Update dashboard version

I'm trying to update my console's dashboard version so I'm thinking of asking here. I found a video on Youtube where to update I need flash something in my console using Flash360. I've watched the whole procedure but I can't help to think that it's kind of risky. Can I know whether the process(flashing) is reversible, will not cause any trouble if not done right or done halfway?
