Yes, 2 different original chargers, one 96W, another 61W, 2 original Apple cables, one USB-C USB-C another Thunderbolt 3 Thunderbolt 3. All give same results. Also, machine enters DFU state, but does not complete restore. T2 gets a little warm.

You probably have damaged traces on internal copper layer, underneath UB300.

All AWAKE and SLPS2R voltages must be present and stable, for DFU to work.
SSD voltages must also be there; or come on at least after DFU revive.
