Hi
I have Dahua DHI-NVR4104-W - upgraded firmware to DH_NVR4xxx_Eng_P_V3.200.0000.9.R.20150529
at first it did ask me to set new password - which i did then after some set up i did try to login again - no success.Now i have admin account locked - 888888 and 666666 users doesn't exists (? - changed passwords for them before upgrade but they still should be there) after upgrade.Did try 12.01.2015 account superpassword with no success .Any advise - how to proceed without taking battery out as I'm 1000 miles away from this system and would have to ask friends to do it ....
