Installing iPhone 4 Headphone Jack & Volume Control Cable

Step 1 — Rear Panel
Before disassembling your iPhone, be sure it is powered off. Apple hasrecently substituted the two Phillips screws with 5-Point "Pentalobe" screws. If your iPhone 4 has 5-Point "Pentalobe" screws instead of Phillips, please refer to the second picture. 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 neededto 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 6
Use the clear plastic pull tab to gently lift the battery out of the iPhone. Be careful when removing the battery with the plastic pull tab. On some units, Apple uses an excessive amount of glue, making it virtually impossible to remove the battery in this fashion (with the tab possibly tearing due toexcessive force). For batteries that "stick", you could use the iPod opening tool to assist (take extra care whilst doing so). Remove the battery. Before reconnecting the battery connector, be sure the pressure contact (shown in red) is properly positioned next to the battery connector. Before reassembly, be sure to clean all metal-to-metal contact points on the pressure contact as well as its contactpoint on the rear panel with a degreaser such as windex. The oils on your fingers have the potential to cause wireless interference issues.
