Use this guide to replace a cracked or broken screen on your Huawei P8 Lite (2017).
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 phone’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 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.
You’ll need replacement adhesive to reattach components when reassembling the device.

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 these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
Take your e-waste to an R2 or e-Stewards certified recycler.
