→Multi boot Android-Linux firmware (Sailfish OS + Debian options)
When the Gemini is OFF, press Esc(On) key for around one second to initiate the booting process. Immeditately after that, the unit will vibrate, and after a few seconds the screen will turn ON. When the screen turns ON, the Gemini will check the status of the Esc (On) key and of the side silver button. Based on the status of those buttons there are 4 possible booting modes:
* Boot 1:
Both Esc (On) key and side button are not pressed. This is the default booting option when no buttons are pressed.* Recovery Mode: Esc (On) is pressed. This will always boot into overy mode.* Boot 2: Side button is pressed.* Boot 3: Esc(On) key is pressed and Side button is also pressed < br / >< br />
Using the tool available at [http://support.planetcom.co.uk/partitionTool.html http://support.planetcom.co.uk/partitionTool.html] you can customise what operating system to run when a specific boot mode is selected.
