When you hook phone up via usb cable, you need to select disk drive for this part.
your pc will recognize your phone as an external drive and ask what you want to do, open it to review files.
you need to put that file you downloaded on to the sd card. Just drag and drop it right onto the name of the card/drive. It will go ON your card but not IN any of the folders.
Then you are good. Tell the phone you want it to be in Charge Only mode and done, at that point. Then follow the guide.
great ...so then i do not need to do a factory reset like the rules on before rooting say?
