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.
