Use this guide to remove or replace the screen on your Huawei P40 Pro.

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.

Due to the device’s design, you must remove the lithium-ion battery to access the display cables. If the battery was deformed during removal replace it with a new one—reusing a deformed battery is a potential safety hazard.

Before disassembling your device, ***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 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 replacement adhesives for the back panel, battery and the screen (depending on your replacement part you will need adhesive for the earpiece speaker module as well).
