Disconnect the ribbon connectors. There are two on the right and two on the left. Flip up the tabs and pull out the ribbons. Be careful of the wifi antenna wire on the left. Again, it is soldered to the board and the flat harness under the board.

Remove four small Phillips screws on the lower end of the board. Lift from the top of the board and pull up and out. From here you can fix the micro usb port. This will require micro soldering. If you cannot do that, you need to find someone to do it for you. ;)
