Thread the screen cable and digitizer cable out of their cutouts, then remove the display.

Clean all adhesive residue from the phone frame. Adhesive that's left behind may apply uneven pressure against the replacement screen and potentially damage it.

Apply a pre-cut adhesive, or double-sided tape to the phone frame's perimeter.

Peel all plastic liners from the back of the replacement screen to expose the adhesive.

Carefully thread the screen cable and the digitizer cable through the phone frame's cutouts.

Lay the screen onto the frame and place some books on top for an hour to help the screen adhesive bond to the frame.
