I just bought a Sprint Optimus G today. The first thing I was going to do when I got it home was root it and investigate good ROMs. In the developer options, the check box for USB debugging is grayed out and I cannot select it. I have rooted android devices before. I'm running cyanogenmod on my Nexus 7. I had seen that people were able to root and unlock this phone which was the final thing that let me make up my mind to buy it. Any suggestions or am I just completely out of luck?
