Have you flashed this clone before with a working bios ?
If yes what flashing tool did you use ? (Evox , Spiderflash cd , Xflash etc )
What flashing tool did you use to flash the new X2 bios ?
Flashing the X2 bios should not kill your chip , It must be the flashing tool you used i think and the way the 2 banks are split.
