don’t try installing any other android than stock, you will not be able to use your tablet. you probably just need a new battery.

Yeah, touch is always the issue, i even tryed one of those desktop android builds like phoenixos and it all worked except touch and wifi. Chuwinreally used non standard parts in this one

I have not because i have read online of experiences like you had. I gotta ask, did you try the driver backups for the 32 bit version?

Also, 2 gigs is not enough for a x64 os, at least not if you wanna run anything at decent speed.
