  2. 2

    Heat Lower Glass

  12. 12

    Pry Up Charging Board

    2 min

  13. 13

    Transfer Rubber Gaskets

    2 min

    Use tweezers to peel the microphone rubber boot off the old board. Move the gasket onto the microphone port of the new replacement board.

  18. 18

    Reconnect Battery Cable

    1 min

    Press the lower battery flex connector down into its socket on the board to restore power connections.

  19. 19

    Reinstall Speaker Housing

    2 min

    Place the speaker assembly bracket over the lower board and press down to align it with the screw holes.

  20. 20
