Many thanks for the Cosmo Communicator open source community
that provided an initial version of Linux for Cosmo Communicator!
The first step to install Linux on your Cosmo is to make sure 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 as in the following screenshot.
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).
You can download the latest archive at this

Alternatively, you can also purchase a Linux Media Installation Card with the firmware already preloaded onto the micro SD card. This can be purchased from [https://store.planetcom.co.uk/collections/media-books https://store.planetcom.co.uk/collections/media-books/]
The main requirement when installing Linux is to reserve space for it. In order to do this you will have to re-partition your device, which will lead to the loss of all your data. Once you reserve some space for Linux you can update Android or Linux independently, without loosing your data again. To change the partition table of your Cosmo use the option "Change the partition table of your COSMO", as in the picture below.
# EMPTY_RECOVERY_BOOT_2 - This partition can be used to store an image that runs in recovery mode, such as TWRP
Follow the installation steps above and just remember that TWRP can only installed in the EMPTY_RECOVERY_BOOT_2 partition.
Next, go to the Layouts tab where you can select your own Cosmo keyboard layout. For
examole, to select the British UK keyboard layout, tap on "Configure layouts" and specify the English (GB) keyboard layout, as in the following screenshot.
You can also use command line to set the keyboard hardware model and layout. The following command can be used to set the
kebyoard layout to English (GB):
<code>setxkbmap -model planetgemini -layout gb</code>
NetworkManager also supports mobile data, but it does not work well with Cosmo.
If you want to enable mobile data [[Mobile Data In Linux Cosmo|please follow this guide]].
