Just hit this error myself -- found an easier way than restoring from backup. First, download the latest iOS7 version (I used an ipsw from this website: http://www.iphonehacks.com/2013/09/update-ios-7-beta-ios-7-public-release.html http://www.iphonehacks.com/2013/09/update-ios-7-beta-ios-7-p...) Open up iTunes and go to your iPhone, and press alt/option + the "Check for Update" button. This will open up a window that will allow you to browse to your ipsw download. Choose the iOS7 ipsw you downloaded for your phone, and choose it. After 20 minutes, your iPhone will update, and you'll be ready to go -- no restore required.
