Could you try to execute the following nrfjprog command and see what it returns:

nrfjprog --ids

[quote userid="92648" url="~/f/nordic-q-a/67561/unable-to-connect-to-nrf52833-dev-kit/277005#277005"]I don't think the problem came from micro USB connectors because the board is still supplied by this connectors!!![/quote]

The power and comms are on different pins - so it is possible for the comms pins to be damaged while the supply pins are still intact.

Hi,

Have you exposed the DK to any voltage/current that is outside of the specifications?
Have you soldered or cut any of the solder bridges on the board?
How is the switches on the board configured? Could you upload a picture of the DK that clearly shows this

OMG. Sorry for my late reply. I have checked all of your list. It's okay anyway. About what awneil said, I don't think the problem came from micro USB connectors because the board is still supplied by this connectors!!!

That's a good checklist!

Are you able to update it to include checking that the micro-USB connector hasn't been damaged, or come loose?

This is certainly not an uncommon issue with micro-USB connectors!

I've certainly had it happen (though not on a Nordic kit - yet...)

😞

Those micro USB sockets can be a bit fragile - look very carefully in case it's come loose from the board...

I have no idea. I just plug off the caple and then when I put It back the LED 5 didn't turn on for me :(
