This was something that I noticed when some first-time users were giving Specter DIY a go at the DIY retreat, some folk would mess around and end up locking the Smartcard, but the current workflow was quite confusing both in terms of how everything behaves if you boot with a locked card, the messaging in the app as well as the documentation.

One question to discuss here is whether the "wipe device" button should be offered if the user boots with a locked smartcard, or whether this should be reserved only for the specific "session" where the user enters the wrong pin and bricks everything. (I think some information should be offered when you insert a bricked card, before anything is entered)

A second question is whether, given a user can use multiple different smartcards with the device, it's overkill to offer to wipe the whole thing if you brick a smartcard. (Perhaps just show a warning only, reserving the wipe process for if the device PIN is entered incorrectly the max number of times) Wiping on smartcard lock seems like overkill...

The current behavior in this PR is that a new, more verbose message is displayed when booted with a bricked Smartcard, with a button offering to Wipe Specter Device

Feedback from discussion, will remove the button to reset the device as this will confuse users, especially given that this factory resetting the specter device doesn't unlock the smartcard.

Will modify and update the PR

@Schnuartz please test!

I sacrificed a Smartcard and tested it.

This is the new text that is shown:


Now it also was not possible for me to press ok. I needed to restart. Not sure how it was before.

Don't have a SeedSigner with Smartcard
Applet yet. And I was not able unbrick the Smartcard:

@Schnuartz it's just the same process that you use to flash the applet on existing smartcard. It looks like your PC has multiple readers, so you just need to specify the reader in the command you are using. (Even if you specify part of its name with the -r argument)

Made a mistake here this is the actual error message. Not the one I posted previosly:
