    • Remove the two 1.8 mm Phillips screws securing the dock connector cable cover to the logic board.

    • Remove the metal dock connector cable cover.

  2. LTGglSRdd5SCnJPs

    • Use the edge of a plastic opening tool to pry the dock cable up from its socket on the logic board.

    This repair went well overall, but I thought I would add a couple comments on this step. Once I got my iPhone back together, it would not charge and the home button didn't work. I took it back apart and realized that the dock cable was not seated. After many attempts, I finally got it seated correctly and you can feel it "click" into place. The metal rectangle that holds it on should sit FLAT and not have any bulge. If you have a bulge, that means the dock cable is not seated correctly.

    • Remove the 1.6 mm Phillips screw securing the pressure contact to the logic board near the vibrator.

    • Remove the pressure contact.

    • When reinstalling the pressure contact, be sure to clean it with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.

    • Use a plastic opening tool to lift the speaker enclosure assembly out of the case, being sure not to damage the EMI fingers on the attached Wi-Fi antenna.

    • Remove the speaker enclosure assembly.

    • Before reinstalling the speaker enclosure assembly's screws, be sure the Wi-Fi grounding fingers are installed below the lip in the iPhone's metal case as seen in the third picture.

    • Before reassembly, be sure to clean all metal-to-metal contact points between the grounding fingers of the Wi-Fi antenna and the case of the iPhone with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause wireless interference issues.

Conclusion

To reassemble your device, follow these instructions in reverse order.
