Pls I have a little issue with 2600XL router. I just upgraded the IOS image from c2600-ipbase-mz.123-6f to c2600-ipbasek9-mz.124-12.Upon reloading, it failed to boot properly. I quickly reloaded the initial image and then restarted it, the problem persisted. Right now, it keeps booting into the rommon mode and fails to boot properly. Please how can I resolve this, as I need to use the router soon.
