I was messing around in the settings and the advanced settings (988) and decided to try 966. This brings up an option to enable "Demo mode." I enabled it and backed out of the menus. Nothing had changed so I tried to get back to the settings menu but there was now a lock on it! I tried a few of the most obvoius pins, 0000, 1234, 9999, 1111, etc. but to no avail. Does anyone know the pin to unlock the demo mode? Do you think that leaving the stb unpluged will reset it? I know a simple reset does not remove it. Any help is much appreciated!
