The Galaxy Note 3 was Samsung’s flagship phone in 2013, and it immediately became a huge hit among Android users because of its powerful processor, improved S Pen function, and excellent battery life. It’s still a great smartphone especially compared to mid-range and low-end devices, but it can’t be denied that the Note 3 is past its prime.

This is evidenced by the fact that it didn’t receive the Android 6.0.1 Marshmallow update. It was shipped with Android 4.3 Jelly Bean pre-installed in it, and it later became eligible for Android 4.4.2 KitKat and Android 5.0 Lollipop.

But, since it was already two years old when Marshmallow came out, it had already gone over Android’s 18-month support window and apparently was deemed to be ineligible for the update.

Still, many Galaxy Note 3 owners are waiting for Marshmallow to be available for their device. The chance of this happening is slim considering that Google is already rolling out Android 7.0 Nougat but, if you have a Note 3, don’t worry since there several ways to get the Marshmallow update.



One of these is to download the Unofficial CyanogenMod 13 custom ROM for the Samsung Galaxy Note 3. This was created by XDA Developer Morningstar, and it will allow your device to have the features that Android 6.0.1 brings.

Ready to start? Here are the steps you need to take:

  1. Check that your phone’s model number is either N9005 or N9002. The Unofficial CyanogenMod 13 works only on Galaxy Note 3 variants that have the Qualcomm Snapdragon 800 processor, which are the two models above.
  1. Ensure that your smartphone has at least 80 percent battery life. Installing the custom ROM can take some time and, if your device powers off in the middle of the process, it can get bricked.
  1. Remember that installing a custom ROM comes with risks. It can void your warranty, expose you to security threats, and even brick your phone. It’s important to be aware of these dangers before proceeding with the installation.
  1. Create a backup of your data. Downloading and installing a custom ROM can make you lose your contacts, messages, photos, videos, and other important files, so you need to back them up before doing anything else. You can use TWRP Recovery, ClockworkMod Recovery, or any other similar tool.
  1. Download the Zip file and the Google Apps (GApps) file for the custom ROM on your computer, then transfer them to your phone’s internal memory through micro USB.
  1. Press the Home, Power, and Volume up buttons together to enter recovery mode. Use long press until you see the Samsung logo come up.
  1. Do a factory reset. If you’re using TWRP, you can do this by choosing “Wipe” when you enter recovery mode then swiping to proceed with this action.
  1. Install the custom ROM Zip file you downloaded earlier. Again, if you’re using TWRP, you’ll need to swipe to confirm this action.
  1. Flash the GApps file. If you’re not sure how to do this, head to da-developers.com/download-google-apps-gapps to know what steps to take.
  1. Reboot your device.

That’s it! By taking these steps, you can enjoy Android Marshmallow and its features on your Samsung Galaxy Note 3. To learn more about this process, you can read this guide from Root My Galaxy.
