I know no idea. I used the other method. Here's the link to the thread: linky
. There's a video to walk you through the process. The Tool will install the drivers needed. So, I would suggest removing any drivers you have installed regarding the phone. If everything goes well, it shouldn't take longer than fifteen minutes. I had to do it twice. And the tool that you only need once be used free.
