Since TWRP recovery was made available for the Exynos model of the Samsung Galaxy S9 Plus, now you can successfully choose to gain root access on your smartphone. So, if you’re ready to experience new tweaking opportunities for your device and if you’re ready to customize the Android functionality, you should start checking out the guidelines explained below. There we will talk about the root advantages and risks, about the pre-requisites that should be first ensured and about the actual root steps that must be followed and applied on your S9 Plus so that, in the end, you can enjoy a fully rooted and functional Android UI.
For being able to unleash the true power of your Samsung Galaxy S9 Plus you have to get rid of factory restrictions. These restrictions are there to limit your access in terms of further modifications within the Android core system. Shortly, if you want to customize, optimize and personalize the Android functionality you cannot do it unless you first remove default restrictions and that can be achieved when root is enabled. And that’s the main reason why you should follow this step by step guide.
And for clearing things up, here are the main tweaks that can be applied on your Samsung Galaxy S9 Plus once root privileges are gained: you can remove bloatware from your Samsung branded device, you can delete certain start-up programs that are slowing down your device, you can add new features and apps that cannot be found on the stock Android firmware, you can download apps from other sources than Google Play, you can install custom ROMs for testing new and unofficial Android updates, you can set up custom MODs and kernels and you can even overclock or undervolt your handset for increasing speeds or upgrading battery life.
But, removing factory restrictions will make you lose your Galaxy S9 Plus warranty – that happens because Samsung KNOX will get tripped during the root process: the root exploit is not offered by Samsung and cannot be associated with your OEM in any matter. Basically, you are going to perform an unofficial operation and in the end you can even lose access to certain built-in apps. Anyway, if required, the warranty flag can be restored; however, in that case you have to reinstall the stock Android software via Odin, when everything will be restored back to factory state, so root will be also lost.
A custom recovery image must be used during the root operation. That’s needed because the root exploit must be flashed from a custom recovery environment. Thus, before choosing to do anything else you must first learn how to install TWRP recovery on your Samsung Galaxy S9 Plus.
Just before starting the root operation make sure that your personal data, info, accounts and files are secured. The best will be to make a backup in order to save as much as possible – contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and so on. Taking care of the backup is more than recommended because during the steps from below a full wipe will have to be completed – you will make a hard reset and clear app data cache as otherwise the root access can’t be granted.
You can save your files by using different solutions: on Google Play you can find different backup and restore apps, you can use an external storage device, Samsung already installed dedicated clod storage platforms, or you can just sync some files with your Google Account. And, additionally, you can use the recently installed TWRP recovery platform and initiate a Nandroid backup – in that way you can save the current Android OS that runs on your Galaxy S9 Plus and you can also restore it if problems will occur during the root operation.
Charging your phone before doing anything else it will also be a good idea especially if the power that’s left on your device is lower than 50%. Different software related problems and malfunctions (an Android soft-brick can be also issued) can be caused if a sudden shut down happens in the middle of the root operation. So, avoid any unpleasant situations and plug in the charger first if that’s needed.
The root files must be downloaded on a computer first. Thus, make sure you can use a PC in that regard. Of course, your smartphone and its USB cable will be required too because a connection between your phone and your computer will be needed at some point.
On your S9 Plus access Developer Options from Settings. If you cannot do that, go to About Phone and tap repeatedly on Built Number for 7 or 10 times until the ‘you are a developer’ message is returned. Finally, from Developer Options check the USB Debugging feature.
