Re: Recover Yubikey Neo with all applets erased?

That's what I figured. Guess that's what I get for playing around.

For future reference, is there a way to verify applet versions? E.g. how can I find what version of the PGP applet is installed on a card? That would help avoid such brute force approaches to clearing and updating card applets.

Mmm...

Probably bricked it. Yes, and you deleted all the standard Yubikey functionalities as well.

Recover Yubikey Neo with all applets erased?

2013-12-11T05:22:58+01:00

I've been playing around with the YubiKey Neo. I'm trying to load the latest version of the OpenPGP applet so that I can import keys to the Neo from an existing GPG keychain. I ran gpshell after building the 1.0.5 applet release, but it still wouldn't let me import keys for gpg so I figured it must not have installed/updated the applet correctly. In my cleverness to try to verify that I was in fact installing the applet, I figured I'd just delete the existing applets on the card, run the install again, and verify that the new applet appeared in the applet list.

So I used ykneomgr and the '-D' option to delete all three of the existing key applets. In hindsight, that was probably a mistake. Now I can't connect to the Neo at all using ykneomgr, ykpersonalize, or gpshell.

Did I brick my card by erasing all the pre-loaded applets? Is there any way to recover it?
