EFI firmware dump for the MacBook Pro 15-inch Touch Bar, model A1707, logic board 820-00281-10-A. The 820 prefix is Apple's own logic board numbering, with the suffix giving the revision. The 8.00 MB size matches the 64 Mbit SPI flash used on these boards. Technicians reprogram it to fix boot failures or firmware corruption. These images can carry machine serial data and lock information, so keep the original read safe and check that the board number on the PCB matches exactly.
