Use the edge of a plastic opening tool to gently pry up the display assembly around its perimeter.
De-route the digitizer and LCD cables through the steel inner frame.
When the front panel has been correctly installed, both the LCD and digitizer cables should be immediately next to one another and should be the same length, as shown in the second photo.
During reassembly, do not touch the metallic area at the base of the LCD data cable, as this can cause problems with the LCD. If you do touch it accidentally, clean it gently with an alcohol wipe before continuing.
