I got the same exact download at 181.52MB on my T-Mobile Note 8. I think the Note 8 gets the same update no matter the carrier since it contains each carriers firmware version. When I use an AT&T sim in my Note 8, it reboots into the AT&T firmware, boot up screen and all. If I ry a Xfinity Mobile sim, it reboots into the Xfinity version, boot screen and all. Each version says it's on the January update.
