Use this guide to remove the screen of the Huawei Honor 9.

Before disassembling your phone, 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.

This guide involves removing the rear glass cover and the battery—you will need replacement adhesive to reattach both and/or a new battery. If your replacement part does not come with adhesive, use a strong double-sided tape to secure it.

  1. Switch off your phone.
    • Switch off your phone.

    • Heat an iOpener and apply it to the back of the phone for around two minutes. This will help soften the adhesive securing the rear glass.

    • You might need to reheat and reapply the iOpener several times during the rear glass removal.

    • 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. Secure a suction handle to the lower edge of the rear glass, as close to the edge as possible. If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Lift the rear glass with the suction cup to create a gap between the glass and the frame.

    • Insert an opening pick into the gap.

    • If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

  3. Slide the opening pick to the bottom right corner. Insert a second opening pick and slide it to the bottom left corner. Leave the opening picks in place to prevent the adhesive from resealing.

  12. Apply an iOpener to the center of the display, to loosen the adhesive beneath the battery. The adhesive beneath the battery is very strong. You might need to repeat this process during the removal procedure several times. If heat does not work you can apply isopropyl alcohol (90+%) to the corners of the battery and let it penetrate the adhesive for several minutes before continuing. The flex cables under the battery are laid out as seen in the image. Try  to avoid prying in the marked areas to prevent damaging the cables.
