In the following steps you will be cutting through the adhesive around the edge of the display assembly.

Refer to the second and third images and familiarize yourself with the width of the adhesive around edges of the display.

If you plan to re-use the display assembly, be particularly careful as you cut the adhesive on the sides of the phone. Don't insert your tool more than 2 mm into the phone, and angle it down (away from the display assembly) as much as possible.
