Stuck on DFU 820-01041 A1990

[Pumemule]

Hi,

i got a computer that came not powering on, tried to DFU, show error 53.
Any idea what to look for?
tried to rewrite the soc t2 chip, still the same.

The apple screen stuck until power off by force.

Any history available?

Check diode mode to ground on SSD power rails.

No history, got it as not working.
no water marks, or something visible.
when power on the trackpad clicks but nothing else.

Diode Mode:
PP2V5_NAND_SSD0 - 0.36v
PP0V9_SSD0 - 0.13v
PP1V8_SSD0 - 0.37v

SSD1 nothing because there isn't one

Test DFU with an empty (erased) Soc ROM.
