What is the build date you have currently? You cannot just update to V4 without the correct path. You need to be on the January 2019 firmware on V3 before you can apply the first V4 version. Trust me

Did you do the sequential updates to get it to V8? There is a path of updates needed to do such an update. If it did not work, you might need to fully factory default it in Recovery Mode. That might work but you should push Dahua for support
From the glance I had of it, its not bad. I'd be happy to use it over the v4 AiOT GUI on EI models which I was not impressed with. Still to try web browser usage
