How to Install iPhone 4S Dock Connector ??

Use a pair of tweezers to pull the lower microphone away from the bottom edge of the iPhone.

Note the folding of the cable and the positioning of the rubber microphone cover for reassembly.

Remove the dock connector assembly from the iPhone, minding any cables that may get caught.

Slide the rubber cover off the microphone attached to the old dock connector and transfer it to your new dock connector.

The ribbon is very fragile and can easily be torn when placing the rubber cover onto your new part

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
