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.
