Here is the tool needed to flash the Oneplus 7 Pro - TMobile version back to stock.
If you converted to international already and want to go back or recover from brick, this is for you.


TMO MSM rar - Mega


The same steps apply to this as the other MSM tool.
You can follow the guide from my other post if needed.

Back on T-Mobile now thank's to this amazing Community. Some steps to help others.
Step 1- Download the file in the original post, create a folder somewhere you know where it is and extract the downloaded files to that folder
Step 2-Turn off your OP7 Pro
Step 3-Open the folder you created and right click on MsMDownloadTool V4.0.88.exe and select run as administrator, Once open uncheck sha256 check.
Step 4-Plug the Original USB cable that came with your phone into the phone.
Step-5-Hold the Power/Volume up/Volume down button until you see Connected in MsMDownloadTool, the instant you see Connected press start. You only have 5 seconds before it's too late so be quick.
Step-6 Once you see "Download Complete" in green in the Status of Communication box in MsMDownloadTool the phone will automatically reboot and you should have the TMobile splash screen and be able to set the phone up through the set up Wizard.

That's it you are done.

Will reverting back to stock relock the bootloader? I'm 99.999% sure it will.

But... Well the unlock token from OP still work? I'm tempted to try it when my token arrives tomorrow. Not like I can't make a TWRP backup of my current system and restore it after I go back to international. In theory.

Yes it reverts. If you are sim unlocked you can just unlock it or use the bin if not.
