These threads have to many things going on, and now I am thoroughly confused. I just want to go to global from stock T-Mobile. I have downloaded so many things and I don't know what to use or not use. I have network unlocked and my bootloader is unlocked. I can enter fastboot and fastbootd.

There is no way to do it as of now. No one bothered making a conversion from T-Mobile to global with the 10 as there is no reliable MSM tool in case something were to go wrong in the conversion process. The most you can do on the T-Mobile version is unlock and root right now. I personally would love to be on global instead of T-Mobile firmware, but I doubt it will happen with the 10 Pro (although there is work being done on getting a useable MSM tool currently, so who knows).

All that'd take would be extracting your boot.img and flashing? Any issues with magisk?

For root? Just use the global patched boot.img and boot into OS, go to Magisk and perform a direct install. No issues at all with root on T-Mobile firmware. I've been rooted ever since they allowed us to unlock the bootloader and get our tokens.

Really all you should need to do to convert to global is unlock the bootloader, take the NA downgrade package, and flash it with Fastboot Enhance. Make sure you go to the partitions screen and search for cow and delete every one of them so there is room for the image and if you get any other errors, don't continue. Once the flash is successful (the bar will seem to stop, just let it sit for a bit and it will continue), choose English on the phone screen and go through the menus to find where to wipe the phone and then reboot.

There is a risk of a brick if something goes wrong so without the MSM Tool, this is at your own risk, but Fastboot Enhance doesn't tend to brick phones like fastboot scripts do as long as you stop if it gives you an error.
