====New Linux Installations====
Before starting the installation, please be sure that you are running the latest Android firmware, currently '''
V23 (Requirement 1)'''.
====Requirement 1 - Latest Android firmware
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).
====Requirement 2 - Codi firmware v15====
To take full advantage of the latest features (such as CoDi trackpad control) you will need to manually install CoDi v15. Flashing this firmware is a relatively quick process, because it does not contain the (big) resource file. However, you should make sure you have the latest v14 CoDi firmware and resources before starting this update. Once your CoDi is running v14, you can proceed to manually flash version v15. You will need to download the firmware from this location: [http://support.planetcom.co.uk/download/Cosmo_firmware-stem_ospi2_mouse15.bin http://support.planetcom.co.uk/download/Cosmo_firmware-stem_ospi2_mouse15.bin] (save it to the internal memory into the root directory) and install it manually using the Cover Display Assistant app on Android. The flashing process does not need the second resource file but it assumes that the v14 firmware is installed. [[File:IMAGE2020-11-18. jpg|center|800x400px]]
Select "Advanced" and then "Flash Image Manually" and then select the<span style="color: #000000;"> Cosmo_firmware-stem_ospi2_mouse15.bin. To update the CoDi firmware click on the "FLASH NOW" button. '''After flashing, please ignore any over-the-air Cover Display assistant notifications to update firmware as this is a custom build. '''</span>
