There was some liquid damge, thats all fixed.
The board trys to boot, vcore comes on for about 1 sec, and then it reboots again.
Similar to when their is some sort of bios damage in earier series of boards.
The battery when connected loads PPBUS down to about 10V, however amp meter shows about 1.4A being drawn, until it cycles again.
I'll try a DFU revive tomorrow, and if no luck last resort in a ultrasonic bath.
Mac is stock on 20V 0.3A.
Its stuck in recovery mode in Apple configurator 2. It begins installing the system using system restore. The outputs
"failed to recive message from device, might be a connection problem with usb host) [AMRestoreErrorDomain - 0x9 (9)]
Anyone managed to recover from the error?
I have about 10 T2 macs here with the same fault. All with very minor liquid damage in various places.
This certainly has turned out to be the anti repair chip.
Any ideas? before i launch these across the car park....!!
