So the Galaxy Nexus is out and you’re wondering how to crack the device clean open (not literally, of course) and get started with some custom ROMs, mods and more. Don’t look too much further than this post as everything you need (LTE and GSM owners alike) is right here.
Learn how to root the device here. Learn how to install a custom recovery on that rooted device here (GSM only for now). Learn how to unlock the bootloader here and start looking for some ROMs here (but read up on how to flash ROMs first) Oh, and if you somehow happen to need to go back to stock you’ll want the GSM and LTE factory images. Get it? Got it? Awesome.
Be sure to carefully read instructions at each link for each specific task. It’s imperative that you go in the order from root through to the ROMs if your device is still fully stock. And remember that no one holds any responsibility for anything that may happen to your phone but yourself. With that, happy flashing!
