iPhone X boot loop issue

I am a technician with the skills and access to microsoldering equipment. I am trying to avoid separating the two board layers if possible because it is a pain to get back together and may not be necessary. The phone is doing a 3 second boot loop. I have tried to turn it on with only essential components plugged and I have frankensteined new hardware in order to rule out hardware issues. It is recognized by iTunes. I attempted every reset possible, and none of them work. When attempting to restore the iPhone through iTunes, the restore stops right after extracting software (likely because of whatever is causing the boot loop). On the board level, are there any pads I can test in order to confirm that I need to split the boards? Does anyone have a clue what might be causing the issue? On my USB detector, the output reads a stagnant 0.47A @ 5.09V
