Hi. I have an HP Pavilion g6-1321 and I flashed a modded bios (Insyde) for it to unlock the power menu. and while the flash was in fact, successful now if I change ANY of the settings in the bios the laptop won't boot and I just get a black screen (as if it was bricked) I can recover from this by simply removing the CMOS battery. but it's useless if I can't change any settings. Does anyone have any idea on what's going on? Thanks in advance and best regards.
