SuperNexus JB ROM for AT&T Galaxy S2 SGH-i777! [Build 5]
Striving to make a “pure” Google Nexus ROM, XDA user Faryaab brings us SuperNexus Jelly Bean ROM, this time with everything working out of the box including bluetooth (which wasn’t working in Build 2). I am glad to say that this is finally stable Jelly Bean you can install on your AT&T Galaxy S2 SGH-i777.
