Latest new NVR4XXX-4KS2_MultiLang_ V4.001.0000005.1.R.201126

Thanks for reply, @wittaj

They told me this NVR is Dahua Chinese original model but installed Vietnamese firmware. I just want to use English GUI since it is familiar in configuration so just upgrade once.
I understand that upgrading is my own risk so I'd like to check if anyone here upgraded this kind of NVR before. I have only this NVR at the moment so just want to have a checking.

From my experience, we can backup current firmware so that we can reinstall it when we face an issue during upgrading. Is there that kind of tool for Dahua NVR?

Thanks again!
did you figure it out?
I just got a 4108 with the same fw in vnese
