820-02020 20v but no boot

[Outofwhack]

No corrosion visible.
Fan full speed when in case with all peripherals attached.

ppbus_aon 12v
pp3v8_aon 1.8v
pp3v3_aon 3.3v
pp5v_aon 5v
pp1v8_aon 1.8v

Presuming your advise might be to do a dfu restore I checked to see if I can get it into DFO mode....
With 2 microswitches wired to board to apply 1.25v to soc_force_dfu and ground pmu_onoff_I I can only get LOCK SYMBOL to appear in AC2 but not DFU

Press power switch 5-8s, until lock symbol disappears.
Then try to put the machine into DFU.

Im able to get the Macbook into DFU mode with the board back in the case.
Unfortunately both revive and restore end up with unknown error 21.

How to go from here?
