Can you tell me if this EFI is specific to the 2017 EMC 3178 or is this for any 820-00165 board? I have an EFI ROM file from a 2015 board and it doesn't start up on my 2017 board. I have heard that the EFI for this model is specific to the 2017. Can someone confirm this either way?

if you have the same board, change the Serial Number S / N, and clean the region me, and do the test, don't forget to do before writing on the chip, a backup of the original bios of the laptop.

What was pulsing on / off?

Please post more details.

Very possible that you have a defective battery.

Restore your bios and post your voltage rail that is pulsing.

Did you make a bios backup before you started ? .MEInject isn`t recommended for anything over ME 6 in my opinion,and certainly shouldn`t be used with apple ME fw . Post the original bios backup

Hi, I' ve this MacBook Air with a strange problem. This laptop come in to my shop with initial problem PULSING (ON/OFF, no fan)

I wrote this attached bios dump that I clean me region by ME INJECT software and Macbook Power on but have a strange defect.

The Macbook Power on only when I connect the AC adapter without battery. It Never power on by clicking power key on keyboard. I also tryed to power on by SMCbypass on the motherboard.

When Macbook is ON and I press ON/OFF key the macbook go off without problem

I tryed to clean me region using FIT but I can't find efi payload for this model MBA7,2.


Can anyone help me?
