Here’s a really fast and smooth Jelly Bean ROM you will appreciate, the Codename JB ROM!
The Codename Jelly Bean ROM comes out of the box with Android 4.1.1 and everything working. Not only that, as we have seen with Codename ICS ROM, the Jelly Bean version also brings you a ton of UI customizations. Of course, my favorite feature about the ROM is that it’s running Jelly Bean, project butter seems to whisk past any ICS ROMs I’ve tried, especially Touchwiz ICS ROMs.
You will definitely not be disappointed with speed or battery life on this ROM and
