Hi there! I'm having trouble with this 13" MacBook Air. The computer turns on, fan spins, all power rails OK, but no chime, no backlight, etc.

So, I removed the U6100 and soldered one from a non-identical non-donor board, and it works "OK"*, so... The firmware is corrupt.

Does anyone have a clean ME dump for exactly this BIOS (820-00165-A EMC2925, Early 2015 i5)? I can change serial number and write it (got a CH341A).

Thank you!

*OK means the computer turns on, chime, boot extremely low, etc., but works at least...
