Hikvision ERI-K216-P16 – Bound to Previous User, TFTP Update Fails

• Is there any technical way to re-flash or unbind this model?
• Or is the binding permanent unless Hikvision support removes it (which they likely won’t, since I’m not the original owner)?
• Has anyone managed to bypass this error when using TFTP with this model?

Hi everyone,


I recently bought a Hikvision ERI-K216-P16 NVR second-hand (eBay purchase). Unfortunately, it turns out the device is still bound to the previous owner’s Hik-Connect account. The seller cannot help me unbind it.


I tried using the TFTP method to re-flash the firmware, hoping it would reset the binding. However, the process fails with the following error:
econet vision av2000 failure

At this point I’m stuck:

• Is there any technical way to re-flash or unbind this model?
• Or is the binding permanent unless Hikvision support removes it (which they likely won’t, since I’m not the original owner)?
• Has anyone managed to bypass this error when using TFTP with this model?

Any advice or shared experiences would be greatly appreciated.


Thanks!

That's not a process failure - it's actually a comment by the tftp updater tool that it had received a probe for ArecontVision devices.
This is something the NVR does on startup, and it uses a similar UDP probe to what the NVR uses looking for the tftp updater on bootup.

There are a couple of variables that could affect success -
The PC and NVR should each be connected to their own switch or router ports - direct connection is less likely to work.
The IP address the NVR is probing is set by a bootloader environment variable, and can vary.
Common values are 192.0.0.128 and 192.168.1.128
