Andy, Are you referring to 7.1 210827 on Dahua web site? I have NVR5232-16P-4KS2E just purchased from your aliexpress, so should I not use latest FW 7.1?

Andy,
I have another question about your upgrade firmware and Dahua's International firmware. Why is there a difference in where we get them if the NVR's are the same or are they? Are the one's we get from aliexpress/Amazon any different because they are English version of Chinese models. I have used firmware from Dahua's USA web site for my NVR without any failures as they are named exactly the same as your firmware and that from Dahua's Int'l web site.

I believe Andy works closely with some of the Dahua developers to quickly fix many of the known issues and bugs prior to Dahua fixing them.

I've been using the 6.1.R.210709 since Sept 11th without any issue already. Not sure if this one that Andy posted about is any different.

I've learned from this site that if everything is working fine then no need to upgrade or fix. I usually wait 6months or so and then upgrade just so that I don't create a situation where my NVR firmware version becomes extremely dated and then I can't upgrade to the latest release without an additional intermediate step.

@mazut says that latest release seems to be working for a while for him. Will wait and see what Andy finds as well.

Normally our NVR FW no big difference compare to dahua official firmware, i just try not to use dahua logo fw on our devices, but function totally the same.
For cameras, we have lots of re-design, can be better than their official fw.

one feature that I miss (or didn't find) in all of the Dahua NVR is the ability to instant zoom:
The Hikvision enables you to mark an area with the mouse and zoom in. Miss it in Dahua.

The download link is no longer valid. I can load the same version directly from Dahua but is there a reason the link was taken down? firmware problem?

Hi @EMPIRETECANDY,

I wish I had of found this forum before I tried to update my NVR, I have bricked it and hoping you can help me unbrick it.

I have NVR5208-8P-4KS2 (I think it's V1)

I can access it with tftp64 & PuTTy, I have managed to get the logo back on boot to show as this disappeared but I think I maybe flashing the wrong update files.

I have hundreds of those NVR5xxx-4KS2's in maintenance with different version numbers, and i have barely never bricked anything. I have some, but this was not because firmware.
Latest FW is anyway with date 211231, runs on every version so far just fine.

@mally You need full upgrade folder, with update.img file inside

I have put this on a new 5208-4ks2 -
*no longer have Live View - AI mode on the main display, it is there but nothing populates the side bar.
*Also have see that the PTZ linkage on IVS trigger no longer works. It will not save when applied and gives a message " Reached max ability of AI analysis"
*Can not roll back this Firmware.

First: yes you can roll back, i did it today with one nvr that had compatibility issue with one very old Dahua PTZ camera.
Other issues might be solved if you do "factory default" reset to this unit and set it up again.

I will give it try after another reset, but I tried several roll backs and had no luck.
