Edit 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.

Edit Step 2 ¶

Push the rear panel toward the top edge of the iPhone.
The panel will move about 2 mm.

Edit 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.

Edit Step 4 — Battery ¶

Remove the single 1.5 mm Phillips screw securing the battery connector to the logic board (if present).

Edit Step 5 ¶

Use the edge of a plastic opening tool to gently pry the battery connector up from its socket on the logic board.
Be very careful to only pry up on the battery connector and not the socket on the logic board. If you pry up on the logic board socket, you may break it entirely.

Edit Step 6 ¶

Pull up on the exposed clear plastic tab to peel the battery off the adhesive securing it to the iPhone.
Remove the battery.
Do not remove the plastic tab from the iPhone.
