Introduction

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.

This guide replaces only the display while leaving the original frame and battery in place. Some replacement screens for this phone come pre-installed on a new frame (a.k.a. chassis), which requires following a very different procedure. Make sure you have the correct part before starting this guide.
