Step-by-step

  1. 1

    Eject the SIM card tray

    1 min

    Insert a SIM eject tool into the pinhole at the top of the phone to release the tray. Remove the SIM card tray completely from the device.

  2. 2

    Heat the rear cover edges

    3 min

    Use a heat gun on low power to warm the outer edges of the rear glass panel for 2 to 3 minutes. This softens the strong internal factory adhesive.

  3. 3

    Attach a suction cup to the rear glass

    2 min

    Press a suction cup firmly near the bottom edge of the rear glass panel. Pull up on the ring to create a small gap between the glass and the metal frame.

  4. 4

    Insert an opening pick under the back glass

    2 min

    Insert the tip of a plastic opening pick into the seam created by the suction cup. Do not insert the pick deeper than 3 mm to avoid damaging underlying flex cables.

  5. 5

    Slice through the rear adhesive

    5 min

    Slide the pick along the entire perimeter of the back glass to cut through the surrounding adhesive. Reapply heat with your heat gun if you encounter heavy resistance.

  6. 6

    Remove the rear glass cover

    1 min

    Carefully lift the rear glass off the phone chassis once all perimeter adhesive is severed. Set the back panel on a clean, soft surface.

  7. 7

    Unscrew the motherboard bracket and speaker module

    4 min

    Use a Phillips #00 screwdriver to remove all 15 screws securing the wireless charging coil and lower speaker cover. Keep the screws organized by location for reassembly.

  8. 8

    Peel up the wireless charging assembly

    2 min

    Gently peel the wireless charging pad and NFC coil away from the battery and motherboard frame. Set the assembly aside.

  9. 9

    Disconnect the battery flex cable

    1 min

    Use the flat end of a plastic spudger to pop the battery connector straight up off its motherboard socket. This prevents short circuits during the remainder of the repair.

  10. 10

    Remove the lower speaker housing

    2 min

    Insert a plastic spudger beneath the lower speaker module and pry upward to remove it from the lower frame.

  11. 11

    Disconnect the primary display flex cable

    2 min

    Pry up the display ribbon cable connector from the bottom corner of the motherboard using a spudger. Unclip the opposite end from the sub-board as well.

  12. 12

    Disconnect the main interconnect cables

    3 min

    Use a spudger to disconnect the ribbon cables bridging the mainboard to the daughterboard. Carefully unclip the small 5G antenna flex cables adjacent to the board.

  13. 13

    Heat the front screen assembly

    3 min

    Apply heat continuously across the front screen with a heat gun for 3 minutes to soften the display adhesive. Keep the heat source moving constantly to prevent glass or frame distortion.

  14. 14

    Attach a suction cup to the front screen

    2 min

    Place a suction cup onto the lower portion of the cracked screen and pull upward to create a small gap. Take care around heavily shattered areas.

  15. 15

    Slice the perimeter display adhesive

    5 min

    Insert a thin plastic pick into the gap between the glass and the bezel frame. Slide the pick around all four edges to slice through the adhesive layer.

  16. 16

    Separate the screen from the phone frame

    3 min

    Lift the damaged display off the frame while carefully guiding its flex cable through the frame slot. Ensure no loose glass fragments remain inside the inner phone cavity.

  17. 17

    Clean adhesive residue off the frame

    4 min

    Scrape away remaining adhesive strips using a plastic tool and clean the inner bezel with 99% isopropyl alcohol. A clean frame surface ensures proper adhesion for the new screen.

  18. 18

    Apply new frame display adhesive

    3 min

    Peel the protective backing off your pre-cut screen adhesive tape and press it firmly along the perimeter of the frame. Remove the top liner strip to expose the sticky surface.

  19. 19

    Thread the replacement screen cable

    2 min

    Feed the ribbon cable of the new display panel through the frame slot. Carefully lower the new screen panel onto the phone frame without pinching the cable.

  20. 20

    Press and align the replacement screen

    2 min

    Align the replacement display with the chassis borders and press down along the outer edges. Hold firm, steady pressure around the edges for 1 minute to set the adhesive seal.

  21. 21

    Reconnect the display and interconnect cables

    3 min

    Align and press the display flex connector onto its mainboard socket until it clicks. Reattach the main interconnect ribbon cables between the mainboard and daughterboard.

  22. 22

    Reconnect the battery press connector

    1 min

    Align the battery cable connector over its motherboard socket and press down firmly to secure power. Make sure the connection sits fully flush.

  23. 23

    Reinstall the lower speaker housing

    2 min

    Position the speaker assembly back into the lower frame cavity and press down until it sits completely flush.

  24. 24

    Reinstall the wireless charging pad and upper cover

    4 min

    Lay the wireless charging coil back onto the motherboard frame and align the screw holes. Insert and tighten the 15 Phillips #00 screws until secure.

  25. 25

    Apply back cover adhesive

    2 min

    Lay new pre-cut adhesive strips around the rear edge of the phone frame. Peel away the top protective film to expose the fresh adhesive.

  26. 26

    Seal the back cover

    2 min

    Align the rear glass cover accurately over the phone chassis and press firmly along all edges to complete the repair seal.
