How to: Mount System RW in Android

Google's Android smartphone operating system uses Linux, UNIX and Java as base. This means that advanced users can utilize a terminal interface, giving commands and instructions to Android via a command line instead of a graphical interface. Root-enabled users can set the System folder to a read/write state, just like a command line on a Linux system. Using a command line is an advanced technique - novice users should avoid terminal interfaces.
