You need to use the nRF utility application do do this as described <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v9.0.0/bledfu_example_image.html?cp=4_1_0_4_3_1_2">here.</a> E.g., nrf dfu genpkg bootloader.zip --bootloader .hex --application-version 0xFFFFFFFF --dev-revision 0xFFFF --dev-type 0xFFFF --sd-req 0xFFFE</p><div style="clear:both;"></div>
