One day I tried to upgrade my NVR DS-7732N-E4 and then FIrmware dessapeared forever and my NVR becomes unuseful. I downloaded a new one from the Europe Hikvision page , change the language to CN (2) language and I successfully save it on the NVR with the Putty and TFTP32 apps via serial telnet. But when I restart it I still received the following message: "Your device is illegal, Please Call Factory". Please Could someone help me with the Hacked version in English for this NVR?
Thanks
