As the original post states, I will take any price (please be sensible though). Of course there is no damage from the reprogramming attempt.
Basically the Yubikey customization tool allows you to change the settings to whatever you want, however Gox yubikeys have a password set up on them which stops you from changing the settings. Don't know the password --> Gox won't tell you. So basically my attempt was finished before it started.
No point hanging on to two Gox keys when I only have one Gox account.
