   1 min

   Slide out any installed micro-SIM and microSD cards from their respective slots. Store them in a safe place during repair.

4. 4

   Unscrew the inner midframe

   5 min

   Use a Torx T3 screwdriver to remove all 14 perimeter screws securing the inner midframe. Keep track of screw positions.

5. 5

   Pry up the midframe

   3 min

   Insert a plastic spudger between the midframe and display assembly. Gently work around the perimeter to release the plastic clips and lift off the midframe.

6. 6

   Disconnect the battery cable

   2 min

   Locate the battery flex connector near the top right of the motherboard. Use a plastic spudger to pry the connector straight up from its socket.

7. 7

   Disconnect the display flex cable

   2 min

   Locate the wide display ZIF connector on the motherboard. Flip up the locking lever and slide the ribbon cable out.

8. 8

   Disconnect the front camera flex cable

   2 min

   Use a plastic spudger to detach the front-facing camera connector. Carefully lift the camera module out of its housing.

9. 9

   Disconnect the rear camera flex cable

   2 min

   Pry up the rear camera press-fit connector using a spudger. Lift the rear camera module clear of the frame.

    Unscrew the motherboard

    2 min

    Remove the remaining Torx T3 screw holding the motherboard to the frame. Store the screw safely.

11. 11

    Remove the motherboard

    3 min

    Gently lift the motherboard from the bottom edge and remove it from the housing. Place it on an anti-static mat.

12. 12

    Apply flux to port pins

    2 min

    Apply a small amount of liquid soldering flux onto the charging port solder anchor points and rear data pins.

13. 13

    Desolder the micro-USB port

    6 min

    Heat the anchor legs and pins with a fine-tip soldering iron. Use fine tweezers to lift the damaged charging port clear off the board.

14. 14

    Clean the solder pads

    3 min

    Place desoldering wick over the motherboard pads and press down with the soldering iron to absorb residual solder. Clean the area with isopropyl alcohol.

15. 15

    Position the replacement port

    2 min

    Align the new micro-USB port through-hole legs into the motherboard mounting holes. Ensure all pins align perfectly with the pads.

    Solder the port anchor legs

    4 min

    Heat each anchor post with the soldering iron and feed a small amount of fresh solder to secure the port physically.

17. 17

    Solder the data and power pins

    5 min

    Carefully solder each of the tiny rear pins to its corresponding board pad. Avoid creating solder bridges between adjacent pins.

18. 18

    Inspect the solder connections

    2 min

    Examine the solder joints using a magnifying glass to confirm strong connection and zero short circuits between pins.

19. 19

    Reinstall the motherboard

    3 min

    Set the motherboard back into the phone frame, ensuring no flex cables get trapped underneath. Replace the single motherboard retaining screw.

20. 20

    Reconnect the camera modules

    3 min

    Reinsert the front and rear cameras into their sockets and press down on their flex connectors until they snap into place.

22. 22

    Reconnect the battery cable

    2 min

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

23. 23

    Reattach the inner midframe

    3 min

    Place the plastic inner midframe over the assembly and press down around the edges until all clips snap closed.

24. 24

    Tighten the midframe screws

    5 min

    Reinstall all 14 Torx T3 screws into the midframe in a crisscross pattern until snug.

25. 25
