I just did my update...I followed the written instructions provided and had no problems updating the craft and the RC...the battery evidently updates at the same time the craft does. I think if we leave the bin file on the camera card, subsequent batteries will update when the craft powers up. I did do an IMU calibration and calibrated the compass as well. The Inspire fired up like it normally does when I moved the joy sticks in the start up position to fire up the craft. I didn't really do anything different to unlock the motors.
