Repairing instruction

A number of Gemini x27 unit have received a wrong update which affected the device functionality.

In order to fix the affected Gemini you will need to flash the corrupted Android software in your device with a fixed version. You will need a PC with either Windows or Linux to do this, we suggest to use Windows as it has the best compatibility with the flash tool. Please follow the steps below to fix your Gemini.


1 - Download and Install FlashTool

 The first step is to install the flash tool drivers. These drivers are needed for your Windows or Linux PC to communicate with your Gemini. You can find the drivers here: Windows Flash Tool Drivers


Once downloaded, unzip the archive. You will find a folder called FlashToolDrivers, open the folder and double click on the Install file. Allow the installation to complete by clicking Yes when asked to make changes.

Now that the drivers have been installed, we can download the Windows flash tool:  Windows Flash Tool

If you use Linux you don't need any drivers and you can proceed directly to download the Linux flash tool.

You will need a 64 bit Linux machine and you might need root access to run it. The executable file is flash_tool.sh. If you get a BROM error when connecting the Gemini (see flash_tool console log) then you should follow this guide https://forum.xda-developers.com/general/rooting-roms/tutorial-how-to-setup-spflashtoollinux-t3160802/page16 - specifically the 2 points regarding udev rules.
