Step-by-step

1. 1

   Power down the device

   1 min

   Press and hold the power button, then select Power Off to shut down the phone completely. Unplug any connected cables before starting.

2. 2

   Eject the SIM tray

   1 min

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

3. 3

   Heat the rear panel

   2 min

   Use a heat gun on low power or a hair dryer to warm the perimeter of the rear cover for two minutes. This softens the adhesive holding the plastic back panel.

4. 4

   Apply suction cup

   1 min

   Press a suction cup firmly onto the lower third of the back cover near the charging port. Pull up on the handle gently to create a small gap between panel and frame.

5. 5

   Insert an opening pick

   2 min

   Slide a thin plastic opening pick into the gap created beneath the back cover edge. Leave the pick in place to prevent the adhesive from re-adhering.

6. 6

   Slice perimeter adhesive

   3 min

   Slide plastic prying tools around all four edges of the back cover to slice through the adhesive layer. Apply extra heat if the pick meets strong resistance.

7. 7

   Remove the back cover

   2 min

   Lift the rear cover away from the chassis and set it on your work mat. Use a spudger to scrape away large remnants of old adhesive from the inner frame.

8. 8

   Unscrew lower speaker housing

   2 min

   Use a Phillips #000 screwdriver to remove the screws securing the lower speaker assembly over the sub-board. Organize the screws in a tray for reassembly.

9. 9

   Remove speaker housing

   2 min

   Insert a plastic spudger beneath the edge of the lower speaker module and pry upward to release it. Remove the housing to gain access to the charging port sub-board.

10. 10

    Disconnect main flex cable

    1 min

    Use the flat edge of a spudger to pop the main interconnect flex connector straight up from the sub-board. Bend the cable back slightly to keep it out of the way.

11. 11

    Disconnect coaxial antenna

    2 min

    Gently pry the white coaxial antenna cable connector off its terminal on the sub-board using fine tweezers. Pry underneath the metal head rather than pulling the wire.

12. 12

    Remove sub-board retaining screw

    1 min

    Unscrew the single Phillips screw securing the charging port sub-board to the inner frame. Place the screw alongside your speaker cover hardware.

13. 13

    Pry up the sub-board

    2 min

    Slide a plastic opening tool under the front edge of the sub-board and carefully lift it out of its chassis recess. Transfer the board to your soldering work area.

14. 14

    Desolder defective USB-C port

    5 min

    Apply liquid flux to the charging port anchor pins and rear data pads. Heat the joints using a soldering iron and desoldering braid to wick away old solder, then lift off the port.

15. 15

    Solder replacement USB-C port

    5 min

    Position the new USB-C port onto the sub-board pads. Apply a small amount of flux and solder each anchor leg and data pin securely, ensuring no solder bridges form.

16. 16

    Seat repaired sub-board

    2 min

    Place the sub-board back into its recess inside the lower chassis. Press down lightly until it aligns flush against the frame alignment pins.

17. 17

    Secure sub-board screw

    1 min

    Reinstall and tighten the single Phillips screw that holds the sub-board to the frame. Ensure the board remains flat during tightening.

18. 18

    Reconnect cables

    2 min

    Snap the main flex cable connector down onto the sub-board terminal until it clicks. Use tweezers to push the coaxial antenna cable head back onto its socket.

19. 19

    Reinstall speaker housing

    2 min

    Align the lower speaker housing over the sub-board assembly and press down until it snaps into place. Fasten all Phillips screws to secure it.

20. 20

    Reattach rear panel

    3 min

    Apply a thin bead of B-7000 adhesive along the frame edge perimeter. Align the back cover onto the phone and press down firmly around all edges to seal.
