hello to everyone, unfortunately I did a damage. I bought a turbo 4 dvr 7208 Huhi k1 yesterday I downloaded two updates from hikvision site being careful but after the last update, the DVR can no longer enter the menu, I can not put admin as a user but I can only put the password can you help me? I tried with tftp but it does not do anything like I can do? damn me and those damn updates
