Galaxy Nexus GT-I9250 Gets Slim Bean Based Android 4.1.1 Jelly Bean Update [How to Install]
Slim Bean ROM is the follow-up ROM to the immensely popular Slim ICS series of ROMs, which is now available for international Galaxy Nexus (GT-I9250) and the Verizon variant (SCH-I515) models.

Slimmed down custom ROMs are in great demand among Android smartphone users, thanks to their lightweight design and user-friendly interface. Android users can now relish more storage space on their Android phones. The ROM size is hardly 80 to 90 MB, and includes custom home launcher, besides adding smaller DPI value for higher density of text. Thus it offers enhanced image clarity for a seamless Android experience.

Thanks to XDA Developers member krarvind, the follow-up ROM to the immensely popular Slim ICS series of ROMs is now available for the international Galaxy Nexus (GT-I9250) and the Verizon variant (SCH-I515) models. As the Slim Bean ROM is still in its nascent stages of development, a few minor bugs like slow GPS connection are expected to exist. Despite the known bugs, the software is expected to work fine with all other updated features, while the developers have assured a fix for these bugs very soon.
