Update running

The display backlight indicates whether the device is in bootloader mode or an update is currently running. When the update is finished, the updater will close automatically.

Alternative start (if the display is not usable)

If the display is not usable for any reason (e.g. an incomplete/failed update), you can start the update process like this:

  1. E-series: Disconnect the JunctionBox from the vehicle so the device is powered only by the PC.
  2. F-series: Switch off vehicle ignition.
  3. Start the NextGen Updater and select the update file (as described above).
  4. Connect the USB cable to the PC, unplug it again within 5 seconds, then plug it back in.
  5. As soon as the updater shows “Erasing…”, the update is running.

If it does not start immediately: unplug and replug the USB cable again.

Only for bootloader versions below 0.6

Install the USB driver (one-time per PC)

Important: Connect the display to the PC only after the driver installation is completed.
