IOS Recovery


Last night while preparing routers for CCNP rack I was upgrading Cisco 2600 routers to support security, so I download 12.4 version ios and install on a router while installing I erase the existing ios and after erasing completion the router suddenly prompt “not enough memory” ………….Ohhhhhhhh. I reload the router, so it gives me prompt
Rommon >
Now no existing ios and stuck in this mode so after a short search “xmodem” command crossed my mind. Here are the steps to recover router ios.
Step # 1: Rommon > xmodem c2600-advsecurity9-mz.124-1a.bin
Now you will get message “Ready to receive the file”, after that follow step # 2
Step # 2: On Hyper-Terminal go to “Transfer” tab and select “Send File” so you will get another window as shown in the figure # a. Select the location of the IOS and then select “xmodem” from the drop down box and select receive.
Step#3: After this you will get the third window as shown in the figure # b. Select the path in the sending box where the image is placed, in my case the path and the image name is as given.
Sending: D:\tftp ok\ c2600-advsecurity9-mz.124-1a.bin
After that the receiving will be start, as shown in Figure # b.
I am hopeful this will be informative for you.
Enjoy!
