I'm fairly confident that the V4 refers to the firmware level, not the hardware level. I've not heard of even V3 hardware the the 5xxx series..
Hi Andy am i reading this wrong, with this firmware update you have taken the NVR5216-4ks2 and given it AI capabilities? simular to the DHI-NVR55216-8P-I?I just finish the updating on my NVR5216-4ks2 V1 made in 2017 and NVR5216-16P-4KS2 made in 2017 both can work well, the version before update No. as below.

Hi MSNOW, can you tell me how you went to V3 from V4 please, I bricked my NVR tooYes, I reverted from v4 back to v3 twice but I’m now solidly on v4.

That’s a very old post from me but I found an older v3 bin file from Nov 2018 on my computer and copied it to a flash drive, stuck it in and installed it. It just overwrote the old version and I went back to normal. Eventually Dahua came out with a more stable version so was able to get to v4.Hi MSNOW, can you tell me how you went to V3 from V4 please, I bricked my NVR too
Yes I managed,[QUOTE = "cys, post: 438003, membro: 71833"]
Ho applicato questo aggiornamento al mio 5216-4ks2 ed è ora in loop di riavvio solo il logo ha appaers e niente più riavvio da solo ora voglio downgrade del mio vecchio firmware 3.216.00004 ma come posso aiutarmi!

Hi,
did you manage to solve?
I too have made the same mistake. Is it possible to solve somehow?
Thank you all
I can concur that that firmware update works perfectly on the NVR5216-16P-4KS2 (hardware version 1, not the 4KS2E) - problems such as cameras re-booting on motion detect, the NVR not being able to reliably communicate with the cameras, and general lagginess have all gone. Note though that the main Dahua web site no longer lists firmware for the 4KS2 - you'll want to go to Dahua's European FTP site to get it (don't under any circumstances install the firmware listed on their main web site - it's for the 4KS2E with v2 hardware, and will very likely brick your v1 NVR).Just wanted to add to the thread for future readers, I have an NVR5216-16P-4KS2E (hardware v1.0 per the info tab, havent checked the physical board) and used the firmware file "DH_NVR5XXX-4KS2_MultiLang_V4.001.0000000.1.R.200319.bin" directly from Dahua's website and it upgraded fine from version 3.216. LOTS of new features and a MUCH nicer GUI. So far no issues. We'll see though. Im considering doing a system restore just to give it a clean slate to start with on the new major firmware update.

I spotted that version after I'd already started downloading R.200319, but given that R.200319 is working perfectly for me so far, I'm in no hurry to move to R.201010. I've now downloaded it though, and will likely be upgrading to it in the next few months (or earlier if I spot a bug in R.200319).Would this be the current latest:

Has anyone tried it?
Best practice to factory reset then upgrade right?I spotted that version after I'd already started downloading R.200319, but given that R.200319 is working perfectly for me so far, I'm in no hurry to move to R.201010.

Having a quick look through the features listed in the release notes for both, I can't see any difference - and both releases state "none" in the "Bug Fixes" section. I'm thinking the only differences might be explicit support for recently-released cameras, or web interface changes to accommodate recent mutilations in web browsers (Chrome in particular seems to be setting its own standards without regard to W3C recommendations).
I don't see any reason not to use R.201010 - if I hadn't already committed myself to R.200319, I'd be going with the newer version too. Bear in mind of course that I certainly can't provide any guarantees - and as always, stay on top of your firewall (IMO, anyone enabling UPnP on their gateway should be banned from using the internet).
I prefer to do go that way indeed. However I see in previous posts to do a "system restore", that is something I counteradvice: if there are parameters that are redundant, obsolete or troublesome, you might run into possible issues on the new firmware.Best practice to factory reset then upgrade right?
I'd normally first upgrade and then do a setting reset (to make sure that newly-available options are set), but in this case I didn't (I was already at the end of my tether, thinking that if this didn't fix my previous issues, I'd dump everything and replace it with Hikvision equipment).Best practice to factory reset then upgrade right?
Same thoughts here - never save settings under one firmware version in the hopes of importing them into another firmware version. If the settings didn't carry over during the upgrade, it's far preferable to fumble through re-configuring things from scratch, than risking unknown issues by restoring incompatible settings....

I note from your previous post that you have the NVR5216-16P-4KS2E - you'll want to make sure that you only use firmware designed for the newer "E" variant of the NVR, as there've been a few horror stories from people who've used the wrong firmware for their NVR.Anyone tried upgrading to General_NVR5XXX-4KS2_MultiLang_V4.001.0000006.0.R.210208 yet? Looks like it came out March 19th, 2021 (LINK).
Edit: Or wait, is it the non-General version were supposed to use? It looks like there is also a "NVR5XXX-4KS2_MultiLang_V4.001.0000006.0.R.210208" that came out March 8th, 2021. What's the difference?!
