It will ask if you like to update firmware, using the arrow keys on the left of the camera select YES and press the circle button on the right side of the camera.
Wait till the update will go until it reaches 5/6 100%, give it about 10 seconds once it reaches that point.
Then grab a paper clip, and reset zBlackBox-HDi, to reset it there is a small hole on the right side of the camera where a HDMI port is.
After you have reset the camera, just turn it on and you are done.
