    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?

      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 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...

      Macbook A1932 Some Keys Not Working
      by astroboypaul
      Macbook A1932 had completely dead keyboard. I found liquid damage on circuitry on keyboard itself, and repaired it by replacing what i think was a 10k 0201 resistor (here's my post requesting schematic for keyboard circuitry where I included a photo of the resistor: https://www.badcaps.net/forum/troubl...ic-820-01294-a)
      Now most of the keyboard works and I can login, but the following keys don't work: Delete, "/', left...
