There is a option to upgrade the IOS from rommon mode. Upgrade the correct IOS via rommon mode and boot the switch via this new IOS.

I too faced the same issue and we have upgraded the IOS via rommon, and got success.

To upgrade the IOS in rommon mode just go through this below URL

This is what I did , but as I mentioned I do not have a saved image in disk 0 or disk 1. it was done by a newbie and ZI have to fix it

when I do set the boot path it gives me an option to reset -s and then loads from the old image

thanks for ur reply
