The developer of the RazrUtility has reported that the Motorola drivers have been changed recently (changed after the 1.7 version was released) and that is what is causing the problem. I haven't seen a fix or different version of the utility as of yet. The developer is a very reliable guy, I'm sure he's working hard at developing a version of this utility that will work with the new Motorola drivers.I'm on OTA 211 and not having any luck on getting this to work either.
