Hi Sunny,

If there is no IOS router will move to rommon and the only option left is to xmodem.

Here is the link for generic xmodem procedure

Re: Erased flash by mistake 1701.

Hi Sunny,

For xmodem you do not need any warrenty. But yes you have to download image from Cisco.com and for that you may need to have valid cco login.

Also if you have image already with you then you cn start xmodem procedure. The link which I posted in my previous post has step by step instructions for xmodem procedure.

HTH, if yes please rate the post.
