ok, so i am trying to root my galaxy nexus, however, i dont seem to be having much luck with any of the guides i have been looking at...i spent most of yesterday afternoon trying to setup my computer to use wugfresh's tool, but had all kinds of issues when trying to configure the drivers....is there an app i can get from the app store to root my phone? or a good tried and true tutorial i can follow that isnt too complex?
