Is there a way to backup the entire firmeware and all installed softwares? My Nokia 770 broke, and I plan to buy another one. I would like to restore quickly all my config.

My 770 has only its screen broken; all works fine, but I can't see anything. My first idea was to use the flasher tool, but I didn't find how to do this. Is it possible? Or is there another USB-based solution that doesn't require any software installation?

Thanks,
