What's the FW version on your camera? On the previous model cameras, there's really not much indication that the FW update worked so you have to check information in the camera menu (third tab).
Please email tech support at support@spartancamera.com or call 770-582-0004 9 AM - 6 PM Eastern. If you email, make sure you specify exactly which model camera you have. They'll be able to send you the appropriate firmware, which you will copy to the SD card.
