...... can make a try, maybe have bugs.....
Wondering which version 4.xxx doesn't have bugs? So far only v3.216 or below is running smooth. Tried differnt v400xx and every time got a very laggy picture while streaming over SmartPSS or Imou. Any improvement since then? Unless people can tolerate this issue. I can't

DO NOT UPGRADE TO THIS
has been released now.

Fellows, DO NOT UPGRADE TO THIS VERSION!!!! It will kill your NVR if you device to downgrade later back to v 3.216.
I did to my NVR4104 and so to another member of this forum. Looks like due to this Corona time the Dahua engineers decided to "improve the product" with the recent release to keep their jobs active.

Here are the steps I have done:

NVR4104 with the version V3.216.0000003.0 was upgraded to version V4.001.0000000.1. I had tried other version 4 releases and had issues every time with NVR performance, but was able to downgrade NVR back to v3.216. This time after the successful upgrade and confirmation that the IMOU keep disconnecting I downgraded back to 3.216. After downgrade it boots up with Dahua logo, then opens 4 camera display squares for 2 seconds and then disconnects the monitor. I can ping the . But can't connect with Config Utility or any other standard means.
Is there any way to recover the NVR from this issue?

I did the update several days ago, so far no problems
 
I see you have the same NVR as I do. Did you notice any issue with IMOHU or Smart PSS connection wit this new version 4? Mine was losing connection to cameras and disconnecting after less then a minute. This never happened with V3.216.

I only noticed disconnection with a ptz camera SD1A404XB-GNR, which was fixed with a default reset of the NVR

Apologies for necroing an old thread but I wasn't sure where to post this.
Just to confirm - the NVR4832-4K and NVR4832-4KS2 are two completely different models, yes?

I have the NVR4832-4K and I've been trying to update it using firmware from Dahua's page here but I have not been successful.
The system version is 3.210.0005.0 with Build Date of 2016-06-14 and Web Version 3.2.3.66468

Is there any upgrade path to bring this unit to a more recent firmware? If so, can I use the firmware from Dahua's page?
Thanks in advance.
