Bricked NVR!

[James-T 0]

Hi

I have a Zxtech 4 ch NVR which failed a firmware update and is now bricked.

(The first 2 updates were great).

It has power and I can connect to it directly via a PC (not via the router) and it has an IP address (not on the router) - is there a way to install the previous firmware?

The circuit board says NVR3520D-V1.1 and it looks remarkably similar to the Hikvision version.

Any ideas!?

Thanks
