Tried DFU?
If not recognized, check if all AWAKE and SLPS2R voltages are present.

Did you check diode mode after each chip removed?
I suppose only one was bad...

Yes, finally I found a short on CD32 chip and i replaced it. All chips are good now, but i unfortunately i reballed the T2 chip with the upper side, Without any need.
Now i have 5v0 and 0.2amps and after 10 sec it drops to 0 amps.
All voltage are good on the sequence diagram until ssd voltage.
SSD_PMU_RESET_L 1.8V
PP1V8_SSD 0V
PP0V9_SSD 0V

Try DFU revive; let see if SSD comes on.
Should be recognizex in DFU, even no SSD voltages present.
All AWAKE and SLPS2R voltages must be present.
Check diode mode to ground on SSD power rails.
