Step-by-step

1. 1

   Power off the device

   1 min

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

2. 2

   Remove the back cover

   2 min

   Insert a plastic opening tool into the notch at the bottom corner of the rear panel. Pry upward gently to release the clips and remove the cover.

3. 3

   Remove the battery

   1 min

   Use the notch at the bottom edge of the battery compartment to lift the battery out. Store the battery in a safe, cool place.

4. 4

   Remove SIM and microSD cards

   1 min

   Slide out any installed SIM card or microSD card from their respective slots. Set them aside so they are not damaged during repair.

5. 5

   Unscrew the midframe fasteners

   4 min

   Remove the 10 screws around the perimeter of the inner midframe using a screwdriver. Organize the screws so none are misplaced.

6. 6

   Unclip the plastic midframe

   3 min

   Insert a plastic opening tool into the seam between the outer bezel and midframe. Slide the tool around the perimeter to release all plastic retention snaps.

7. 7

   Lift away the midframe

   1 min

   Gently lift the plastic midframe off the phone body. Set the midframe aside to expose the underlying motherboard.

8. 8

   Disconnect the display flex cable

   2 min

   Use the flat end of a spudger to pry the display connector straight up from its socket on the motherboard. Take care not to damage the motherboard pads.

9. 9

   Disconnect the front camera

   2 min

   Pry up the front-facing camera press connector using a spudger. Carefully lift the camera out of its recess if it comes loose.

10. 10

    Disconnect the rear camera

    2 min

    Pry up the rear camera press connector from the top left area of the motherboard. Lift the camera module out of the chassis.

11. 11

    Remove motherboard retaining screws

    2 min

    Unscrew the single small screw holding the top section of the motherboard to the frame. Keep this screw separate from the midframe screws.

12. 12

    Remove the motherboard

    2 min

    Lift the motherboard out of the phone frame, starting from the top edge. Place it on an anti-static work surface.

13. 13

    Apply flux to the charging port

    2 min

    Apply a liberal drop of liquid solder flux across all five pin connections and four mounting legs of the micro-USB port. Flux facilitates quick, clean heat transfer.

14. 14

    Heat the damaged port joints

    4 min

    Set your hot air station to 350°C (662°F) and direct air continuously over the charging port solder points. Keep the nozzle moving to prevent scorching the circuit board.

15. 15

    Remove the micro-USB port

    2 min

    Gently lift the micro-USB port off the motherboard using tweezers once the solder melts completely. Do not force the port off if solder is still solid.

16. 16

    Clean old solder from pads

    4 min

    Apply fresh flux and run desoldering wick with your soldering iron over the pads to remove excess solder. Clean the area using a cotton swab dipped in isopropyl alcohol.

17. 17

    Tin motherboard solder pads

    3 min

    Apply a tiny amount of fresh solder to each pin contact pad on the motherboard using a fine soldering iron tip. Ensure pads are smooth and bright.

18. 18

    Position the new charging port

    3 min

    Align the replacement micro-USB port anchor legs with the mounting holes on the motherboard. Verify that all five rear pins touch their respective pads flatly.

19. 19

    Solder structural mounting legs

    4 min

    Solder the four side mounting legs of the micro-USB port to firmly anchor the connector to the board. Ensure the port sits perfectly flush against the PCB edge.

20. 20

    Solder the data and power pins

    5 min

    Touch each rear pin contact briefly with a clean soldering iron tip to flow solder onto the joint. Use minimal solder to avoid creating bridges between pins.

21. 21

    Inspect solder connections

    3 min

    Examine all five pin joints under a magnifying glass to check for solid connections and ensure no solder bridges exist between adjacent pins. Touch up if necessary.

22. 22

    Clean off remaining flux

    2 min

    Scrub the repaired area lightly with a cotton swab soaked in 91% isopropyl alcohol to remove burnt flux residue. Allow the board to air dry for one minute.

23. 23

    Reinstall the motherboard

    3 min

    Lower the motherboard into the display housing frame, positioning the bottom edge first. Align all screw holes and ensure flex cables remain on top.

24. 24

    Secure the motherboard screw

    2 min

    Replace and tighten the single retaining screw near the top edge of the motherboard using your screwdriver.

25. 25

    Reconnect flex cables and cameras

    3 min

    Align and press down on the rear camera, front camera, and display flex connectors until they snap into place on the motherboard.

26. 26

    Reattach the midframe

    4 min

    Place the plastic midframe over the phone assembly and press firmly around the edges until all clips engage. Secure it with the 10 midframe screws.

27. 27

    Reinsert cards and battery

    2 min

    Slide your SIM card and microSD card back into their slots. Insert the removable battery into the housing, ensuring gold contacts match up.

28. 28

    Snap on the rear cover

    2 min

    Position the back cover onto the phone and press down around all edges until the plastic snaps lock tightly in place.
