Apple firmware image for logic board 820-00165, revision 02, zipped to 4.48 MB, with Clear me in the name implying a cleaned or reset dump ready for programming. The 820- prefix is Apple's own logic board numbering. Such binaries are written to the SPI flash on MacBook boards to recover from corrupted firmware or a locked state. Confirm the 820 number on the board, read and keep the original chip contents since they hold serial data, and verify the image size matches the chip.
