Fold the screen away from the body keeping in mind not to damage the flex cables.

Add your strips of adhesive tape to the frame and put put the screen onto the body (I have highlighted the placement areas in blue)

You will have to cut the tape in half for the sides of the screen. Using a razor blade and a metal ruler will give best results.

Follow the steps in reverse for reassembly and use a couple of drops of super glue to put the front speaker cover back on
