Step 1 — Rear Panel Before disassembling your iPhone, be sure it is powered off. Remove the two 3.6 mm Pentalobe screws next to the dock connector. During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws. The 5-Point Screwdriver should only be used once, as it has the potential to strip the screws.
Step 2 Push the rear panel toward the top edge of the iPhone. The panel will move about 2 mm.
Step 3 Pull the rear panel away from the back of the iPhone, being careful not to damage the plastic clips attached to the rear panel. Remove the rear panel from the iPhone.
Step 4 — Battery Remove the following screws securing the battery connector to the logic board: One 1.7 mm Phillips screw One 1.5 mm Phillips screw
Step 5 Use a pair of tweezers to remove the the pressure contact near the battery connector. 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.
Step 6 Use the edge of a plastic opening tool to gently pry the battery connector up from its socket on the logic board.
Step 7 Insert the edge of a plastic opening tool between the battery and the outer case near the bottom left corner of the iPhone. Run the plastic opening tool along the right edge of the battery and pry up at several points to completely separate it from the adhesive securing it to the outer case.
Step 8 Use the exposed clear plastic pull tab to peel the battery off the adhesive securing it to the iPhone. Remove the battery.
Step 9 — Speaker Enclosure Assembly Remove the following screws securing the dock connector cable cover to the logic board: One 1.5 mm Phillips screw One 1.2 mm Phillips screw Remove the metal dock connector cable cover.
Step 10 Use the edge of a plastic opening tool to pry the dock cable up from its socket on the logic board.
Step 11 Peel the dock connector cable off the adhesive securing it to the logic board and the side of the speaker enclosure.
Step 12 Use the edge of a plastic opening tool to pry the Wi-Fi antenna cable up from its socket on the logic board. De-route the Wi-Fi antenna cable out from under the metal fingers attached to the logic board.
Step 13 Remove the two 2.4 mm Phillips screws securing the speaker enclosure assembly to the outer case.
Step 14 Remove the small black spacer that was under the Phillips screw near the vibrator.
Step 15 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.
Step 16 — Cellular Antenna Remove the two 1.6 mm Phillips screws securing the cellular antenna to the speaker enclosure.
Step 17 Starting near the cellular antenna cable, use the edge of a plastic opening tool to peel the antenna off the speaker enclosure. Continue peeling the cellular antenna off the speaker enclosure, being careful not to rip the gold bracket attached to one of its edges. Remove the cellular antenna.
Step 18 When installing a new cellular antenna, be sure to slide the gold bracket over the ear molded into the speaker enclosure before sticking the antenna down.
