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. 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. Remove the two 1. Starting near the cellular antenna cable, use the edge of a plastic opening tool to peel the antenna off the speaker enclosure.

You need a pentalobe screwdriver to open your phone. Remove the two pentalobe screws at the bottom of the enclosure. They are located to the right and left of the dock connector. Put the screws in the same compartment of your organizer tray. Use your thumbs or the palm of your hand to push the back cover of your iPhone about 4 mm away from the bottom of the phone where the dock connector is see figure 1.
Remove the two Phillips screws on the battery connector using a Phillips screwdriver see figure 1. If the contact point breaks off but the soldering points are still intact, you can solder the contact point back on. Now carefully lift off the battery connector by inserting the pointed ESD spudger slightly below the silver cover plate see figure 2. For the rest of the repair, you can also use the metal laboratory spatula instead of the spudger. This may make some steps easier for you.
However, we explicitly recommend using the ESD spudger produced specifically for precision electronics. The antenna cover is under the battery connector. Remove the cover and put it in the same compartment of your organizer tray as the Phillips screw you removed before.
