Downgrade For Ti-nspire os 3.9 released
« on: November 02, 2014, 04:40:18 pm »
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:

Also tutorial link: http://tiplanet.org/forum/viewtopic.php?f=57&t=15497&p=172096#p172096 (might be useful to the many people who come here for help to downgrade)

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.

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.

I added the diags menu "bug"fix ("Go to OS mode") on the tutorial, 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.

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.

It was a translation of the original news article from ti-planet. It wasn't translated when geekboy posted the news.
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.
