Re: Macbook Air 820-00165-A schemati and boardview
Hi
A clean me region will not remove efi password...If you have a dump with a efi password upload it and i will remove it and i will tell you whats needed to be done next so the cloud don't reset it again. The other way to remove a efi password is with a donor bios so let say it a 8mb file the top have 4mb is merged with the bottom half of the donor and all you need to do after is replace the serial to match the original. I have a way to do it with out touching the original file i just remove password .
