Step-by-step

1. 1

   Eject the SIM card tray

   1 min

   Insert a SIM eject tool into the hole next to the SIM tray on the left side of the phone. Push firmly until the tray pops out, then remove it completely.

2. 2

   Soften adhesive on the back panel

   2 min

   Use a heat gun or hair dryer on medium setting to warm the outer edges of the rear panel for 2 minutes. This softens the factory perimeter adhesive.

3. 3

   Attach a suction cup to the lower back panel

   2 min

   Press a suction cup firmly onto the lower portion of the rear panel, just above the bottom edge. Pull upward steadily to create a small gap between the back panel and the frame.

4. 4

   Slice the rear adhesive seal

   4 min

   Insert a plastic opening pick into the gap created by the suction cup. Carefully slide the pick around all four edges of the back cover to separate the adhesive.

5. 5

   Lift off the back panel

   1 min

   Gently lift the back panel away from the phone body. Set it aside on your clean workspace.

6. 6

   Remove the upper frame cover screws

   3 min

   Use a Phillips #000 screwdriver to remove the screws securing the upper motherboard shield. Store the screws in a organized tray.

7. 7

   Disconnect the battery press connector

   2 min

   Pry the upper frame cover off using a spudger. Use the flat end of a plastic spudger to gently lift the battery flex cable connector straight up from the motherboard.

8. 8

   Remove the lower speaker cover screws

   2 min

   Unscrew the Phillips #000 screws holding down the lower speaker assembly over the microphone board.

9. 9

   Detach the lower speaker module

   2 min

   Insert the point of a spudger beneath the corner of the speaker housing and carefully lift it off the frame.

10. 10

    Disconnect the interconnect flex cable

    1 min

    Use a spudger to pop open the press connector linking the main interconnect cable to the sub-board.

11. 11

    Unclip the antenna coaxial cable

    2 min

    Use fine-tip tweezers to gently lever up the gold antenna cable connector from the sub-board. Do not pull on the wire itself.

12. 12

    Pry up the microphone sub-board

    2 min

    Insert a spudger underneath the edge of the sub-board containing the primary microphone. Carefully lift the board out of the phone frame.

13. 13

    Install the new microphone sub-board

    2 min

    Align the replacement microphone sub-board into its frame recess. Press gently until it sits flat inside the chassis.

14. 14

    Reconnect the antenna and flex cables

    2 min

    Snap the coaxial antenna cable connector onto its peg on the new board, then press the main interconnect flex cable connector straight down into place.

15. 15

    Secure the lower speaker module

    2 min

    Position the lower speaker housing over the sub-board and reinsert the securing Phillips #000 screws until snug.

16. 16

    Reconnect the battery and seal the back cover

    4 min

    Reattach the battery connector, reinsert the upper shield, apply fresh adhesive along the frame edge, and press the back cover firmly into place.
