The screen gave out on my N800. Sometimes it won't show anything at all, other times it only shows alternating scan lines, other times the missing scan lines are flashing.

Since it's a couple of years old and long out of warranty, I elected to get a new N800 rather than send it in for repair. The problem that I have is how to transfer everything to the new device without laborously reinstalling everything.

I was hoping for some nice tool to flash from one to the other (preferably not involving the screen on the old one) but didn't see anything obvious.

I've already taken a tarball of the internal filesystem. Will it work to jailbreak the new one, get an ssh server going, kill off just about all processes except the ssh server, then untar? Is there a simpler way?
