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

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.

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.

Note: In this guide we’re using a teardown device. This means that the motherboard has been deshielded during the teardown procedure. You can still do all the repairs with this guide but your motherboard will look like this.

  1. Mi 11 Screen Replacement, Heat the rear glass: 手順 1、 1の画像 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.

  2. Mi 11 Screen Replacement, Insert an opening pick: 手順 2、 3の画像 1 Mi 11 Screen Replacement, Insert an opening pick: 手順 2、 3の画像 2 Mi 11 Screen Replacement, Insert an opening pick: 手順 2、 3の画像 3
    • 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.

終わりに

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.

Repair didn’t go as planned? Try some basic troubleshooting, or ask our Answers community for help.
