Root Samsung Galaxy S8+ on Android Oreo OS

As you know, once you update your Galaxy S8+ with the latest official firmware your custom access is revoked by default. That’s happening because your smartphone is restored back to factory state, a state ensured by the Android system that’s being flashed. So, shortly, if tweaks were applied, after you resumed the Android Oreo installation process, these tweaks were revoked. Basically, at this moment, and since you are reading these guidelines, you are looking for a new root solution that can be applied on the new Oreo build.

Well, if that’s true, then you have nothing to worry about. The steps explained below will guide you through a dedicated root operation, compatible with your Samsung Galaxy S8+ and with the new Android Oreo firmware.

If you’re trying to root the Android OS for the first time, then there are a few things that must be checked out before. Thus, read all the lines from this tutorial before heading towards the rooting steps from below – that’s the only way in which you can keep everything safe and secured all the time.

The root process will unlock the Android core system that powers your Samsung Galaxy S8 Plus. Therefore, in the end you can enjoy unlimited access towards built-in apps, features, capabilities and towards the overall Android system. So, on a rooted handset you can choose to customize, optimize and personalize the Android functionality in order to improve general performance, bump speeds or upgrade the battery life. Moreover, once this process is completed you can initiate different other tweaks such as: remove bloatware and start-up programs, add custom apps from Google Play or from other sources, apply custom kernels and MODs, update with custom ROMs (such as Lineage OS, AOKP or Paranoid Android), overclock or undervolt CPU frequencies and so much more.

Of course, such unlimited access is coming with a major downside: you will lose your phone’s warranty as Samsung KNOX will be tripped once the root access is ensured. Thus, be careful and try not to mess things up as you can easily end up in soft bricking your Samsung Galaxy S8 Plus. Also, access to some default apps might get lost – the root exploit which will be used cannot be associated with your OEM as it is developed by third party devs. However, the warranty can be restored if you choose to reinstall the stock Android software on your device – that can be done by using Odin.

Additionally, you can root the Samsung Galaxy S8+ that runs on Android Oreo only if the latest version of TWRP recovery is being used. So, before doing anything else, learn how to flash this custom recovery image on your device – if you don’t know how, don’t panic as the steps from below will explain this operation too.

Note: TWRP recovery is a custom recovery image based on CWM recovery and based on a touch based interface. This custom recovery will ensure a virtual path between you and your phone’s internal system and will make possible the root operation.

A backup should be also initiated on your Samsung Galaxy S8 Plus. That must be applied because during the root operation your personal data, info, accounts and files might get corrupted or even wiped out. So, try to protect what’s important for you by completing a dedicated backup process – just choose to use Samsung’s built in cloud storage services, sync your files with your Google Account or download and use specialized backup and restore apps from Google Play. Bottom line, the goal is to save everything that wasn’t there from day one including contacts, call logs, texts, images, videos, audio files, market apps, internet settings, EFS folder, IMEI / NVRAM data and so on.

A computer is also required as these are going to be manual procedures. Of course, your Galaxy S8+ and its USB cable are also needed. Now, on your phone Developer Options must be enabled; if it isn’t you have to go to About Phone (from Menu – > Settings) from where you should tap repeatedly on Built Number (for 7 or 10 taps) until you are receiving the ‘you are a developer’ message. Then, from Developer Options (located within Menu – Settings – Developer Options) check the USB Debugging field.

Charge your Samsung Galaxy S8+ before starting the root operation. You must plug in the charger if the power left is currently lower than 50% – in that case, your phone might remain without power and a sudden shut down might be initiated, situation during which you can end up in soft bricking your device (different problems can cause various malfunctions). Thus, be careful and if implied, wait while your handset is being charged before doing anything else.
