Help with TI NSPIRE TOUCHPAD Downgrade

Unread postby MrRapalo » 10 Aug 2019, 23:58

Hello friends, it is a pleasure to greet you. I would like to know how you can download from OS 3.9 to 3.6 on an Nspire touchpad TI, I have researched on the forum page and I discovered that through a USB / TTL interface you can download to OS 3.6, I have managed to download boot2 to its version 1.4, but now I don't know how to install the SO 3.6. I hope you can help me. :)

Hi.

You should be able to install the latest 3.9 OS on your TI-Nspire TouchPad.
Why do you need OS 3.6 ?

Hello critor
To be able to install the CAS system on my calculator, but I have already managed to install it using nLaunch. Being in OS 3.9 I need to downgrade to OS 3.1 or OS 3.2 to be able to run a CAS system, but in TI-NspireTounchpad the digital tool does not work, so you must use a USB / TTL interface to download Boot2 to version 1.4 to run nLaunch . Use this post to do it viewtopic.php?f=57&t=11019

That how-to is outdated.

Just use Nlaunch CXM, it'll work with OS 3.9 too :
