No power. No boot. No DFU. Voltage rails all good until S5.

trying to fix this A1932 820-01521. no power no boot.

All the rails in power sequence up to a point of getting SSD voltages are there along with PPDCIN _G3H 20,5V, all AWAKE, SLPS2R & SLPDDR.

Device is recognized with forced DFU but every attempt fails with error 9.

Where do I go from here?
