Firmware dump in a 7.52 MB ZIP for the Apple MacBook Pro 13 inch, EMC 2555, Core i5, read from an MX25L6406E chip, a Macronix 64 Mbit (8 MB) SPI flash. A technician uses it to restore the EFI ROM with a programmer when the board has a corrupted or locked firmware. The logic board number is not stated, so confirm the 820 number on the PCB. Save the original chip contents first and make sure the target flash is also 8 MB.
