Got stuck with the getting nrf54h20 started guide with `NotAvailableBecauseProtection` error

[GalBrandwine]

Following the getting nrf54h20 started guide - https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/working_with_nrf/nrf54h/ug_nrf54h20_gs.html#ug-nrf54h20-gs

I got stuck after the UICR flashing step - it seems there a readback protection. I've tried to erase the UICR but with no success. How do I continue?

The operation was unavailable for some of the devices because they had readback protection enabled. These devices might be possible to unlock using the `recover` subcommand. See `nrfutil device recover --help` for more information.

Hello Gal,

Thank you,

I usually just use snipping tool and copy paste.

Yes, I see that you have the PDK (Preview Development Kit), and not the DK. The PDK doesn't work anymore (with the current NCS version and the BICR file that you programmed onto the kit. 

I suggest that you check with the person who gave you the PDK, and see if they can provide you with a DK instead. If you got the first one, I would assume you will get the other one too. To be fair, it was always very limited what you could do with the PDK in the first place. It was only a few specific pre-release versions of NCS, and it wouldn't work with the latest version of NCS, which you need for proper nRF54H20 support. 

Best regards,

Edvin

Hey Edvin, after switching to the DK, everything works properly thanks.
