SUCCESS!!!! So far, so good! Thank you, sincerely for both your assistance and patience. I am grateful. Kind wishes, Steve.

One final question before I give it a go... is it OK to jump straight to the latest firmware? From 3.0.8 to 3.4.91? I'm seeing lots of comments about missing the versions in between causing problems.

Nope, it won't upload the file. :-(

Hmmmm... firmware mismatch. It won't proceed with the .dav file from 海康威视——以视频为核心的物联网解决方案和数据运营服务提供商 when I try with the VGA GUI. Will try with the web GUI.

All three cameras report as follows: <?xml version="1.0" encoding="UTF-8"?> <Language xmlns="http://www.hikvision.com/ver10/XMLSchema" version="1.0"><type>english</type></Language> <?xml version="1.0" encoding="UTF-8"?> <Language xmlns="http://www.hikvision.com/ver10/XMLSchema"...

I final got the saved files off the NVR, no idea what I did wrong the first time. I repeated the process and if was fine. I'm not experienced with hex editors at all I'm afraid but I opened the saved block0 and this was the closest I could find to what you asked.

It was indeed on a PC. I'll rerun the procedure again later tonight and see if a different USB port makes a difference.

That's interesting, I just checked the USB stick I backed up the NVR firmware too like you instructed and it's empty?

I'm fairly sure the specific firmware for the DS-7800 is found here... 海康威视——以视频为核心的物联网解决方案和数据运营服务提供商 However, it's Chinese only, which would stand to reason that the language will not have the option for English. I've checked the firmware .dav file from this site with Hiktools05r1 and can...

Yeah, I can confirm all 3 cameras are DS-2CD2332-I, Firmware Version V5.2.5 build 141201, Encoding Version V5.0 build 140714, all CN.

Yeah, as far as I know they're all CN cameras. I have three and I think, though I will double check when I can, that they're all DS-2CD2332-i on 5.2.5 and CN. Also, just checking, are these the firmware for a 7804? Having a look, this model number isn't shown in any of the release notes?

How do I proceed from here master Jedi? :-)

OK, done that step. :)

...opps, missed your reply. Am just trying the HDMI interface...

OK, the first stumbling block. I'm afraid to say I can not setup the NetHDD nor see the USB on the NVR. I don't own a physical NAS, and everything I try to get the NVR to see a PC drive on my network fails. I've tried all kinda of USB drives on all the USB ports on the NVR and nothing...

I think USB is out of the question, I just can't get it to acknowledge the USB at all I'm afraid to say. I'm trying the NetHHD option, but it's taking a bit of time and brain power at this end, as I've never used this feature of the NVR before. I'll post my progress as soon as I can and...

...and thank you alastairstevenson, you help is very much appreciated. :-)

Hello all, I'm wonder if someone more experienced in updating Hikvision firmware would be willing to help talk me through the process of updating my DS-7804N-E1. I have read through the forum but as an inexperienced user, its not filled me with confidence that it's a straight forward nor simple...
