Step-by-step

  1. 1

    Eject the SIM tray

    1 min

    Insert a SIM eject tool into the hole on the left edge of the phone to pop out the SIM tray. Remove the tray and place it in a safe spot.

  2. 2

    Heat the back glass

    3 min

    Apply heat evenly across the rear panel using a heat gun set to low for two minutes to soften the perimeter adhesive. Do not concentrate heat in one spot for too long.

  3. 3

    Attach the suction cup

    2 min

    Place a suction cup onto the lower portion of the rear glass cover and press firmly to seal. Pull upward on the ring to create a slight gap between the glass and the body.

  4. 4

    Slice the rear adhesive

    5 min

    Insert a plastic opening pick into the gap created beneath the glass. Slide the pick along all four edges of the device to cut through the adhesive seal.

  5. 5

    Remove the rear glass

    2 min

    Gently lift the back cover completely off the chassis and set it aside. Use isopropyl alcohol and a microfiber cloth to clean residual tape off the frame.

  6. 6

    Unscrew the top frame cover

    3 min

    Remove the screws securing the top plastic cover and wireless charging bracket using your precision screwdriver. Organize the screws by size to ensure correct reassembly.

  7. 7

    Detach the wireless charging coil

    3 min

    Use the flat end of a spudger to pop the wireless charging connector straight off the board. Lift and remove the wireless coil and bracket assembly.

  8. 8

    Disconnect the battery flex

    2 min

    Pry the battery connector directly up off the motherboard using a spudger. This cuts power to the board and prevents electrical damage during repairs.

  9. 9

    Disconnect the rear camera assembly

    3 min

    Disconnect the two rear camera press connectors from the top right of the logic board. Pry up the camera module with tweezers and set it aside.

  10. 10

    Disconnect the front camera and Soli sensor

    3 min

    Unplug the front-facing camera, speaker, and Soli radar flex cables located near the top edge of the board. Take care not to tear the fragile ribbon cables.

  11. 11

    Disconnect the display and USB board flexes

    3 min

    Pop the display ribbon cable and lower daughterboard interconnect flex cable off their board sockets using a spudger. Ensure no flex cables cover the board edges.

  12. 12

    Remove the motherboard mounting screws

    3 min

    Unscrew the remaining retaining screws holding the motherboard to the phone chassis. Place the screws in a organizer tray to keep them separated.

  13. 13

    Extract the logic board

    3 min

    Insert a spudger under the bottom edge of the motherboard containing the Titan M security chip and lift it out of the chassis. Avoid flexing the board as you remove it.

  14. 14

    Seat the replacement motherboard

    3 min

    Position the new motherboard into the chassis, making sure all underlying ribbon cables remain accessible and un-trapped underneath the board.

  15. 15

    Reconnect all sensor and display flex cables

    4 min

    Align and press down on the display, lower board, camera, and Soli sensor press connectors until they snap firmly into place.

  16. 16

    Reconnect the battery cable

    2 min

    Press the battery cable connector onto its motherboard terminal until it snaps into position. Ensure the connection sits flat.

  17. 17

    Fasten the upper bracket screws

    3 min

    Place the wireless charging coil assembly back over the motherboard and line up the screw holes. Tighten the retaining screws until snug.

  18. 18

    Adhere the rear glass panel

    4 min

    Apply a fresh pre-cut adhesive strip around the frame border. Align the rear glass panel over the frame and press firmly around all edges to seal.
