Update Sprint Galaxy Nexus with AOKP JB Build 5 custom ROM

The Sprint Galaxy Nexus has been included in the shortlist of devices that are supported by the latest AOKP JB ROM release. Use the instructions that I have listed in this tutorial and you will learn how to manually flash the AOKP JB 4.1.2 build 5 without too much trouble.

It is the first version of AOKP Jelly Bean that it is based on the Android 4.1.2 and you can get all its feature only by flashing the files in this post. The update shouldn’t take more than 5 minutes but, first thing that you have to do is to read the preparation guide. The prep guide will tell you how to backup important files and what other steps you need to take so that you’ll manage to flash the custom ROM from your first attempt.

There aren’t too many new features but the Build 5 of AOKP JB is pretty stable and there weren’t major bugs reported by users. However you might still find some other errors and that’s is why you should post them in the comments field. Now that you’ve read all these general instructions, I think that you should move to the next part of this post and learn how to correctly configure your Sprint Galaxy Nexus for the updating process. Here’s what you need to know:

  • The files in this article are only working with the Sprint variant of Galaxy Nexus. Don’t try to flash them on any other Android smartphone as you might end up bricking their firmware OS. Your Sprint Nexus has the model number L700 and this info can be found in the ‘About device’ menu by going through Settings app icon.
  • The Sprint Gnex you’re about to update should have its bootloader unlocked, it should be rooted and TWRP Recovery has to be flashed on it. All these can be found in this guide here. If your device already meets these requirements, then you can skip these extra actions.
  • Create a full NANDROID Backup file of your currently installed ROM. This file will be useful in case something goes wrong after the update and you cannot boot normally your smartphone.
  • TO backup applications, SMS, Call Logs and the APN Internet Settings use the following tools for Android devices: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android. Some of these will ask for root access and you should allow them to use it.
  • Sync your Contacts with the Gmail account. After the new ROM is installed you can easily restore all Contacts by simply entering the same Google Account.
  • Enable the USB Debugging option so that you’ll manage to connect to your device when moving the ROM files from PC to internal SDcard. Also remember to charge the device’s battery and this will not allow it to power off while you’re flashing the AOKP JB Build 5.
  • Remember that you’re installing these files at your own risk and we cannot be held responsible in case something goes wrong with your device in the updating process.
  • Apply all the steps that I have listed and make sure that you don’t skip any important steps. If you find troubles in completing this update, then you should ask for extra help in our comments field. We should be able to come up with a solution to your problems.
  • This is a guide that should be applied by advanced Android users and you should have a ROM backup prepared in case you brick the device.

These are all the guidelines you had to read and now you can proceed to the next part of this post and learn how to manually flash this AOKP Jelly Bean 4.1.2 firmware on your device.

How to install AOKP JB Build 5 on Sprint Galaxy Nexus:

  1. Download the custom ROM zip file from HERE. Place the file on desktop and don’t extract the contents comprised within.
  2. Download the Gapps file for Jelly Bean HERE. Don’t unzip.
  3. Connect the smartphone to PC and then move the files downloaded at steps above on its internal SD card. Disconnect the phone from computer when the files are successfully moved.
  4. Power off the Sprint Galaxy Nexus and then boot it into TWRP / CWM Recovery mode. Press ‘volume up’ + ‘volume down’ + ‘power’ buttons at the same time to boot into custom recovery mode and release these buttons when the screen flashes.
  5. Select ‘factory reset’ option and confirm this action. Note: In case you’re coming from a build 4 AOKP JB ROM then you can skip this step.
  6. Now you have to select ‘Install’ and then browse for the ‘AOKP JB Build 5’ zip. Confirm the installation. Repeat the same action in order to install the Gapps file.
  7. When bots the Google Apps and custom ROM zips have been installed you can return to the main recovery menu.
  8. Select ‘reboot system’ / ‘restart’ option. The first boot process into this new Android 4.1.2 AOKP ROM will begin and you should wait until all files are loaded and the phone shows its new homescreen.
  9. Enter the Google Account and then you’re ready to test this new release. That is it, you’ve successfully flashed the ROM.

If the first boot process takes over 10 minutes to load or in case the smartphone enters a boot loop, then you have to power it off, as the ROM wasn’t installed and you should repeat the entire tutorial once again starting with step 4.

In case you’re still having troubles in installing this update, then you should leave a detailed comment in our comments section and we willtry to come up with a solution. Remember that in case you retry to install this ROM, then you will need to apply step 5 even if you’re running the AOKP JB Build 4 as that will surely fix your problems.
