Running a DFU - Nordic Semiconductor
If you want to run a DFU on your own application, you need to create your own DFU ZIP package, keys, and bootloader. See Generating custom firmware packages for DFU. There are two ways to run a DFU: using a desktop or a mobile device. The procedure is the same for the product example and for the DK add-on.

Help with restarting, debugging and size - Nordic DevZone
After that, you upgrade to the "normal" application firmware via DFU (2). Is that correct, and with the memory layout as suggested in this drawing? If so, then you are right. Then you subsequently reset and the bootloader enters DFU mode based on GPIO pin or other, and you update to the application, right? This should be straightforward.

Boot validation - Nordic Semiconductor Infocenter
The bootloader fails to enter the application because the bootloader settings are erased by calling nrf_dfu_settings_init() when the bootloader starts, causing nrf_dfu_app_is_valid() to return false. This only occurs if the bootloader is power-cycled multiple times in a row, otherwise works just fine and loads the main app as expected.
