Slide an opening pick underneath the top portion of the Lightning connector assembly flex cable, and begin separating the cable from the rear case.

Gently slide the pick toward the outside edge of the iPhone (away from the battery).

Part of the wireless charging coil lies directly underneath this portion of the Lightning connector flex cable. Aggressive prying may damage the coil.

If needed, use your hair dryer or iOpener repeatedly to re-heat the area behind the Lightning connector assembly flex cable in order to make it easier to separate.
