paco06 0 Posted February 1, 2016 Hello all, I am facing this issue : I have a Dahua DVR with some users account, all have forgotten their passwords.. I can enter locally with super admin password . User's password may be changed then but after a power reset, the OLD configuration is coming back, ever and ever with unknown passwords. Battery has been removed for 20 minutes, factory reset done, no way . Still the old config. appearing with network, accounts etc. I have found nothing regarding automatic config backup. Interestingly enough, when I successfully change the password, the following message issue : << Sauvegarde config. arrêtée >> wich means "Configuration backup stopped" as if the new configuration could not be saved. Please anybody had this kind of behavior before ? Thanks a lot Patrice Share this post Link to post Share on other sites
