Installing iPhone 4S Display Assembly

Installing iPhone 4S Display Assembly Replace a cracked front panel or a broken display on your iPhone 4S. Difficulty: Difficult
Sections: Rear Panel 3 steps Battery 5 steps Dock Connector Cable 4 steps Rear Camera 4 steps SIM Card 1 step Logic Board 9 steps Vibrator 1 step Speaker Enclosure Assembly 3 steps Display Assembly 8 steps	Tools: Phillips #00 Screwdriver Plastic Opening Tools Small Flathead Screwdriver Tweezers iPhone 4 5-Point Pentalobe Screwdriver iPhone SIM Card Eject Tool
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 — Vibrator Wedge the plastic opening tool between the vibrator and the side of the iPhone. Pry the vibrator up to release it from the adhesive securing it to the iPhone. Remove the vibrator.

Step 28 — Speaker Enclosure Assembly Remove the two 2.4 mm Phillips screws from the sides of the speaker enclosure assembly.

Step 29 Remove the small plastic bracket that was installed under the screw closest to the dock connector cable.

Step 30 Remove the speaker enclosure assembly from the iPhone. 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 second 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 31 — Display Assembly Remove the small pieces of black tape covering the display mounting tabs.

Step 32 Remove the 1.5 mm Phillips screw securing the display assembly near the power button.

Step 33 Remove the 1.5 mm Phillips screw near the headphone jack.

Step 34 Remove the 1.5 mm Phillips screw near the lower microphone.

Step 35 Remove the 1.5 mm Phillips screw near the dock connector cable.

Step 36 Loosen the three large-headed Phillips screws along the volume button side of the iPhone about one half turn. It is not necessary to completely remove these screws. When reinstalling the display assembly, be sure the washers are closest to the screw head (as seen in the second picture).

Step 37 Loosen the three large-headed Phillips screws along the other side of the iPhone about one half turn.

Step 38 Use the edge of a plastic opening tool to gently pry up the display assembly around its perimeter. Remove the display assembly from the iPhone. When reinstalling the display assembly, be sure the digitizer and display data cables are completely pulled through the slot cut into the outer case before pressing the display assembly down into the outer case. Failure to do so will cause the digitizer cable to not reach its socket on the logic board.
