possible explanation is that this output is firmware/configurable pin which is turned to ground per default but it is really questionable claim.Įssentially anytime you see something that communicates with T2 not function, a DFU restore may resolve. some sources claim that PP3V3_S5 power output might be 'shorted' to ground(10-50 Ohm) if there is T2 iBoot&BridgeOS corruption.5V 0.2a>0.05A loop and no battery charge, unable to DFU from keyboard (SoC Rom corruption).

It is hard to tell why, but many devices stuck in G3H/T2 state are being repaired after revive. One of weirdly common reasons for currupt BridgeOS firmware is corroded TouchID connector. waterdamage on TouchID / Power button connector.Revive is enough to perform CleanME, so if you swapped CPU for data recovery, you can first backup with Target Disk mode, then try revive and full boot. Whis will put uninitialized ME image to BridgeOS partition. CPU / PCH replacement: since ME+EFI image is located on BridgeOS partition, to do classical 'clean ME' procedure after PCH swap, you need to do full DFU restore.Looping apple logo with no loading bar after waterdamage on power button (820-00850 confirmed case).Unable to successfully create computer account and log in after erasing and reinstalling (M1 computers specifically).Unable to boot into the current OS Internet Recovery using command + option + R.

If you found this page, probably you are suspecting T2 issue, so even if DFU won't help you - DON'T REFLOW T2.ĭFU on Beta software might brick the device so keyboard method wont work anymore, however it does not seem to affect anything if you do jumper method DFU.ĭFU mode is needed to restore the T2 firmware when:
