You guys are going about changing your CSCs the hard way.

Yes it's a FRP tool but it also has one click CSC change (download speeds for firmware is pretty reasonable too). Image attached - T-Mobile U Model S22 and the CSCs built into the T-Mobile ROM. I got about half way through this thread and saw the same question a lot - no it won't trip Knox. You don't need root. You don't need to flash a firmware, you just change it to whichever is the better of the bunch and the OTA updates will start rolling in.
There's also a button to clear any bloatware should the CSC you choose include anything carrier or region specific that is considered garbage.
You just need to enable USB Debug Mode, or some phones you need to manually open the dialler and enter *#0*# to fire up ADB through test mode. If you've got a Verizon phone, there's a button in that tool to enable test mode as it's disabled.
Example: I've got a Samsung Live Demo Unit in a certain model from a certain region that actually ships with IMEIs, they're just disabled by the chosen CSC (not in the list, doesn't display as an option in the app either so you don't accidentally choose it) - as well as the power saving modes and charging to 100%. They only need to have the CSC changed to another country/region in the same Multi CSC firmware to be a full retail unit (as well as Demo Mode disabled with a password).

In regards to flashing firmwares from outside your region - the limitation is on your CPU. A series and M series Samsungs all use Exynos, so you can flash U, U1, F, B firmwares on them (probably more). U, U1 use Snapdragon and are interchangable, N and 0 use Snapdragon but I've never bothered to flash a N or 0 firmware on a Snapdragon phone to see if they are interchangable. E and B are interchangable (or F and B previously). If you are going to hop between models you MUST be using Patched Odin to skip the SHA256 check.
So yeah, you can absolutely flash U1 firmware onto a U device, I bought a lot of 10 of them that are locked to T-Mo are are all on U1 now. If only unlocking them for use in Australia was as easy as swapping firmware and CSCs
