See <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.tools/dita/tools/nrfutil/nrfutil_installing.html">here</a> on how to download and install nrfutil, or use the nrfutil I have attached here:</p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/4062.nrfutil.zip">nrfutil version 2.0.0</a></p><div style="clear:both;"></div>
