How do I reliably tell an unlockable bootloader from just a carrier unlocked device that may still have a carrier firmware that prevents bootloader unlocking?
I’m not sure I understand your question. If you’re in the US do not buy a Verizon model. If It’s a Verizon model there’s nothing you can do with it. If the phone was purchased directly from Google it will be unlocked. It should be unlocked from most carriers I believe.
Buy a used one, that’s what I did. Google didn’t make a dime off of me.
