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.
Stap 12 ¶
Remove the display assembly from the iPhone.
You may have to reuse the earpiece grille and the clear plastic ring around the front facing camera from the old/damaged assembly. This will depend on where you buy the replacement part.
Your replacement display may come with colored plastic film on the back of the LCD. If so, use the pull tab near the home button to peel the plastic film from the LCD before installing the new display in your iPhone.
After reassembly, note the following:
Clean the touchscreen surface with an alcohol wipe prior to turning the iPhone back on. The alcohol helps dissipate any lingering static electricity, which can cause problems with the display.
