A1706 flashing was created by nixer
I have 2 non Touch Bar machines that I have cleared the password on and they both give black screen after either writing back the modified dump or the original non modified (after the modified didn't work)
The chip was desoldered from the board and flashed directly.
What am I missing here and what steps need to be done to correct it.
I believe the machine verifies the checksum of the EFI on boot? Is this true?Can the checksum be repaired?
Some light on this would be greatly appreciated.
