Hi. Buddy and I was having some fun with our Nspire CX and CX Cas, when he upgraded to 4.0 and I to 3.6.
I installed Ndless 3.6, and he tried to install 3.9.

Mine works awesome, his doesent. Can he downgrade 4.0 OS from Nspire?
To the people who are programming; thanks!

OK. So, I cannot for example delete OS total and re-install 3.6? Better off selling it and get a new one? hah

Deleting the OS won't help at all, as this won't remove the minimal installable OS version entry stored in NAND, outside of the OS zone.

Are you saying that you are on 4.0, and you successfully installed Ndless 3.6 Or you updated to 3.6 and also installed Ndless 3.6? While your buddy is on 4.0, and failed to install Ndless 3.9?
