Macbook A1466 A820-00165 CHECK my BIOS please
I have panic CPU caller, I guess it is EFI problem.
Macbook A1466
EMC 3178
A820-00165-A
serial FVFWQ0B7J1WV
May be dump was from different version A1466, because
SPI had traces of soldering and was soldered lack of contact.
In-build apple test is OK (ADP000)
I can choose download source, but during the downloading system crashes.
Here is my SPI dump attached. Help me please.
Thank you in advance.Comment

Re: Macbook A1466 A820-00165 CHECK my BIOS please
Try the bios at posts 13 and 44 ,both have clean ME firmware ,all you need to do is add your serial number using a hex editor,and modify the fsys checksum.
https://www.badcaps.net/forum/showpo...43&postcount=5
4.3. Apple
For 2017 and older machines, serial number is stored in Fsys store of BIOS and can be edited with hexadecimal editor. Fsys checksum needs to be fixed afterwards
Search for "ssn", edit the serial number, save, open dump in UEFITool, go to the Fsys store and write down the suggested checksum in the panel on the right. Checksum is 4 bytes at the end of the Fsys store, between one zone of 0x00 either Gaid or another zone of 0xFF, it must be written in reverse order (so last 2 characters from UEFITool must be written first).

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 -

I'm hoping someone can help me with a 2017 MacBook Air A1466 820-00165 that is running very slow. This is a board that I picked up on ebay recently.
This is not being caused by a sensor issue. All sensors report normal operation and the fans run at normal speed. Geekbench gives me a single core CPU value of 124, when it should be closer to 400. I was unable to complete an install on the SSD without putting it into a different computer first.
The board appears clean with no sign of liquid damage. I have done a PRAM and SMC reset, and I have done a reflow of the SMC. I have inspected... -
I have a 13 inch MacBook Air 2017 that does not show any life, however, there is activity from the MagSafe light going from green to orange and staying. Normally, this battery works perfectly fine and it can actually charge the battery as if I were to leave it alone it would change to just green, however, this thing does not boot up at all, I was told the computer was at 30% and then it randomly shut off.
Some voltages:
PPBUS_G3H - 8.5V
SMC_PM_G2_EN - 3.42V
PP3V3_S5 - 3.32V

Hello there
I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.
I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.
