yea i get that issue once every blue moon but its the active sync connection disables and then trys to reconnect but not in time so hence error. its a connection error you got, right?

normally manually enter bootloader then when you see serial then connect, wait for usb to show then start ruu works for me. there was once nothing worked but sd flash. then i would put stock rom on sd and flash via card method and that always seemed to work.

if that wasnt it...care to share how you solved your prob?
