My Nexus would no longer charge or sync with my PC
Simple, just carefully remove the back from the Nexus, remove 6 screws holding the Usb board and unclip and remove all the cables attached replace the board and reverse the process. Took 5 Min. and now its perfect again.
The hardest part is removing the back take it slow and gently work your way all around the case. (and remember Youtube is your Friend)
