I've seen a few people say when they put the battery in it pushed a pin down or something. Check that. I remember one guy saying he used a little bit of something to keep it propped up.

It happened to me as well. You just have to push the pin back up and reinsert the battery.
Thanks guys! Appreciate all the inputs. My G3 is now working fine after i did the above!Sweet good to know when ever I get to order mine I'll have to remember it.
