[FR/EN] Downgrade Nspire OS 3.9 CX / ClickPad

[FriedTM]

I am curious as to why in both the ndless 3.9 and the downgrade fix monochrome touchpads are not supported? Is there a reason why?

[Adriweb]

Apparently, the hardware acts differently and makes things fail - maybe it will be fixed/workedaround one day, though, so it can be installed there as well.
If the Ndless team gets a version that works on the TouchPads, we'll make a topic about it anyway

Hey,
Any news about the possibility to downgrade Monochrome TI-Nspire TouchPad? I find out now, after upgrading my calculator to 3.9 via TI that i can not jailbreak it after the instalation.
Cheers

Nothing new to my knowledge.

The only way for Touchpad models is not user-friendly :

• remove the OS trough the maintenance menu
• reflash Boot2 1.4 through RS232
• install Nleash
• and then you can install any compatible OS

Where can i find any reference to that method of dumping firmware(or bootloader?) unto the calculator?

[Lionel Debroux]

You can find such a reference on TI-Planet, in the downgrade tutorials

I have a cx non-cas running 3.9.1.38 and it has a U as the final letter. It won't let me install the uninstaller please help I have tried multiple times and watched videos but nothing seems to work .

[Adriweb]

Ndless 3.9 will work on your OS, no need to downgrade.

[Cionow]

But wont ndless 3.6 games not work as they are for 3.6, Adriweb?

[Adriweb]

Most should work, as they tend to be "3.6 or later".
As long as they don't use very OS-specific things, it's OK.
