Should i erase what i posted then? Also, it seems like people make one post asking for help, then disappear.

big posts are hard to read, each is a different topic to be more clear than one superpost.

--------------------------------------------------------
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.

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.

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.

Dont know how google sharing works. maybe it does, maybe it doesnt.
on page 8 of https://www.omnimaga.org/general-calculator-help/installing-cas-on-ti-nspire-cx-non-cas/60/
 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.

General Calculator Help / Re: Installing CAS on TI-Nspire CX Non-CAS
« on: April 20, 2015, 09:52:15 pm »
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!!

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!


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!

L model cannot run CAS
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.
As i understand, non cx Nspire have similar codes to CX, so check the model.
The conversion is possible:
¿Can I do this with TI-NSpire with touchpad? and... What about if I want use a recent o lastest version of the OS?
Is it possible to install this on a TI Nspire Clickpad?? I've been able to get NDLESS on this... If that helps at all. *.* *.* *.* *.* *.* *.* *.* *.* :banghead: >B)

Hello guys!

I'm new here, I'm from Dominican Republic
My NON-CAS Firmware is 3.9.1.38

And I want to know if is possible to install it CAS.

Please, I need your help.
Cannot on M calculator:
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.

OS Version: 3.6.0.546
Hardware Version: P-1213M

TI Calculators / Swapping CAS with CX hardware in shell.
« on: March 21, 2015, 03:37:54 pm »
Has anyone tried swapping out the components of a CX and CAS? I have both and just sold my broken CAS, so I dont have the ability to do it and leave it... Unless I swap it out and sell the CX as a CAS to some unsuspecting person on amazon... Probably some of the pegs are not lined up. There is a visual difference in one of the bottom corners.

« on: December 12, 2014, 10:16:51 pm »
Basically, your calculator should be able to use nLaunchy and OS 3.1 through 3.9. Hardware J and higher now can downgrade from 3.9 to 3.6 but not 3.1 and they can't use nLaunchy.
who are you responding to? im gonna post board pics after recovering from a long day.
