  2. Select Options -> List All Devices
  3. Select STM32 BOOTLOADER from the device dropdown
  4. Select WinUSB (v6.1.7600.16385) as new driver
  5. Click Replace Driver

This only needs to be done once.

Troubleshooting


If the firmware update utility fails to start on your system, an alternate way is to use these command-line utilities to update the X2’s firmware.

For Windows, you still need to install the X2 bootloader driver if this is the first time you’re updating the firmware.

Windows:

Driver installation

  1. Download and start Zadig
  2. Turn off your X2.
  3. Plug the X2 into the computer’s USB port.
  4. While holding down the TOP button, press the middle button to turn on your X2. (You won’t see anything on the screen – the screen may appear garbled but will not display anything)
  5. Select Options -> List All Devices
  6. Select STM32 BOOTLOADER from the device dropdown
  7. Select WinUSB (v6.1.7600.16385) as new driver
  8. Click Replace Driver

This only needs to be done once.

Firmware update

  1. Download X2-fwupdate-cli and unzip.
  2. Double-click ‘upload.bat‘ and the update should start. It should take approximately 1 minute, 40 seconds to complete, and your X2 will reboot automatically when it is done.

MacOS:

  1. Turn off your X2.
  2. Plug the X2 into the computer’s USB port.
  3. While holding down the TOP button, press the middle button to turn on your X2. (You won’t see anything on the screen – the screen may appear garbled but will not display anything)
  4. Download and unzip X2-fwupdate-cli-macOS and extract the files.
  5. open Applications -> Utilities -> Terminal
  6. In the terminal, type:  (press enter after every line)
    1. cd Downloads
    2. cd X2-fwupdate-cli-macOS
    3. ./macos_reset.sh
  7. A progress bar should appear and when it reaches 100%, the update should be complete.

Linux:

  1. Ensure that you’ve run the initial setup script if this is the first time you’re updating the X2.
  2. Turn off your X2.
  3. Plug the X2 into the computer’s USB port.
  4. While holding down the TOP button, press the middle button to turn on your X2. (You won’t see anything on the screen – the screen may appear garbled but will not display anything)
  5. Download and unzip X2-fwupdate-cli-linux and extract the files.
  6. run updatefw.sh and it should perform the update.
