Overview
Step-by-step
- 1
Power down the fold device
1 minPress and hold the Power and Volume Down buttons, then select 'Power Off' on the screen. Ensure the device is fully shut down before proceeding.
- 2
Heat the outer screen edges
2 minUse a heat gun on low heat for 2 minutes around the perimeter of the front outer display. Avoid overheating to prevent frame deformation.
- 3
Attach suction cup tool
2 minPlace a suction cup near the bottom edge of the outer screen assembly. Pull up gently on the ring to create a slight gap between the glass and bezel.
- 4
Insert opening pick
2 minInsert a thin plastic opening pick into the gap created between the outer glass and the bezel. Keep the pick inserted shallowly to protect internal components.
- 5
Slice bottom adhesive
3 minSlide the opening pick carefully along the bottom edge of the outer screen to cut through the adhesive layer. Leave the pick in place to prevent the adhesive from re-sealing.
- 6
Slice right edge adhesive
3 minInsert a second opening pick and slide it slowly along the right side of the outer display frame. Sever all sticky residue along the side rail.
- 7
Slice top edge adhesive
3 minMove an opening pick across the top edge of the screen assembly. Take extra care around the top earpiece speaker cutout.
- 8
Slice hinge side adhesive
3 minSlide the pick along the left hinge side of the display glass until the screen separates freely. Verify that all four sides are completely detached.
- 9
Lift the outer display
2 minGently swing the outer screen open from the right edge toward the hinge like a book cover. Do not pull the display away completely yet, as the ribbon cable is still attached.
- 10
Remove the connector bracket
2 minUse a Phillips #000 screwdriver to remove the single screw securing the metal display connector shield. Lift the bracket away with fine-tip tweezers.
- 11
Disconnect outer display flex cable
2 minPry the outer display press connector straight up from its socket on the motherboard using the flat end of a spudger. Remove the old outer screen.
- 12
Scrape off residual adhesive
4 minUse a plastic prying tool to scrape all old adhesive tape strips off the inner lip of the metal frame channel. Ensure no adhesive lumps remain.
- 13
Clean frame bezel surface
3 minDampen a lint-free microfiber cloth with 99% isopropyl alcohol and wipe down the display frame perimeter. Allow the metal surface to air-dry completely.
- 14
Apply new screen adhesive
4 minPeel the protective backing off the pre-cut adhesive gasket and place it precisely onto the cleaned frame rim. Press firm along all sides, then remove the top liner film.
- 15
Connect the new screen flex cable
2 minPosition the replacement outer display screen next to the phone and press its ribbon cable connector into the motherboard socket until it clicks. Avoid pressing on the center of the chip.
- 16
Reinstall the connector bracket
2 minSet the metal display cable bracket back over the connector. Secure it using the single Phillips #000 screw you removed earlier.
- 17
Seat the new outer screen
2 minCarefully align the new outer display screen assembly over the front frame recess. Lower it straight down, making sure the ribbon cable folds neatly inside.
- 18
Press edges to set adhesive
3 minApply firm, consistent pressure with your fingers around all four borders of the new display for 1 minute. Ensure the screen rests flush against the frame.
