'''28/04/2021 - The latest Linux Debian firmware v4 is now available!'''
  
 +
<span style="color: #ff0000;">Please note we are investigating an issue related to not receiving incoming calls with this version of Linux.</span>
  
 +
Thanks to the ongoing support from the open source community, today we are glad to release the latest Linux Debian v4 for Cosmo Communicator!
  
 +
This latest release provides bug fixes and new features:
  
 +
* Support for Camera is now available
 +
* Improved boot screen and lock  screen
 +
* Support for dual keyboard language layout. If you use a dual keybaord layout, such as Japanese, you can press both shift keys at the same time to cycle between the layouts (i.e. english and japanese).
 +
* New installation program allows you to select your keyboard layout and time zone. The information is then stored in phone settings and retained even after Linux reinstallation.
  
==Linux installation==
+
Please note that altough it's possible to keep using Linux v3, updating from v3 to v4 using apt is not possible.
The first step to install Linux on your Cosmo is to make sure you are running the latest Android firmware, currently v19. 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.
 
  
[[File:36.jpg|center|640x320px|border]]
+
'''It's therefore recommended to use the guide below to install Linux v4.'''
  
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).
+
Notes on Linux v4 installation:
  
 +
* The new installer will allow you to select your keyboard layout and time zone
 +
* If you use a dual keyboard layoyut, your settings might not be picked up on the very first boot. For example if you choose Japanese layout, on your first boot the screen and keyboard layout could still be set to English. Simply reboot the unit and both the language and keyboard layout will be fully configured. Remember you can switch between the 2 keyboard layouts by pressing both left and right shift buttons at the same time.
  
You can download the latest archive at this address:

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.

Linux News

28/04/2021 - The latest Linux Debian firmware v4 is now available!

Please note we are investigating an issue related to not receiving incoming calls with this version of Linux.

Thanks to the ongoing support from the open source community, today we are glad to release the latest Linux Debian v4 for Cosmo Communicator!

This latest release provides bug fixes and new features:

  • Support for Camera is now available
  • Improved boot screen and lock  screen
  • Support for dual keyboard language layout. If you use a dual keybaord layout, such as Japanese, you can press both shift keys at the same time to cycle between the layouts (i.e. english and japanese).
  • New installation program allows you to select your keyboard layout and time zone. The information is then stored in phone settings and retained even after Linux reinstallation.

Please note that altough it's possible to keep using Linux v3, updating from v3 to v4 using apt is not possible.

It's therefore recommended to use the guide below to install Linux v4.

Notes on Linux v4 installation:

  • The new installer will allow you to select your keyboard layout and time zone
  • If you use a dual keyboard layoyut, your settings might not be picked up on the very first boot. For example if you choose Japanese layout, on your first boot the screen and keyboard layout could still be set to English. Simply reboot the unit and both the language and keyboard layout will be fully configured. Remember you can switch between the 2 keyboard layouts by pressing both left and right shift buttons at the same time.

For more information about this release, please see here.


11/12/2020 - Linux update

Older Linux Debian v2 firmware

The Linux Debian v2 firmware has numerous bug fixes and supports the following new features:

  • Phone Calls
  • SMS support
  • 4G Mobile data support using connman
  • Open/Close power save support

Cosmo Linux installation

Before installing Linux, make sure you have the latest Android Firmware installed, currently v25.

Touchpad functionality for Linux is added in the latest CoDi, version 1.1.1.16.

Download and Install Linux firmware v4 (latest)

You will have to download the Linux firmware file, which will need to be installed onto 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 file at this URL:

Older versions:

Alternatively, you can also purchase a Linux Media Installation Card with the firmware already preloaded onto a micro SD card. This can be purchased from https://store.planetcom.co.uk/collections/media-books/

Once you downloaded the zip archive you will have to extract its content onto your microSD card:

  1. Using the Files app (do not use File Manager app) locate the ZIP archive
  2. Tap the archive file to reveal the cosmo-customos-installer folder
  3. Long tap on that folder, select Extract to... and finally select the root folder of the microSD card as destination.
  4. Complete the ZIP extraction process.
  5. Your microSD card should now contain a folder named cosmo-customos-installer with several files inside it.


Next, you will have to boot into recovery mode. To do that, simply turn ON your Cosmo while keeping pressed the volume up button on the outside cover. The volume up button is the one on the fingerprint sensor, which points UP when the unit is open. The unit should boot into recovery mode and you should be able to see the Android logo, but nothing else - as in the following screenshot.


39.jpg


At this point, keep the ESC key pressed (top left key on the keyboard) and press the volume up button from the outside cover again, then release both keys. This following menu will be displayed.

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.

Screenshot 2020-02-12 at 15.12.52.png


You will have 5 options to choose from:

  1. Reserve all space for Android
  2. Reserve 90GB for Android and 30GB for Linux
  3. Reserve 60GB for Android and 60GB for Linux
  4. Reserve 30GB for Android and 90 GB for Linux
  5. Reserve all space for Linux


Screenshot 2020-02-12 at 15.15.52.png

Note that in recent firmwares you will also have the option to keep all the storage for Android while allowing the installation of TWRP and rooted Android, which is useful if you want to have a rooted Android without using Linux.

If you select to install Linux, 4 additional partitions will be created:

  1. EMPTY_RECOVERY_BOOT_2 - This partition can be used to store an image that runs in recovery mode, such as TWRP
  2. EMPTY_NORMAL_BOOT_3 - This partition can be used to store Debian/KDE or Rooted Android
  3. EMPTY_NORMAL_BOOT_4 - This partition can be used to store Debian/KDE or Rooted Android
  4. In addition, an extra partition will be created with the custom size selected by the user, which will be used to store the root file system.

Once the storage for Linux has been reserved, you can install a custom OS on your Cosmo, by choosing the related option as in the picture below.


Screenshot 2020-02-12 at 15.18.42.png


This option will scan the microSD card for compatible installers and will present you with a menu showing the available installers as in the picture below.

43.jpg


Whenever new or updated custom operating systems will be available for the Cosmo, you will be able to download them into a micro SD card and install it in your device.

Once you select a custom OS you have to select where to install its boot firmware. Remember that you can install TWRP only on the EMPTY_RECOVERY_BOOT_2 partition, while you can install Debian/KDE and the Rooted android image in either EMPTY_NORMAL_BOOT_3 or EMPTY_NORMAL_BOOT_4 partitions.

Once you select the boot partition, the custom OS will be installed on your Cosmo Communicator. A boot menu will then appear when you turn ON the device, allowing you to choose what to start as in the following picture.


46.jpg


Using this method you will be able to install a custom OS such as Linux on your device without the need for a laptop or a desktop computer. All you need to do is to download the installer in a micro SD card and use the recovery mode to start the installation.

You can watch a Cosmo Communicator How-To video detailing the Linux installation process from SD card at this address https://youtu.be/7guqI4nA8CU

TWRP installation

Please use caution when using TWRP as it can brick your device.

TWRP support is limited for Cosmo Communicator (you can't access the encrypted user data partition) and its usage is discouraged.

Use it at your own risk.

Follow the installation steps above and just remember that TWRP can only installed in the EMPTY_RECOVERY_BOOT_2 partition.

Debian/KDE installation

Simply follow the installation steps above. The Debian/KDE installer will automatically install the boot image into the selected partition and it will also install the rootfs image into the Linux partition.

The latest Linux v4 will automatically configure the keyboard layout based on the installation choice. The following guide is obsolete and kept as reference.

Keyboard Layout Configuration

The default keyboard layout is American English, to configure a different layout, see the example command below.

The following command can be used to set the keyboard layout to English (GB):

setxkbmap -model planetcosmo -layout gb

To restore the layout to English (US), use the following command:

setxkbmap -model planetcosmo -layout us

WIFI Configuration

To setup the WIFI connection tap on the NetworkManager icon on the bottom right, select the WIFI network you want to connect to and tap Connect.

10.jpg

After entering the password, the system will ask you how to store the password. If you want to store it without entering a password, then select the first option "Classic, blowfish encrypted file" and when asked to enter a password just leave it empty and tap OK. The system will then popup a warning that the password has a low strength, just tap on the Yes button.

21.jpg

Phone and Message apps

The latest Linux update comes with a phone dialler and an SMS message app. They are available under the Phone application category

23 33.jpg

Both applications are quite simple and work as expected. Both apps have a special button at the botton that can be swiped up to reveal more information. For example the Phone Dialler app will show recent and missed calls as in the picture below.

Enbling Mobile Data

Please note that WIFI, Phone calls and SMS work straight away.

The default NetworkManager application also supports mobile data, but it does not work well with Cosmo.

To activate mobile data please follow this link.

Tips

  • There is a default user named 'cosmo'. The password for the 'cosmo' user is 'cosmo'
  • To update your Linux installation, make sure you configure a WIFI connection and then:
    1. Become root by typing 'sudo bash' followed by the 'cosmo' password
    2. type 'apt update'
    3. type 'apt upgrade'.
  • On Linux, the ESC key sends the Escape command on Linux. To send the power command, use Fn+ESC.

Rooted Android installation

Please see this page for instruction on how to install Rooted Android on a Cosmo.


The following information is now outdated and kept as reference only.

Install the Rooted Android image as per the installation above.
After booting the rooted Android partition, complete the installation by downloading and running Magisk Manager (https://magiskmanager.com). The Magisk Manager interface should then be similar to the following screenshot (notice the green OK icon, device IS rooted).


53.jpg


If instead you run Magisk Manager from a normal Android boot (not rooted), it will look like in the following screenshot. The red icon shows that the device is NOT rooted.
