Hello guys!

820-01700-A stuck at 20V 0.05A originally liquid damaged, other store cleaned board (no corrosion) and reflowed U7800, U1200 and U9580

PPBUS_G3H: 12.55V
PP3V3_G3H_T:3.3V
PP5V_G3S: 5.1V

No short to ground on any other coil.
No voltage on any other coil

Any idea?

Thanks!!

Can be seen in DFU?

 

[javier_herart]

I cant get it in DFU mode, do I need to have the battery present to enter DFU?

 

[2informaticos]

The board can get into DFU without charger even.
5V through USB-C from AC2 machine is good enough.

Check if you get all AWAKE and SLPS2R voltages.

 

[javier_herart]

Will check. What is AC2?
