vjorge 0 Posted October 20, 2014 Hi, I have an sannce 4CH CCTV DVR 960H H.264 800TVL that after an firmware upgrade it no longer boots. When i power it on i can see the sannce logo but then it blackens out the screen. Is there a way to revert or flash the previour firmware? Many thanks.

Norwich Dave 0 Posted February 13, 2017 Unplug all usb's, and then with just monitor attached, power it up. You will then be looking at the menu screen. Attach usb mouse & reboot. Share this post Link to post Share on other sites
