Hi, 

Not sure I understand your situation or not. 

But , after loadfile command it shows load failed : Unable to open file 

Which file do you load? 

If you are using SDK 15.3, I would suggest you refer to BLE Secure DFU Bootloader. The test images are under nRF5_SDK_15.3.0\examples\dfu\secure_dfu_test_images\ble\nrf52832

[man]

loadfile is a jlink command and the file I am using is merged hex file ( bootloader + softdevice (6.1.1) ) . 

Anyways I got an alternate solution for this ( by using nrfjprg ) which is working fine for flashing DFU bootloader and  softdevice .
