Before disassembling youriPhone, be sure it ispowered off.
Remove the two 3.6 mm Pentalobescrews next to the dock connector.
During reassembly, werecommend you replace the5-point screws with equivalentPhillips screws. Our Liberation Kitprovides the tools and screwsneeded to replace the Pentalobescrews with Phillips screws.
The 5-Point Screwdrivershould only be used once,as it has the potential to strip thescrews.
Remove the following screwssecuring the battery connector tothe logic board:
One 1.7 mm Phillips screw
One 1.5 mm Phillips screw
Step 5
Use a plastic opening tool to pull the pressure contact from underneath the batteryconnector.
When reinstalling the pressure contact, be sure to clean it with a degreaser such aswindex or isopropyl alcohol. The oils on your fingers have the potential to createwireless interference.
Use the edge of a plastic openingtool to gently pry the batteryconnector up from its socket on thelogic board.
Be very careful to only pryup on the battery connectorand not the connector on the logicboard. If you pry up on the logicboard connector, you may breakthe connector entirely.
Step 7
Insert the edge of a plastic opening tool between the battery and the outer case near thebottom left corner of the iPhone.
Run the plastic opening tool along the right edge of the battery and pry up at several pointsto completely separate it from the adhesive securing it to the outer case.
Carefully lift the logic board fromthe end closest to the speakerenclosure and slide it away fromthe top edge of the iPhone.
Remove the logic board.
Before reassembly, be sureto clean all metal-to-metalcontact points on the logic board(not the mating halves ofconnectors) with a de-greaser suchas windex or isopropyl alcohol. Theoils on your fingers have thepotential to cause groundingissues.
Step 26
Be sure not to lose thesmall grounding finger forthe rear facing camera near thepower button. This finger rests ontop of the PCB, screwed down, andcovered with the adhesive blackplastic tape.
Remove the speaker enclosure assembly from the iPhone.
Before reinstalling the speaker enclosure assembly's screws, be sure the Wi-Figrounding fingers are installed below the lip in the iPhone's metal case as seen inthe second picture.
Before reassembly, be sure to clean all metal-to-metal contact points between thegrounding fingers of the Wi-Fi antenna and the case of the iPhone with a de-greasersuch as windex or isopropyl alcohol. The oils on your fingers have the potential to causewireless interference issues.
Remove the 1.5 mm Phillips screwnear the dock connector cable.
