Board cycles power on then off and back on and stays running so it seems like all is well but no boot. Tried swapping the U6100 to see if any difference. Medusa couldn't read chip so pulled J6100 - no change. Wasn't able to clean me yet being Medusa didn't work but I'm thinking this means possibility of spi trace broken... I havent seen that personally, but know not uncommon for this board. Do the traces usually break from one side to the other side? I was able to verify connections to nearby resistors on the U6100 side.

There are several tiny traces which connects SPI Bus Series Termination resistors.
Many of these traces are inside the board, going under PCH area, or to other side, close to J6100.
You must check all traces continuity and resistors value.

PLT_RESET_L stays high?

Yes PLT RESET L stays high and I also all over 3V: RTC_RESET_L, PCH_INTVRMEN, PCH_INTRUDER_L, PCD_SRTCRST_L
