KOS Update | 1st Gen. Processors

Update via USB Drive

Step 1 | Prepare USB Drive

Any USB stick with 2 GB or more can be used. However, it is best to use less than 64 GB as USB detection issues might occur.

Plug the USB stick into your Computer. Make sure it has only a single FAT/FAT32 partition and MBR.

In case the USB drive is not detected by the KLANG processor or a KOS update does not start, make sure to follow this step-by-step guide to format the drive thoroughly.

Step 2 | Copy KOS to USB

Download KOS firmware files and extract the archive.

Latest KOS 1st Gen.
  • Copy the newest KOS version onto it – 2 files (1 x *.upd & 1 x *.bin).
  • Unmount the USB drive.
Make sure there is absolutely nothing else on this USB drive.

Step 3 | Insert USB drive to your Device

If :fabrik / :vier is running, turn power off first.
  • Insert USB drive to Front panel USB port and power on device.
  • The device will constantly look for an update on the inserted USB drive and start the update process automatically. Wait until the update process is completely finished.
Do NOT unplug or turn off KLANG:fabrik/KLANG:vier during the update process under any circumstances.
Some updates require the unit to reboot during the update and up to 3 times after the update is finished!

Since KLANG:vier has no display, the built in LED will indicate the update status. If your USB pen blocks the view on the LED, try to see the LED through the left ventilation grid. As soon as the LED turns BLUE you can restart KLANG:vier, SWITCH POWER OFF AND ON AGAIN. The LED turns purple when KLANG:vier is booted and ready for you again. See below for a details on the Status LED colors.

Step 4 | Check KOS Version

  1. Once the update is finished, connect with KLANG:app to your device.
  2. Go to Admin mode: Press and hold CONFIG for 3 seconds > Admin.
  3. Check CONFIG > INFO:
