem - especially Linux :-) (see
http://github.com/tangrs/linux for more information )
As usual, use at your own risk :-P
Initial installation
====================
Needless to say, all steps are important ;-)
**** CX installation (see above for Clickpad and Touchpad) *****
----------------------------------------------------------------
0) backup your documents from your nspire on your computer
1) install the 3.1.0.16 boot2, usually known as "3.1".
If you have installed OS 3.1.0.392, 3.2.0.1212, 3.2.0.1219 or 3.2.3.1233 you
already have it. If you have installed any newer version, you probably will
not be able to easily install the 3.1.0.16 boot2.
Otherwise, install OS 3.1.0.392:
CX CAS: http://ti-pla.net/a3718
CX : http://ti-pla.net/a3717
2) get a compatible OS. See
http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
- NOTE: Not all TI-OSes are compatible with nLaunch.
OSes 3.1.0.392, 3.2.0.1212, 3.2.0.1219 and 3.2.3.1233 are.
For a full list of compatible OSes, check src/patch.c
3) use TNOC ( http://ti-pla.net/a1922 ) on the OS upgrade to remove the boot2
(you can remove the examples too)
4) rename the TNOC'ed OS to phoenix.tns
5) transfer phoenix.tns to your calculator in the folder /nlaunch/, being at
the root of the user-accessible part of the file-system
6) get to the CX folder
7) transfer nlaunch.tns and preloader.tns to your calculator in the folder
/nlaunch/, being at the root of the user-accessible part of the file-system
8) if you have installed it on OS 3.1.0.392, uninstall Ndless by launching
ndless_resources.tns
9) reboot (the reset button is the easiest way), go to the maintenance menu
( http://ti-pla.net/t5360 ), delete OS (option 2)
10)reboot, transfer nlaunch.tco/tcc to your calculator (an error will certainly
be shown on the computer, check if it is ok on your calculator)
- /!\ the initial exploit can fail. If the progress bar is stuck at 60% and
nothing is shown (you should briefly see "YZ") at the top left of the
screen, reset and send nlaunch.tco/tcc again.
- /!\ getting to the OS the first time can be fairly long (max 3 min); the
progression bar can be quite unstable. If the bar did not move at all
during 3 minutes, consider the boot as a failure
- NOTE: unplugging the USB cable "at the right time", i.e. after sending
the TNO/TNC and shortly after the bar has reached 60% again, may increase
the reliability of the installation procedure. Likewise, the second
generation of Ndless (1.7/2.0) worked better when USB was unplugged.
11)enjoy :-)
- /!\ when rebooting, the progress bar can sometimes be stuck a 60% with
nothing shown at the top left of the screen. Simply press "reset" until it
works.
NOTE: if it is working fine and you want nLaunch to be more stealthy when
booting, you can compile a quiet version ("DEBUG 1" in nlaunch.c).
Update of the target OS version
===============================
1) get a compatible OS. See
http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
2) Use TNOC ( http://ti-pla.net/a1922 ) on the OS upgrade to remove the boot2
3) rename the TNOC'ed OS to phoenix.tns
4) transfer phoenix.tns to your calculator in the folder /nlaunch/, being at
the root of the user-accessible part of the file-system
5) reboot
- /!\ first boot can be fairly long (max 3 min); the progression bar can be
quite unstable.
Update of nLaunch
=================
1) get to the CLASSIC or CX folder according to your calculator
2) transfer nlaunch.tns to your calculator in the folder /nlaunch/, being at
the root of the user-accessible part of the file-system.
3) reboot
Uninstallation
==============
1) get any compatible OS. See
http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
2) use TNOC ( http://ti-pla.net/a1922 ) on the OS upgrade to remove the boot2
3) reboot, go to the maintenance menu ( http://ti-pla.net/t5360 ), delete OS
4) reboot, transfer the OS to your calculator
Troubleshooting
===============
Signification of a few debug strings:
* 'U': the OS was not recognized and thus not patched
* 'F': if this is an OS made by TI, this means it was not loaded correctly in
memory.
CX: if the reset button doesn't work, use a screwdriver to open the battery
door and remove the battery before plugging it back in.
Using Ndless with nLaunch
=========================
* Ndless 1.7/2.0 should work out of the box.
* if you want to use Ndless 3.1 with nLaunch, just send the custom
ndless_resources.tns provided in this distribution to the /ndless folder,
then reboot. The Ndless 3.1 loader is embedded in nLaunch.
If you want to uninstall a Ndless 3.1 handled by nLaunch, just remove
ndless_resources.tns and reboot. Warning, this is _very_ different from
vanilla Ndless: vanila Ndless is removed through launching
ndless_resources.tns, but one mustn't remove ndless_resources.tns !

This process worked beautifully! Once I found out how to change file types in Windows, I was in the clear! :thumbsup: :thumbsup: :thumbsup: :thumbsup:

Referring to Post #106, I am getting stuck at Step 8. After copying nlaunch.tco, the "Operating System not found. Install OS now." message keeps coming up no matter how many times I try it. Below is my setup:
P-####D
TI-Nspire PC Software 3.2.0.124
TI-NspireCX 3.1.0.392
nlaunchy CX 2.3
TNOC 1.24
TI-NspireCXCAS-3.1.0.392.tcc
Any help would be greatly appreciated.
Update.
So, now I'm just messing around and trying different things. I pasted phoenix.tns, nlaunch.tns, and then nlaunch.tco into the CX calc and it rebooted with the same "Experienced a problem while communicating with the handheld. A retry may be successful."
Here are the differences now. There was no error on the CX calc this time, but in the upper left hand corner PP123 displayed. After a few moments it went to PP1234567 and the bar progressed to about 99% as opposed to about 60%.
Update 2

If you have C as the last letter, you could install CAS.
So many questions, so little answers. PLEASE READ THAT END LETTERS A-I COULD RUN CAS. ANYTHING J AND PAST CANNOT. It seems like multiple people ask if it works or not when this guide pretty clearly tells them if it does not. Maybe it is that people do not speak or read english well, but I do think there is some confusion in the installation instructions. My first install took possibly one hour, and maybe more with some troubleshooting. Anyway I have to leave, so hope you guys could answer any of the previous questions without my help.
Hi guys!!

D model could handle CAS.
I apologize for the repetitive nature of this question:
I do have a good habit of reading entire threads before posting a question, and i apologize again for reviving a dead thread, but I suspect that maybe things have changed since november of last year(a lot can happen two months)
I have a nspire cx, serial #****007509 P-0911D, from my homework, I have read that nothing past hardware I is able to have the CAS software installed on it, is this still the case? If it is possible, is there a link to the instructions? my calc currently has OS 3.6.0.550 with ndless.
again, I apologize for the reviving of a dead thread, for the repetitive nature of this question and for any noobish mistakes(such as confused terminology)
Thank you!

Yes. I believe so. The post explain that.
As i understand, non cx Nspire have similar codes to CX, so check the model.
The conversion is possible:

Hi there!
I've been researching around this topic for a while, starting off with OS 3.9 and downgrading to 3.6 to try ndless etc. I've come across a number of different guides to downgrading and installing the CX CAS OS on the normal CX calculator, but each one is different and with the whole language translation things get confusing:P. So I was just wondering whether you could outline what I could to to install the CAS OS - if it is possible. I have the TI-nspire CX OS version 3.6.0.550, Boot1 version 3.0.0.99, Boot2 version 3.2.4.7 and serial number P-0511C. Also, I currently have ndless version 3.6 installed, in case that is useful! I understand that I may need to get an adapter to flash the Boot2, but I also don't know whether there are newer ways to installing the CAS OS. If someone could get back to me that would be great! ;D ;D ;D
Thanks,
Harry

Hello, first post here!
I managed to CAS my CX a while back and I'm currently on OS 3.1.0.392
Could someone please tell me how to update the OS to 3.2.3.1233 (Am I correct in thinking that is the highest I can go?)
I am obviously assuming it isn't as easy as a normal update?
-
here are some files if they work. dont know if u could download. i have phoenix.tns and i will verify it works so you could skip most of the steps.
https://drive.google.com/folderview?id=0B8SdWA1apqARfnAzN0lIX21wa2Q2QVpUSEM3d0VMdlBFS0Rib1VFZGs1N2UwMTI0RDZ0RUk&usp=sharing
Dont know how google sharing works. maybe it does, maybe it doesnt.

I was wondering if 3.1.0.392, 3.2.0.1212, 3.2.0.1219 or 3.2.3.1233.tcc are the only os that could be switched. I have os 3.2.2.1231 and was thinking of skipping the update, but i dont want to waste 2 hrs fixing it.
Also, it seems like texas instruments has updated their computer/calc communication software where you cant install outdated software. so looks like you need to go to http://tiplanet.org/forum/archives_voir.php?id=9676 to search for an older version of TI-CONNECT. i have not verified this though, but installed it on a friends computer and could not drag and drop an old os.
Hi there!
I've been researching around this topic for a while, starting off with OS 3.9 and downgrading to 3.6 to try ndless etc. I've come across a number of different guides to downgrading and installing the CX CAS OS on the normal CX calculator, but each one is different and with the whole language translation things get confusing:P. So I was just wondering whether you could outline what I could to to install the CAS OS - if it is possible. I have the TI-nspire CX OS version 3.6.0.550, Boot1 version 3.0.0.99, Boot2 version 3.2.4.7 and serial number P-0511C. Also, I currently have ndless version 3.6 installed, in case that is useful! I understand that I may need to get an adapter to flash the Boot2, but I also don't know whether there are newer ways to installing the CAS OS. If someone could get back to me that would be great! ;D ;D ;D
Thanks,
Harry
you need to get the 3.6 to 3.2 switchpack, from what i understand, in order to install cas version 1.0. CAS could be installed only on os 3.1.0.392, 3.2.0.1212, 3.2.0.1219 or 3.2.3.1233.tcc. Takes a while to figure out what to do, but there is a post on downgrading OS.
Hello, first post here!
I managed to CAS my CX a while back and I'm currently on OS 3.1.0.392
Could someone please tell me how to update the OS to 3.2.3.1233 (Am I correct in thinking that is the highest I can go?)
I am obviously assuming it isn't as easy as a normal update?
You could try drag and dropping 3.2.3.1233 from http://tiplanet.org/forum/archives_voir.php?id=9676 into the calculator window on TI-CONNECT software. If it doesnt work, it means you need an older version of TI CONNECT to put the outdated os 3.2.3.1233 on. then follow the steps on page five of this board thread.

Also looks like im the only one to help people here. If installation works for you, please come back and help others. Dont know how many people use this forum.

Update:
--------------------------------------------------------
Instructions for the CX to CXCAS Exploit (Quick version)
--------------------------------------------------------
READ ME!
This information assumes that the reader is at risk for exploiting a TI-Nspire CX touchpad only calculator, wherever CX is denoted. Also, this instructional slightly curtails the already NlaunchCX v2.0 instructions, and tries to combine all restarts and steps where ever possible making an efficient and speedy non-CAS CX to a CXCAS switch, with out intermediary steps. In other words, this report is a quicker method for getting the CX OS to the "CXCAS OS exploit point", if one will, and works the same, if not better. However, I make no guarantees that it can be recreated exactly as stated for others. Do further research if uncomfortable with this modified exploit method before proceeding.
Furthermore, bricking the CX calc. is possible, but unheard to me. If worse comes to worse, just reinstall the original OS at step #2 through the TI-Nspire PC Software, then do it again at reboot. (Then close this instructional, and walk away very quickly) ;) I make no guarantees that no damages, or damages, will, or will not occur to ones CX calc. ;P On top of this, I do not condone illegal uses for the instructions contain herein. "They're on their own, especially if clueless". However, if anyone has questions, if it can be made more efficient, grammatically, or technically better, it's for those to do what they will. Otherwise, if one is hesitant, do some research by reading all posts from where this exploit began rumored.
Last but not least, I'm in the process of coding a C++/VB program to make the below steps even simpler. If allowed to do so, a "No Brainer" Exploit.zip/.exe for the Non-CAS to CAS TI Nspire calculators maybe available in the future, if I can find the time. The source files will be included of course, for those who want to improve upon it.
With that in mind....
CX calculators with serials ending with P-xxxxA-I, has in my research will work based on other testimonies, including my own. Otherwise, this exploit, or possibly other methods like this, may or may not work; outside of downgrading the CX OS, if even that.:/ For the sake of simplicity, The below exploit is for CX serial# P-xxxxA-I and OS's before or on 3.2.3.1233.tcc OS, but not including 3.2.3.1233.tcc onward.
----------------------
Cautions and Warnings:
----------------------
See previous posts
I have bolded some steps to hopefully make it easier.
-------------
Instructions:
-------------
Please read through first, and follow the steps exactly for any exploit to be successful. (See below For original nlaunch exploit instructions if needed)
1. Download TI-Nspire PC Software 3.2.0.124 from TI website or http://tiplanet.org/forum/archives_voir.php?id=5948, install, and run.
a) Connect both CX calc and PC with the USB cable, if it's not already, and backup all data on CX calc.
b) Find, and connect to the CX calc. handheld through the TI-Nspire PC software by clicking on the lower right icon, where "Select
A Handheld" is found.
2. Download TI-NspireCX versions , 3.1.0.392, 3.2.0.1212, 3.2.0.1219 or 3.2.3.1233.tcc from: http://ti-pla.net/a3717
a) *NOTE* the unit may already have one of these CX OSs already pre-installed.
b) Check under 5. Settings, 4. Status, tab, and About on the CX calc.first if in doubt.
c) If so proceed to step #3 and ignore http://ti-pla.net/a3717.
d) If not, download a suitable OS from: http://ti-pla.net/a3717, and use the TI-Nspire PC Software to install before proceeding further.
3. Download, extract/unzip, nlaunchy CX 2.3 from: https://github.com/Excale/nLaunchy
4. Download, install, and run TNOC from: http://ti-pla.net/a1922
5. Download TI-NspireCXCAS-3.1.x.xxx.tcc from: http://ti-pla.net/a3718 (*Notice* this is the CXCAS OS and not the CX OS)
6. Focus the TNOC program and load the downloaded TI-NspireCXCAS-3.1.x.xxxx.tcc file.
a) The TNOC executable is found here, more or less. C:\x...\TNOC\TNOC_1.24\Windows\TNOC_en.exe
b) Check the Delete boot2 box, then one can optionally delete the samples files in the Example folder, and process. However, this does not delete the Example folder, just the samples in the Example folder.
c) After TNOC'ing the TI-NspireCXCAS-3.1.x.xxxx.tcc file, find, and rename the TI-NspireCXCAS-3.1.x.xxxx_xx.tcc to "phoenix.tns"
d) Select the handheld by finding the handheld icon in the LRH screen in the TI-Nspire PC Software.
e) Add folder named nlaunch under...Documents\nlaunch\ (Left bottom screen area, where -Documents/+examples+MyLib...etc. are)
f) Drag phoenix.tns, into \nlaunch. (Although, any directory under the Document root will work)
g) Drag #3. files from nlaunchCX\CX\ {nlaunch.tns, preloader.tns} into Document\nlaunch.
x) (For trogfield, preloader.tns was skipped because it didn’t come in the file)
7. Put CX calc into Maintenance Options Mode by pressing and holding {doc+enter+EE} . (Tricky) ;D
a) *Note* The calculator can be off, or on for steps #1.- #7. Either depress with by putting it on your leg with a sharp screwdriver or a paperclip in between, then lifting off of your leg. Or take the battery out, then plug it in while holding the three buttons.
b) Then depress and release the reset button on CX calc. back.
c) Once reset shows the TI screen loading bars, then release {doc+enter+EE}.
d) When CX calc enters Maintenance Options, choose 2 to delete OS, choose 1 to proceed, deleting, and then press any key to restart.
8. After the CX restarts, Open TI-Nspire PC Software, if not already opened, with CX calc. connected.
a) When the CX calc. restarts, shows a caution (/!\) symbol, Install OS, and the progress bar is stuck at 60%....
b) Select the CX hand held again by finding the handheld icon in the LRH screen in the TI-Nspire PC Software.
b2) follow step 6e-g if you have forgotten.
c) Drag or copy the nlaunch.tco from the PC nlaunchCX\CX\ into CX calc. Documents\nlaunch\
d) The TI-Nspire PC software will give an error dialog, "Error Experienced a problem while communicating with the handheld. A retry may be successful." but low and behold, it installs the nlaunch.tco anyway on the CX calc. ;)
e) It takes a few minuets for the nlaunch exploit to install the phoenix.tns file.
f) If steps #1.- #8. c). are done properly, the TNOC'ed phoenix.tns "CXCAS OS" file will install and reboot. Then ABC123, blink, then ABC1234 will appear briefly in the upper LH corner of the CX calc, at the restart of the nlaunch.tco\phoenix.tcc install.
g) If not, push the reset button on back of CX calc. again and repeat #8.
9. Once installed, go through all the CX "CXCAS" calc. setup prompts.
a) *Notice* one of the CX system start up prompt says a CXCAS OS was installed. This can be further investigated by checking 5. Settings, 4. Status, tab, and About on the CX calc. to see if indeed the CX is now a CXCAS. If not start over, give up, and reinstall the CX back to the original OS at #2. (Then slowly close this instructional, and walk away very slowly)
b) *Note* If those have made it this far, and have had success, congrats. One is not "Out of the woods yet", Do Not Upgrade the calculator with an OS unapproved by this exploit mentioned in, and, or before this post until it's safe to do so. Mainly 3.2.4.xxxx.tcc OS onward, but others on may render the CX calc. stuck with that OS. Which ultimately means the unit is hard coded with no hopes in downgrading to make this exploit work again, or again it might work. (Per other testimonials)
c) However, my CXCAS V3.2.0.1219 OS works, but not all CX/CXCAS OSs will nlaunch correctly exploit. So read up on what has worked, and ignore what has not been posted as exploitable.

Please don't make multiple posts (https://www.omnimaga.org/index.php?page=Rules) in quick succession unless you have a very good reason for doing so. There's a Modify button on top of each of your posts ;) Welcome to the forums!
-
big posts are hard to read, each is a different topic to be more clear than one superpost.
-
Also looks like im the only one to help people here. If installation works for you, please come back and help others. Dont know how many people use this forum.
We have a decent regular userbase. Not all of them have nspires though or care about putting a CAS on a non CAS system. Personally, I think if you want a CAS machine that's what you should buy.
-
Once again, if you strip out the most important part (HW revision constraints), you'll get people to potentially brick their machines.
Seriously, just link to the official topic, which is on TI-Planet. It gets updated whenever there is a need to, and contains all the proper warnings in red bold etc.
No wonder so many people complain about bricked calcs when they follow unofficial forked tutorials not containing all the info...
This is really starting to get on my nerves.
-
Should i erase what i posted then? Also, it seems like people make one post asking for help, then disappear.
-
Eh, idk, but you should at least link to the original topic, as it will get updated when/if needed.

Hello, I´m from Mexico, studying Mechatronics Engineering. I´ve got a TI CX a year ago. My university didn´t allowed TI during calculus exams, and I was cool with it. However, now I find myself using integrals and derivatives on a more regular basis throughout most of my classes, and I thought it might be useful to install CAS on my TI CX. So, I was wondering if mine would qualify to do the installation.
TI CX
serial: 2169008177 P-0612E
OS Version: 3.9.0.463
Thanks for the help :)
Update:
Ok, I just read that A-I models can work, that´s great.
Now I don´t know if I need/can perform a downgrade...
-
You could install Ndless 3.9 and flash NLaunch(y), there are instructions available for that.
I suggest you to try khicas first, it's free to use, open source and has some more features compared to the Nspire's CAS.
-
I have a ti inspire cs version 4.0.0.235. serial number p-0615v. how can i get cas on my calculator? i need it for my calc class. thanks
-
Currently, you can't.
-
is there a program similar to cas that i can use? can i downgrade my os system to get cas?
-
I can not find any info on how to downgrade from 4.0 any one able to help?
-
Hi, I have used the tutorial from theascen, and have successfully installed CAS on my non-CAS TI-Nspire CX
I was wondering if I can upgrade my CAS software (currently at 3.1.x) to 4.0.0.235 (the current version which has many improvements over the previous versions), without bricking my device? or losing CAS all together
-
The latest nLaunchy supports OS up to 3.9.1.
-
I've been trying for days to use this exploit on my TI Nspire (not cx) running 3.9.0.43 and when I drag over the nlaunch.tno file to the calculator and confirm that I want to install it one of the following happens. It says "please delete 4kb worth of files to proceed" and the install screen on the computer closes, or it says "calculator is busy" or their is no error and on my computer the loading bar in the installation window stays at about half. I've left it over night on each of these and each time the "operation system not found. Install OS now" prompt on my TI Nspire doesnt go away, and the loading bar doesnt move. Does anyone know what my problem is? Also can anyone post a picture/video of what a proper installation/error message looks like.
-
Hello, I've followed the guide written by theascen and was successful up to the 8th step, unfortunately, when I try to transfer the nlaunch.tco to the nlaunch folder after deleting the current OS in the calculator I get an error saying that the OS file that I am trying to transfer is corrupted/not valid and nothing happens from here.
I don't know if this matters but currently my software is 3.1.0.392 and the factory number is P-........D
Any help would be greatly appreciated, as I've tried to do this multiple times already and always end up running into the same error.
-
I have the same problem and am not sure what to do. Any help please?
-
These are the up-to-date tutorial for installing nLaunchy that you should use: https://tiplanet.org/forum/viewtopic.php?f=57&t=13213 (https://tiplanet.org/forum/viewtopic.php?f=57&t=13213) and https://tiplanet.org/forum/viewtopic.php?f=57&t=11019.
Be wary of unofficial tutorials. Most of them are outdated, and one of them caused some people to brick their calculators.
-
Thank you so much. That worked!

Hi
I installed CAS on my calculator.
I want to upgrade my OS from 3.1 to 3.9.
How can I still keep CAS on my calculator?
Thanks
-
Hi, I have a Nspire CX, OS 4.0.3.29 and serie P-xxxxN
Is it possible to change it to CAS?
Thanks
-
