LTS LTD8504K-ST firmware update issue

[tocjesse]

I have the LTS LTD8504K-ST and its got a pretty old firmware of v3.5.30.

On their site for this NVR they have the latest version of 4.21.002 for download

But in the description for it says "if current firmware is older than V3.5.37, please call tech support"

I've tried reaching their support with no luck. It seems like have to update to 3.5.37 first before the latest or it might fail?

Does anyone know where I can get V3.5.37

For anyone who finds this thread, I just upgraded my LTN8708K-P8 NVR to the newest firmware version!

If you were an installation professional calling tech support, they would instruct you to do the following IN THIS ORDER:

(1) Upgrade to NVRK_V3.4.96_180912 (if your firmware is older), then;
(2) Upgrade to NVRK_V4.32.110Build220805, then;
(3) Upgrade to NVRK_V4.74.200_230918 which is current and found at LTS's official website.

I will see if I can get the first two firmware version posted somewhere. Once I do later today, just search on the exact name (including the underscores), and in a few days search engines should pick the links up, and you'll find them. Or you can find my email at the top of tonytonini.com and I'll get them to you with a link. I am happy to, since someone did the same generous thing for me.

P.S. I used the web interface with MS's IE to do the upgrades and it worked nicely. Use MS Edge and then: Settings/Default Browser/ALLOW (sites to be reloaded in IE mode)/ADD A PAGE (set IP address to your NVR's).
