Is there anyone out there that has a week 45 phone in the US that doesn't have the new bootloader?? If yes maybe you can help me decide if I should open my new phones.

I have one that reads 7t745***WH8 and 7U744***WH8

If your serial is similar and it had the old bootloader I would love to hear about. I know its annoying but please take a min to help me out
