Step-by-step

1. 1

   Eject the SIM card tray

   1 min

   Insert a SIM eject tool into the hole near the upper left edge of the phone to pop out the SIM tray. Remove the tray completely and place it aside.

2. 2

   Heat the rear panel

   2 min

   Apply a heat gun set to 80°C evenly around the perimeter of the back panel for two minutes to soften the internal adhesive.

3. 3

   Apply a suction cup to the back cover

   2 min

   Press a suction cup onto the lower portion of the back panel and pull upward to create a small gap near the edge.

4. 4

   Slice the back panel adhesive

   4 min

   Insert a plastic opening pick into the gap and slowly slide it along all four edges to release the rear cover.

5. 5

   Remove the rear panel

   1 min

   Lift the rear cover away from the chassis carefully to avoid damaging any internal sensors.

6. 6

   Unscrew the upper motherboard bracket

   3 min

   Remove the Phillips #00 screws securing the plastic protection bracket over the upper section of the device.

7. 7

   Detach the motherboard bracket

   2 min

   Use a spudger to gently pry up and remove the motherboard bracket from the top edge.

8. 8

   Disconnect the battery cable

   1 min

   Pry the battery press connector straight up off the logic board using a nylon spudger to cut power.

9. 9

   Disconnect the display flex cable

   1 min

   Use the point of a spudger to disconnect the display ribbon cable from its logic board socket.

10. 10

    Disconnect the interconnect cable and side buttons

    2 min

    Pop the main interconnect flex cable and the volume/power button press connectors off the board.

11. 11

    Unplug the antenna cables

    2 min

    Gently pry up the coaxial antenna connectors along the right edge of the board using precise tweezers.

12. 12

    Remove the logic board screws

    2 min

    Unscrew the Phillips #00 screws locking the logic board to the internal frame.

13. 13

    Remove the logic board

    2 min

    Pry up the lower edge of the logic board carefully and lift it out of the phone frame.

14. 14

    Solder damaged components on the board

    15 min

    Apply flux and use a soldering iron with desoldering braid to replace damaged micro-components on the logic board.

15. 15

    Reinstall the logic board into the frame

    2 min

    Set the logic board back into the chassis top-first, ensuring it sits flush against the frame.

16. 16

    Reconnect all flex cables and antennas

    3 min

    Snap the display cable, interconnect cable, side button flexes, and coaxial antennas securely back into place.

17. 17

    Reconnect the battery and reassemble the bracket

    3 min

    Attach the battery press connector, place the upper bracket over the board, and tighten all retaining screws.
