Hi all, Yesterday, I use method described in thread: [TUTORIAL] AMI Aptio UEFI Advanced Menu Unlock - Bonus MSR unlock! h ttp://forums.mydigitallife.net/threads/54523-TUTORIAL-AMI-Aptio-UEFI-Advanced-Menu-Unlock-Bonus-MSR-unlock!, to modify one Pad's Aptio V BIOS. Unfortunately, in last step, I use command for FPTW but AFUWIN to flash back: fptw -F bios_mod.rom -BIOS The result is, system do NOT boot any more. Is there anyone knows that, this situation is so called "Black Brick"? I mean, it can not be recovery by any software method, except for Hardware solutions to changed BIOS's content? And, I am interested in the real reason. Dose anyone can confirm that, using wrong Tools is the Key for such result? If so, it means AFUWIN follows other rules to update something like verification checksum, is that the case? Any clue for it in technical? Any comments are welcome!
