Firmware dump for the Apple A2251 MacBook Pro on logic board 820-01949-07, taken from chip location UB260 and stored in a 538 KB RAR archive. Apple identifies logic boards with 820-xxxxx numbers plus a revision suffix. A small chip like this usually holds support firmware rather than the main EFI, so programming it needs care with the correct device type. Read and keep the original contents first, and confirm both the 820 number and the UB260 designator on your board.
