Being able to experience a great Android UI on a daily basis is possible only if you learn what kind of tweaks to apply, depending on what you wish to achieve from your Samsung Galaxy S9 Plus. But regardless of the custom operations that you will eventually perform for customizing and optimizing the built-in Android system, you will have to set up a custom recovery image first. And in that regard we are here with a detailed tutorial which will show you the easiest way in which TWRP recovery can be now installed on the Samsung Galaxy S9 Plus.
By default your Samsung S9 Plus is running on stock recovery, an environment from where you can access the Android UI and perform certain customization and optimization procedures – for example, you can initiate a hard reset, you can manually add a new OTA package or you can clear app data cache. Now, the TWRP recovery platform will replace the stock recovery and will extend the access that you have within the Android core system. That’s why, on the new custom recovery environment you will be able to initiate endless tweaking procedures for being able to unleash the true potential of your Android powered handset.
And, in that respect here are a few proofs in terms of tweaks that can be easily applied from TWRP recovery: you can quickly gain root access on your Galaxy S9 Plus, you can remove bloatware, you can add root-only apps and tools from other sources than Google Play, you can make Nandroid backups for saving Android files, you can set up custom MODs and kernels, you can update your phone with custom ROMs such as Lineage OS, AOKP or Paranoid Android, and you can even overclock / undervolt CPU frequencies.
TWRP recovery is a platform that extends the use of stock recovery image. Is based on CWM recovery and features a touch-based UI along with extremely useful settings through which tweaks can be performed on your Galaxy S9 Plus. However, it is a third party app that cannot be associated with your OEM. So, completing this guide is implying in performing an unofficial operation. Thus, to conclude these lines, you will most likely lose your phone’s warranty and the access to some built-in apps – Samsung KNOX will get tripped, though it can be reverted if you choose to reinstall the stock Android firmware on your handset, situation during which everything will be restored back to default state.
You need to make a backup on your Samsung Galaxy S9 Plus before flashing the TWRP recovery software. It’s important to take care of what might be still required afterwards as during the steps from below you will have to make a hard reset and clear app data cache. Shortly, you can lose sensible data including stuffs like contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, EFS folder, IMEI / NVRAM data and similar other packages. A complex backup can be applied quickly, in several ways: through built-in Samsung cloud storage tools, by using already tested backup and restore apps from Google Play, by syncing files with your personal Google Account or by using an external storage device.
It’s going to be a manual flashing process and a computer will be required. And, for setting up TWRP recovery Odin will be installed on your PC – this flashing program is developed and also offered by Samsung, so from this perspective you have nothing to worry about as you won’t have to use a risky or complex third party program.
On your phone you must access Developer Options. As you might know, this field should be located under general Settings and if you don’t find it there just follow: navigate towards About Phone and in there start tapping repeatedly on Built Number and keep doing that until the ‘you are a developer’ message pops up.
Your Galaxy S9 Plus and its USB cable will be required below – a connection between your phone and your PC will have to be established. And for making things work on your PC you first have to install the Samsung Galaxy S9 Plus drivers and you can do that by using the Samsung KIES toolkit.
Charge your Android device before starting this manual tweaking process. It is important to plug in the charger especially if the power that’s left is lower than 50%: in that case while trying to install TWRP recovery your S9 Plus might get switched off and a sudden shut down might cause severe problems on your device (you can even end up in soft bricking your smartphone).
Experiencing software related problems might happen if you choose to follow this step by step guide if you don’t own the Samsung Galaxy S9 Plus – use the steps from below only if you have the Exynos model of this device. Don’t do it otherwise as you will only end up in messing things up.
