An easier method would be to:
1 - Search xda for towelroot and download and Install.
2 - Search for autorec and download and install that as well.
3 - Open towelroot app and click on "make it rain" .
4 - Download Super from the PlayStore and install.
5 - Open the autorec app and let it so it's thing.
After this you should have a rooted G2 with TWRP recovery. Sorry for not having the links off hand, I'm on Tapatalk, but the two apps should be easy to find.
