Overview
Step-by-step
- 1
Eject the SIM card tray
1 minInsert 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
Heat the rear cover edges
3 minUse 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
Attach a suction cup to the rear glass
2 minPress 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
Insert an opening pick under the back glass
2 minInsert 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
Slice through the rear adhesive
5 minSlide 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
Remove the rear glass cover
1 minCarefully lift the rear glass off the phone chassis once all perimeter adhesive is severed. Set the back panel on a clean, soft surface.
- 7
Unscrew the motherboard bracket and speaker module
4 minUse 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
Peel up the wireless charging assembly
2 minGently peel the wireless charging pad and NFC coil away from the battery and motherboard frame. Set the assembly aside.
- 9
Disconnect the battery flex cable
1 minUse 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
Remove the lower speaker housing
2 minInsert a plastic spudger beneath the lower speaker module and pry upward to remove it from the lower frame.
- 11
Disconnect the primary display flex cable
2 minPry 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
Disconnect the main interconnect cables
3 minUse 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
Heat the front screen assembly
3 minApply 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
Attach a suction cup to the front screen
2 minPlace 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
Slice the perimeter display adhesive
5 minInsert 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
Separate the screen from the phone frame
3 minLift 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
Clean adhesive residue off the frame
4 minScrape 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.

Apply new frame display adhesive
3 minPeel 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.

- 20
Press and align the replacement screen
2 minAlign 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
Reconnect the display and interconnect cables
3 minAlign 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
Reconnect the battery press connector
1 minAlign the battery cable connector over its motherboard socket and press down firmly to secure power. Make sure the connection sits fully flush.
