How can I upgrade my TI Nspire CX II CAS to OS 6.2 instead of 6.3 so I can use Ndless? Help is appreciated. I already have Ndless r2020 and OS 6.2.
At the moment, you can't downgrade your CX II from OS 6.3.

That is downgrading, and unfortunately you cannot downgrade (or upgrade to a lower version as you say) an OS.
If you can find it, there are usually releases of all(?) versions of the nspire os on our friends-across-the-pond's site, TiPlanet:

Are you looking for any tutorial on installing an OS on the Nspire? E.g. You're on OS 6.1 and want to upgrade to OS 6.2?
