The thing is, flashing will always be a touchy thing. Even if you flash your bios on your PC, till this day there is still a chance of rendering your system useless (bricking). They can add a bunch of fool proof methods to get around this but there is always the possibilty. But these devices run from their flash memory so that is the only way to update them, I have no problem as long as I know I have full battery life, the image has been fully tested, and I have followed all of the given directions.
