What is the voltage to ground (not diode mode) of PPBUS_G3H @ fuse F7000? Check both sides.
What is the voltage and current draw of the power adapter of the logic board? Check each USB C connector. Check both sides of the USB C connector. -
It's charging the battery just fine. It doesn't want to power up or complete a revive in apple configuratorComment

I am having issue with macbook pro a2141, 2019. It start with question mark, the only option is internet recovery but it will not go to disk utility mode..just stops on like 1/3 progress bar with apple logo.
When i insert usb disk it will not recognize it, but on usb ports it is giving picture on external screen. It is heating a lot.
I did all resets and only thing left is try to revive it (firmware reinstall) with apple configurator from another mac. I have only macbook air 1466 from 2013. I install apple configurator on macbook air but when i connect usb-c (mac 2019) to usb-a...08-28-2022, 12:26 PM -

Hi. I think we have a candidate for our first DFU macbook with a 'critical update error' message (A1706).
With regret, we do not seem to have a machine to mate to a suitable host to run the Configurator 2 tool.
Any suggestions on such a box ? The latest models are quite expensive on Ebay and such.
We do have a macbook with the older style Thunderbolt connector - can we purchase a Thunderbolt to USB C cable and run the same tool ?
The system details does show a THUNDERBOLT controller on this other macbook.

Hi All,
Judy doing some research on whether anyone's ever been able to resolve this. Seen quite a few examples and most have just gone eh guess it's dead, but surely there's something we can try?
For instance, I'm working on a 2020 now with this error. Logiwiki says error 75 occurs when the system is in recovery mode but when I connect it to apple configurator it does show up as DFU so that doesn't seem right. When I try to restore it gets up to step 4/4 and the bar gets to the S of system then that's where it gives that code. Apple configurator then sits on "apple... -
I've got a macbook air A1932 here which a customer abandoned. I'd like to get it running so I can sell but having difficulty. I ran it in DFU mode through apple configurator, and chose 'Restore' and it went through to step 4, then it looked like it was making progress when all of a sudden the large, grey EFI lock showed on Apple configurator. Isn't DFU supposed to reflash the firmware?
I have a DS-809SE but there is no SAM port on this board. Also, I removed the board and examined but didn't notice any BIOS-looking chip.
Where to go from here?07-14-2023, 03:03 PM
