i think my xbit keeps losing it bios becuase it stops working sometimes and sometimes it needs to be flashed so many times and sometimes it works without flashing? does anyone know why its doing this? i've had my xbit almost 1 year without problem.

How do you know that it needs flashing? its far more likely that the pogo pins are just coming out of place, then when u flash it you are moving the xbox, sometimes knocking it back into place.

I would blame the pogo pins before the bios chips
