Steps to Root Samsung Galaxy S9 and Galaxy S9 Plus | how to root galaxy s9
Rooting the Galaxy S9 or S9 Plus is a four-step process.
First, you will need to enable ‘OEM Unlocking’ to allow flashing custom binaries. Once that is done, the second step is to install TWRP recovery on Samsung Galaxy S9/Galaxy S9 Plus. Then the third step is to disable encryption and prevent Prenormal KG/RMM State (Only on Android Pie and Oreo) by flashing the no-verity zip and RMM State Bypass zip files respectively. Finally, when you do it all, the fourth and the last step is to flash the Magisk ZIP using TWRP to root Samsung Galaxy S9 and Galaxy S9 Plus.
While the process might not be as simple as that on devices like Google Pixel, it is still fairly easy. Even if you’re new to the scene, you will easily be able to perform the whole procedure. Just make sure that you follow each and every step as mentioned.
1. Enable Developer Options and OEM Unlock in Settings | how to root galaxy s9
In order to install TWRP and root, you must first enable ‘OEM Unlocking in your Galaxy S9’s Settings menu. To do that, go to Settings -> About Phone -> Software Information and tap 7 times on the ‘Build number’. You shall then see a toast notification – “Developer mode has been enabled”.
Once that is done, go back to the Settings main screen and tap on ‘Developer options’. Scroll down until you find the ‘OEM Unlocking’ toggle and turn it ON. If the option is not yet visible on your device, it means that your phone has entered a 7-day buffer period. After this time (Or, you can try bypassing it using the instructions here), the ‘OEM Unlocking’ option shall be available. If it is still not available, it means that your phone cannot be rooted.
With the option enabled, you can now go ahead and install TWRP on your Galaxy S9/S9 Plus. The next section will take you through the complete process in detail.
2: Install TWRP Recovery on Samsung Galaxy S9 and Galaxy S9 Plus | how to root galaxy s9
- First, download TWRP Recovery for Galaxy S9 and Galaxy S9 Plus.
- Double-click the “Odin3 v3.14.4.exe” executable file to launch the Odin flash tool on your PC.
- Power off the phone completely.
- Hold the Volume Down, Bixby, and Power button simultaneously
- On the warning screen, press the Volume Up button to enter Download Mode on Galaxy S9/S9 Plus.

- Next, click on the ‘AP’ button under the ‘Files’ section of Odin and select the TWRP recovery (.tar) file for your device.
- Finally, click the ‘Start’ button to install TWRP recovery on Samsung Galaxy S9 and Galaxy S9 Plus.
The flashing process would take a few seconds to complete. When you finish it, then your phone shall stay in Download Mode.
3: Flash Encryption Disabler and KG/RMM Bypass ZIPs using TWRP | how to root galaxy s9
Now, for TWRP to successfully decrypt your phone’s storage, you must have to format the data partition and flash the Encryption Disabler zip file.
Note: You only need to flash KG/RMM Bypass zip if your phone is running Android Pie or Oreo. It is not compatible with Android 10.
- Go to the ‘Wipe’ menu in TWRP and tap on ‘Format Data’
- Enter ‘Yes’ in the provided field to completely format the data partition (including internal storage).
- Once finished, go to the ‘Reboot’ menu in TWRP and press the ‘Recovery’ button to reboot your phone into TWRP. This will ensure that TWRP can decrypt the storage.
- When the phone boots back into TWRP, go to the ‘Mount’ menu
- Now select “Enable MTP” and connect the Galaxy S9/S9 Plus to the PC using the USB cable.
- Download DM-Verity disabler and KG/RMM State Bypass zip (Only for Android Pie/Oreo) files from the ‘Downloads’ section above.
- Transfer the files to the phone’s internal storage and then disconnect the phone from the PC.
- Go to the ‘Install’ menu in TWRP and select the Encryption Disabler zip file (e.g. Disable_Dm-Verity_ForceEncrypt_02.24.2020.zip).
- Swipe the button to flash the file and disable encryption on Samsung Galaxy S9/S9+.
- If your phone is running Android Pie/Oreo, repeat the installation method and flash the KG/RMM State Bypass zip to prevent your phone from locked again (Prenormal KG/RMM State).
If you see an error message that says‘Failed to mount /ODM (No such file or directory)‘, you can safely ignore it.
Now, with everything set, follow the instructions in the fourth and final step below to finally root Samsung Galaxy S9/S9 Plus.
