    • Lift the spudger gently to separate the back cover of the phone and the body of the phone.

    • Remove the eight screws in the body of the phone using the T4 Torx screwdriver.

    If the screw heads are stripped place a rubber band on the head, press down firmly with screwdriver tip and turn counter-clockwise to remove. Factory puts a drop of threadlock on some of the screws so a little extra force might be required to break screw free.

    • Gently take the power/volume switches off using a pair of needle nose pliers. Once removed, gently clean the solder that was there. Replace the solder with a new coat of solder.

    • Check out iFixit's soldering guides, here.

    With my phone the switches themselves don't fail. It's the solder connection that breaks. Once re-soldered I put a drop of UV-activated glue behind the switch to prevent it from moving too far when pressed.
