Nleash: Take Back Control of your Nspire
Posted by Travis on 31 July 2010, 01:43 GMT

When TI announced Nspire OS 2.1, we reported on users' discovery that the update activated a seemingly permanent block against reverting to OS versions older than 1.7. In response, Olivier Armand (a.k.a. ExtendeD) has released Nleash. Nleash will forcefully remove both the downgrade protection and the installed 2.1 OS, allowing the user to reinstall any desired older version. For instance, OS 1.1 can be installed in order to run third-party C and assembly software through Ndless 1.x (which supports only OS 1.1).

Hello guys!!!

I've got the TI-nspire CAS Handheld with touchpad. I upgraded my os before I read about ndless and the problems with version 2.1...
Ok, now I know that the current ndless version doesn't work on my handheld at all because of the 'wrong' keypad, but I used nleash and downgraded my os anyway. I tried to send a version that supports ndless. But something's gone wrong... ^^ Now an incorrect or incomplete os is installed on my handeld which makes it (after loading) turn off and on and off and so on... The biggest problem: because of that I can't connect my handheld to the computer anymore so I'm not able to send a different os...
PLEASE, HELP ME...
What can I do now? I hope I don't have to contact TI 'cause they won't be too happy about me using 'inofficial' software... =)

Thank you!!!!!!!!!!!

Same thing has happened to my calc. The only way I can use it is with the 84 plus keypad.
