Re: A1708 820-00840-a efi lock
you didn't understand ... did you use the clip from the programmer ?? or did you remove the chip from the motherboard, before you wrote the bios chip ?? did you not write another physical chip, but it was written with errors for certain reasons..how did you proceed to read and write the bios chip ??Leave a comment:
