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

Step 5

Use a pair of tweezers to remove the the pressure contact near the battery connector.

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.

Step 6

Use the edge of a plastic opening tool to gently pry the battery connector up from its socket on the logic board.

Step 7

Insert the edge of a plastic opening tool between the battery and the outer case near the bottom left corner of the iPhone.

Run the plastic opening tool along the right edge of the battery and pry up at several points to completely separate it from the adhesive securing it to the outer case.
