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 back cover with the suction handle to create a small gap between the back cover 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 pick 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 Xiaomi Mi 11 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.

There's lots of adhesive around the camera module so you'll need to heat here too.

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 screws securing the connector metal bracket and the camera cover:
Two 4.4 mm-long screws
One 4.9 mm-long screw
Two 3.9 mm-long screws

Schritt 9

Use a pair of tweezers to remove the connector bracket by pulling it in the direction of the battery.

Schritt 10

Use the pointed end of a spudger to disconnect the flash assembly cable by prying the connector straight up from its socket.

Schritt 11

The battery of the Xiaomi Mi 11 has two separate flex cables. You need to disconnect both in order to disconnect the battery completely.
Use a spudger to disconnect the right battery cable by prying the connector straight up from its socket.

Schritt 12

Use your fingers or a pair of tweezers to carefully lift the camera cover including the flash assembly off the camera lenses and remove it.

Schritt 13

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

Schritt 14

Insert an opening pick underneath the bottom left edge of the motherboard cover.
Slide the opening pick along the left edge of the motherboard cover and pry it up.
