Step-by-step

1. 1

   Eject the SIM tray

   1 min

   Insert a SIM eject tool into the pinhole beside the card tray on the left frame. Press firmly to pop out the tray and pull it completely out.

2. 2

   Heat the back panel

   2 min

   Apply a heat gun or iOpener around the outer edges of the back cover for two minutes to soften the perimeter adhesive.

3. 3

   Slice the rear adhesive

   3 min

   Insert a plastic opening pick under the edge of the back panel. Gently slide it around all four edges to cut through the adhesive seal.

4. 4

   Remove the back cover

   1 min

   Carefully lift the rear panel straight up and remove it from the phone. Set it aside on a clean surface.

5. 5

   Unscrew the upper motherboard bracket

   2 min

   Use a Phillips #00 screwdriver to remove the screws securing the plastic motherboard frame and camera surround.

6. 6

   Detach the upper frame cover

   1 min

   Insert a spudger under the edge of the upper plastic cover. Pry gently to unclip and remove it.

7. 7

   Disconnect the battery cable

   1 min

   Pry the battery press connector straight up from its motherboard socket using a plastic spudger. Disconnecting power prevents short circuits during board service.

8. 8

   Disconnect the display flex cable

   1 min

   Use the tip of a spudger to disconnect the display connector from the top right of the logic board.

9. 9

   Disconnect the main sub-board flex cable

   1 min

   Pry the lower interconnect flex cable connector off its press socket on the bottom portion of the logic board.

10. 10

    Disconnect the camera modules

    2 min

    Unplug the front-facing and rear camera press connectors from the board. Lift the cameras out of their recesses using fine tweezers.

11. 11

    Remove logic board retaining screws

    2 min

    Locate and remove any remaining Phillips screws fixing the logic board down to the phone frame.

12. 12

    Lift out the logic board

    2 min

    Pry carefully under the lower edge of the logic board with a spudger. Lift the board clear from the chassis.

13. 13

    Perform board repair

    15 min

    Apply rosin flux to the target joint on the logic board and use a fine tip soldering iron or heat flux station to perform necessary trace or SMD component repair.

14. 14

    Reseat the logic board

    2 min

    Position the repaired logic board back into the midframe, ensuring all underlying flex cables sit clear of the board alignment pins.

15. 15

    Reconnect camera and flex cables

    3 min

    Press the front camera, rear camera, display flex, sub-board flex, and battery connectors firmly into their sockets until they snap closed.

16. 16

    Reinstall the motherboard bracket

    2 min

    Align the upper plastic shield over the logic board and re-tighten all Phillips screws until snug.

17. 17

    Reseal the back cover

    3 min

    Clean remaining old adhesive with isopropyl alcohol, apply fresh cut adhesive strips to the edges, and press the rear cover firmly onto the chassis.
