Gemini 4G x27 firmware restoration

If your Gemini firmware is being damaged or corrupted your Gemini might be stuck in a boot loop animation screen. To restore your unit you will need to update your Android software in your device by using the Flash Tool. 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 update your Gemini and restore firmware to full functionality.

Step 1 - Install FlashTool software and drivers

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

Once downloaded, unzip the archive and extract the files.
You will find a folder called FlashToolDrivers, open the folder.
Run the install file by double clicking on the Install file (Install.bat).

Allow the installation to complete by clicking Yes when asked to make changes.

Now that the drivers have been installed, please download the Windows flash tool from this link  Windows Flash Tool. Please unzip the archive and extract the FlashToolWindows folder.

If you use Linux you don't need any drivers and you can proceed directly to download the Linux flash tool on this link Linux flash tool. You will need a 64 bit Linux machine and you might need root access to run it. Unzip the archive and extract the FlashToolLinux folder.

You have now completed step 1.

Step 2 – Download Gemini Firmware

Download the Gemini 4G x27 firmware from this linkGemini 4G x27 firmware

Unzip the downloaded archive and extract the Gemini_Android_x27_v1_16032018 folder.

Step 3 – Flashing the Android Firmware

Once downloaded please unzip both the flash tool and the firmware. Next, on Windows just run the flash tool by double clicking on flash_tool in the FlashToolWindows folder .On Linux, the executable file is If you get a BROM error when connecting the Gemini (see flash_tool console log) then you should follow this guide - specifically the 2 points regarding udev rules.
On both Windows and Linux, use the choose button as in the following screenshot to load the scatter file that you will find inside the downloaded firmware. In particular:
  • Downlad-Agent should be set to the file MTK_AllInOne_DA.bin, which is located in the FlashToolWindows folder.
  • Scatter-loading file should be set to the specific scatter file (Gemini_Android.txt) of the firmware that you want to flash, which is located in the firmware folder.

Once you select the scatter file, make sure you only select the system partition. By flashing only the system partition and not the rest, you will be able to fix your Gemini while keeping all your data, which are stored in the userdata partition. If you choose only your system partition, your screen should look like the following screenshot.
