  • The AOSB KitKat ROM and the instructions given in this guide are meant for the Galaxy Nexus I9250 model only. Verify device model number by navigating to Settings > About Phone.
  • Back up data and settings using a recommended custom recovery tool, like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup. In Recovery, choose Backup and Restore and tap Backup.
  • Verify correct USB drivers for the phone are installed on the computer (download Galaxy Nexus I9250 USB drivers).

Then select the checkbox to enable USB debugging mode under Settings > Developer Options.
  • Make sure the phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
  • Ensure the device is unlocked (not locked to a specific carrier) and rooted with latest ClockworkMod (CWM) Recovery (v6.0.4.5 or above) installed. Alternatively, install CyanogenMod 10.2 Nightly which includes CWM recovery v6.0.4.5.If you are installing the CWM recovery for the first time, check out the video tutorial below, courtesy of The Android Soul:
  • If the device is stuck at booting or experiencing boot loop issues, perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
  • Allow newly installed ROM to stabilise for five minutes before you start working on it.
