T114 (V2) I can't change settings

Hi, I have a T114 (V2) and I can’t change its settings. It can’t be accessed via Bluetooth, serial port, etc. I’ve tried resetting it in every way possible but it doesn’t work. I can’t do a new program or update either, it refuses to enter programming mode. Does anyone have a solution for this?

hi @oh8gkp Heikki

what firmware are you testing?
