简介
Use this guide to remove or replace the daughterboard in your Motorola Edge 5G UW (2022).
Before you begin, download the Rescue and Smart Assistant app to backup your device and diagnose whether your problem is software or hardware related.
For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
The daughterboard and USB-C charging port are soldered together; replacing one component means replacing both.
You'll need replacement adhesive to complete this repair.
