[critor]

Version française, English version

Joyeux Noël ! Mis à jour aujourd'hui suite à la récupération de l'OS 3.9.1 pour TI-Nspire CX non-CAS, le petit utilitaire "DowngradeFix 3.9" vous permettra enfin d'installer l'OS 3.6 sur votre TI-Nspire CX non-CAS munie du dernier OS 3.9.1.38.
Hélas, cette mise à jour ne rajoute toujours pas le support des anciennes TI-Nspire monochromes ClickPad et TouchPad.

Merry Christmas ! Updated today following the TI-Nspire CX non-CAS OS 3.9.1 dumping, the tiny utility "DowngradeFix 3.9" finally allows you to reinstall OS 3.6 on your TI-Nspire CX non-CAS running the latest OS 3.9.1.38.
Unfortunately, this update still doesn't add support for old TI-Nspire ClickPad and TouchPad.

L'installation en est de plus ultra simple comme détaillée dans le tutoriel ci-dessous - il vous suffira tout bonnement d'ouvrir le fichier, de reconnecter la prise USB, et d'envoyer votre OS 3.6 !

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 !

Par conséquent, les toutes dernières TI-Nspire CX non-CAS à ce jour vont pouvoir elles aussi bénéficer de Ndless 3.6 !

Therefore, latest manufactured non-CAS TI-Nspire CX up to date are now able to benefit from Ndless 3.6 too !

Les Terminales S et étudiants en disposant vont enfin pouvoir libérer tout le potentiel de leur achat pour travailler correctement leurs cours d'informatique avec Micro Python et son éditeur pyWrite, et les candidats aux examens et concours avec calculatrices autorisées vont pouvoir tester la nouvelle solution de lecture de documents PDF avec nPDF !

L'OS 3.9.1 n'étant pas publié sur le site officiel de Texas Instruments, le support de l'OS 3.9.1.38 pour TI-Nspire CX CAS ne pourra être rajouté que lorsqu'une personne en disposant l'aura dumpé en suivant notre tutoriel et communiqué à l'équipe Ndless.

As OS 3.9.1 has not been uploaded on TI official website, support for the TI-Nspire CX CAS OS 3.9.1.38 can't be added unless someone owning such calculator dumps it using our tutorial and shares it with the Ndless team.

[Thatguy]

Whenever I install the 3.6 firmware from the downgrade, the calculator crashes when I disconnect from the pc. A little help please.

[critor]

Did you try again ?
The crashes are random.

[Thatguy]

When I downgrade, if I keep the calculator plugged in the computer, it works fine. When I take it out of the computer it crashes. it works again when I plug it back in. I tried to reinstall the 3.6 os but I was fruitless in my attempts.

[critor]

What do you mean by "it crashes" ?
Just try to reboot the calculator without the USB plugged.

[Thatguy]

Crashing like it turns itself off and then when I turn it back on it goes through the progress bar and when it gets to the spinning clock it shuts down again.

[Thatguy]

My nspire still refuses it work without the usb cord.

[Adriweb]

What if you reinstall OS 3.6 while it works (well, you need to plug it anyway to install it, so...), wait until it finishes, unplug it, reset (reboot) ?

[critor]

What if you launch the diagnostic software ?
What if you disconnect the battery for some seconds ?

[Thatguy]

Nothing's working.
