I've spent quite a bit of time customizing my Nokia 770 to my liking. I've installed all the programs I need (including some with dpkg); I have rearranged the entire /etc/others-menu directory to reflect my most commonly used programs; I've added application icons for starting/stopping the SSH server and for enabling/disabling MMC swap.

With all this root tweaking, I'm bound to destroy something eventually. Are there any good ways of extracting the entire contents of the Nokia 770's internal flash into a file (ideally onto my PC over USB into a file that could be given to the flasher utility).

Something like the opposite of flasher, is what I'm looking for.

If there isn't, I'll have to settle for a dd or tar solution.

Anybody have any ideas for backing up the Nokia 770's entire internal flash?
