Those who wish to update their Galaxy S4 to Flyme OS ROM featuring Android 4.4.4, may follow the installation guide.

IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Before following the installation guide, users are advised to verify their devices meet the following requirements.


  • Install USB Drivers for Galaxy S4 to transfer files between the Android device and the computer.
  • Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it.
  • As the tutorial might wipe out all data of the phone, create a backup. If the device has any custom recovery such as ClockworkMod or TWRP then backup data using the same.
  • If the Android phone powers off due to lack of battery during the process, it could damage the device. Therefore, the Galaxy S3 should have above 80% battery charge.
  • The phone should be rooted and have the latest version of ClockworkMod recovery.
  • Android 4.4.4 Flyme OS ROM works only with Samsung Galaxy S4 GT-I9500. As applying this to any incorrect variant might brick the device, verify the model number of Galaxy S4 by navigating to Settings>> About phone>> Model number.
  • After flashing the ROM if the device gets stuck on Booting animation or experience boot loop then perform wipe cache partition and wipe dalvik cache for a few times before rebooting the device.
  • Once the ROM is installed, users are advised to give 10 minutes to the ROM after the device boots up for the first time for better user experience.
