Einleitung

Use this guide to remove or replace the screen on your Xiaomi Mi 11 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.

Before you begin this procedure, be sure to have a set of replacement adhesives for both the back panel and the screen.

Werkzeuge

Ersatzteile

Schritt 1

Insert a SIM card eject tool, a SIM eject bit, or a straightened paper clip into the hole on the SIM card tray located on the left edge of the phone.
Be careful not to insert the eject tool into the opening of the microphone next to the USB-C port.
Press directly into the hole to eject the SIM card tray.
Remove the SIM card tray.

Schritt 2

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 3

Secure a suction handle to the right 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.
If 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 top right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

Schritt 4

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

Schritt 5

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

Schritt 6

Insert a fourth opening pick underneath 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 the adhesive from resealing.

Schritt 7

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

Schritt 8

Remove the rear glass.
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 9

Use a Phillips screwdriver to remove the eleven 3.4 mm-long screws securing the motherboard cover.

Schritt 10

Insert the tip of an opening pick underneath the left edge of the motherboard cover.
Use the opening pick to pry up the motherboard cover.
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 the flat end of a spudger to disconnect the SIM card tray cable from the motherboard.

Schritt 13

Use a Phillips screwdriver to remove the four screws securing the SIM card tray in the midframe:
Three 3.5 mm screws
One 3.0 mm screw

Schritt 14

Use a pair of blunt nose tweezers to remove the SIM card tray from the phone assembly.

Schritt 15

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

Schritt 16

Apply a heated iOpener or a heat gun to the screen for two minutes to loosen the adhesive underneath.

Schritt 17

Once the screen is warm to the touch, apply a suction cup to the right edge of the phone.
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 cup. 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 opening pick into the gap between the midframe and the screen.

Schritt 18

Slide the opening pick to the top right corner of the screen to slice its adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

Schritt 19

Insert a second opening pick underneath the top right corner.
Slide the opening pick to the bottom right corner of the screen to cut the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Schritt 20

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 right corner of the screen.
Slide the opening pick along the bottom edge of the screen to slice the adhesive.
Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.

Schritt 21

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

Schritt 22

Insert a fifth opening pick underneath the top left corner.
Slide the opening pick along the top 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 23

Use the flat end of a spudger to carefully pry up the display connector from the midframe.

Schritt 24

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

Schritt 25

Remove the screen.
Apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
During reassembly, follow this guide if 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.

Take your e-waste to an R2 or e-Stewards certified recycler.

Beim Kauf eines neue Displays unbedingt darauf achten, welche Modellnummer ihr habt! Hier gibt es augenscheinlich unzählige verschiedene Varianten!
Habe mein Display bei ALIExpress gekauft und gut die Hälfte gegenüber dem deutschen Verkauf (wo mein benötigtes Modell zudem gar nicht verfügbar war) gespart!
Hier gäbe es das Display mit Modellnummer 2109119DG 2107119DC 2109119DI: KLICK
