Also make sure the real target is powered up as VTG cannot be used as the power source for the real target.

If real target isn't modified then it is most probably not detected properly so you haven't probably connected VTG Detect and/or GND detect correctly. Can you use nRFgo Studio or NRFJPROG instead of drug&drop programming?

thanks for your help, I have connected the device as per above link. my computer has detected the board and able a D drive. I have dropped my file in that folder . The Nrf52 Board has changed with my program but the 3rd party board has not changed with the program. Can you pls guide me how to revert back the code from Nrf52 Board. And also the steps that I need to follow once I connect the Nrf52 board to 3rd party Board

The diagram here (devzone.nordicsemi.com/.../) may help too.

Have you ever used SEGGER J-Link or any similar JTAG/SWD programmer? You need to locate proper PINs (for nRF5x it typically is SWDCLK, SWDIO, GND and 3V3, other lines like SWO and RESET are usually optional), attach the probe and flash binary (typically intel HEX format or simply BIN) - or binaries - to target by SEGGER or Nordic tools. There are dozens of tutorials on the internet, several pages on Nordic Infocenter, dozen of Q&A on this forum. Please choose one and come back if you have troubles with some particular step.
