This is bad. You need to reflash the firmware. You said ...

It's hard to say. I used to not get n41 to save my life, now I can only get it to do Stand alone n41 and not NSA n41 with the available lte bands. No hardware or settings changes. Aggravating. It's got to be how Tmobile is setting up the towers and bands.
