Xiaomi Redmi Note 8 Screen Replacement
Never attempt to repair or replace the screen without proper precautions: discharge battery below 25% and verify correct part compatibility.
- Xiaomi Redmi Note 8 screen removal/ replacement requires a discharged battery (< 25%).
- Verify that your replacement screen is designed for the original frame, not a new chassis.
- Purchase correct replacement adhesives for both back panel and screen.
Step 1 | Heat the rear glass
Prepare an iOpener by applying it to the rear glass for at least two minutes to loosen the adhesive underneath.
- Alternatively, use a hair dryer, heat gun, or hot plate.
- Be cautious not to overheat the phone as the display and internal battery may be damaged by excessive heat.
Step 2 | Insert an opening pick
Secure a suction handle to the bottom edge of the rear glass, as close as possible.
If the rear glass is cracked, the suction handle may not stick; try lifting it with strong tape or apply superglue and allow it to cure.
- Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.
- Apply more heat if needed, following iOpener instructions to avoid overheating.
Insert an opening pick into the created gap.
Slide the opening pick to the bottom right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.
Step 3 | Slice the adhesive
Insert the second opening pick at the bottom edge of your phone.
- Slide the opening pick to the bottom left corner to cut the adhesive.
- Leave both opening picks in place to prevent resealing of the adhesive.
Step 4 | Slice the adhesive
Reheat the iOpener for one to two minutes if the adhesive becomes hard to cut.
- Insert a third opening pick at the bottom left corner of your phone.
- Slide the opening pick along the left edge to slice the adhesive.
- Leave the opening pick in the top left corner to prevent resealing.
Step 5
Position a fourth opening pick at the top left corner of your device.
- Slide it along the top edge to separate the adhesive.
- Leave the pick in place at the top right corner, preventing resealing.
Step 6
Insert a pick under the top right corner.
- Slide the pick along the right edge of the rear glass to cut remaining adhesive.
Do not remove the rear glass completely yet, as the camera cover and fingerprint assembly are still attached.
Step 7 | Open your phone
Avoid straining the fingerprint cable.
- Fold the rear glass to the right side, as if opening a book.
Step 8 | Disconnect the fingerprint reader
Disconnect the fingerprint reader using a spudger, lifting the connector upwards.
- Remove the rear glass assembly.
Step 9 | Unfasten the motherboard cover screws
Remove the motherboard cover using a screwdriver.
- Remove ten Phillips screws, each 3.9 mm long.
- Remove one additional Phillips screw, 3.4 mm long.
Step 10 | Pry up the motherboard cover
- Insert the tip of an opening pick under the bottom left edge of the motherboard cover.
- Ensure not to insert deeper than 3-4 mm to avoid damaging the motherboard.
Do not push the opening pick deeper — risk of damage.
- Slide the opening pick along the left edge to release the plastic clips and lift the cover.
Step 11
Insert the opening pick under the bottom right edge of the motherboard cover.
- Slide the opening pick along the right edge, unhinging the plastic clips.
- Pry the cover up from its original position.
Step 12 | Remove the motherboard cover
Remove the motherboard cover.
Step 13 | Disconnect the battery
Disconnect the battery cable with a spudger, prying the connector straight up from its socket.
Step 14 | Disconnect the display flex cable
Disconnect the display flex cable by using a spudger to pry the connector straight up from its socket.
Step 15 | Unfasten the daughterboard cover screws
Remove the daughterboard cover using a Phillips screwdriver.
- There are seven screws to remove, each 3.9 mm long.
Step 16 | Pry up the daughterboard cover
- Insert a opening pick with a tip around 3-4 mm under the top right edge of the daughterboard cover.
- Pry upwards on the opening pick to loosen the daughterboard cover and loudspeaker.
Step 17 | Remove the daughterboard cover
Remove the daughterboard cover and loudspeaker assembly.
Step 18 | Loosen the display adhesive
Apply iOpener to screen for 2+ minutes or use heat gun to soften adhesive.
Step 19 | Insert an opening pick
Apply a suction cup to the phone's bottom edge when it's warm to touch.
- If the screen is badly cracked, cover it with clear packing tape for better adhesion.
- Alternatively, use strong tape instead of a suction cup or apply superglue for extra hold.
Lift the screen using the suction handle to create a small gap between the screen and midframe.
- Insert an opening pick into the gap, taking care not to damage any cables.
If only replacing the display glass, be extremely careful as the LCD cable is fragile at the bottom right end. Use only the tip of your opening pick (1-2 mm).
- Slide the opening pick to the bottom right corner to slice the screen's adhesive.
- Leave the opening pick in place to prevent resealing of the adhesive.
Step 20 | Slice the adhesive
- Insert a second opening pick at the bottom left corner of the screen.
- Slide it downwards to cut the adhesive.
Leave the opening picks in place to prevent resealing of the adhesive.
Step 21
If the adhesive becomes hard to cut, it may have cooled down.
- Reheat the adhesive using a iOpener or heat gun for 1-2 minutes.
- Insert an opening pick underneath the bottom left corner of the screen.
- Slide the pick along the left edge to slice the adhesive, leaving it in the top left corner to prevent resealing.
Step 22
When slicing near the front-facing camera, use only the tip (about 3-4 mm) of the opening pick to avoid damaging or smearing the camera.
- Insert a fourth opening pick at the top left corner of the screen.
- Slide this pick along the top edge of the phone to slice the adhesive.
- Leave it in place at the top right corner to prevent resealing.
Step 23
Insert a fifth opening pick along the right edge of the phone to cut remaining adhesive.
Do not attempt to fully separate the display at this time; the display cable remains intact within the frame.
Step 24 | Remove the screen
Thread the display flex cable through the gap in the midframe.
- Remove the screen.
- Compare your new replacement part to the original part, transferring remaining components like the speaker grill if necessary.
Apply new adhesive only after cleaning relevant areas with isopropyl alcohol (>90%).
- If using a pre-cut adhesive card, refer to this guide during reassembly.
