hi,

hi,

you should open that router in rommon mode ( use "break" button in keyboard). and change confreg number.

Default value is 0x2102 . new value is 0x2142

And reboot.

Then router will open with no configuration. (Because 0x2142 ignore nvram and startup-config is stored in nvram). 

After you should copy config files in flash to running config and set new username and password.

That link include other confreg values.
