About this board

This thread is for the IMac A1312.

Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.

What this thread covers
  • EFI firmware (full SPI ROM dump)

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 IMac A1312 in File Finder.
