@mint So the odds of actual data-recovery are slim? I mean, you can dump the image, right? (It is too late for this for now, but if you've got ssh access to it, it's good to have /usr/local/bin/dnsmasq-announce do something that, somewhere down the chain of events, ends up executing an rsync when your phone arrives on wifi after being offline a while. I had something like that for my N900 and later my HP Veer.)
