This all worked (util 1.6) on my last razr but I had to get a factory replacement and I just can't get it working for some reason.
Just keep on trying, my friend. It's probably going to end up being some little something you're forgetting or overlooking or, simply haven't realized you need to do yet. That's what happened with me. Once it worked though, it worked flawlessly.
Edit: It can't hurt to run as admin but, it shouldn't be necessary. I only say this because I'm still trying to think of another possible problem he could be having.
