Re: macbook a1466 emc 3178 help figuring out how to dump/flash my bios/efi
would a ch341a and a j6100 adapter for it be good enough to read and write data to bios/efi chip?Comment

Re: macbook a1466 emc 3178 help figuring out how to dump/flash my bios/efi
hello again
i have bought ch341a programmer and also have bought the adapter clip to plug right into the service port on the motherboard. i cannot get the ch341a software to recognize the chip and i cannot dump the chip either.
any help would very much be appreciated at this point, i have pretty good soldering skills. i feel like i need to supply power somewhere but i am not sure, and i cannot find alot of documentation on this specific model.Comment

Could someone help me?
I have a Macbook Air A1466 EMC 3178 - 2017, board 820-00165 and sometimes the boot interrupts with an image of a folder and a question mark.
Could it be the BIOS? -

Hi everyone.
Macbook Air A1466 EMC 3178 (board 820-00165 A) not turning on and no charging light. Completely dead. With no battery connected it would power up and I could hear the chime, but nothing on the screen and then a sudden turn off. Sometimes during the chime. Opened it up and found some liquid damage. The flat that connects both boards has damage in one side (with a missing pin already). The connectors on the boards are fine, though.
Also, there was liquid damage on the included picture area, which are R8111 and C8111. A quick and soft brush on it made the resistor be gone....04-15-2024, 01:24 PM -

Good night!
I have
Macbook A1466 2017 EMC 3178 A-820-00165-A
It was bad soldering SPI before (I guess somebody have been trying to fix it before)
I have found problem, it runs, but when I am trying to install OS it is interrupted.
I think error is here:
panic CPU caller 0xffffff0014a8c5c0
Would somebody can help me to find what problem is?
Thank you...12-28-2022, 05:09 PM
