Your HTC One M9 is now rooted and you can confirm it using the Root Checker app.

Now that you have rooted the HTC One M9 smartphone by installing a custom recovery image over the stock recovery partition and then flashed Chainfire’s SuperSU, you can install every root applications out there in existence.

Many people spend lots of time pondering what way they are going to choose to root a device, but if you are spending time thinking about the outcome in terms of the apps available, then you are wasting your time. It never matters what way you choose to get root access to the internal Android system for installing the apps. Once you are the root user, then that is all that matters and every app that requires root access will now run. That would remain true even if you are using a smartphone from the United States and using something like KingRoot which his a Chinese rooting tool. It still doesn’t make any difference.

The main difference between rooting Android with a custom recovery and flashing SuperSU in comparison to using a one-click rooting tool is that people who want to install custom ROMs and custom kernels need to have the custom recovery installed so they might as well root the device this way. Everyone else who is just rooting the Android operating system for the sake of being able to install root apps doesn’t need to bother installing a custom recovery image and can just use a one-click rooting tool instead.

Of course, there are times when you don’t have multiple methods available. That is particularly right if you are using a new device that hasn’t been out for a long time and you are checking out what methods are out there and available for your to get root access. When that’s the case then many people resort to doing whatever is available.
