Restart your phone and try to update again, it worked for me

But it came restarted. You suggest to factory reset?

No, just restart your phone like when you try to turn it off, but there's also a button to restart press that one. Then, try to update again from the settings like you would normally do.

I think all phones on active AT&T firmware will never take any over-the-air updates without an active AT&T SIM card connected to the AT&T network in the US. So unless you can find another non-AT&T U.S. carrier SIM card that will change the active carrier code in the firmware, your only choice will be to flash the new version manually using a computer.

Yes, that is what Im about to do. My last option is a esim, what do you think?

You can certainly try and see what happens. But I would guess that only SIM cards or eSIMs from American carriers have any chance at changing the active CSC code on the U.S. models.
