Thank you, I'll try. Waiting for 2 new BIOS chips, as I managed to damage the original one.

Re: Macbook Air A1466 EMC 3178 - no power

Hello guys!

I have a Macbook Air A1466 EMC 3178, S/N: FVFTMBQJJ1WL, with password on EFI.
I dumped the EFI ROM using a 3.3v modified CH341A.
Attached are the initial read, the file modified by me and the read after the flash from the chip.

I installed the chip back but the laptop won't start.
The charger has green/orange light, SMC reset works, but no fan spin, no chime, nothing.
In the process, one resistor flew away and was replaced, nothing else (R6130, replaced with 43.2Ohm1%).

Can you, please, check the dumps and see if they're correct, I'm not sure that the one I've modified is correct. Maybe that's why it won't turn on.
One thing to mention, before removing the chip, the laptop was working and booted successfully.
