Step 1.

Remove the sim card tray located on the side of the iPhone. Use a sim card removal tool or a small pin by pressing into the sim card tray hole. The sim card tray should slide out.


Step 2.

Remove the two screws located on the bottom of the iPhone.


Step 3.

Slide the back cover up and out to get access to the internal components.


Step 4.

Disconnect the battery by removing the screw holding the connection in place. Lift the connection out using the spudger tool. Once disconnected pry the iPhone battery out.


Step 5.

Remove the antenna connection cover and the antenna located next to the battery connection. It simply snaps off.


Step 6.

Remove two screws holding the metal plate covering the charging port flex cable. Once the plate is removed simply lift the connection from the motherboard.


Step 7.

Remove two screws holding the speakerphone in place. The screw on the left also holds the motherboard in place.

Pry the iPhone screen from the mid-frame and remove the two flex cables through the opening in the mid-frame.
