Add Note 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.
