It seems I’ve managed to brick my just-acquired Nitrokey Start. I feel such a noob here…
I’ve read the note about the admin/user pwd:
(Please be careful to change admin PIN first and user PIN second! Otherwise the admin-less mode got activated, see [this instructions](https://www.fsij.org/doc-gnuk/gnuk-passphrase-setting.html#) for further information.)
I figured, who cares, I have too many passwords to remember in my life any way (as evidenced by me bricking it) and went user-only mode.
I’ve also read the note about old firmwares:
Firmware version 1.2.5 or below: In case you forget a PIN or enter it wrongly three times you need the reset code to unblock the PIN. Otherwise the device wouldn't be usable anymore! Therefore please set the reset code as well when initialising the key!
I figured this does not apply to me, since I have 1.2.10, and have not created any reset code (same reasoning again)
And… I of course managed to enter the passphrase wrong 3 times, setting the key url, of all things.
And of course factory reset does not work either, due to
sending card command dummy select failed: Conflicting use.
I have read about this issue in another thread but that supposedly was caused by an old firmware.
So what now? Trash?
