Where can I get Ndless for 3.6? I have a TI-Nspire CX rev. D
Also, does it really work? Because I don't want to get screwed and being locked in 3.6 if Ndless doesn't work...
Well you don't have to update, you can keep the OS 3.1
You can also have both the 3.1 and the 3.6 on your calc using nlaunch(y) in case you still prefer the 3.1 for some reason but need the 3.6 for some other reasons.
