The procedure involves installing a new operating system (OS) onto a device. This action overwrites the existing software with a fresh copy or a modified version. An example includes replacing the stock Android version on a phone with a custom ROM to enhance performance or introduce new features.
The significance lies in its potential to revitalize older devices, granting access to updated features and security patches not officially provided by the manufacturer. It can also unlock advanced customization options, allowing users to tailor their mobile experience. Historically, this process was primarily used by developers and advanced users, but increasingly accessible tools have made it more commonplace.
