Firmware dump for the Apple MacBook Pro 15-inch A1398 from the 2013 and 2014 generation, logic board 820-3787 revision A. The ZIP is about 5 MB and is intended for rewriting the EFI boot ROM on that board. Typical uses are clearing a firmware lock, recovering from a corrupted ROM or fixing a board that will not chime. The 820 number is etched on the logic board and must match. Dump the original chip first so the serial number and other system data can be carried over to the new image.
