TI-nspire running CAS but shows up as normal

→ **MyCalcs** profile · by **alexmiranda5179** » 05 Nov 2022, 00:46

it has CAS functions and they work but I can't update the os with normal or CAS and it doesn't accept CAS files from my computer.

How can I keep the CAS but update to 3.9 so I can get the better graphing capabilities?

Hello.

Anything special written on the screen while the calculator is rebooting ?

What's the calculator datestamp ?
Is the short 6-7 characters code written on the back at the right of the serial number.

Thanks.

it says 1021005075-k-0709b on the back and shows pp1234 on the top left corner of the screen when its loading operating system

Hmm, K-0709B that's rather rare. We'd be interested in pictures of the PCBs/motherboard if you're able to open it (screws might be hidden below the rubber feet, I don't remember)
