I think you need to start holding the 3 keys down before pressing the Reset button and must not release them until the maintenance menu appears.

As DJ said, you have to press the keys before resetting and hold them until the maintenance menu appears. It should appear when the progress bar is a bit more than half full.

Oh wow, I probably should have realized that...
Thanks a bunch! I now have 3.1 installed :D

I'm going to start of by saying I'm a idiot and I don't know what I'm doing.So I just pulled my TI-nspire CX CAS out of the box and I have looked up everything. I have the TI planet guide to ndless and the GBA emulator but not for the life of me can I find out how to find out my current OS or delete it to download 3.1. I have pressed and held down [doc(down arrow)][EE][enter] but I dont get anything. Is there a doc button that I'm missing because you all just put[doc] but I cant see one without the arrow. Thank you for any help.

You're pressing the correct [doc] button.

Did you do it exactly like that?
If you're doing it correctly you should see the booting progress bar on the screen while you are holding down the 3 keys.

Edit: You can find out the current OS version by choosing "5 Settings" from the start screen and in the menu that comes up "4: Status".

lkj thank you for your help but literally 1 minute after I was playing around trying to figure it out and I found what you edited your post with. Factory settings has the calculator start with 3.1.blah blah so I already had the right OS. Then I went ahead and installed everything and now I am playing zelda. Thank you for your help anyway.

Make it clear for everyone : You don't need to remove the OS in order to downgrade from 3.2 to 3.1 It makes much more useless steps for beginners.
Just download OS 3.1 from the list here for your calculator (pay attention to the Nspire type - Clickpad, TouchPad, CX, non CAS, CAS, CM, etc ..) :
https://tiplanet.org/forum/archives_list.php?id=OS+Nspire

Open TI-Nspire Computer [Link/Student/Teacher/Navigator] Software or TiLP and send the OS as if is was a basic .tns file.
The software will recongnize it as an OS and install it automatically.

Please try to stay relevant. This is useful information if you're trying to go from 3.6 to 3.2, not from 3.2 to 3.1. Wrong versions.
