Just a follow up, I managed to fix the issue, I used a different laptop (Windows 10 64 bit) with the 'Internet Explorer' browser with plugin, not the Edge browser. This time upgrade went through without issue. I obtained the last firmware from the EU site below...

I am trying to upgrade my HikVision NVR (DS-7608NI-K2 / 8P0820180322CCRRC0--------WCVU) which I purchased from ebay back in 2018, the region refers to 'RR' which I have read refers to 'other'. Can someone point me to which firmware I need to upgrade this NVR please? recently getting random NVR...

Thanks for the reply, I managed to get it working by using your 'donor' version, I've attached my 'mtdblock1' which did not work. Appreciate all the support you have given me!

Thanks for the reply, can I do a manual 'mtdblock1' template copy? I can connect to the camera via tftp and putty.

I went back to my previous 'mtdblock6' and then did the downgrader, camera is back online and back on 5.2.5.. I've attached my files (Porch.zip), appreciate if you can check if I did anything wrong, hopefully give it another go during week. Appreciate all your help.

Thanks for the information, I complete my other similar cameras, but when I did my final camera (DS-2CD2432F-I(W)) with the same method and firmware the camera never shows on my NVR or gets an IP. I can still connect via putty if I use a tftp server, appreciate any help on recovering this one...

Thanks for the reply, finally got to try this method! I tried both the v2 CN and EN files which copied across perfectly via the Hikvision TFTP program, but after powering off/on the camera would reply on 192.0.0.64 for about 10 secs but I could never get to the telnet prompt via putty and pings...

Hiya, I have three same camera models which were purchased from AliExpress with the same Chinese firmware (V5.2.5 build 141201), my cameras are connected to a HikVision NVR, and I can ssh/scp to the private camera IPs (192.168.254.x) via my Windows laptop. I can never get the CIFS share to work...

I had to buy the cable in the end as it kept on looping, I've gotten this far this evening, any assistance appreciated...it's complaining about a language mis-match, I guess as mine was from AliExpress....do you have any other firmware I could try? tips?

Thanks will try tftp again with a switch in the middle tomorrow evening, if it still fails will order the cable and connector, does the 4-pin connector go on this white socket on my nvr?

Thanks for the quick reply and file, I have a 7604N-E1/4P which was working fine on English, this is an Aliexpress version so guessing a clone... foolishly I upgraded the firmware with latest ML version (NVR_K41_BL_EN_STD_V3.4.6_160405.zip) and now it's looping with beeps after logo is...

Hiya - do you have the old English firmware link you can send me please? 3.0.10 build 141126 .... I have same issue as you had... thanks.

You sir are a legend! I followed your exact instructions and recovered my 'Hikvision DS-2CD2x32 camera' which was purchased from 'XinRay'... I had foolishly updated my firmware to the latest version (5.45 I think) and bricked my camera.. Using this firmware (EN downngrade_digicap.dav) -...
