Introduction

Rather than buying a new phone because it will no longer charge, you can use this guide to replace the charging port. Please be sure to use caution when working with the soldering iron, as it can get very hot.

  • Power off your Phone before beginning disassembly.
  • Use the ‘Jimmy’ and ‘Metal Spudger’ to slowly pry open the outsides of the back case.
