All of the special ROM rows are now possible due to Google's genuine drive to combat software fragmentation with Project Treble. Now AOSP's ROM can be easily flash to all Project Treble-supported devices like Galaxy S9 and S9 +, Project Treble ROMs just create their own name in the Android community.
However, with a large power of custom ROM and root access, there is a locked issue of the most common services. With a rooted Trekle ROM device, you may not be able to use Android Pay and the device will not be able to pass SafetyNet checks as well. So if you want to keep the latest version of Android with Project Treble ROM but remove root access here that you can do.
- Save the downloaded file on your device's internal storage and power off.
- Reboot device and access TWRP custom recovery menu.
- Press the Install button and navigate to UnSU Script Download
- Slide to install and wait when the process is complete, after which you can reboot.
After the device restarts, root access on your device will no longer be available, regardless of whether you have SuperSU or Magisk installed
