Hi guys, I've downgrade my CX 3.6 to CX CAS 3.2.3.1233 folowing this tut (http://www.omnimaga.org/general-calculator-help/installing-cas-on-ti-nspire-cx-non-cas/msg383792/#msg383792).
I have few question and I hope you help me with, I'm pretty new to modifying CX/CAS .
Q1/ Since I run CX CAS 3.23.12233 on CX can I install needless and have 3 party app ?
Q2/ Can I install CX CAS 3.9 the the last OS on CX following the same tut I mentioned above ?
That's pretty much it for now. Thank you.

Hi and welcome to the forums :)
Q1: Nope, Ndless requires a copy of OS 3.1 or 3.6 to be installed.
Q2: Don't install OS 3.9 if you plan to use Ndless. There's no way to downgrade back to 3.6 if you do so (except with extra hardware if your calculator is old enough and even then it's not guaranted)
I recommend OS 3.1 or 3.6 personally.

Ok, how I could remove the current OS (CAS 3.2.3.1233) and Install 3.6 ?
Keep in mind I use CX handheld.
Thank you.

Do you mean the non-CAS CX handheld? I unfortunately don't know how to switch from a CAS OS back to a non-CAS one if you have the non-CAS model, but if you meant the CAS model, then there is probably an option somewhere to locate the OS file on your computer. I think it's a .tco file (or .tcc if you got a CAS model). Just don't use the Find updates/Update unit options in the menus because that will install OS 3.9, which you don't want to happen.
If you literally want to remove the 3.2 OS before installing 3.6, then you need to access the maintenance menu and remove the OS from there. I forgot the key combination, though since I don't use my TI-Nspire CX much. It's probably somewhere online or on the forums.

tbh I'm very confused now. :'(
1-Well my handheld is non-CAS and I installed CAS 3.2
2- What I need is Can I remove CAS 3.2 and Install CAS 3.6; so I can have ndless and CAS on non-CAS.
Thank you for your time ;D

Ok I think I found it: https://github.com/Excale/nLaunchy
In the readme file, you need to follow the Uninstallation steps. Also, to access the maintenance menu, I found the key combo and it's Doc+Enter+EE. While holding these down (your fingers must be 15 inches long :P), use a pen to push the reset button on the back and keep holding the Doc+Enter+EE down until the maintenance menu appears.

AFAIK it's not possible right now to use 3.6 CAS on non-CAS HW.
