No, it's not. One button. The files that don't say EVT are the ones that work.

Also, the serial number was scratched off of the calculator with some knife. But the calculator is EVT1 and the touchpad is DVT1.

We already have it (CAS2.0 DIAG FOR ASIC 2009-8-19)

Interesting keypad ADC value (80, not 73): https://cdn.discordapp.com/attachments/ ... 111136.jpg

Hi!
I'm a newbie with ti calculators..
I just ordered nspire cas w/ touchpad from ebay and was sent with OS v2.0.0 (was working super fine)
so I went into ti website and downloaded and upgraded the ti to v3.9.0.463

booted up and found almost all keys (except esc tab enter etc ) messed up with wrong keymap. I think it thinks it is clickpad

Cant move up down left or right basically can't do anything..
I was just able to scroll down pressing random keys to find the version in About

Boot1 Code Version: 1.0.1.8916
Boot2 Code Version: 3.0.1.131

on the back of the calc, it says NOT FOR SALE DVT1P2-0910
and on the back of the touchpad it says DVT1-1390809

Can you please help me with clear guidance to solve this problem?

wait a day or two, I will finish a permanent very simple fix which does not require any hacking/downgrading/ndless

If you remove the keypad, what's written on its back ?
Anything with EVT/DVT/PVT ?
Thanks.

Got this one, DVT1 071 P-1209 :

Might be a little more recent than yours.
But it's different, touch arrows never worked, not even with 2.0 OSes.

Absolutely. We just need a little tool to be finished. Don't worry.
