Well I've fat fingered my pin during setup so now my brand new ColdCard Q is pretty much useless. Didn't even get to actually use it.

I understand the intent of the security feature of bricking after 14 failed PIN attempts but because of that I feel just one confirmation is not enough.

I think ColdCard needs a third confirm, particularly because I find the keyboard on the ColdCard Q to be highly prone to keypress error even having small to medium sized hands.

A prompt to view pin would be nice too. I'm quite sure I remember my intended pin but I think I had an erroneous keypress.

I'm not trying to throw shade I'm just disappointed with my experience and that's mostly my fault.

Can you not reset it? Does it actually brick the device, or can you reinstall your seed on it?

No, 14 failed PIN attempts resume in a physically bricked device. There is no way to reset without the current pin. So it is not possible to bail out early and just start over with a new pin and import a wallet. If the user loses/forgets or just fat fingers the pin (and can't guess it) it's a $200 piece of electronic waste.

I believe the justification for this is to dissuade theft and sale of used devices.

I get the intent but I'm not sure it's worth it. I really want to choose OSS but I think I have to consider a different hardware wallet.

Thanks for the reply!

i believe this happens on new trezors with secure element

What? From my understanding, 3 failed pin attempts wipes the device, it doesn't brick them. Coldcards straight brick permanently after 14 failed attempts.
