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

Hi there,
I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.
You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
This daughterboard uses an interesting...04-21-2025, 11:41 PM -
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 -
Does anybody have one of these yet? It looks like it just has a $5 esp32-c3 processor and then a few resistors and other components..Probably $10 to get pcbway to print it out, but I need access to the firmware and haven't been able to find it anywhere online. This allows individual users to perform screen repairs on apple laptops by avoiding the need to use apple parts (and thereby gaining acces to their configuration utility) and retain the open/lcosed sensor capability for the screen. I'll post the circut board files here if I can get a copy of firmware, no point in doing the work until I have... -
I have a 2020 Macbook Pro A2289 and after many attempts managed to get it into DFU mode, using my older 2017 A1706 Macbook Pro (Running Ventura 13.7.8). However, when attempting 'Restore', it fails at step 4 of 4, showing the following error:
- "The operation couldn’t be completed. (AMRestoreErrorDomain error -1 - Failed to handle message type StatusMsg (Generic error)) [AMRestoreErrorDomain – 0xA (10)]
- "The system cannot be restored on this device. Failed to create new state machine for restore [com.apple.MobileDevice.MobileRestore - 0xFB1 (4017)]
