&lt;p&gt;&lt;span&gt;I have no knowledge of the&amp;nbsp;Arduino bootloader and&amp;nbsp;USB uf2 bootloader. It seems they do not support&amp;nbsp;nrf52840 revision 3.&amp;nbsp;See&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/pdf/in_141_v1.1.pdf?cp=19_21"&gt;IN-141&lt;/a&gt;. &lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Please seek help from the&amp;nbsp;&lt;/span&gt;&lt;a href="https://support.arduino.cc/hc/en-us"&gt;Arduino Help Center&lt;/a&gt;&amp;nbsp;or&lt;a href="https://forum.arduino.cc/"&gt;&amp;nbsp;Arduino Forum&lt;/a&gt;.&lt;/p&gt;
