Is there any terminal window or development IDE open at the same time? Have you tried from a different PC or do you have other board (e.g. nRF5340 or other nRF DK&#39;s that works with nRF Connect)?</p> <p>Have you tried to type &quot;nrfjprog --version&quot; in command line? And/or &#39;&quot;nrfjprog --recover&quot;?</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
