Manually Updating X-CTU Firmware Library

  1. Download the current firmware that is relevant to the module.  Save this file (.zip) to a known location.  DO NOT unzip this file.  X-CTU is looking for a .zip file.
  2. In XCTU, from the Help (question mark) menu select “Update the Radio Firmware Library”
  3. Click on “Local File”, use the Browse button to select the current firmware .zip file you just downloaded, then click OK to start the update
  4. (You may be warned that the firmware is already installed. If so, click OK to proceed.)
  5. The firmware is then reinstalled, click OK to finish and you’re done!
