Hikvision - DS-7616NI-E2/8P

[TFBUNDY]

Can somebody please send me firmware upgrade for a hikvision nvr ds-7616ni-e2/8p version 3.0.8 so I can use new hikvision cameras ds-2cd2335-i that are version 5.3.3

I think I need to be above version 3.3.3 ?????

Here are some publically-available downloads. But be aware that upgrading can have adverse consequences as the camera region enforcement is activated in the updated firmware.
I'd recommend making a backup of the existing firmware and settings so you can get back to where you started if you need to. With telnet access make a copy of mtdblock2, and in the web GUI backup both the device config and the camera configs.

What I strongly suggest if you think about upgrading is to back up your existing firmware so you have a way back should you wish.
All you need is a copy of mtdblock2 in the as-delivered state. But copy mtdblock0 and 1 also.
The easiest way is if you can add a NAS destination via the GUI. It does not need to be formatted.
Something like this for an NFS mount.
Use 'mount' to find the mount point, then something like:
cd /mnt/tnfs01
umount /dev/mtdblock2
cat /dev/mtdblock2 > mtdblock2_orig
mount /dev/mtdblock2 /home/hik

You could also use TFTP, something like
TFTP -p -l mtdblock2_orig <IP address of TFTP server>

And the same for mtdblock0 & 1, though these don't need unmounted.
Then you can either at a later date 'cat' the mtdblock2_orig' back where it came from, or you can create new firmware using @wzhick really useful tool Hiktools to get a digicap.dav that the web GUI and TFTP recovery is happy with.
Also - make a backup copy of the NVR configuration, and the camera settings, via the maintenance menu, with the filename including the associated firmware version. You can't restore configurations across firmware versions.
That way - you can put the whole thing back exactly how it was before the firmware update if you ever need to do so.
