Einleitung

Use this guide to replace the Charging Board on your Xiaomi Redmi Note 11 Pro.

You’ll need replacement adhesive to reattach the rear glass when reassembling the device. Your device will function normally, but will most likely lose its IP (Ingress Protection) rating.

Precut Adhesive Card

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 back cover and the frame.
If you're having 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 for one to two minutes 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.
At this point, the rear glass should be separated from the frame. If there's still resistance around the edges of the glass, use an opening pick to separate any 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 back cover with pre-cut adhesive or double-sided adhesive tape. After installing the back cover, 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

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 edge of the phone.
Press directly into the hole to eject the SIM card tray.
Remove the SIM card tray.
If you accidentally inserted the SIM eject tool into a microphone hole, don't worry! You most likely didn't damage the microphone.

Schritt 9

Use a Phillips screwdriver to remove the seventeen 3.6 mm-long screws securing the midframe.

Schritt 10

The midframe of the Xiaomi Redmi Note 11 Pro is held in place by plastic clips.
Insert an opening pick between the midframe and front panel assembly on the bottom left edge of the phone where the SIM tray slot is located.

Very hard to do can't get it to work

Schritt 11

The plastic clips of the midframe are sitting in place tightly. Releasing them might require some force.
Slide the opening pick around the bottom left corner of the phone to release the plastic clips.

Schritt 12

Slide the opening pick along the left edge of the phone to release the plastic clips.

Schritt 13

Slide the opening pick around the top left corner and along the top edge of the phone to release the plastic clips.

Schritt 14

Slide the opening pick around the top right corner and along the right edge of the phone to release the remaining plastic clips.
Do not try to remove the midframe all the way yet. The midframe cable is still connected to the motherboard.

Schritt 15

Carefully swing open the midframe to the left like you would open the front cover of a book to get free access to its cable connector.
Place the midframe next to the left edge of the front panel assembly.

Schritt 16

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

Schritt 17

Remove the midframe.

Schritt 18

Use a spudger to disconnect the left and right battery cable by prying the connectors straight up from their socket.

Schritt 19

Use a Phillips screwdriver to remove the 3.6 mm-long screw securing the loudspeaker.

Schritt 20

The loudspeaker of the Xiaomi Redmi Note 11 Pro is held in place by plastic clips.
Insert an spudger underneath the right edge of the loudspeaker.
Use your spudger to pry up the loudspeaker.

Schritt 21

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

Schritt 22

Slide a pair of tweezers under the black coaxial cable until they're snug against the metal connector.
Disconnect the black coaxial cable by prying it straight up from the charging board.
Use your tweezers to carefully loosen the cable from its routing on the charging board and bend it to the side.
