Are you still using the Samsung Galaxy Note 4 on a daily basis or as a backup device? Well, how about updating it to Android 9.0 Pie OS? Yes, that can happen and no, we’re not talking about an official Samsung roll out. So, what’s left? Of course, a custom ROM alternative, which is now bringing the Lineage OS 16 platform into our attention. Thus, in that regard during this tutorial you can learn how to update your Galaxy Note 4 to custom Android 9.0 Pie with the help of the LineageOS 16 firmware.

Lineage OS 16 for Samsung Galaxy Note 4 is brought by xda senior member ripee so we must thank him for this unofficial Android 9.0 Pie update opportunity. We’re here only to detail the advantages of using this custom ROM, this risks that are implied, the essential pre-requisites and the flashing steps that must be followed in the end.

This Lineage OS build is stable and comes with a customized version of Android Pie. That’s why the Pie functionality will smoothly run on your Galaxy Note 4. Basically, you won’t be experiencing any software related issues while using this custom ROM on your smartphone. Actually, you will be able to apply certain tweaks in order to bump speeds, upgrade battery life and improve general performance. And, not to mention, this is a great way in which you can test the latest Android features, apps and capabilities while using a device that isn’t receiving Samsung’s official support anymore.

Of course, setting up an unofficial update will trip Samsung KNOX. That’s not quite relevant because losing the warranty on the Galaxy Note 4 shouldn’t influence your decision on whether to keep using the stock OS or choosing the Lineage OS 16 custom ROM instead. Anyway, everything can be restored back to factory state when you choose to use Odin for manually reinstalling the official Android software on your phone.

As you will observe, a full wipe is required during the update operation. Shortly, you will have to make a hard reset and clear app data cache as otherwise the new OS won’t run properly. Therefore, take care of your personal data such as contacts, call logs, texts, images, videos, audio files, market apps, EFS folder, internet settings, calendar info, saved passwords, IMEI / NVRAM data and similar other packages that might still be required in the end. Remember, there are built-in cloud storage services pre-loaded on your Samsung Galaxy Note 4 but you can anytime choose to use other dedicated backup and restore solutions instead: sync files with your Google account, save data on external storage devices or download backup and restore tools from Google Play.

Making a Nandroid backup is more than recommended considering the fact that Lineage OS will be used – when a custom ROM is installed you might find out that it isn’t running as you expected. So, in that case you will most likely want to go back to stock. Well, you can easily do so by using the Nandroid backup package – this particular backup operation will save the current Android OS that runs on your Samsung branded device.

You can set up Lineage OS 16 on your Samsung Galaxy Note 4 only if you first gain root access on your phone – root must be ensured as otherwise the custom Android 9.0 Pie based ROM cannot access and then modify built-in features, apps and settings. And, a custom recovery image must be used during the update process – the custom ROM can be applied only from TWRP recovery, or from a similar other custom recovery software.

You’ll have to download the update package and compatible Google Apps (aren’t included in the update file by the way) on a computer and later you will have to connect your smartphone with your PC – make sure that you can do all that.

On your Note 4 you must access Developer Options from Settings; if you can’t go to About Phone and tap repeatedly on Built Number – keep tapping until the ‘you are a developer’ message appears. Afterwards, from Developer Options check the USB Debugging feature.

Charge your Android device before starting the update process. It’s important to make sure that there is enough power left – we recommend more than 50%; otherwise plug in the charger before doing anything else. When the power is low your handset can get turned off in the middle of the flashing procedure and then software related problems can be caused – so be careful and try not to soft brick your Galaxy Note 4 while installing the Lineage OS 16 custom ROM.

  1. Open your computer and run your web browser – access this page and download the Lineage OS 16 ROM package; then access this page and download compatible Google Apps for your Note 4. Save both files on desktop.
  2. Power off your Android device, wait while the switch off is completed and afterwards reach recovery mode on your handset: press and also hold the Power, Volume Down and Power buttons – keep doing so until download mode is displayed.
