I upgraded to 7.7 with no issues however a handfull of my 5011 cameras are in critical state with the Error "Operation failed: Media server reported the error Failed to update device (Device HwId mismatch.)." The cameras are on the current FW (1.6.7). I tried to replace the config and repair the config and nothing works. However I can replace the camera and select new camera and just put its info back in and that works. Looking for a faster solution.
