OS 2.1 NleasheD & 50000 forum posts
« on: July 27, 2010, 06:48:01 pm »
For the next 10 seconds, or if TI is slow and takes a bit longer to prevent so, it may now be possible to downgrade your Nspire from OS 2.1 to an OS older than 1.7. As reported in the previous OS 2.1 news, by Critor, the new OS by TI added an hidden anti-downgrade protection inside your TI-Nspire, blocking any downgrades to OS 1.1 (required to run Ndless 1.0) through 1.6. This protection was permanent: even if you downgraded to OS 1.7, 2.0 or 2.0.1 afterward, you still could no longer install an older one again. It was over: no more Ndless 1.0.

Could this have changed today?

Nleash, by ExtendeD, part of the Ndless dev team, is a tool that allows you to break the anti-downgrade protection on all TI-Nspire models. Even on the Touchpad, it is now possible to install OS 1.1, but you will need a clickpad keyboard from a regular Nspire, as explained by Critor from TI-BANK:

Quote
You need a ClickPad keypad to use your black TI-Nspire with OS 1.X.

On the TI-Nspire TouchPad CAS, two additional tricks are needed, because you can't easily plug the ClickPad keypad, and the OS won't boot successfully with a ClickPad keypad.
If you keep the TouchPad keypad, the arrow keys won't work, and the rest of the keys will be all messed up...

Everything is explained in the TI-Bank news -> http://ti.bank.free.fr/index.php?mod=news&ac=commentaires&id=844

 Remember that those tools are still new, though, so please use them at your own risk, especially if you have acquired your hardware recently!

How long will TI take to counter this one, now?  ::)

On other news, the "new" Omnimaga forums has finally broke the 50000 posts milestone a few days ago and to my surprise, July is now the 2nd most active month in Omnimaga history. Approximately one year ago, Vegeta was breaking his scouter on our post count. On the old board, it took over 5 months longer to reach 50000. Traffic on the forums still appears to be up, too.

My activity may also remain sporadic for the next days to come, due to several reasons, so bear with me if I take a long while to reply to important topics.

Bravo ExtendeD!  Truly we cannot be stopped by The Man, much less TI! Downgrade protection?  What downgrade protection?

And its good to see you back Dj :)

YES! This was pretty quick, too.
Congrats to ExtendeD and the Ndless team :)
Now if only RunOS or Ndless 2 would magically appear...

Yeah, that took a bit of my time yesterday, although I got owned badly (1 wins vs 6 losses... I wonder why they ranked me in the silver cup. My guess is that when I played the ranking matches, my teamates were really bad. In fact they never bothered to build any defense and expected me to defend them the entire time, wasting all my ressources x.x)

For all those people with the touchpad nspire non-cas: You can buy clickpad keypads from TI for $10 a piece, (though it will look a little weird in regards to the color scheme) and use ndless!
