If it's just fully erased (full of FF in all locations), as it can be on quite old cameras, it will be fine. The program in the newer firmware recognises that.this one has 5.2.5 and have problem with empty mtd1.
Excellent! Well done for getting there, and for sharing.Thank you for cooperation, all of 8 cams are updated to 5.4.5 and it seems, that everything is ok.
Well, the -NI version should be updateable. Is that how it was sold, do you recall?Is possible to do something with CH NVR DS-7616NI-E2?
I'd say that the -NI does suggest so.It is upgradeable?
On the early firmware (3.0.8) telnet was still available and enabled in the Busybox, but they quickly removed it in later revisions.Is some way, which I can look (for example via SSH) if is with NVR manipulated?

Depending on how that has been done, getHardInfo may not tell the whole truth. But the -NI is probably a more reliable indicator.But the risk would be if it is a CN NVR running a seller-installed 'hacked to English' firmware which masquerades the language,
Example - one of my CN 7816 NVRs that shows both languages depending on where you look, due to tweaked firmware.I saw language=1 and I risked it
