Firmware archive for the Apple MacBook Pro 15 inch A1707, board code J80G, labelled as the main logic board image. The name ends with a source site tag but gives no 820 board number or firmware version, so confirm compatibility yourself. Mac EFI chips are rewritten with an SPI programmer after desoldering or using a clip. Back up the existing chip first, since it holds machine-specific serial and configuration data. Also check that the image size matches the flash part fitted to your board.
