Galaxy S5 update to Android 8 Oreo

If you thought that the Samsung Galaxy S5 can no longer be upgraded to Android 8.0 Oreo, think again. It is true that Samsung still has older versions, but this does not mean that you cannot receive updates with third-party solutions. You can really run the latest Android version on your smartphone, but only if you're willing to flash the unofficial ROM version of Lineage OS 15.0. In this guide we will see just how to do itGalaxy S5 update to Android 8 Oreo with the help of LineageOS custom ROM.

Lineage OS 15.0 is an excellent opportunity to install Oreo, especially for users who are stuck on the Android Lollipop, Marshmallow or even Nougat versions. When the official support is interrupted, further updates of the operating system can no longer be officially received. And in these cases third-party support becomes useful. In our case, if you do not choose to install a custom ROM, such as the Lineage system platform, you cannot upgrade the Samsung Galaxy S5.

Galaxy S5 update to Android 8 Oreo

With this method we are going to make an unofficial update since Lineage OS is not developed by Samsung but by third-party developers – in this case we have to thank those of xda-developers for this new upgrade opportunity. Therefore, if it still makes sense, you will lose the Galaxy S5 warranty if you perform this procedure.

For everyday use, the Android 8.0 Oreo ROM of LineageOS 15.0 can work quite well. For the Samsung Galaxy S5 we get a stable environment that can work regularly. Of course, from time to time you may encounter minor problems, but nothing too annoying. With this custom ROM you will have all the latest Android 8.0 Oreo features along with other targeted changes through which you can customize, optimize the Android core center. Overall, after running this guide, your Samsung Galaxy S5 should work faster than before, and you can enjoy improved battery life.

If you've decided to install the Android 8.0 Oreo software, firstrun root permissions on your Galaxy S5. If you don't know how to do it, you can read our guide.

An unofficial update can only be installed on an unlocked system. Furthermore, the custom ROM of the Lineage operating system can only be installed with the help of a custom recovery. So, before anything else, you need to install TWRP recovery on the device.

Before starting, protect your personal data and everything that was not pre-loaded on your Samsung Galaxy S5. If you don't back up before, you will lose all your personal files. This will happen because during the update operation, you will need to perform a complete reset and clear the app data cache: without deleting the Android system you will not be able to successfully install LineageOS.

And since we are talking about precautionary measures, before updating I suggest you also make a Nandroid backup to save system files and protect the current version of the Android operating system. If after testing the Android 8.0 Oreo firmware you decide you want to go back to the standard Android firmware, you will be able to do it easily using the Nandroid backup package. If you don't know how to do it, read this guide.

Now follow these steps before any other procedure:

  • Make sure you can use a computer or notebook to save the required files.
  • On the phone it is necessary to have the rights for the enabled developers; so go up Information phone and tap the build number until you get the message "you are a programmer": You will have to touch it 7 or 10 times in the indicated field.
  • The USB debugging function must also be activated; you can find this option under "menu -> settings -> developer options".
  • need to charge the smartphone before starting the update process, especially if the remaining power is less than 50%.
  • Tip: Your phone can become soft bricked if its system turns off during the flashing process.
  • Of course, the Lineage ROM operating system proposed below is compatible with the Samsung Galaxy S5. So, don't use this guide if you have a different Android device.
