Frequently Asked Questions

What is root?

The name root is the user name or account that by default has access to all commands and files on the Android operating system. Rooting an Android device is simply the process of gaining full, privileged, or admin control of a device, thus allowing ‘root access’ or ‘superuser’ permissions.

For those familiar with Windows, consider an unrooted Android device as being logged in as a guest. As a guest you can use applications and browse files, but you cannot make changes to your system. Rooting your Android device is akin to logging on your computer as the administrator, granting you the permission to alter files and customize your device.

The rooting process itself basically exploits a security weakness on a device, and in simple terms, grants the user executable permissions that are not otherwise there with a non-rooted device. Once a device is rooted, the user has complete control of the device. This means you can overcome limitations that carriers and manufacturers put on your device, extend system functionality, install custom aftermarket distributions of Android (ROMs), and truly make the device your own.

What are the benefits of root?

The advantages of a rooted device are unlimited. Root users are in complete control.

Some notable benefits include:

  • Support for themes, allowing everything to be visually changed from the color of the battery icon, to the boot animation that appears while the device is booting, and more.
  • Full application control, including the ability to backup, restore, or batch edit applications
  • Block advertisements across all apps
  • Install a ROM (i.e. CyanogenMod)
  • Remove bloatware from your device
  • Install a custom recovery (i.e. TWRP or ClockworkMod recovery)
  • Full control of the kernel, which, for example, allows overclocking the CPU and GPU
  • Install Xposed framework and modules to modify system and app behavior
  • Turn your device into a WiFi hotspot (i.e. WiFi tethering)
  • Unlock hidden features, gain performance, and battery enhancements
  • Take advantage of the best backup software Android has to offer
  • Extend the life of your device by installing the latest version of Android

Once rooted you truly own your device. You will have access to modify anything!

Root and security

The rooting process usually includes exploiting one or more security bugs on the device. Once rooted, the su binary is copied to a location in the current process’ PATH (e.g., /system/bin/) and granted executable permissions. A third-party supervisor application, like Superuser or SuperSU, can then regulate and log elevated permission requests from other applications. By using a supervisor application, you can deny superuser permissions to the vast majority of apps and only allow the necessary ones that you trust.

How do I root my device?

We don’t provide a guide to root your device. Rooting methods frequently change. A simple Google search for “root my [DEVICE NAME]” will usually bring up the most popular and up-to-date guide.

Can I un-root my device?

Yes. Apps that control root access (e.g. SuperSU) provide one-click solutions to un-root. Removing root may also involve flashing a RUU, SBF, or something similar. There are many step-by-step guides on how to remove root and return to stock.

Will rooting void my warranty?

It’s legal to root your device; however, in most cases, rooting your device or unlocking the bootloader will void your warranty. If rooted, you should un-root a device before warranty service. Some manufactures have a digital “switch” that flips when you root or unlock the bootloader.

Do rooted devices get over-the-air updates?

If you haven’t installed a custom ROM, you will likely still get over-the-air (OTA) from your carrier. OTA updates may un-root your device.

If you flashed a custom ROM, you will not get OTA updates from your carrier. You may, however, get notifications for updates to your specific ROM.
