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 — Dock Connector Cable 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 — Rear Camera If necessary, use a pair of tweezers to remove the outer plastic ring located on top of the rear camera's flash assembly.
Step 14 Remove the following four screws securing the cable cover to the logic board: One 2.7 mm Phillips screw One 2.6 mm Phillips screw One 1.3 mm Phillips screw One 1.2 mm Phillips screw
Step 15 Use the edge of a plastic opening tool to pry the cable cover tabs out of their slots cut into the EMI shield on the logic board. Lift the cable cover from its edge nearest the top and remove it from the iPhone.
Step 16 Use the edge of a plastic opening tool to pry the rear camera connector up from its socket on the logic board. Be careful not to break any components off the surrounding area on the logic board as you pry upwards. Remove the rear camera from the iPhone.
Step 17 — SIM Card Use a SIM card eject tool or a paperclip to eject the SIM card and its holder. This may require a significant amount of force. Remove the SIM card and its holder.
Step 18 — Logic Board Remove the five cables near the top of the logic board in the following order: Headphone jack/volume button cable Front facing camera cable Digitizer cable Display data cable Power button cable (located underneath the headphone jack/volume button cable as shown in the second picture.) To disconnect the cables, use the edge of a plastic opening tool to gently lift their connectors up and out of the sockets on the logic board. Be careful not to break any of the small and delicate surface mount components as you disconnect the cables.
Step 19 Remove the 1.5 mm Phillips screw securing the grounding clip to the logic board near the headphone jack.
Step 20 Lift the small grounding clip up off the logic board and remove it from the iPhone.
Step 21 Use a small flathead screwdriver to remove the 4.8 mm standoff near the headphone jack.
Step 22 Use the edge of a plastic opening tool to disconnect the wi-fi antenna from the logic board.
Step 23 If present, peel the piece of black tape covering the hidden screw near the power button. Remove the 1.6 mm Phillips screw securing the logic board near the power button.
Step 24 Remove the following screws securing the logic board to the case: One 2.5 mm Phillips screw near the vibrator motor One 2.4 mm Phillips screw One 3.6 mm standoff along the side of the logic board nearest the battery opening. Use a small flathead screwdriver to remove the single 3.6 mm standoff.
Step 25 Carefully lift the logic board from the end closest to the speaker enclosure and slide it away from the top edge of the iPhone. Remove the logic board. Before reassembly, be sure to clean all metal-to-metal contact points on the logic board (not the mating halves of connectors) with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause grounding issues
Step 26 Be sure not to lose the small grounding finger for the rear facing camera near the power button.
Step 27 — Front Facing Camera Use the edge of a plastic opening tool to carefully pry the metal front facing camera retainer away from the case of your iPhone. Remove the front facing camera retainer.

Use a pair of tweezers to unfold the earpiece speaker from its recess in the outer case, Do not completely remove the earpiece speaker as it is still attached to the power and sensor cable assembly.
Step 32 Use the edge of plastic opening tool to gently move the top sensor assembly away from the outer case. Gently pry the top sensor assembly off the outer case.
Step 33 Lift and remove the power and sensor cable assembly from the iPhone. Be sure not to lose the small retainer clip located on the top sensor assembly.
Step 34 — Earpiece Speaker Assembly Use the edge of a plastic opening tool to peel the earpiece speaker off the foam adhesive securing it to the iPhone. If you wish to reuse the earpiece speaker, try not to tear the foam adhesive that secures it to the iPhone's case. Remove the earpiece speaker.
