Many people are switching over and using the Android OS because it’s easy to unchain internal system. It’s not always as easy as it sounds, though because Google can patch known exploits and vulnerabilities at any time, leaving people with what they thought was a useful guide, with a guide that bricks their device.

If you have the HTC One M9 smartphone and have accepted the official OTA notification for Android 5.0 Lollipop, you should be searching for a new guide as we have here today and not follow the older guide.

What Is Rooting the Android Operating System?

When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.

Why Would You Want to Root Android?

Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:

  • Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
  • Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
  • Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
  • Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.

What Are the Risks of Rooting?

If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.

With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:

  • Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
  • You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
  • You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.


  • The HTC One M9 smartphone.
  • Unlock the bootloader.


  • You should install the HTC Sync software on the computer; it comes with the drivers.
  • You must install a custom recovery image first before starting the rooting guide. You can pick between TWRP recovery and ClockworkMod recovery.
  • Backup the data before starting using one of the many apps from Google Play.


  1. Download SuperSU 2.49 to the computer desktop.
  2. Connect the M9 to the same computer and transfer the SuperSU file to the root of the internal storage SD card.
  3. Unplug the M9 from the computer and completely power down the handset.
  4. Boot it up into the custom recovery of your choice you must have pre-installed. It can be either TWRP or CWM, as I previously mentioned.
  5. Choose the “Install” option or the “flash zip from SD card,” depending on your recovery.
  6. Browse the SD card storage for the SuperSU file you transferred earlier. You can navigate by using the Volume Up and the Volume Down buttons.
  7. Wait for the SuperSu to finish installing before heading back to the main recovery menu.

Now select to reboot the system, and you’re ready to flash a custom ROM.
