If you thought that the Samsung Galaxy S5 cannot run on Android 8.0 Oreo, think again. Yes, the Samsung support is still stopped, but that doesn’t mean you cannot receive some third party treatment. Well, in that respect, you can indeed run the latest Android build on your smartphone, but only if you’re willing to go wild – and when I say wild I mean testing and trying the unofficial release of Lineage OS 15.0. So, shortly, during the following lines we will be checking on how to update the Samsung Galaxy S5 to Android 8.0 Oreo with the help of the LineageOS custom ROM firmware.
Lineage OS 15.0 is a great Oreo opportunity especially for the users who are stuck on Android Lollipop, Marshmallow or even Nougat. Why? Well, when the official support gets stopped you cannot officially receive further OS improvements. And that’s when the third party support comes in handy. In our case, if you don’t choose to flash a custom ROM software, like the Lineage OS platform, you cannot update your Samsung Galaxy S5 – it’s just that simple.
So, first thing first: you are about to complete an unofficial update operation since Lineage OS is not developed or offered by Samsung but by third-party devs – in this case we must thank those of xda-developers for this new update opportunity. Therefore, if that still makes any sense, you are going to lose your Galaxy S5 warranty if you choose to apply the steps explained during this tutorial.
In term of everyday use, the Android 8.0 Oreo powered LineageOS 15.0 ROM manages to do everything right. For the Samsung Galaxy S5 we get a stable environment that can smoothly run on a daily basis. Of course, from time to time you might still find minor issues or soft related problems, but nothing too annoying. And, don’t forget, with this custom ROM you get all the latest Android 8.0 Oreo features, apps and capabilities along with other dedicated tweaks through which you can customize, optimize and personalize the Android core center. Overall, after completing this step by step guide your Samsung Galaxy S5 should run faster than before, better than it used to and everything while you will be enjoying an upgraded battery life.
Now, if you decide to try the Android 8.0 Oreo software first root your Galaxy S5. An unofficial update can be flashed only on an unlocked system and with root you can achieve that. Moreover, the Lineage OS custom ROM can be flashed only if a custom recovery image can be used. Thus, flash TWRP recovery on your smartphone before doing anything else.
Secure your personal data and everything else that was not pre-loaded on your Samsung Galaxy S5. If a backup isn’t completed first you will lose all your personal files. That will happen because during the update operation you will have to make a hard reset and clear app data cache – without wiping the Android system you cannot successfully install LineageOS. So, be careful and also prepared for what will follow – just save your personal files by using your favorite backup and restore solutions.
And since we are talking about precaution measures, a Nandroid backup is also recommended. That’s how you can save system files and secure the actual Android OS. Thus, if after you test the Android 8.0 Oreo firmware you decide that you want to go back to the stock Android firmware, you will be able to easily do so by using the Nandroid backup package.
After taking care of the essential pre-requisites from above you still have to review the next tasks. These are general operations that should be completed before each manual procedure that will be applied on the Android system. So:
- Make sure that you can use a computer, a notebook or any other similar device – there you will save the required files.
- On your phone you need to have Developer rights enabled; so, go to About Phone and tap on Built Number until you get the ‘you are a developer’ message – you will have to tap for 7 or 10 times on the mentioned field.
- The USB Debugging feature must be checked too; you can find this option under “menu – > settings – > developer options”.
- You need to charge your smartphone before starting the update process – especially if the power left is lower than 50%.
- Hint: your phone can get soft bricked if its system will get switched off during the flashing process from down below.
- Of course, the Lineage OS ROM offered below is compatible with the Samsung Galaxy S5. So, don’t use this step by step guide if you have a similar or a different Android based device as you will only manage to mess things up.
