Hi guys . I have a AllWinner A31S tablet with 4.2.2 but the manufacturer (portuguese brand called Growing) dont have any updates. The Telclast P88s has the exact same specs and i tried the offcial 4.4 of P88s on my tablet but i got a black screen on boot.
Its possible to port the 4.4 Teclast rom to my 4.2.2 tablet ?
My tablet is Growing GTQ818
