I am facing a problem that I couldn't find on internet. When I change any configuration of my DVR and save it, it works fine. But after restart it goes back to previous configuration. I tried to factory reset, but after factory resetting when the device restarts, it goes back again to that configuration. I tried replacing the CMOS battery. But it didn't work out. I don't know what to do now. Is there anyone who could help me about it. Please help me. I need to turn on continuous recording but it goes off when it restarts.
