Firmware image for the Apple MacBook Pro Retina 15 inch, model A1398, in a 4.54 MB RAR archive. No logic board number is given, and the A1398 spans several generations with different 820 numbered boards, so match the board number on your PCB to the contents before use. Such files are programmed into the boot ROM SPI chip to recover from corruption or failed updates. Always read and store the original chip first, as it contains serial and model data, and check that the image size equals the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
