The Optimus 4X HD was a really well built device with great 2012 specifications released in the middle of last year. But it had some severe software problems, and was locked down so tight nobody could do anything hackish to try and fix them. Glaring software bugs and lack of third-party support is a recipe for a dud in the Android community, and the phone languished away with very few folks paying any attention to it.
Today, all that changes. Jelly Bean has been leaked, the bootloader has been unlocked, and there's already a ClockworkMod recovery built and ready to go. I warn you -- it's not as straight forward as some of the things you'll see, and you'll want to read, read, and read some more before you get started.
