ask us what you don't understand and we'll explain. there is no all-in-one guide for gecko os really, it doesn't do a whole lot to begin with although what it does do is install IOS files needed by a game that might be blackscreening on you that you have the update blocked for.
I mean, what do you wanna know? and not trying to be a dick, but why are you giving geckoOS to someone who doesn't have an idea on how to use it, let alone you? Why not give him things he can understand?
