820-01041: No powering on. P5VG3S_EN - 0.0v

[macRepairAmb]

Have this board that originally had corrosion damaged and PP20V_USBC was at 5v. Cleaned all up. Replaced U9080 and U9580, both were shorted out. Now PP20V_USBC is now at 20v but no current is being pulled. I'm getting 0v @ PP5V_G3S.

P5VG3S_EN - 0v
PPBUS_HS_3V3G3H_T - 12.2
PPBUS_G3H - 12.2

Any suggestion on where to start on this?

If you get the AWAKE and SLPS2R voltages, then try DFU restore.

Tried DFU restore and just never comes on, causing the DFU to faulted out after a while being stuck in install state.

Did you try as explained here?
Is the best guide at the moment...

Yep. Tried both revive and restore and both gave me the same message. It goes through the install process and just sits there for a while then gives the error. See picture.

I was thinking you cannot access DFU at all.
That guide says sometging about this error, I think.
Search on Internet about that error, may find more information.
