Update Galaxy S3 I9300 to Android 4.4 KitKat with CyanogenMod 11 ROM [GUIDE]
Update Galaxy S3 I9300 to Android 4.4 KitKat with CyanogenMod 11 ROM

Galaxy S3 I9300 users can finally enjoy new KitKat experience on their phones, thanks to the release of Android 4.4 based unofficial CyanogenMod 11 ROM by TeamDouche. Samsung is still pre-occupied with periodic Android 4.3 Jelly Bean updates for the Galaxy S3, while Google has already released its source code for Android 4.4 KitKat update.

Third-party Android developers have been constantly churning out new custom ROMs such as AOSP and CyanogenMod 11 in order to support Android 4.4 on most Jelly Bean devices. An official KitKat firmware update from Samsung for Galaxy S3 still seems a distant possibility, and hence the release of Android 4.4 CyanogenMod 11 ROM for the S3 gains precedence.

The unofficial build of CyanogenMod 11 ROM for Galaxy S3 is now available for installation via ClockworkMod (CWM) recovery, with due credit to XDA developers for uploading and sharing the firmware file (preview).

Interested users can follow our step-by-step guide to install Android 4.4 KitKat on Galaxy S3 I9300 using CyanogenMod 11 ROM. IBTimes UK reminds its readers that it will not be held liable for any device damage during or after firmware installation. Users are advised to proceed at their own risk.
