Samsung released the Android 6.0.1 Marshmallow update to the Galaxy Note 4 earlier in the year.

However, the official update comes with TouchWiz UI containing many useless bloat-wares. They tend to affect the performance of the device. Those Galaxy Note 4 users who are not satisfied with the current update can try installing X-ROM firmware.

It comes with massive 1.38GB in size and boasts of all the new Galaxy Note7 applications, themes, wallpapers, performance tweaks, battery life improvements and numerous other value-added features to enhance user-experience.

Prerequisites (Things to remember before installing the custom ROM):

  1. This new Android 6.0 Marshmallow X-Rom custom firmware has to be installed on the Samsung Galaxy Note 4 (SM- 910F) LTE model with Snapdragon chipset only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
  2. Make sure the device is rooted before going forward for custom ROM installation
  3. Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  4. Make sure the PC has USB driver software, or else the device (Galaxy Note 4) will not be recognised by the computer.
  5. Make sure the device has more than 80% battery, or else there is chance of the smartphone getting temporarily bricked if the installation process is interrupted midway.
  6. Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
