Dahua NVR 6000 incorrect firmware

[ardiross]

I have a Dahua NVR 6000 and I accidentally flashed the lite version of the firmware on the unit and now I can't flash it with the full version. It just keeps saying invalid upgrade file. Does anyone have any ideas?

Does anyone have any ideas?

A couple of useful recovery posts from @cor35vet
Dahua IPC unbricking / recovery over serial UART and TFTP
Dahua IPC EASY unbricking / recovery over TFTP
And my own recent similar experience:
Bricked Dahua NVR DH-NVR5208

OUCH!! I have never dealt with a 6000 but I have the same issue with other Dahua NVR's after "UPGRADING" only to find out that yes the firmware number increased but lost functions, to this day ...and I'm not alone, I can not find a fix for this issue. I will say Dahua has as of recent addressed this issue with auto firmware updates, like you would see on Routers and computers. Did you contact your re-seller you bought it from ?
