Rooting an Android phone gives you more access to the operating system, increasing the level of customization. Since Android phones are so different, there is no single root method that works on all or all versions of the operating system. To get started, you need to download the appropriate program for your model (almost all of them are only available on Windows), enable USB debugging from your phone, and set up USB drivers on your computer. Don't forget to backup your data before starting the operation.

Advice
- Even if your phone is connected to the computer during the operation, it is still a good idea to charge it before starting. If it were to download in the course of root, the software could be damaged.
- Download and run an application that allows you to check if the phone is rooted to be sure that the operation was successful.
Warnings
- Make sure the software you are using is suitable for the model and version of the phone you are trying to modify. An error can cause the operation to fail and potentially break the device.
- Unlocking the bootloader and rooting your phone can void your warranty.
- You may not be able to root some phones. This is especially true for the newer models, so make sure you get the desired result before you try. Otherwise, the consequences can be many and varied, from a simple waste of time to breaking the phone.
