Each firmware archive above contains 3 different version of the firmware that can be installed:
- Standard Android firmware
Please use the "Gemini_Android.txt" scatter file to flash the Android firmware. - Rooted Android firmware
With Gemini you have the option to easily root your device. Please bear in mind that rooting an Android device comes with associated risks, and some application might not work correctly. You can search the Internet for more information, we suggest that you proceed only if you know what you are doing.
If you know what you are doing and you want to continue, then you can use the "Gemini_Android_Rooted.txt" scatter file to flash the rooted Android firmware. Please complete the process by installing Magisk Manager. - Dual Boot Android/Linux
To install a dual boot Android/Linux image you must first partition your Gemini, deciding how much space to reserve for each system and what system you would like to boot into by default. For example, if you specify to boot into Android by default, then the Gemini will boot into Android when started. To boot into Linux, you will have to press the side button when booting. You can configure the space and the default booting system using this partition tool: http://support.planetcom.co.uk/download/Old/partitionTool.html
Make sure you reserve enough space for Linux, you will need around 5 GB of space for Debian. The flash tool will show you an error message if the partition size is too small.
When you have selected your parameters, click on the "Download Scatter file" button to retrieve a copy of the Gemini_Dual_Boot.txt scatter file and place it in the folder containing the firmware. You can now use this scatter file to flash a dual boot Android/Linux firmware on your Gemini. Don't forget to check out this Web page for further information about
