No device detected, or readback protection may be set

Hi,

I am working NRF DK (NRF52840), when I am trying to flash the program in NRFGOSTUDIO from that it was showing some error that is "No device detected, or readback protection may be set". I tried in NRFGOSTUDIO, KEIL IDE and i have installed the latest version of NRF Command Line also. I have searched so many website, forums site, I tried all those things but its not working still now, Can you please help me on this, how to solve this error, Or else is there any Hardware issue will be there in DK board.

I am waiting for your quick response.

Thanks.

I should also mention that NRFGOSTUDIO is obsolete, but I don't think that is where the error of the unresponsive DK stems from.
