You can try doing this.
What I would do is get cloudystock rom and unzip it. Inside of it you will see a folder named variant. Get copy all those files from your variant folder and paste/replace on a tmobile rom with 7zip.
There you will have a tmobile rom with all the requirements from your model to work.
Let me know if this helps. Good luck
