how do you upgrade a 4700 from the bootstrap?

I tried upgrading our 4700 router, and it all seemed to be fine until I rebooted, I get the following errors when I reload:

I can't find a way to load a new image from here, or from the rommon, I've booted into the rommon and don't get an xmodem command. I'm at a loss as to how to do anything, does anyone have any ideas? Thanks

Re: how do you upgrade a 4700 from the bootstrap?

From the Router(boot)> prompt, you

should be able to go into enable mode

and "copy tftp flash" the image

again.
