Hello to all,

After trying to upgrade the firmware of my old Dahua NVR, now I can't login :(
Available usernames for login are 888888, admin and 666666, tried with default passwords but no one worked.

Before update it was on sys vers. 3.210.0001.0, build date 24/01/2015.

It has a reset switch on the motherboard, but holding it doesn't make any changes. It is the same holding it on boot for 5/10/20/60 sec. - after releasing it , it comes back to live view.
I tried with the date recovery, because it was switched off with removed battery for a month, and I think it returned to 01.01.2000 but the default password for that date doesn't work.

Any help how to login again?
Thanks in advance!

Hello,

Yes, tried the default combinations of username and password but they don't work.
I think I bricked the NVR and it needs to be reflashed, but I can't find the original firmware for it
