About this board

A1708 SCHAMATI — motherboard 820-00480-A.

What this thread covers
  • EFI firmware (full SPI ROM dump)
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no boot or no chime after a firmware update, a firmware (EFI) password lock, or a corrupted ROM after liquid damage.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search 820-00480-A in File Finder.
