  • Apply a suction cup to the lower half of the front panel, just above the home button.

    • Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.

Aggiungi Commento

  • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

  • Insert an opening pick or other thin pry tool a few millimeters into the gap.

    • The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

Aggiungi Commento

  • A rubber gasket on the bottom of the Lightning connector protects your iPhone from liquid and dust intrusion. If you are installing a new Lightning connector assembly, you may need to carefully remove and transfer the gasket to the new part.

  • The small adhesive patch on the bottom of each microphone also protects your iPhone from liquid and dust intrusion. For best results, replace the two adhesive patches before installing your Lightning connector assembly.

  • Important: During installation, correctly position your new Lightning connector assembly so that the cutouts in the cable are exactly centered around the four screw bosses in the rear case. Otherwise, the flex cable will be misaligned and you won't be able to reconnect it to its socket on the logic board.
