Update Galaxy S3 GT-I9300 to Android 4.4 KitKat via OmniROM

Galaxy S3 GT-I9300 users can now enjoy a fully functional and bug-free nightly build of Android 4.4 KitKat based OmniROM custom ROM, thanks to the industrious efforts of Xplodwild, Chainfire and Dees_troy in releasing this ROM.

The OmniROM is based on original Android Open Source Project (AOSP) with a handful of new features including seamless incoming call notification window, flappable quick settings, multi-window, multi-workspace modes, visual improvements for the whole UI, DSP Manage enhancements and per-app permission control in Settings.

Interested Galaxy S3 users can go ahead and install this ROM on their phones by following our step-by-step guide provided below. IBTimes UK reminds its readers that it will not be held liable for any damage to device during or after firmware installation. Users are advised to proceed at their own risk.

Pre-requisites

  • The OmniROM and the instructions given in this guide are meant for the Galaxy S3 GT-I9300 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 S3 GT-I9300 USB drivers).
  • Ensure USB debugging mode is enabled on the phone, by navigating to Settings > Developer Options (NOTE: Tap the phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings.) 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) installed. 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.
