Cisco 1841 ISR and SDM

When I attempted to log into a Cisco 1841 ISR, the SDM banner motd showed that I had to use the default username and password cisco to access the router, then change them. I changed the username and password and saved the updates to startup-config. I wanted to remove the requirement for a username and password at console login so and I went back into config and issued a no username' command for the username I added  and saved the updates to startup-config. I logged out and couldn't log back in. I attempted a password recovery by breaking the boot with a confreg 0x2142 , and rebooted the router , and I am still locked out. I am guessing I could copy the startup-config to from another router to removable flash, put that flash in the router I screwed up , and boot from flash ? Any tips would be most welcomed. Thanks
