If you own a Samsung Galaxy S5, you might be aware that the official Android 6.0 Marshmallow update from Samsung is coming to the device soon. However, we don’t know when exactly the update will be released, and the wait is making users impatient. However, you can now get Android Marshmallow earlier on your Galaxy S5 by installing CyanogenMod 13 (CM13) custom ROM.

The CM13 ROM is in its early phase and may still contain a few bugs. For example, some features like video recording or external storage might not work. So we expect the ROM to become more stable after a few updates from the CyanogenMod developer team. Please install the ROM at your own risk, because if done incorrectly, your device might get bricked.

  1. Download CM13 Marshmallow ROM and Gapps.

  3. Install the latest version of TWRP recovery in your device.
  4. Install the proper USB drivers for your phone in your computer.
  5. Charge your phone up to at least 80% and backup your data.

How to Install Android Marshmallow on Galaxy S5 through CM13 Custom ROM

  4. After the backup is complete, you need to wipe the data completely. Go back to the TWRP menu and select the Wipe button. Now tap on Advanced Wipe and select Dalvik Cache, System, Data, and Cache. Then swipe right to confirm the process.
  5. After the wipe is complete, return to the TWRP menu and tap the install option. Now navigate to the ROM file you copied in your device and select it.
  6. Finally, swipe right on the confirmation button and the installation will start.
