Nrf51Dk not detecting

[Dhaval Dalvadi]

I have used nrf51Dk with nrfPPK before some days
now trying to flash nrf51DK but its not detecting any board
I tried to recover but not recovering it
I have already added jumper on p22 too.

LED5 is on and not blinking

Hi Dhaval,

After removing the PPK from nRF51DK, if the kit is still not responding to nrfjprog on the command line in any way, then there is a large probability that your kit is being shorted or you could have programmed it with something that makes it go to deep sleep too early (without a wakeup source) , hence bricked

Tried installing new jlink drivers
tried installing boot loader in nrf51DK
Reinstalled nrfgostudio

Still same issue
ERROR: Cannot connect to any nRF device. Please make sure a device is
ERROR: connected to the debugger and supplied.

then the device seems to be dead. It could happen if it was supplied with high voltage or if few of the pins are shorted with hand or any other conductor unintentionally.
