Hello guys, I have been reading this forum and watching Louis videos for a long time and now I need some help so I decided to register.

A client bringed to me his Macbook air 11" 820-00164 early 2015 board which he turned off in the middle of a system update. I have already checked the board and every single voltage is present, but it doesn't POST. I believe efi got corrupted. Is there any place where can I get a clean ME bin file for this board?

Thank you!

We can try first to correct original BIOS.
Read U6100 and upload its dump somewhere, then post the link.
