It is a hardware failure. The same thing happened to my girlfriend's LG G2 after a couple weeks and we had to return it. The second G2 she got has worked fine ever since.
But hey, that's the G2, not the Optimus G, so it maybe different. I've just noticed more than the normal amount of hardware failures on some LG models. My first LG Optimus G didn't get LTE, and (long story) after accidentally having the phone fall off the top of my car and shattering the back gorilla glass into a million pieces, I bought another LG Optimus G. The _second_ LGOG did get LTE right out of the box! Go figure! Same exact model, same carrier, even the same SIM. So there was obviously something wrong with the LTE radio of the first one right when I got it (I never returned it because I never actually read the specs to find I was supposed to be getting LTE all along, lol).
