I want this flip case for my Note 3.
If you want JB go here: http://galaxynexusroot.com/
I'm sure there are other great sites but this is the one I used. I had my GNex unlocked, rooted and running JB on Frankos kernel within 3 hours of getting it home. If a dumb-ass like me can do it, anyone can.
The only caveat is that I had ADB running prior to getting my Nexus from tweaking my Bionic.
Read first. There's great videos to help clarify.
If you have a Nexus, this is what it was made to do.
