Hello everybody,

So Ive got an interesting problem. Ive never come across with a Chinese made baord before. I cant get it to BROM and root it. Has anybody had any experience with these kinds of boards? Ita from a LAUNCH X431 919z OBD2 tablet that the sellers (ebay chinese) refuse to assist with after it locked out the serial number against their custom alpine linux POS firmware. Any help in gwtting this board to BROM wpuld be appreciated so I can dump the files and inspect in Android Studio for why its locking me out from operating the OBD function via serial cable.
This is supposedly a $600 piece of hardware!!!

Sorry for the crappy photos im doing on the fly can upload some more when Ingwt home :-).

Thabks for any help in advance.
