Step-by-step

1. 1

   Eject the SIM card tray

   1 min

   Insert a SIM eject tool or thin paperclip into the pinhole on the left edge of the phone. Press firmly until the tray pops out, then pull it out completely.

2. 2

   Heat the rear panel

   2 min

   Use a heat gun or hair dryer set to low heat along the edges of the back cover for two minutes. This softens the factory adhesive holding the cover in place.

3. 3

   Attach the suction cup

   1 min

   Press a suction cup firmly onto the lower third of the rear plastic cover. Pull up gently on the ring to create a small gap between the panel and the frame.

4. 4

   Slice through the rear adhesive

   3 min

   Insert a plastic pry pick into the gap created by the suction cup. Slide the pick around the perimeter to cut through the glue, taking care not to pry too deep.

5. 5

   Open the rear cover slightly

   1 min

   Gently swing open the rear panel from the right edge like a book. Do not pull it away completely yet, as the fingerprint sensor flex cable is still attached.

6. 6

   Disconnect the fingerprint sensor cable

   2 min

   Use a plastic spudger to pop the fingerprint sensor press connector straight up off the motherboard. Set the rear cover aside.

7. 7

   Unscrew the upper motherboard bracket

   3 min

   Remove the Phillips #000 screws securing the plastic motherboard bracket to the chassis. Keep track of each screw location.

8. 8

   Remove the upper motherboard bracket

   1 min

   Insert the flat end of a spudger under the motherboard shield and lift it off the board. Store the bracket in a clean area.

9. 9

   Disconnect the battery cable

   1 min

   Pry up the battery press connector from its socket on the motherboard using a plastic spudger to cut power.

10. 10

    Disconnect the power and volume button flex cable

    2 min

    Locate the power/volume ribbon connector on the right side of the motherboard and detach it with a spudger.

11. 11

    Peel off the damaged power button cable

    2 min

    Slide fine-tip tweezers underneath the power button flex cable stuck along the inner frame. Carefully peel the cable away from the aluminum chassis.

12. 12

    Position the new power button flex cable

    2 min

    Remove the adhesive backing from the replacement power button cable. Align the tactile switches into the cutouts on the side frame and press firmly.

13. 13

    Connect the new power button cable

    1 min

    Align the flex cable connector over its motherboard socket and press straight down until it clicks into place.

14. 14

    Reconnect the battery cable

    1 min

    Align the battery connector with its motherboard port and snap it down firmly.

15. 15

    Reinstall the upper motherboard bracket

    3 min

    Place the plastic bracket over the motherboard and tighten the Phillips #000 screws until snug.

16. 16

    Attach fingerprint sensor and seal rear cover

    3 min

    Reconnect the fingerprint flex cable to the motherboard. Apply new adhesive along the inner rim and press the rear cover down tightly.
