The original Galaxy Nexus (I9250) got it last official update with Android 4.3 Jelly Bean, but if you’re looking to get Android 4.4.2 KitKat on your aging device, the Paranoid Android team is more than happy to oblige.
This guide will help you install the Paranoid Android AOSPA 4.0 Beta 3 ROM based on Android 4.4.2 KitKat on the Galaxy Note 3. As always, Android stray assumes no liability for the firmware installation. Proceed with caution.
Before Getting Started
Before you get started, make sure that your Galaxy Nexus is the I9250 model. Flashing this ROM onto any other device will most probably result in a bricked phone.
Your Galaxy Nexus must be unlocked, rooted and with a recovery utility like ClockworkMod installed.
As always, you want to backup your device and charge it to at least 80 percent. Finally, enable USB Debugging mode by navigating to Settings -> Developer Options.
