So I recently had a NVR that was locked out, as in no username and password. (Dahua Based) I defaulted the password and set it up for testing at home, and stupidly put it in a DMZ, openning port 22 SSH to it without changing the SSH default login details.

Anyway long story short, its been hacked and someone has what I beleive erased the entire file system. I have been trying to boot to U-Boot via serial with no luck.

I guess my question is, if the file system is erased, does that include U-Boot and therefor making it rubbish now?

I cannot access this thing via serial whatsoever, tried multiple USB serial cables with no luck!


Its a nice little NVR I could use if I could get the damn thing working!

Thanks
