The first step to install Linux on your Cosmo is to make sure that you are running the latest Android firmware, currently '''V23'''. You can check the Android version by tapping Settings -> System -> Advanced -> About Phone and scrolling to the end of the page (see Build number detail, in the screenshot below).

Next you will have to download the Linux firmware, which will need to be installed into the microSD card on your Cosmo. Insert a microSD card on your Cosmo and make sure it is formatted as MS-DOS(FAT32).
