Hi Pavan,
the steps to perform DFU with the sample DFU images in the SDK are given on this Infocenter page.

Hello, I am working on nrf52840 PDK initialy i erased the board and dumped uart application, now i transferred softdevice he file to my smartphone from this link E:\Nordic\Nrf52_840_PDK\nRF5_SDK_13.0.0_04a0bfd\components\softdevice\s140\hex , and using nrftoolbox app in DFU section i loaded the file but when i select upload it showing error like "DFU service not found", please help me to overcome this issue.
You need to flash both the bootloader (found in examples\dfu\bootloader_secure_ble\pca10056) and the S140 SoftDevice (found in components\softdevice\s140\hex) to your board in order to perform a DFU with the sample images found in examples\dfu\ble_dfu_send_hex\test_images_update_nrf52840.
