Unable to flash DK after cancelling prior flash mid-operation

[bramS2M]

After cancelling a flash operation to my nrf7002DK (PCA10143 1.0.2), I'm unable to flash my discovery kit again. I have tried both the regular west flash for our application, as using the nrfconnect desktop app to try and program a simple hello world back to the dk, neither sadly worked. I was unable to recover with west flash recover, nor nrfutil device recover.

using "nrfutil device recover --log-level trace --log-output=stdout --json" I received the following log:

{"type":"log","data":{"level":"INFO","message":"nrfutil-device (version = 2.13.2, platform = x86_64-unknown-linux-gnu, classification = nrf-external) invoked with recover --log-level trace --log-output=stdout --json ","timestamp":"2025-12-10T11:37:35.168Z"}}

Flashing was working fine before this happening using the same virtual environment.

Additionally, I have also tried to recover both cores separately, the same behavior occurs:

Hi,

After the interrupted flash, it looks that FW on the on-board J-Link debugger got corrupted or erased so in this case you can try restoring it using the J-Link Configurator app, which is installed automatically with the Jlink drivers (www.segger.com/.../).

Open the configurator, select your DK’s J Link entry, and choose Update / Restore firmware. After that, power-cycle the board and try flashing or recovering again. Hope this resolves it.

Kind Regards,
Syed Maysum

That did the trick, thanks!

Good to hear it worked.
