    1 min

    Use fine tweezers to gently pry the white coaxial antenna head straight up from its socket on the charging sub-board.

11. 11

    Remove Charging Sub-Board

    2 min

    Gently wedge a flat spudger under the charging sub-board to break the underlying adhesive, then lift the board out.

12. 12

    Apply Flux to Port Pins

    2 min

    Apply a liberal amount of soldering flux across the micro-USB anchor points and rear contact pins on the sub-board.

13. 13

    Desolder Damaged Micro-USB Port

    5 min

    Apply heat with the soldering iron while using desoldering braid to pull solder away from the anchor legs and pins, then remove the old port with tweezers.

14. 14

    Clean Sub-Board Pads

    2 min

    Moisten a cotton swab with isopropyl alcohol and scrub the solder pads clean of burnt flux residue and remaining debris.

15. 15

    Solder New Micro-USB Port
