Hello,

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).

Make sure your calculator model supports the specific OS version you're trying to install. Some OS versions are only compatible with certain hardware revisions of the TI-Nspire CX.

Is this software still working? I'm considering upgrading it to the latest version but am worried it might have some bugs.

Did you attempt to patch the OS file with tools like Nlaunch compatibility patches or downgrade enablers before installation?
