I just got my Pixel XL and it's already updated to Android 7.1.1 so does this mean I cannot unlock the bootloader anymore? I read somewhere that once you have done the update you can no longer unlock the bootloader and it doesn't matter if I revert back to 7.1 or 7.0 once the updates done it's been patched.. I didn't read that here it was on another android website i was just browsing around and decided I'd come here and ask and see if I can get a definitive answer.
