Clean firmware dump for the Apple MacBook Pro A1707 with logic board 820-00928A, reported as tested and fully working. Apple's 820 numbering identifies the logic board design, and the letter suffix marks a revision. A clean image is used to replace a locked or corrupted SPI ROM, for example to remove firmware issues on a donor board. Read and keep the original ROM first, since it contains the serial and network data, and confirm the chip size before programming.
