[Q] Problem with flashing ROM(s)

Hi, I have tried to flash warious ROMS on my unbranded Allwinner Q88 tablet, but every time I try flashing a ROM with livesuit, it says "Upgrade fails : 0x162". I have tried 20 different ROMS now and i'm always getting that error.
Now for some reason I installed CWM recovery, which gives me the problem that I can't boot the tablet, it will only boot into CWM recovery. Is there anything i can do, or should I just throw it out? Hope you guys have some ideas..
