    • Remove the following two screws:

    • One 1.2 mm Phillips

    • One 1.6 mm Phillips

    • Remove the thin steel dock connector cable cover from the iPhone.

    • Before reassembly, be sure to clean all metal-to-metal contact points on the dock connector cable cover with a de-greaser such as windex. The oils on your fingers have the potential to cause wireless interference issues.

    • Use a plastic opening tool to gently pry the dock cable connector up off the logic board from both short ends of the connector.

    Ahh! I had a problem here. First two times, I still had no charging and home button,Third time I got it. When putting it the cable back on to the logic board it never sat right. On my third try I heard a click! I finished putting everything else back together and it worked.

    • Carefully peel the dock ribbon cable off the logic board and the lower speaker enclosure.

    • Do not use excessive force to peel the dock ribbon cable off the logic board. Doing so may tear the cable.

    unfortunatelly the gold shimmering rubber layer that kept down the cable tore up a bit and one of the gold contact lines is now visible. Will this interfere, is the gold shimmering rubber shielding the cable from the metal or is it "just" rubber that keeps the cable down?

    In other word; will I have to replace the gold shimmering rubber layer or can I just turn it back down even if it's a bit torn?

    • Use a plastic opening tool to pry the lower antenna connector up off its socket on the logic board.

    The uFL connector on the board does not hold any more. Can anyone suggest me how to make this stay again, or do I really need to replace the antenna?

    • 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.

    err 2 of the grounding pins broke in the process of reinstallation.. how many do you reckon before wifi = 0
