Yes. That's what I'm talking about. Not carrier unlock. Bootloader unlock is blocked until the phone is fully paid off (if purchased under loan), and I believe T-Mobile requires a 40 day wait before bootloader unlock is allowed even if you pay in full upfront, and I think Verizon prohibits it completely. Google enforces these rules on their devices and requires the phone to connect to Google to authorize bootloader unlocking. It's an automated version of the manual bootloader unlock codes that some manufacturers do.
