TWRP Custom Recovery has been developed for the Galaxy S9 and the Galaxy S9 Plus as well. The lucky Galaxy S9 or the S9 Plus owners who want to unleash the real power of the phone can now flash the TWRP recovery. The TWRP Recovery can be used to perform various tasks that the phone manufacturer doesn’t want the users to access. If you do not have any past experience of using a TWRP Recovery, then let’s learn a little bit about it first.
Custom recoveries like the TWRP and CWM work in the bootloader of the smartphone. These recoveries replace the stock recovery of a phone. The stock recoveries have limited options that can be used to flash official update files or to factory reset the phone. If you want to take Nandroid Backups or you want to access the advanced Wipe options, you need TWRP recovery for that.
The phone manufacturers never recommend installing a custom recovery as the recoveries are developed by third-party developers. Custom recoveries also void the warranty of a phone which is another reason for the manufacturers to discourage its installation. However, all these reasons are not enough to keep an Android enthusiast from modifying his/her phone.
Now that we are talking about a phone like Galaxy S9 and S9 Plus, we will learn about the possibilities of modifications on these phones only. Galaxy S9 and S9 Plus are pure powerhouses in their stock form, but that doesn’t mean you can’t go the extra mile to raise their limits. With the help of a TWRP custom recovery on the S9 or S9 Plus, you can install Xposed Framework.
The Xposed Framework has got thousands of modules that can add tons of features to your phone. For instance, you can run YouTube in the background, you can block all those flashy advertisements, you can tweak the battery life and performance of the phone.
Right after installing the TWRP custom recovery on Galaxy S9/S9 Plus, the very first thing you would want to do is going to be backing up the EFS partition. After EFS partition, you can consider backing up Nandroid and all other partitions. Then there is the wipe option which allows wiping Dalvik Cache along with other partitions individually.
TWRP also comes with its own terminal which can be used to sideload apps and ROMs. The install option in the recovery will let the S9 owners install .zip and .img files. Even if you want to root your S9, you are going to need TWRP because this is the only way to flash SuperSU or Magisk on your phone.
I hope all that explanation was good enough to give you a clear idea of TWRP custom recovery and also how it can help your brand new Galaxy S9. Assuming that everything’s clear, we will now have a look at the tutorial to install TWRP Custom Recovery on Galaxy S9 or S9 Plus.
