The Android 4.1 Jelly Bean OS has been announced by Google, and all developers attending the IO 2012 conference received a free Galaxy Nexus to test the new installment and see how its new features and functions are performing. Now, a developer that was at Google IO leaked the ROM for the Galaxy Nexus International variant and now another XDA developer managed to release the Jelly Bean ROM for the Verizon model of Galaxy Nexus.
Use the instructions listed in this post and you will learn how to properly update your Galaxy Nexus with the Jelly Bean Android 4.1 OS easily. The ROM brings support for all Android 4.1 features and calling, SMS, MMS, WiFi, 3G and 4G data, USB storage, Internal Storage and root/superuser is automatically installed along with ADB. This new ROM will work with rooted Gnex devices that are on Sprint. All the default Jelly Bean functions are working and there aren’t any bugs reported which means that this new ROM should work smoothly.
The WiFi signal on this Jelly Bean 4.1 is better that it was on the former ICS OS. Before we can start the updating process, you will need to read the guidelines and learn how to properly configure your device so that you’ll manage to flash the new ROM at your first attempt. Here’s what you need to know:
- install this Jelly Bean 4.1 ROM only on the Verizon variant of Galaxy Nexus. Do not attempt to install it on other phones because it won’t work and you might end up damaging them.
- The Verizon Galaxy Nexus device should be rooted and only afterwards you will be able to flash the new ROM. How-to root guide can be found here.
- Enable USB debugging on your phone and after that make sure that you recharge the phone’s battery so that it won’t power OFF during the update.
- In the tutorial guide you will find a step that tells you to wipe all phone data except for the internal and external sdcard contents. Make sure to move all the important files on one of these two storage spaces so that you won’t lose them. If you wish to be sure that no file will be lost, then you should move them to your computer and after the update is complete, you can simply use the USB cable to restore the files back on your phone.
- the applications, SMS, Call Logs info and the APN Settings can be backed up using these Android tools: AppBAK for Android apps backups | SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore.
- Sync your Phone Contacts with your Gmail account. Here’s a beginners guide that will help you backup all your contacts phone numbers.
- if you’re using an already rooted device, then you can use CWM Recovery, CWM manager, ROM manager or any other tool that has support for backing up the entire ROM that is currently running on your device. In case you don’t like how your Verizon Galaxy Nexus works with Jelly Bean then you will be able to restore the current firmware.
- install this update at your own risk and note that we cannot be blamed in case you damage your phone or it gets bricked. However, if you do brick the phone, then you’ll be forced to repeat the entire tutorial guide once again. Also, make sure that your phone is rooted and that CWM Recovery is installed on it.
Now that you’ve read and applied all the backup processes above, you should move to the tutorial guide and learn how to properly install the new Jelly Bean ROM on your Galaxy Nexus Verizon smartphone. Do not skip any of the steps I’ve listed in the tutorial. If you cannot apply the Android 4.1 firmware then you should use the comments field and ask for our help.

- Connect your phone to your PC and move the ROM package on your device’s internal / external sdcard.
- Power off the phone and after that you need to boot into CWM Recovery.
- When CWM Recovery loads its main screen, the first thing that you have to do is to select the ‘wipe data/ factory reset’ option. Confirm that you want to get rid of all these files.

Please note that in case your device takes over twenty minutes to complete the first boot, it means that your phone has been bricked or you didn’t install the ROM correctly and, you should remove the phone’s battery, then re-insert it and boot again into CWM Recovery.
