    Mobilinux - Linux for Android

    Mobilinux - Linux for Android

    This application will allow you to install and run Linux on Android !

    The app supports ROOTED as well as NOROOTED devices. Use your mobile as a Pocket PC !! For Root Method: The application creates a disk image on a flash card, mounts it and installs an OS distribution. Applications of the new system are run in a chroot environment and working together with the Android platform. All changes made on the device are reversible, i.e. the application and components can be removed completely. Installation of a distribution is done by downloading files from official mirrors online over the internet. The application requires superuser rights (ROOT).Installing a new operating system takes about 15 minutes. The recommended minimum size of a disk image is 1024 MB (with LXDE), and without a GUI - 512 MB. Noroot Method: Install MOBICONSOLE addon and then install the linux on a non-rooted phone.
