MIUI has proven to be a highly desirable aftermarket firmware among the developer community, and today marks the initial release of Jelly Bean builds for the Galaxy Nexus, Nexus 7 and Nexus S. Currently, the ROMs contain no major bugs, which is good news considering previous Ice Cream Sandwich builds offered less than ideal functionality. The massive changelog offers an in-depth look at the the backend changes that had to be made to support the bump to Android 4.1. Fresh features include a revamped video player UI, a new contact manager and hundreds of optimizations. You can read the official instructions and download your ROM after the break.
- Download the ROM to your device’s internal storage.
