    Macbook A1932 - ran restore in DFU, but lock icon halfway through?

    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?

      Macbook Pro DFU Restore Issues
      by Flasman90
      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)]

      Water damaged MacBook Air A1932 AmrestoreErrorDomin Error-9 trying to restore with configurator
      by dbuergi
      Hi all,

      this Macbook was stuck at 5v and didn't start because of some water damage. I was able to clean everything and the board started. So i put everything back together and the Macbook seems to boot with 20v, 1,4A and 29W. So i decided a DFU recovery. At 50% of the system repair i get the error massage from the title. Display stays black and no Apple logo. Both repair and recovery don't work.
      Is there anything i can do?

      Macbook Pro A2338 820-02020 Stuck on RESTORE MODE
      by lab10.haifa
      Good day, friends. Got this problem with M1 macbook - it starts, chimes, tries to boot and stuck with a message "support.apple.com/mac/restore"
      It works with DFU mode, but it's cannot be restored. With "revive" function - same problem. Internal restore mode doesn't work, as well as Internet Recovery.
      There is no damage on the motherboard. No short circuits.
      Could it be a NAND problem? (but usually, if NAND is dead - mac simply wouldn't turn on)
      Thanks....

      MacBook Air A1932

      Hi, I've never worked with a MacBook before, so I need some advice.
      I have a MacBook Air A1932 (820-01521). When I plugged in the charger with an amp meter, it showed 19.7V and 1.9A, which indicates that it's charging, but when I press the power button, it doesn't turn on. So, I disassembled it, disconnected the battery, and plugged in the charger again. It showed 19.6V and 0.04A, and pressing the power button had no effect—no current draw at all. Then, I removed the motherboard, connected the charger again, and got the same results. I took a multimeter and checked all the coils, and everything...
