Make sure the suction cup is firmly attached to the front panel assembly.

Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

With a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while you pull up with the suction cup.

There are several clips attaching the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

Continue to pry up around the sides of the front panel assembly, detaching the clips along the left and right side.

Do not try to completely remove the front panel assembly from the rear case, as there are several ribbon cables still attached at the top of the iPhone.

Once the clips have been released on the bottom and sides of the front panel assembly, pull the bottom of the assembly away from the rear case.

Lift the front panel assembly slowly up to about 90 degrees from the rear case.

Front-facing camera and sensor cable

Digitizer cable

LCD cable

If that happens, simply reconnect the cable and power cycle your phone. The best way to power cycle your phone is to disconnect and reconnect the battery.
