I Have a DS-7604NI-K/4P NVR, I've tried to update the firmware to the newest version, current is V4.30.085 build 210409.
I would like some advice as when I extract the digicap.dav file, from what I believe is the latest update it doesn't update.
Regards
What firmware version are you trying to update to?
Looking at the version you are currently running it looks like you have a DS-7604NI-K1/4P(B) version, as a (B) hardware version the latest version that this model supports will be V4.30.096_build221220 (see your version in this list and the latest version bellow it).
