As reported by Droid-Life, you’ll need to know how to use ADB. You also need to be comfortable with the rooting process and know how to make Titanium backups of your phone. It’s an 11-step process that is detailed on xda-developers. You must follow it carefully, even the part about downloading and installing a Chinese binary. Now that root is out the way, it is on to bigger and better things like unlocking and custom ROMS for the handset. Give it a little more time and the G2 may turn out to be a fun phone for hackers to tinker with.
