Einleitung

Use this guide to replace a cracked or broken screen on your Xiaomi Mi 10 Lite.

If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.

Before disassembling your device, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

Note: This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.

You’ll need replacement adhesive to reattach components when reassembling the device.

Ersatzteile

Schritt 1

Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

Schritt 2

Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.
If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.
In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Insert an opening pick into the gap you created.
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.

Schritt 3

Insert a second opening pick at the bottom edge of your phone.
Slide the opening pick to the bottom left corner to slice the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Schritt 4

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener to reheat it.
Insert a third opening pick at the bottom left corner of your phone.
Slide the opening pick along the left edge of your phone to slice the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Schritt 5

Insert a fourth opening pick underneath the top left corner of your phone.
Slide the opening pick along the top edge to slice the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Schritt 6

Insert a fifth opening pick underneath the top right corner.
Slide the opening pick along the right edge of the rear glass to slice the remaining adhesive.

Schritt 7

Remove the rear glass.
Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

Schritt 8

Use a Phillips screwdriver to remove the ten 3.9 mm-long screws securing the motherboard cover.

Schritt 9

Insert the tip of an opening pick underneath the right edge of the motherboard cover.
Slide the opening pick to the top right corner of the motherboard cover to unhinge the plastic clips and pry it up.

Schritt 10

Use a pair of tweezers or your fingers to remove the motherboard cover.

Schritt 11

Use a spudger to disconnect the battery cable by prying the connector straight up from its socket.

Schritt 12

Use a spudger to disconnect the interconnect flex cable by prying the connector straight up from its socket.

Schritt 13

Insert a SIM card eject tool, a SIM eject bit, or a straightened paper clip into the hole on the SIM tray located at the bottom right edge of the phone.
Press directly into the hole to eject the SIM card tray.
Remove the SIM card tray.

Schritt 14

Use a Phillips screwdriver to remove the seven 3.9 mm-long screws securing the loudspeaker assembly.

Schritt 15

Insert an opening pick underneath the top right corner of the loudspeaker assembly and pry it up.

Schritt 16

Remove the loudspeaker assembly.

Schritt 17

Use a spudger to disconnect the bottom left connector of the interconnect flex cable by prying the connector straight up from its socket.

Schritt 18

Use a spudger to disconnect the bottom right connector of the interconnect flex cable by prying the connector straight up from its socket.
Remove the interconnect cable.

Schritt 19

Use a pair of tweezers to carefully disconnect the white coax cable from the daughterboard.
Use your pair of tweezers to carefully free the white coax cable from its routing on the daughterboard and fold it to the side.

Schritt 20

Use a spudger to disconnect the fingerprint sensor cable by prying the connector straight up from its socket.
Use your spudger to carefully fold the fingerprint sensor cable to the side to get free access to the daughterboard.

Schritt 21

Insert an opening pick into the gap between the top edge of the daughterboard and the antenna cables.
Use your opening pick to pry up the daughterboard.

Schritt 22

Don't try to remove the daughterboard by pulling it straight upwards. The USB-C connector is blocked by the midframe of the phone.
Use a pair of blunt nose tweezers or your fingers to remove the daughterboard by pulling it in a flat angle in the direction of the battery.

Schritt 23

Use a spudger to disconnect the display flex cable by prying the connector straight up from its socket.

Schritt 24

Apply a heated iOpener or a heat gun to the screen to loosen the adhesive underneath. Apply the iOpener for at least two minutes.
The protective adhesive of the Xiaomi Mi 10 Lite is very strong and it's hard to get underneath the display panel in the beginning. It is likely that you have to reapply the iOpener more than once.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.

Schritt 25

Once the screen is warm to touch, apply a suction handle to the bottom edge of the screen.
If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction cup to the screen.
Lift the screen with the suction handle to create a small gap between the screen and the frame.
Insert an iFlex into the gap between the midframe and the screen.

Schritt 26

Insert an opening pick above the iFlex.
Slide the opening pick to the bottom right corner of the screen to slice its adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

Schritt 27

Remove the iFlex.
Insert a second opening pick at the bottom edge and slide it to the bottom left corner of the screen to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

Schritt 28

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener or heat gun for 1-2 minutes to reheat it.
Insert a third 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.
Leave it in the top left corner to prevent the adhesive from resealing.

Schritt 29

When you slice near the front facing camera, insert only the tip of the opening pick (about 2-3 mm) to avoid damaging or smearing the camera.
Insert a fourth opening pick at the top left corner of the screen.
Slide the opening pick along the top edge of the phone to slice the adhesive.

Schritt 30

Insert a fifth opening pick and slide it along the right edge of the phone to slice the remaining adhesive.
Do not try to remove the display all the way yet, the display cable is still threaded through the frame.

Schritt 31

Thread the display flex cable through the gap in the midframe and remove the screen.
Compare your new replacement part to the original part—you may need to transfer remaining components from your old screen to your replacement part.
Apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
During reassembly, follow this guide in case you're using a pre-cut adhesive card.

Abschluss

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen.
