Yesterday at Google I/O when Google announced Android 4.1 Jelly Bean, they also handed out Galaxy Nexus handsets to all developers in attendance. These handsets were special developer editions, and actually got an OTA update to Android 4.1 Jelly Bean as soon as they were powered on. Fortunately, some of those in attendance fortunate enough to get these Jelly Bean devices have already extracted the update files and posted them on the RootzWiki Android development forum to allow the rest of us to get a taste of the latest version of Google’s OS.

As you would expect, the build isn’t completely stable, nor is it for everyone. It was released by Google to be a test build for developers, and could include all manner of bugs and problems. You will need a rooted Galaxy Nexus if you want to try the Jelly Bean leak, and although the build shouldn’t destroy your phone, bad things are possible so I would suggest at least making a Nandroid backup. The build is originally from the GSM Nexus, but if you have a Verizon device then there is an extra radio which you can flash that should make everything work properly.

You can get the Jelly Bean developer preview leak in a Nandroid backup through the source link below, which you can then restore on your phone using whatever recovery software you prefer. A ClockWorkMod Recovery flashable .zip file is in the works, but isn’t out just yet. If you don’t know what those things are, then you probably shouldn’t be trying to install the update, and even if you do know what you are doing, please exercise caution. The “leaked” developer build is officially from Google and could be quite interesting to try out, just as long as you don’t break your device.
