What if I have problems updating?

Don't panic, the update process is safe, so you will always be able to recover your device

  • Restart Konfig. If your device reports a Cara version, the update was successful and you are done.
  • Try updating over a wired connection (rather than wireless)
  • If your device does not report a Cara version, retry the update process
  • If this fails, power cycle your device and try again
  • If this fails, put your device into fallback (from the button on the back of the device) and try again
  • If this fails, perform the device recovery process as below (only to be used in scenarios where device is not recoverable using the methods listed above)
    • Push the fallback button on device (should see lightning symbol or fast flashing led)
    • Download the latest firmware for your device type (zip file) directly from here
    • You do not need to extract the zip file as Konfig will do this for you.
    • From Konfig, select your device (will be in reprogram mode), and click on the Reflash button in the configuration tab
    • Click 'Select Rom' and point it to the zip file just downloaded
    • Check the Device Recovery tab at the bottom
    • Click Reflash (note - this will restore all settings to factory defaults)

What if I want to go back to Bute?

  1. You must first complete the Cara upgrade process once it has been started
  2. Put your device into fallback mode from the button on the back of the device
  3. Download and install the latest Bute LinnConfig application from the release download site
  4. Select your device from the list and go to the update tab. Select device firmware from the drop-down box and select the latest Bute firmware release and update
  5. Keep in mind
    • Cara control points will no longer work with your device
    • Your device will still have Cara fallback firmware (can not be reverted)

Why doesn't the right click menu work on Mac?

  • The right click menu available when clicking on a device in the list is not currently implemented in Mono v2.4 for Mac OS X. These operations can all be accessed through other means.
