Okay, great. X1001 is the culprit here, right? Judging from the PCB
it's located in the bottom shielded area at the top right. There are
three pads, the big right one is ground I assume which of the left
pads, the top or the bottom would be the one that is connected to
OSC32K_IN and do I need to remove C1051 in order for this to work?
