Custom menu in camera missing nvr dahua DHI-NVR1108HS-S3/H

[bangkawarah]

I have problem, on dahua nvr DHI-NVR1108HS-S3/H
there are no custom menus
I've changed several firmwares, the results are the same, the custom menu doesn't appear...
Is there a solution if you want to restore the custom menu?
cheers..
