Pixel XL WON'T Charge/Connect to PC

Thanks for your quick Reply.

NO changing to a known Working Ribbon cable DIDN’T fix my problem. and there is No damage to any of the 4 Connectors (2 on the Ribbon cable and One each on the Dock Connector & Logic Board). Since the ribbon is the only one that connects two areas of the phone, so something went bad during reconnecting.the ribbon cable is BARELY long enough to be able to position right on top of the connector once we connect one side of it. So i think one end of the connector didn’t seat Perfectly and Shorted/burned the USB Controller (or whatever) thats on the logic board side) because changing the dock connector board is NOT fixing the phone. So whatever is causing this issue is on the Main board. I think its history. I will update the forum if i find a Working Solution. Hoping for the Best.

Mines intermittent ,I've taken it apart to replace the port and it worked for about 10 mins and stopped. i've also let it charge without the mid-frame in and it works perfectly but as soon as I put the mid-frame in it either doesn't work at all or for about 10 minutes.

This is easy to solve. When you press the mid frame into position it is causing some unnecessary contact giving you the problem. most likely the dock board is not seated correctly. If you think the dock board is seated correctly then cover the underside of the mid frame that is directly above the whole of dock board with some thin tape/paper and see what happens.
