So I downloaded and started the upgrade to .148 today. Got as far as through the backup and went black and my LED is flashing. I've never backed up info in Desktop Manager and don't use it too much so I'm kind of at a loss. Not even sure if I can re-install the old OS. Anyone have any ideas? When I plug it in USB-style to my PC the LED blinks for longer and it keeps connecting/disconnecting when the LED goes through it's blink. Where should I start?
