    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    Howard,

    Glad you found it. Did you apply solder to the pcb track to fix it.

    Post a pic.

    Yes mate….sure did ��
    Reckon the pressure of the USB cable on the on board USB socket was twisting the RR header which cracked the track.

    Just a tip for you guys who solder small distant spaces like this as well as micros. Solder all 4 corners so the device won't move in the next step. Solder/short the entire connection, do it fast when soldering a micro and let it cool. Heat and drag solder wick soaked in rosin/flux across the terminals to suck up all the extra solder. Practice on something you don't care about if unsure.
    When finished, it will look like a machine soldered it.
