Introduction

This is not a pleasant repair. The device is full of adhesive. Removing the display assembly from front panel (or "mid chassis") can easily result in the destruction of the front panel bezel and digitizer. I suggest that you replace the entire digitizer, rather than one portion. If you want a beautiful front panel bezel, you will definitely need to replace that part, as well.

    • This rubber spacer is held on by a weak adhesive. Be careful with this during reassembly, as it may catch and crumple as you put the back panel back the phone.

    • Heat black Mylar shield for easier removal.

    • As you can see, we attempted to peel off the Mylar shield before heating it. It required more force than we were comfortable with, so we turned up the heat!

    • Gently separate upper logic board from mid chassis. The upper logic board is held to the mid chassis by copious amounts of strong adhesive.

    • Once the adhesive-laden logic boards are separated from the mid chassis, the entire assembly easily comes off.

    • Be careful when handing the logic board assembly. We could have separated out each part, but decided it was a waste of time. The cost of cutting this corner is extra care when handling the logic board assembly.

    • Blast the front panel with heat and pry between the display assembly and front panel bezel, working one or several guitar picks around the display assembly.

    • Once the display assembly is loosened from the front panel, it will fall away.

    • The front glass came off easily, but the digitizer was much more difficult to remove. The adhesive holding together the display assembly is much weaker than the adhesive holding the display assembly to the front panel.

    • While creating this guide, I utterly destroyed the front panel bezel and digitizer. Replacing the display assembly was a breeze--but removing the digitizer required nearly a dozen reheats of the front panel. To replace the bezel, you will need a new "mid chassis" (that's the front panel piece the digitizer is so powerfully glued to).
