¶
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.

Edit Step 10 ¶
Remove the 1.6 mm Phillips screw securing the pressure contact to the logic board near the vibrator.
Remove the pressure contact.
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.

Edit Step 14 ¶
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.

Edit Step 16 ¶
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.
