    820-01598 - A2159 Unable to load Mac OS

    Sorry for the delay in reply. Yes, we can start internet recovery. But the system crashes when it starts installation. We've double checked nand voltages, 0.9, 1.8 & 2.5. all present. We thought we found a short on 2.5Nand but it was an error in diagnosing. Could this be nand failure without...

    820-01598 - A2159 Unable to load Mac OS

    No Data to Save. Have tried a DFU restore, but it doesn't load the OS onto the Mac. Is it supposed to automatically reinstall the OS after being restored? After successful restore, the host mac shows a lock symbol. The restored mac shows nothing but when rebooted goes back to folder flashing.

    It has no OS & administrator account, I believe it's been previously restored. It gives us the message: Recovery is trying to change system settings: No administrator was found. Is there anything else we can try?

    Hi Team, I've got a 820-01598 which is showing a folder logo. Checked all SSD voltages and reset lines, all good. Understand we can't just boot from a USB installer on these T2 models. I've tried Catlina internet recovery installation, while plugged via ethernet, it allows me to select the...

    820-00840 No Display

    This device came through for a 'FlexGate' repair however when we have checked the lcd connector J8500 we're missing all the EDP lines.. I've not yet come across a device with all the EDP lines missing so not sure if this is game over as the EDP_ML lines show value but the cpu is showing heat in...
