Install Android 4.1 Jelly Bean ROM On Galaxy Nexus GSM

The Galaxy Nexus GSM fixates itself on some Android 4.1 Jelly Bean goodness! Just a while back Google released an OTA for the GSM based Tajku Galaxy Nexus that were handed to the conference attendees at Google I/O. Well, the idea was to keep the release exclusive, but we’re talking Android, and that fact alone, is enough to guarantee that Jelly Bean will be ripped out of one of those devices and released onto the internet. Well, guess what? XDA-Developers forum member PTzero has made that happen and the release went viral on the internet in no time. However, not to undermine PTzero’s effort, the release was actually an update to the Tajku devices running the IMM30B build and only a handful of people actually had that going for them. That said, those who did have that build, had to flash the update via Fastboot and some users were looking to flash the IMM30B build just so they can flash this update on their phone. However, all of this was too complicated and too sketchy where you were almost shooting in the dark. So while some dismayed and some eagerly awaited for a proper zip package they could flash, it has finally happened and that too, at quite some speed. Galaxy Nexus GSM users are now looking at not one, but three Android 4.1 Jelly Bean based custom ROMs, including a stock ROM, ready to be flashed on any Galaxy Nexus GSM device, without the worry about the current build you’re on.

Been living under a rock? I can help you come up to speed with what the new Jelly Bean OS offers. See our guide summarizing the new and improved features of Android 4.1 Jelly Bean.

Stock and Rooted, MCR – Jelly Bean, and Jelly Belly v.1 w/AwesomeBeats make up the ROMs available for the Galaxy Nexus at the time I write this. There’s a good chance that you have stumbled here and are itching to get Jelly Bean up and running on your device but are not rooted, not custom recovery installed and well, you probably have no clue on how to do so. Well, let me take you through a comprehensive tutorial on how to install Jelly Bean on your Galaxy Nexus GSM.
