I have tried to update the device without a back-up and everything SEEMED to be fine BUT ... after the update, when I start it, it only shows a white cross on a red dot. Furthermore, when I have checked the content of the drive in the laptop, it seems to have been deleted!!! HELP!! I do not have a back-up, I have nothing! and now the device is dead and there isn't a reset button on it or i could not find it.
