Hi Sergio,
Thanks for checking up on this! I still need to try one last thing and that's the recovery using the dfu-util and xfstk, but I haven't had time to set up a linux machine yet. I have a virtual one, but it's 64 bit and from reading one of the other threads that's likely not gonna work with xfstk.
When I know more I'll let you all know here, there is just a little too much at work at the moment, so no time to play with Edison ;-)
