&lt;p&gt;&lt;span&gt;What operating system are you using?&lt;br /&gt;Windows 10 Home&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt; Could I also ask what firmware you are trying to flash and if you are using the nRF Connect Programmer app?&lt;br /&gt;mfwnrf9160120 using nRF connect Programmer app&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Thanks,&lt;/span&gt;&lt;/p&gt;
