ROMMON warning message "Cookie information is corrupt"

[astrand]

Hi,

I get the warning message "WARNING: Cookie information is corrupt" on one of our routers (Cisco 827).

It boots up in rommon and I am not able to boot up IOS. I have tried to install a new image using TFTP, but I get the same error message when I try the tftpdnld command from rommon.

Has anyone got any ideas how to fix this? Any help would be very appreciated!

Regards,

Harald

I think it might be a problem with device, check with your vendor to replace the device.
