ROM dump of the T2 SoC for the 16-inch MacBook Pro A2141, logic board 820-01700. The 6.87 MB RAR holds firmware read from the T2 storage, which repairers use when restoring a board whose firmware chip has been corrupted or replaced. Apple numbers its logic boards in the 820-xxxxx format, so match the number on the PCB exactly. T2 data is tied to security pairing, so keep the original dump safe and expect that a donor image may not restore full functionality.
