Just drag and drop the bin file to the JLINK directory

Can you explain the procedure on how to flash the bin file( J-Link OB-SAM3U128-V2-NordicSemi 170724.bin) in the interface MCU? Which software you use to flash the bin file in interface MCU?

Yes, I believe you are correct that there is an issue with the interface MCU. Like you have posted, you will need to drag & drop the correct interface MCU FW bin file to get the dk out of bootloader mode.

i am using nRF52 DK eval kit. I was just trying to look what are all different option in kit. The issue is resolved as i am able to reset the device now. But i think there is some issue with interface MCU, as if you entered bootloader mode, then we need to flash the J-Link OB-SAM3U128-V2-NordicSemi 170724.bin file again even if you haven't changed the code of interface MCU.

Are you sure the Power switch is set to ON? Can you specify which evaluation kit you purchased (e.g. nRF52 DK)?

If you're programming the device using a Nordic SDK example, I don't think a bootloader (or bootloader mode) are required..
