TI Calculators / Can't install Old operating system Ti-nspire CX (Help)
« on: November 22, 2015, 01:37:27 pm »
Hello,

Just tried to downgrade my OS to install Nlaunch , but seems like i cant get lower than 3.6 ,

Number behind (20xxxxxxx4 P-xxxxxC)

Boot1: 3.0.0.99
Boot2: 3.2.4.7

I have tried to instal This one 3.1 (https://tiplanet.org/forum/archives_voir.php?id=3717) And This one 3.2.3 (https://tiplanet.org/forum/archives_voir.php?id=9676).



All the time i get error ( M7 You cannot install a version of the OS that is older than the currently installed version.)


Never mind Solved this!!! MODS YOU CAN DELETE THIS THREAD!!!!!!

The process is entirely reversible, with basically no signs left. Nlaunch CX will actually install the real CAS OS for you, so it'll be fully functional. I'm actually looking for the install guide and the executables also, so bear with me.
Also, just as a side note, the process of installing a CAS OS on a non-CAS calc is a bit of an edge case of piracy, because you're paying less and get more. It also shouldn't be used for cheating. Of course, I'm not implying you want to do that, but just sayin'

Oky , also my Calc model and verstion are good?

Also what's the main difference between Ti-Nspire CX and Ti-nspire CX  CAS ?

https://github.com/BASLQC/BASLQC/wiki/Nspire-Nlaunch-CX    this guide is bad?

You can install the CAS OS with Nlaunch CX, I did that. However there might be some limitations on that that I'm not aware of. I'll leave that to the other, more knowledgeable users.
Thanks for answer,

There is instruction how to do it?

Also Derivatives , (Calculus ) and Graph anlysis will work?

Also i will be able to backup it to factory OS latter? or its final?

Hello,

Some days ago purchased New Ti-nspire CX , but then realized that i need CAS version.

Here some specs:
Version: 3.9.0.463
Number behind (20xxxxxxx4 P-xxxxxC)

Some questions:

1) It's possible somehow to get CAS on this?
    *) How hard is installing?

2) If installation fails can i get back to my original OS?

3) It's possible to broken calculator?

4) If i some how get CAS , Do i lose some functions in calculator ?

5) Is it worth do do it? Or better purchase other?

Best regards,
