  3. 3

    Heat the rear panel

  6. 6

    Slice the perimeter adhesive

    3 min

    Slide the pick slowly around all edges of the rear cover to cut through the glue. Reheat the edges if the pick begins to catch or stick.

  7. 7

    1 min

    Use precision tweezers to pry up the small coaxial antenna cable head from its terminal on the sub-board.

    2 min

    Slide a flat spudger beneath the lower sub-board and lift it out of the phone recess.

    Clear the microphone channel

    2 min

    Inspect the mic port opening on the bottom of the phone frame and remove any dust using tweezers or compressed air.

  14. 14

    Position the new sub-board

    2 min

    Place the replacement sub-board into the lower recess, aligning the rubber microphone gasket directly over the port hole.
