Flip your phone over so the display is facing up.

Apply a suction handle to the middle of the display's left edge, as close to the edge as possible.

Place the tip of an opening pick in the small gap between the back cover and the display.

Pull up on the suction cup with a strong, steady force and push the opening pick down at a 45 degree angle until it slides into the gap between the back cover and the display.

If you're having a hard time inserting the pick, reheat the adhesive with an iOpener and try again.
