Key Points to Note

  • XXUFMB3 Omega Jelly Bean ROM and the instructions given in this guide are applicable to the international variant Galaxy S3 I9300 model only and will not work on any other device. Verify your device's model number by navigating to Settings > About Phone.
  • Verify that the correct USB drivers are installed for Galaxy S3 on your computer (download Samsung Galaxy S3 I9300 USB drivers).
  • Back up important data and settings on the phone to avoid data loss during firmware installation. It is recommended to use one of the custom recovery tools such as ClockworkMod (CWM) or TWRP for data backup, as it creates a complete image of the current phone set up. Avoid using either Samsung KIES or ROM manager, as they lack flexible options for data backup.
  • Make sure that USB Debugging mode is enabled on the phone by navigating to Settings > Developer Options (if the device is running Android 4.0 or later) or go to Settings > Applications > Development (if the phone is running Android 2.3 or earlier). Otherwise if the device is running Android 4.2, then do the following steps:
    • Go to Settings > About Phone
    • Scroll down to the bottom and select Build Number
    • Tap the Build Number seven times to unlock or reveal Developer Options under Settings. Then select the checkbox to enable USB Debugging mode under Settings > Developer Options.
  • Ensure that the device has at least 85 percent battery charge to prevent unexpected device shutdown (due to battery drain) during the ROM installation.
  • Verify that the device is factory unlocked and rooted with ClockworkMod (CWM) recovery installed on it.
  • Do a Dalvik Cache Wipe before exiting the Recovery mode.
  • Samsung KIES will not recognise your phone after installing this ROM, as it is a custom firmware release.
  • The instructions provided in this guide are meant for reference purpose only. IBTimes UK will not be held liable if the device is damaged or bricked during or after the custom ROM installation. Users must proceed at their own risk.
