Android 4.1, Jelly Bean, was just announced some 24 hours ago, and already the Android community has it up and running on several Galaxy Nexus models. So you say you want to give it a go for yourself? Here's what you need to know:
Keep in mind that when doing these kinds of things, you risk breaking your phone. And information is constantly updating, so be sure to refer back to the original source before flashing anything. Now that we've got that out of the way, if you have a GSM Galaxy Nexus, it's as simple as flashing a couple files in ClockWork Mod.
For the first method, there's the actual ROM file, a root fix and a ClockWork flashable radio, all found in this XDA post. Once you flash all three, you should be running a fully rooted stock Galaxy Nexus set to take on your GSM network of choice. Problems with the build have been minimal (from what I can tell), but this is still a developer preview. The full Jelly Bean experience will be available in mid-July, and there may be some minor adjustments.
The second GSM method (and the one I will probably be trying myself sometime this evening) uses a highly customized flashable ROM from Paul O'Brien, AKA MoDaCo. Paul's method is incredibly simple. From his post:
- Download the zip file of your choice from the XDA thread (or the online kitchen) and copy to your the internal sd card (/sdcard/)
- Restart your device in recovery mode
- PERFORM A NANDROID BACKUP FROM THE MENU
- Select the option to apply an update zip, and select the zip file you copied to the internal sd card!
Pretty easy, right? To use Paul's ROM, head on over to XDA.
Verizon Galaxy Nexus owners, consider yourselves very luck. Even though the original update was released for the "takju" developer/Google Play Galaxy Nexus, some developers over on RootzWiki have reworked the update into a ClockWork flashable file that works with 4G LTE. In fact, you even have a choice. Both TeamLiquid and TeamVanir
