<div style="text-align: justify;">'''Important Note: <span style="color: #ff0000;">please don’t use other tools to flash firmware fo your Gemini as it’s easy to loose key information such as the IMEI number. In particular, never use the “Format all + download“ option in the SP Flash Tool as this erases key information stored in the NVRAM partition and can lead to a non-functional device.</span>'''</div>
 
==Download and Install FlashTool on Windows==
The first step to install FlashTool on Windows PC is to install the flash tool drivers. These drivers are needed for your Windows PC to communicate with your Gemini, the minimum requirement is to have a 64bit Windows operating system.
==Download and Install FlashTool on Linux==
'''The following procedure has been tested on Debian 9.0, Ubuntu 18.04 (see notes below) and Fedore Fedora 28 (see notes below).'''
You can find the latest Linux flash tool software here: [http://support.planetcom.co.uk/download/FlashToolLinux.tgz Linux Flash Tool]
== Flashing Flashing the Gemini with an alternative firmware==
Be sure to follow the previous step to store a copy of the NVRAM partition as backup. Now, run the Flash tool software and click on the '''Download''' tab. Next, locate the '''Scatter-loading File''' option and click on the associated '''choose''' '''button''', as highlighted in the picture below:

Now, open the firmware folder from the firmware zip file you downloaded and select the scatter file. If you selected an Android firmware, then the scatter file will be called''' Gemini_Android.txt'''. If you selected an Android/Linux firmware, then the scatter file name will depend on the space you reserved for them, for example''' Gemini_x27_A26GB_L30GB_Multi_Boot.txt'''.
Make sure all the partitions are found and are checked. If some partitions are not found (location tab is empty), double checked that you unzipped the Linux module in the firmware folder.
Finally, change the '''Download Only''' drop down menu to '''Firmware Upgrade''' and click on the '''Download''' button. When switching between a standard Android to a dual boot Android/Linux firmware, you must use the '''Firmware Upgrade '''mode because you need to format the device and change the partitions.
Connect your Gemini and restart it. As soon as the Gemini is rebooted, the flash tool will detect the device and it will update the OS with the selected firmware.
 
To update the Android firmware, simply download the latest Android firmware from [http://support.planetcom.co.uk/index.php/Gemini_Firmware http://support.planetcom.co.uk/index.php/Gemini_Firmware] and use the '''Download Only''' option while selecting only the system partition, as in the screenshot below
