Ok first of all WRITING IN ALL BOLD WILL NOT GET YOU HELP ANY FASTER. Only annoy people.
IOS Installation Error Most likely using an old or incorrect IOS, missing an IOS, or the IOS you're trying to install cannot be installed on top of another.
Q. How do I fix this error?
A. Fix it by installing a newer IOS 249 than the one you already have (if you don't have it, try installing it). If you still get this error, fix it the same way as Error 2011.
Most likely installed incorrect or out of date IOS.
