Any other diffrent model board that i can take from?
It is only a trace; run a wire and rebuild.
Did you test and no continuity there?

Then XW8410 is good.
You should try changing U8400.
Be sure all solders and traces are good.
May need to replace all surrounding resistors.

If no data on SSD, then try DFU restore, instead of revive.
If you need to recover the data, start in Target Disk mode and check if can get access to SSD.

Can you acces its SSD in Target Disk mode?
Turn off the T2 machine, and start it in Target Disk mode.
Do not enter into DFU again.
