Released today, the tiny utility "DowngradeFix 3.9" finally allow lets you reinstall OS 3.6 on your TI-Nspire CX or TI-Nspire CX CAS running OS 3.9 (3.9.0.461 or 3.9.0.463). And indeed before you ask, the old black & white TI-Nspire ClickPad and TouchPad are not supported yet.
Installation is very simple - as explained in the how-to below, you will simply need to open the file, reconnect the USB plug, and send OS 3.6 !

Therefore, today is the day Ndless 3.6 is brought back to life !
Students are again able to properly do their school work for computer science with Micro Python and its editor pyWrite, exams candidates to test the new PDF document reading solution with nPDF, and everyone will be able to relax with the Nintendo Game Boy Advance emulator and nDoom!

Wow, now that's great news! I am surprised it didn't take longer to be honest, seeing as downgrade protections get stronger and stronger. I'll have to check this out. What impresses me even more is that this appears to work on hardware J and higher too (although of course OS 3.1 will not run on those so they'll have to use 3.6)
Good job to the authors of this! :thumbsup:

It's just 4 bytes in the NAND. To disable the protection just overwrite it with 0x00000000, it's that simple! The nice thing is that the OS is so dumb that it doesn't even check the OS version that should be installed against its own, so you can install 3.6 directly from within 3.9.
I'll have to check this out. What impresses me even more is that this appears to work on hardware J and higher too (although of course OS 3.1 will not run on those so they'll have to use 3.6)
Well, it's meant for HW >J as other HW versions can already be downgraded with nLaunch, else it would be a little superflous...
-
Don't older hardware calcs still require an RS232 adapter if they have OS 3.9 installed, though? I though the nLaunch trick only worked with OS 3.6 and lower.
-
Amazing. Suck it, TI.
-
I added the diags menu "bug"fix ("Go to OS mode") on the tutorial (https://tiplanet.org/forum/viewtopic.php?f=57&t=15497), useful for certain calcs only.

Agreed. I was always thinking that if you had a new calculator, you'd have to wait until ndless 3.9 is released. This is such a quick solution that's easily accessible to everyone. Now everyone can enjoy the benefits of ndless!
-
Yeah same. Downgrade tools have been more and more rare as new OSes came by because of all the tricks that TI tries to pull on us, so in some occasions, we were stuck with no way to downgrade until the next version of Ndless came out and when the next Ndless version came out, it was quickly followed by a new TI OS or was for an older OS.
-

Tbh, everyone was thinking that. We even recently turned down some people who asked for how to downgrade OS 3.9. I might send them a PM to tell them about this.
Again grand kudos to the creators of this hack!
-
Well I replied to them to let them know, but only recent topics I could find in various sub-forums.

The decision to release a downgrade utility was made to avoid uselessly investing time into an upgrade of Ndless for this OS version which doesn't bring us anything new, and which would require much more effort.

Hmm, geek or another staff/admin, you might want to insert the front page news inside QUOTE tags because apparently it was copied verbatim from the original english post on TI-Planet, which they see as plagerism: http://tiplanet.org/forum/viewtopic.php?f=43&t=15498#p172161
Although the credibility of Omnimaga remarks coming from that site is questionable now, copying a news article verbatim without the author's permission/followed guidelines is a bad idea. I certainly wouldn't like if my news articles were copied on other sites without my permission, unless they were just quoted with cited source.
Perhaps start the news with "Quoted directly from http://tiplanet.org/forum/viewtopic.php?f=43&t=15498", put Critor/TI-Planet news in the quote author field then finish it with the standard source link would be better so that people don't get ideas. That would also prevent possible legal issues since both sites are big.

:o
It was a translation of the original news article from ti-planet. It wasn't translated when geekboy posted the news.Granted, instead of "site: [...]" he should have written "source: [...]", but that's it (and also corrected some small grammatical mistakes).
The posts after critor's are just bitching about omnimaga. Critor could just have posted here or mailed that he doesn't like the way this had been cross-posted.
I can only hope that this relationship doesn't get worse, as I like both sites. I'm mainly here, though, as I don't speak any French and it's not really a solution to use a translator.

I'm pretty sure it was (otherwise it couldn't have been the same words/sentences), however the actual link to the specific english version wasn't written at the top of the post at that time. But the english version was still accessible if you enabled the global english flag on ti-planet (top right of the site). The post now shows the fr+en links.
But anyway, copy/paste verbatim (without quoting, that is), is, indeed, not acceptable.
(Or a newly written article could be posted, with no need for quoting etc., just the source - which was apparently what Juju was supposed/about to do, but Geekboy posted the topic before he could)
The posts after critor's are even worse, just bitching about omnimaga. Critor could just have posted here or mailed that he doesn't like the way this had been cross-posted
Well, admins/staff from both sites know about the situation anyway, without the need for critor to post here (which he won't, like others, for other reasons some time ago - but you don't seem to know the whole story (which isn't necessarily a bad thing), so yeah, that could appear as bashing with no reasons, while in fact, there are. But that's not the topic here ;) )
as I like both sites
and a lot of other people do, so yeah, to those able to write/edit news items, it'd be good to fix that problem quickly so that this whole thing can be over soon...
Edit : oh well, Lionel replied also (to you) here : https://tiplanet.org/forum/viewtopic.php?p=172189#p172189 in which he says the same as me here, pretty much
(Edit 2 : Also, English is not a problem on TI-Planet if you/anyone want(s) to post stuff there - contrary to posting french or another language here on Omni, which is understandable)

Oh I didn't know it was translated from the French news (although I wonder who wrote the first translation? Unless Geek used Google Translate). Everything went on so fast that when I saw the news was nearly identical to TI-Planet's, I thought it was really copied from TI-Planet's English translation. I think that if a news editor translates a news from another site, he should perhaps post it like I suggested, though (or if he's worried about the news being too long, then put a link saying it was translated from original post on TI-Planet). After all, a translated news still holds the original content.

Exactly, like in the IRC logs.

I know something about it and I could also notice some of the disrespect, but this now is just exaggerating beyond human levels :-/

Really? He posted a reply to my post on another thread on another forum? That's just childish.
(Edit 2 : Also, English is not a problem on TI-Planet if you/anyone want(s) to post stuff there - contrary to posting french or another language here on Omni, which is understandable)
I know, but at least 80% of the posts I want to read are french, even those from parisse who wanted to get some help with the toolchain. Especially French is hard to translate if it contains mistakes like missing "`"s.

In the IRC logs it looks like that The_King translated it.

I'll let you compare both texts so you can see it's actually the same (+ even the same typos, that since have been fixed (?) ) :)

Edit :
@Fabian : Oh well, maybe when you first visited it, it wasn't fully translated yet, sure - but that's not the issue here anyway.
-
I know, just the formatting is missing. All I know about this are the IRC logs and that it was only barely translated at the time I wrote the IRC message :(
-
I guess no hard feelings should be held against whoever suggested/translated the news and perhaps reposted the result on the front page with the source. Editors just gotta make sure in the future to verify their news source in case they might be copying the content by mistake, else members or visitors will get ideas. ;)
-
From what I can tell from the conversation at TI-Planet, apparently someone copied the translation and gave it to Geekboy.
then again my french is really bad so I might be misunderstanding things.

aeTIos: It WAS me kk I never hide that fact but I hate when someone is talking about me and pretend not know it was. I am sorry for my mistake pls just dont make it an issue
PS: I am not doing that stuff again
-
This whole thing can be solved by properly quoting the content - why should there be more talk....
-
This is pretty awesome news, even though I don't have an nspire.
I find it funny how we keep find exploits in TIs software to allow ndless somehow :)

-
It's quoted via the site at the bottom, And I got it from The_King under his statement that he translated it. Apologies for the headaches, But not my fault! That being said site has been changed to Source: Shy of that not to worried about the rest the content is there and that is what matters. It is nice to finally have tho!
-
Well, at least the source was there since the very start which is good. I guess one solution is to check if the other site doesn't have an existing English version of their news on their front page to avoid any confusion. Or perhaps wait a few hours before relaying the news in case, but in the current situation this was very important TI-Nspire news so waiting was not necessarily a good option.
Congrats again to whoever made this downgrade utility. :) Last night I have notified new members who were seeking for an OS 3.9 downgrade utility in the last few weeks.
-
When I had posted it I had no clue there was an English page available, Nor did i know Ti-planet was viewable in English. Just learned that today! But yes bravo extended another wonderful job :p
-
Ah ok
On a side note, I am surprised that Texas Instruments didn't release a new OS yet since this downgrade fix exploit came out. Normally, it just takes 1 hour or less. <_<
-
I tried using this, but after i opened the .tns file and connected my nspire to the computer, it said "downgrade protection disabled" and now the computer doesn't register the calculator is plugged in, even other nspires don't acknowledge the connection

Reboot the calc and try again, some attempts may fail.

Maybe their fix is not a real fix and they just want the ndless-publicity. I can't belive TI programmers are that dumb :P .
-
It's nice that it came out for new users, even though I won't need it since I have an Nlaunchable calc and I'm still running is 3.1 anyway. :P
-
It's nice that it came out for new users, even though I won't need it since I have an Nlaunchable calc and I'm still running is 3.1 anyway. :P
Same here, I'm mostly still developing for 3.1. Mostly because 3.1 is much faster (especially file transfer in nspire_emu) and also to ensure backwards-compatibility. My calc runs on 3.6 for school reasons ("domain" function mainly)
-
Same, but I might switch to OS 3.6 + Nlaunchy soon because I'm getting a bit tired of how much slower Lua is in 3.1 and the fact most Lua developers no longer really want to support OS 3.1. It's just that when I do it I really want to have enough time and dedication to make sure I am doing it right.
-
I don't run any lua on my calc and I don't use it for school so I prefer to use OS 3.1 since I can debug on-calc pretty fast. I just need to get myself an UART.
-
What would be an UART? Also yeah one reason why I stay with OS 3.1 is how even without nLaunchy I still don't need to re-install Ndless every reboot. Saves a bit of time considering the Nspire startup is already long to begin with. OS size is also a factor :P
-

The "new" SDK has a feature to redirect stdout to the display with nspireio. It shouldn't conflict with other libs trying to access the display ;)

RS232 serial connection over CMOS levels in this case :P

The 2 MB or somewhat aren't really an issue and startup time is not an issue either. The solution is pretty easy: Just install nLaunch and you can use both.
-
An UART is nothing else than a serial adapter. :P The thing you can use for reprogramming the boot2 but it also lets you communicate with the running program if it implements debug code.
Oh Vog ninja'd me.
And I didn't know about that. Does it work on OS 3.1 ? I don't want to upgrade because of all the reasons. :P
-

And I didn't know about that. Does it work on OS 3.1 ? I don't want to upgrade because of all the reasons. :P
Yes, all programs compiled with the new sdk work on 3.1 as well if they don't use any incompatible features explicitly.
-
Thanks for the clarification on the UART thing. So I assume it serves the same purpose as an Arduino and an RS232 interface when it comes to Nspire stuff?
Also for me 2 MB is a lot of space, especially with that many Lua games and GBC ROMs installed and startup time is an issue as well. The TI-84+CSE boots in 1 second, the HP Prime in 3 seconds and ClassPad II in 3 seconds, yet the Nspire sometimes takes 45 seconds to do so (if it starts at all, because in two occasions in the last few months it got stuck with the clock icon)
But yeah, the main good news is that we can finally easily get rid of OS 3.9, which makes me happy no matter what. :D
-
There is a huge process that needs to be followed before TI can release a new OS. They need to test, distribute and make sure that there aren't any big regressions in the new build (bad updates have bricked devices in the past, they don't really want that happening again).

Yes, and you can see the (what I believe is) the build number. For 3.9.0.493 it's probably 493, so they did clearly have some work on building and testing...
-
Can somebody please help me? For some reason, my calculator does not want to register after I launch the downgrade program and the program says that downgrade protection is disabled. I keep resetting the calculator and the computer to no avail. I am using a Ti-nspire cx and ti-nspire computer link to downgrade from the computer.
-
Have you followed every instruction steps on the TI-Planet tutorial? SOmetimes, one step being missed is enough to either cause the whole process to fail or even permanently damaging the calculator.
Do you get any error message? Also what is the OS (including the last digits) and hardware revision letter on the back of your calculator (in case it's a very new revision would have patched this exploit shortly before it came out)?

That's a known problem, it happens sometimes (and some some cals more often than on others, weirdly) and the easiest way to cirumvent this is the following:
- Run downgradefix
- After the message is shown, hold Doc-Enter-EE and reset the calculator while still holding these keys.
- When the menu shows up, uninstall the operating system and it will reboot.
- On the next reboot you can now install 3.6.
At least in theory it should work, haven't tried it myself.

There is no update yet, AFAIK.

That one line just made my day XD
-
17 days later, OS 3.9.1 is discovered (and it blocks the downgrade, although it's most likely not a direct counter-measure to the downgrade utility, since it's so soon after it's release. That's unless TI devotes $1 billion worth of budget on employee payroll just to block exploits in less than hours.) http://tiplanet.org/forum/viewtopic.php?p=173079&sid=4e9969230e7d88d6d242a4f52e1e2df5#p173079

Welp, that sucks x.x
I hope that one will be able to break soon, too ^.^
Also, 7000th post
-
Wow, that'd be kinda ridiculous if they knew about the downgrade tool AND had a fix for it, but they may have been working on OS security all along and just fixed some 'bugs'
-
I'm having an issue.
I used this downgrade program on my nspire cx hardware revision S. Installed OS 3.6 and runned perfectly. But when I ejected the USB from the computer it stopped working. Everytime I try to boot it starts showing a loading clock at then the calculator shuts off. All the times!
Surprisingly, the calculator works when connected to computer.
I uninstalled OS 3.6 and re installed OS 3.9 but IT KEEPS WITH THE SAME PROBLEM! The calculator only works when is USB-connect.
I searched and another user on TI-Planet with hardware revision S is with the same problem.
What should I do now?
-
Try the maintenance menu and format everything. You can also try to play a bit with the diagnostics utility, that could give us a clue what might be causing this.
It may even work to take the battery out and wait for a few minutes and try again.
-
Ok, reinstalling OS 3.9.1 instead of OS 3.9.0 solved my problem. It's a really strange issue. I wonder what should I do to get ndless on my calculator :/

Quote from https://tiplanet.org/forum/viewtopic.php?f=57&t=15497
If your hardware revision is 'S' or above, your calculator will not work correctly with OS <3.9.1, making the downgrade useless.
Therefore, you'll have to wait for a new version of ndless (compatible with 3.9.1) to be released before you can use it.
