When I received my first nano a white gecko clone, the first thing I did was drop it with the dinky microusb cable plugged in. The entire usb connector pulled off and was basically destroyed.. So I did a cludgey fix. I took a scrap piece of PC board and made four islands on it using a Harbor Freight 3/8" spot welder cutter bit.(#63657). Th hen cut one end off an old type A USB cable.and attached one end to the scrap PC board and soldered the leads to the pads. Then I used a small gauge enameled wire and attached to the traces remaining from the old micrusb connector traces. This is the hard part. I cheated on the ground wire and attached it nearby as shown. After I was satisfied I covered the fragile connections in epoxy. The enameled wires are terminated on the other end on the appropriate pad. Its ugly but really pretty usable. Could be improved in a hundred ways. If you wanted you could probably fashion this into a PC board case. Your board could be different so double check where everything goes. I am just throwing out the general idea of how it might be done.
