Place your fingers on either side of the phone and gently push up on the rear case.
It is important to start from the bottom of the phone because the rear case wraps around the front of the phone at the top which makes it impossible to start prying from there.
Using a soldering iron set at 400 degrees Celsius (752 degrees Fahrenheit), heat the solder joints lateral to the USB port. Use a pair of tweezers to lift the port from the board.
Extreme caution should be taken when working with high-temperature equipment to reduce the chance of burns.
Care should be taken while desoldering the joints as the heat could melt the plastic casing on the port. It is strongly recommended that soldering surface-mounted components guide is referenced before proceeding.
