The camera cable connector is not secured by any locking or snapping mechanism. Hence, Apple sticks a small strip of black plastic with adhesive applied to the side facing the logic board behind the camera cable connector to keep it in its socket.

When moving the strip (cable retainer) out of the way, be sure not to break any surface-mounted components off the logic board.

Hold the end of the cable retainer down with one finger while you use the tip of a spudger to slightly lift the other end and rotate it away from the camera cable connector.

Disconnect the camera cable by pulling the male end straight away from its socket.

Pull the connector parallel to the face of the logic board, not straight up.
