You must now disconnect the screen and digitzer, which are glued together.

You may need to use hot air to heat up the adhesive keeping the screen and digitizer together. This will make separating them much easier.

Using a plastic opening tool, slip the tool between the screen and the digitizer and slowly pry them apart.

After this is complete, orient your new screen in the same manner as the old one, attach it to the digitizer with a strong adhesive, and reassemble.
