Poco X3 Pro Screen Replacement

Deformed frames can cause mounting issues and uneven pressure damage, so replace it with a new one if necessary.

Remove the battery due to its design obstructing display cable access.

If damaged, replace the battery; reusing it poses a safety hazard.

Discharge the battery below 25% before disassembling to prevent accidental puncture and potential fire/explosion.

Some replacement screens come pre-installed in new frames, requiring a different procedure. Ensure you have the correct part before proceeding.

Additional materials needed: replacement adhesive for reassembling components.

Step 1 | Heat the back cover

Prepare an iOpener and apply it to the back cover for at least two minutes.

The adhesive underneath should loosen during this time.
If needed, use a hair dryer, heat gun, or hot plate instead. Be cautious not to overheat the phone as it may cause heat damage to the display and internal battery.

Step 2 | Insert an opening pick

Secure a suction handle to the back cover's bottom edge, as close to the edge as possible.

If the back cover is cracked, use strong tape or superglue the suction handle in place and allow it to cure before proceeding.
Lift the back cover with the suction handle to create a small gap between the cover and frame.

If trouble creating a gap arises, apply more heat to further soften the adhesive, 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.

Slide it towards the bottom left corner, slicing the adhesive.
Leave the pick in place to stop the adhesive from reforming.

Step 4 | Slice the adhesive

Reheat the adhesive with your iOpener for 1-2 minutes if it becomes hard to cut.

Insert a new opening pick at the bottom left corner of your phone.
Slide this pick along the left edge, slicing the adhesive as you go.
Leave the pick in the top left corner to prevent resealing.

Step 5

Insert a fourth opening pick under the top left corner.

Slide it along the top edge to cut the adhesive.
Leave it in place at the top right corner to prevent resealing.

Step 6

Insert a fifth opening pick under the top right corner.

Slide it along the right edge of the back cover to slice the remaining adhesive.

Step 7 | Remove the back cover

Remove the back cover.

Clean the relevant areas with isopropyl alcohol (>90%) before applying new adhesive.
Secure the new back cover using pre-cut adhesive or double-sided tape.
Apply strong, steady pressure to your phone for several minutes after installing the back cover. A stack of heavy books can provide sufficient pressure.

Step 8 | Unscrew the motherboard cover screws

Remove the motherboard cover using a Phillips screwdriver (correct size) by unscrewing the eleven 3.9 mm-long screws.

Step 9 | Pry up the motherboard cover

Place the tip of an opening pick at the bottom right edge of the motherboard cover.
Slide the pick along the right edge, unhinging clips to lift it out.
Use the pick to pry up the top edge of the motherboard cover.

Step 10 | Remove the motherboard cover

Remove the motherboard cover.

Step 11 | Disconnect the battery cable

Remove the battery cable using a spudger, prying the connector straight up from its socket.

Step 12 | Disconnect the power and volume button flex cable

Careful: Damage to the flex cable can occur.

Disconnect the power and volume button flex cable using a spudger, prying straight up from its socket.
Fold the power and volume button flex cable to the side with tweezers or your fingers for better access to the battery.

Step 13 | Disconnect the interconnect cable

Do not fold the cable sharply as this can cause damage.

Use a spudger to pry the interconnect connector straight up from its socket.
Fold the interconnect flex cable towards the charging port for access to the battery pull tabs.
Temporarily stick cables with tape to your working surface to avoid accidental damage.

Step 14 | Peel off the battery pull-tabs

Avoid puncturing or bending the battery as it may leak chemicals or cause a thermal event.

Use blunt nose tweezers or your clean fingernail to carefully peel off the orange adhesive strip labeled with an A from the battery.
Similarly, use blunt nose tweezers or a clean fingernail to remove the orange adhesive strip labeled with a B from the battery.

Step 15 | Remove the battery

Grab both pull-tab ends labelled A and pull up on the orange adhesive strip to lift the battery.

Pull firmly, as some force may be required.
If stuck, apply a heated iOpener to loosen the adhesive underneath.
Peel off the battery from any remaining adhesive.
Remove the battery completely.

If reassembling, temporarily reconnect the battery to help with alignment and then disconnect once seated.

If replacing the adhesive sticker, remove the old one from the midframe and clean the area with isopropyl alcohol (>90%).
Let the alcohol dry before installing a new adhesive sticker.

Step 16 | Remove the battery adhesive sticker

Careful not to touch any electrical components.

Peel off the battery's adhesive sticker using a pair of tweezers or your fingers.
If stuck, apply heat to loosen it: use an iOpener for at least one minute or a heat gun carefully positioned on the screen.

Step 17 | Disconnect the display flex cable

Disconnect the display flex cable by prying its connector straight up from its socket using a spudger.

Careful not to damage the connector.

The display flex cable is attached with mild adhesive. Peel it off the midframe using tweezers or your fingers.

Step 18 | Loosen the display adhesive

Protect the rear camera lenses with a lint-free cloth during repair.

Apply a heated iOpener or heat gun to the screen for at least 2 minutes to loosen adhesive.
The protective adhesive is strong, so reapply heat as needed to access the display panel.

Avoid overheating with hair dryer, heat gun, or hot plate.

Step 19 | Insert an iFlex

Apply a suction cup to the bottom edge of the warm screen.

If severely cracked, cover with clear packing tape for suction cup adhesion or use strong tape instead.

As last resort, superglue the suction cup in place.

Lift the screen with the suction handle to create a small gap between the screen and frame.
Insert an iFlex into the gap between the midframe and the screen.

Step 20 | Insert an opening pick

Insert a pick above the iFlex.

Remove the iFlex.
Slide the pick to the bottom right corner of the screen to slice its adhesive.

Do not remove the pick, as this will cause the adhesive to reseal.

Step 21 | Slice the adhesive

Insert another opening pick into the screen and gently slide it to the bottom left corner.

Leave this additional opening pick in place to maintain access to the adhesive.

Step 22

Reheat the adhesive for 1-2 minutes using an iOpener or heat gun if it becomes hard to cut.

Insert a new opening pick underneath the bottom left corner of the screen.
Slide the opening pick along the left edge of the screen to slice the adhesive, leaving it in the top left corner.

Step 23

When slicing near the front facing camera, insert only the tip of the opening pick.

Risk of damage or smearing the camera if not done carefully.

Insert a fourth opening pick at the top left corner of the screen.
Slide the opening pick along the top edge to slice the adhesive.
Leave the pick in the top right corner of the screen to prevent resealing.

Step 24

Insert another opening pick along the right edge.

Slide it to cut any remaining adhesive.

Wait until the display cable is free before lifting the display.

Step 25 | Remove the screen

Thread the display flex cable through the gap in the midframe.

Remove the screen from the device.

Always use isopropyl alcohol (at least 90%) for cleaning, as it helps maintain adhesive integrity.

Apply new adhesive where necessary after ensuring all relevant areas are clean.

For pre-cut adhesive card reassembly, follow this guide's specified procedures carefully to avoid any issues.
