Flashing the Image

Download the image

Download the image file from the link in downloads, you can get the newest version which is not in beta.


Extract to an .img file.

Update the firmware

Using Windows:

  1. Download and install DriverAssitant tool from the downloads(3]) page
  2. Download and extract "Firmware Upgrade Tool" for windows (v2.58 +) from downloads page
  3. Hold recovery button and press the reset key, the device should boot in loader mode, you should see it in the device manager
  1. In the folder you extracted the "Firmware Upgrade Tool", under "Android Tool" you'll find the file "config.ini" .
    edit it and change "Selected" field under "[Language]" to '2'. This is will change the tool UI language to English, Save and exit.
  1. Open "AndroidTool.exe" (extracted in step ii) and go to the "Upgrade Firmware" tab
  2. Press "Firmware" button and select the image you want to burn (make sure you are in "LOADER" mode)
  1. Press the "EraseFlash" button and wait. Output may look like:

Just reset the device using the reset button and it should be recognized in "MASKROM" mode.
8. After the restart press "EraseFlash" again and it should finish successfully now.

  1. Reset the device again and after the reset press the "Upgrade" button
  2. After about a minute the process will be done and a minute or two after restart you would see the device in ADB mode

Using Linux

  1. Boot to bootloader mode by running 'adb reboot bootloader'.
  2. The device should be recognizable in the OS Usb and red light should be turned on in the board optical port (dim red inside the port ).
  3. Get "Upgrade Tool" for Linux host from downloads page (newest one is fine).
    The tool is built with support to only 32-bit so run these command to make it work:
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libudev1:i386 libstdc++6:i386
  1. Run "sudo ./upgrade_tool", the tool should find the device.
    If not, make sure you are in boot loader mode and "lsusb" can see the device.
    Hit 'Q' when done.

  2. You can flash the image to the device using the command : "sudo ./upgrade_tool uf image.img"

  • Doing so will start printing the status to the screen and a progress bar should be printed.
  • If step failed you can try to first erase the firmware by running "sudo ./upgrade_tool ef image.img" and then try to upgrade.

    📌 Tool may be stuck, if message doesn't change for too long (20 minutes or so) quit and try again.


Follow the instructions on Wiki ADB page for adb connection and make sure 'adb devices' returns a device
Reboot the device, you should see the new Android installed.
