So how does this work? I just bought an N810 off of ebay and all that came with it was the unit itself, 1 stylus, the battery inside the unit and the wall power charging adapter; nothing else. Whoever the guy was, he'd set it up with 2 separate boot-able partitions, each with it's own desktop and no ability to access the other or any programs installed on the other. The one listed on the start-up menu listed as 'flash' was the one I was using, but it suddenly started crashing and restarting the system as soon as it finished starting up. I want to erase everything on the whole unit and start over from scratch; is there a simple way to do this and will I have to get the USB cord needed for the unit? Can this be done off of a Windows 7 system?
