DHI-NVR4108HS-8P-4KS2/L firmware upgrade

[Ajithjau]

I have a DHI-NVR4108HS-8P-4KS2/L running firmware V4.002.0000000.3.R, Build Date: 22/03/2022
Is there a newer update? I wanted to upgrade as I dont have a menu option to Upload Custom Siren Audio
Dont have an option Alarm->Alarm-out-port

We have had people play the horrible game of fuck around and find out with firmware fuckery recently.
Most likely you’ll be fine, but it has its risks
