IIRC you'll need to register an account, use their official unlocker, then wait 2 weeks before your device is allowed to be unlocked. It's supposed to be done to hinder 3rd party sellers that flash custom rom with ads on phones they sell.

Yes, that's something like the official process excuse. It doesn't actually work, because their server has been configured to reject all unlocking requests.
