Place an iFixit opening tool in the crease where the display assembly and back of the device meet.

Slide the tool firmly through the crease on one side of the device, twisting as you go to create separation.

When you reach the corner, carefully pry the two halves of the device apart.

There are small clips along the edges that need to stay intact in order to properly reassemble the device. Be very gentle when prying so as not to break the clips.

Repeat for the remaining three sides and corners.
