I'm trying to upgrade IOS in Cisco 7204VXR.
Actually, it's working c7200-ik9s-mz.123-5a. I've tried to upgrade to c7200-ik9s-mz.124-23, and I've change boot system to disk2:c7200-ik9s-mz.124-23.bin, and other IOS, but everytime I restart the router, 7204VXR start with old IOS.
Also, I'm tried to delete old IOS, but router cannot load any new IOS.
Can you help me?
