  • Do not pull the front glass completely away from the frame. Doing so may result In damage to the digitizer cable.

  • If the glass is cracked (which it probably is since you're replacing it) removing the panel is likely to cause it to bend, kicking off small shards of glass. Before you do this step, cover the front with clear tape, then perform the actual removal over a trash can. Protective eyewear would also be prudent.

Paso 9  ¶ 

De-route the digitizer and LCD cables through the steel inner frame, and remove the display from the iPhone.

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.

  • 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 not been installed correctly, 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.
