I am working in a lab environment with 3 1760's. I had some problems keeping my router secure because of people using password recovery to change my configuration. I decided to disable password-recovery which disables ROMMON completely. The same day I upgraded the IOS in one of the 1760's to run voice without even checking if my hardware could support the new IOS. When I reloaded, it couldn't load the image because I didn't have enough RAM. Now the router won't load up and I can't get into ROMMON to change the image. Does anyone have any ideas what to do? I cannot upgrade the RAM or Flash, but I can't switch between the 3 1760's. I tried switching the flash cards but apparently the no service password-recovery command saves onto the flash and none of my 1760's has enough RAM to load the image to change it.
