The same thing happened to mine.
I have yet to try their suggestion, but certainly hope we all don't have to send in these cameras to get the firmware reloaded
If your camera fails during a firmware update, wait a few hours, and reboot the camera prior to attempting the update again. There are a number of bandwidth or latency issues that can be resolved by trying at a different time.
If your camera indicates that the update has succeeded, but is then indicating that it is offline, please reboot the camera, and then check the light on the front.
If, after the boot cycle, the camera begins to blink a continuous green, please complete the setup again.
If it goes back and forth between blinking blue, and then blinking green more than twice, reset the camera, and then complete the setup again.
If the light goes solid blue, it should be working properly, please try accessing it again.
If the camera begins to blink a continuous blue, that indicates that the update was only partially applied, and the camera is now non-functional. I recommend setting up an RMA to have the camera come back to us to be repaired/replaced.
