{{Main|Rooting (Android)}}
Android phones can be officially rooted by either going through manufacturers controlled process, using an exploit to gain root, or installing a rooting modification. Manufacturers allow rooting through a process they control, while some allow the phone to be rooted simply by pressing specific key combinations at boot time, or by other self-administered methods. Using a manufacturers method almost always factory resets the device, making rooting useless to people who want to view the data, and also voids the warranty permanently, even if the device is derooted and reflashed. Software exploits commonly either target a root-level process that is accessible to the user, by using an exploit specific to the phone's kernel, or using a known Android exploit that has been patched in newer versions; by not upgrading the phone, or intentionally downgrading the version.
