Rootnic allows you to safely and free get the root rights of most devices running the Android OS. No PC, viruses, mandatory installations of third-party "useful" applications.
In order to limit the interaction with system folders and files in any operating UNIX-like systems (in our case, devices running the Android OS) there is a system of access rights. Third-party installable applications that require full administrative rights will not be able to function. Rooted superuser rights (root rights) allow an account to access the root of the system.
