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 5
¶
-
Use a plastic opening tool to pull the pressure contact from underneath 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.
-
Take notice of the small black ground clip on the upper screw of the battery connector.

-
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.
