Yea, I had to charge up to update, used the pc updater. I flashed back to stock first as well, I got an error when I tried to update through the phone while it was rooted.
I tried the spectrum ICS root and also the optimus G JB (ZV9-JB-Root) batch files. No luck, get permission denied with both. Gonna call it quits for tonight, have to work early. I hope we can come up with a way to root this thing
I wonder if Foxfi works for wireless tethering, I'll give that a try tomorrow, but it's going to suck not having titanium backup if we can't root.
