I'm pretty sure you can. Here's a link to TI Planet's list of OS's. http://tiplanet.org/forum/archives_list.php?id=OS+Nspire Just find OS 3.1 and you're good.

Have fun with your GBC!

When I do all of this it says it has finished installing the OS but when it starts up my version is still 3.2! D: help please I'm brand new to this calculator. I've had it a day and accidently updated it.

A rather cynic answer to somebody who's doing his best.

Maybe I like stairs now. ;)

Well if I am installing 3.2 again the website has the file labeled as 3.1. Because I definitely downloaded the file labeled 3.1 and installed it. I'm so lost and confused. The same happened when I tried to install 3.0 rather than 3.1. So I am thoroughly confused.

Given that TI-Planet links to an OS hosted on TI website, it could be very possible that TI updated OS 3.1 links with 3.2 OSes or accidentally swapped them.

Sorry to bump an old thread, but I didn't want to start a new topic when it's already been done.
I have a TI-Nspire CX CAS with OS 3.2, looking to downgrade it to 3.1

This may seem like a silly question, but how exactly do you wipe the OS completely?
Followed the first two steps and nothing happened.  I already have the 3.1 file on my computer, I just need to know how to put it on my calculator to install it.
