Step-by-step

1. 1

   Power off the phone

   1 min

   Press and hold the power button, then tap Power Off on the screen. Ensure the device is completely shut down before proceeding.

2. 2

   Eject the SIM tray

   1 min

   Insert a SIM ejector tool into the pinhole on the upper left edge of the phone. Push firmly until the tray pops out, then remove it completely.

3. 3

   Warm the back cover

   2 min

   Apply heat evenly around the outer edges of the rear panel for two minutes using a heat gun. This softens the perimeter adhesive.

4. 4

   Attach the suction cup

   2 min

   Place a suction cup near the bottom edge of the rear panel. Pull upward steadily to create a slight gap between the cover and the chassis frame.

5. 5

   Insert a plastic opening pick

   2 min

   Slide a thin plastic pick into the seam created by the suction cup. Slice carefully along the bottom edge to cut through the adhesive seal.

6. 6

   Slice perimeter adhesive

   3 min

   Slide the pick around all four edges of the back cover. Keep the pick shallow near the side buttons to avoid damaging internal ribbons.

7. 7

   Remove the back cover

   1 min

   Lift the plastic back panel off the phone body once all adhesive is cut. Set the back panel aside on your clean workspace.

8. 8

   Unscrew the upper motherboard cover

   3 min

   Use a Phillips #000 screwdriver to remove all visible screws securing the plastic motherboard shield.

9. 9

   Detach the motherboard cover

   2 min

   Pry up the edges of the plastic motherboard shield using a spudger. Lift and remove the cover from the chassis.

10. 10

    Disconnect the battery cable

    1 min

    Use the flat end of a plastic spudger to pry the battery connector straight up from its motherboard socket. This prevents short circuits during repair.

11. 11

    Disconnect the power button flex cable

    2 min

    Locate the power button and fingerprint sensor connector on the motherboard. Use a spudger to gently pop the flex cable press-connector off its socket.

12. 12

    Pry up the power button metal bracket

    2 min

    Use tweezers to lift and remove the small metal retaining clip securing the power button mechanism inside the side housing frame.

13. 13

    Remove the damaged power button assembly

    2 min

    Carefully peel the power button flex cable away from the interior side frame using fine-tip tweezers, then extract the button key assembly.

14. 14

    Install the new power button flex cable

    3 min

    Position the new power button ribbon inside the side frame slot. Press the self-adhesive backing firmly against the metal wall and reinstall the metal bracket.

15. 15

    Connect the new flex cable

    1 min

    Align the power button press-fit connector directly over its motherboard socket and press down firmly until it snaps into place.

16. 16

    Reconnect the battery

    1 min

    Align the battery flex connector over its terminal and press down until it securely clicks into place.

17. 17

    Reinstall the motherboard cover

    3 min

    Position the plastic motherboard shield over the top portion of the phone. Secure it by reinserting and tightening all Phillips screws.

18. 18

    Reseal and attach the back cover

    3 min

    Apply fresh pre-cut adhesive tape along the frame perimeter. Press the back cover down firmly along all edges to complete assembly.
