Xiaomi Redmi Note 8 Pro Screen Replacement

はじめに

Your Xiaomi Redmi Note 8’s display can crack or break because of drops or unsuitable operation. Use this guide to replace a broken screen on a Xiaomi Redmi Note 8 Pro smartphone.

This guide involves removing the back cover of the device, so you will need a replacement adhesive to reattach the back cover to the phone.

Before disassembling your device, be sure the battery is charged below 25%. If accidentally punctured or damaged, the battery can catch fire and/or explode; if discharged below 25%, the chances of fire/explosion is decreased.

Be sure to power off the smartphone before beginning this repair process.

手順3

Use a heat gun to lightly heat the edges of the back to soften the adhesive that connects the back cover to the rest of the frame.
An iFixit iOpener, hair dryer, or hot plate can also be used to heat the edges. Using a heat gun, hair dryer, or hot plate will make the metal frame rather hot to the touch, so handle it with care.
Be careful not to overheat the device –the OLED display, battery and other internal parts can be damaged by excessive heat. Approximately one minute should be enough to soften the adhesive.
