If you want to know about all the latest features of AOKP Jelly Bean 4.2.2 then you should use this post here. Before starting the installation, read the following preparation instructions:

  • Use this post only with the Sprint variant of the Samsung Galaxy Nexus.
  • Do not try to update any other Galaxy Nexus devices using this tutorial, as you will brick them.
  • Your device has to be on an unlocked bootloader, it should be rooted and running a custom Recovery image like the CWM or TWRP.
  • Use the custom Recovery image to create a NANDROID backup of the ROM that is currently running on your device. This will set a restore point for your phone and it can be used later.
  • A factory reset will be required before installing the new ROM, which is why you need to know that the system partition will be wiped. All installed apps data will be lost, which is why you should check the Google Play Store for a tool that will help you backup applications data.
  • If you want to backup SMS, Call logs info or APN Internet Settings, then you can use some of these apps: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access will be required for some of these tools.
  • Sync the Contacts info with your Gmail account using the guide here.
  • Enable USB Debugging from Developer Options.
  • Make sure that the phone’s battery has enough power left before switching off.
  • This is a guide for more advanced users and, you should know that we cannot be held responsible in case something goes wrong like losing important data files or bricking the phone.
  • Don’t skip any steps listed below and ask for more help in comments if you cannot complete the tutorial.

These were all the guidelines that you had to go over before continuing to the next part of this post.
