Use the edge of a plastic opening tool to gently pry up the display assembly around its perimeter.

  • Use the edge of a plastic opening tool to gently pry up the display assembly around its perimeter.

  • Press gently on the home button to push it through the display and make sure it stays behind as the display separates from the iPhone. Otherwise, the home button cable may tear.

  • De-route the digitizer and LCD cables through the steel inner frame.

  • When reinstalling the display, carefully straighten the digitizer and LCD data cables, and feed them through the slot cut in the steel frame. This photo shows the display assembly being installed incorrectly, with a fold in the digitizer cable.

  • 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.

  • If the digitizer cable has been installed incorrectly, it will not reach its socket on the logic board. Do not attempt to pull it through by force, or it will tear. Remove the display assembly, straighten the cable, and feed it through to its full length, as shown.

  • 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. Be sure to separate the home button from the front panel. If the home button sticks to the front panel you may tear the home button cable.

Stap 12  ¶ 

  • Remove the display assembly from the iPhone.

  • Be sure to separate the home button from the front panel. If the home button sticks to the front panel you may tear the home button cable.

  • When replacing the display assembly, note the following:

  • 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.

  • After reassembly, connect the iPhone to an AC power source before turning it on for the first time. Once the iPhone has booted up successfully, you can disconnect the AC power.
