Unable to program NRF52833DK

Yes,
I already tried.
1. I checked with different usb cable and cable are all fine, PC usb port is also fine.
2. I pressed and hold the IF BOOT/RESET button (SW5) and then while holding plugged the usb back in, kept button pressed for 5-10 sec i.e. Tried to Force the interface MCU into bootloader mode, BUT NOTHING CHANGED. The Dvice Manager showed nothing.

Can nrfjprog --recover -f nrf52 command run, even if board detected by Device Manager???

Despite of that I tried but I'm getting response as below,

C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin>nrfjprog --recover -f nrf52
ERROR: No debuggers were discovered.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.

IS THERE ANY ALTERNATE WAY TO FIGURE-OUT THE ISSUE??
PLEASE LET ME KNOW. I'm really Worried.

Thank You.

Dear Mr. Susheel,

I tried many times. BUT it's giving the same output as shown below:-

C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin>nrfjprog --recover -f nrf52
ERROR: No debuggers were discovered.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.

The 1st and most important thing is, my nrf52833DK board isn't visible in Device Manager. So how'd the command you mentioned "nrfjprog --recover -f nrf52" will work???

IS THERE ANY ALTERNATE WAY TO FIGURE-OUT THE ISSUE??
PLEASE LET ME KNOW.

Thank You.

Please check it with a different cable, it is not uncommon that the DK might have been shorted or fried by some ESD discharge.

Dear Susheel,
Thank you for your response.
But to RUN this command, 1st the board should be detected in device manager, right???
Does this command works even if the Device Manager isn't detecting the board???

Can you please try below from the command line from the folder where your nrfjprog is installed.

nrfjprog --recover -f nrf52

That should bring it out of any read locks if any. Try it a few times on failure. and if that does not work, then your chip is most likely bricked.
