While you wait for the adhesive to soften, note the following:

There's adhesive securing the back cover around the perimeter of the frame.

The adhesive is strongest in the bottom right and top left corners.

Apply a suction handle to the back cover, as close to the center of the right edge as possible.

Pull up on the suction handle with strong, steady force to create a gap between the cover and the frame.

If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the [https://www.ifixit.com/Guide/iOpener+Heating/25705|iOpener|new_window=true] instructions to avoid overheating.

Insert an opening pick into the gap.

Slide the pick back and forth along the right edge to separate the adhesive.
