A new custom ROM, dubbed CM11 Milestone 11, is now available to help users of the Samsung Galaxy S4 LTE, with the model number GT-I9505, to update their devices to Android 4.4.4 KitKat. The custom ROM, which is considered a stable build, brings more features in addition to the ones found on the official version of the firmware.

The CM11 Milestone 11 ROM includes several improvements, such as a bug fix related to “switch to last app” functionality in Recent view, APN updates for various regions, support for all available slow shutter speeds and various security updates.

The custom ROM for the Galaxy S4 LTE is not an official release by Samsung, so users need to root their device before flashing the firmware. The device is also required to have custom recovery such as ClockworkMod to flash the ROM zip.

Here are some aspects that users should know before flashing the ROM:

  • Users must ensure proper back-up for personal data on the phone
  • The handset should have at least 80 percent battery power
  • USB drivers for the Galaxy S4 must be installed on the computer
  • USB Debugging must be enabled on the phone
  • The tutorial is only for the Samsung Galaxy S4 LTE (GT-I9505)

Note: International Business Times cannot be held responsible if anything goes wrong. Users should proceed at their own risk.
