Will stock ROMs for various vendors work with a Samsung phone?

GZ99

I have a Samsung SM-J700P (aka Galaxy J7) phone. I got it unlocked and rooted.

I'm real new to this, so will some of you more experienced members offer their words of wisdom?

. Can I load T-Mobile stock ROM for this phone and get it to work? It is currently loaded with a Sprint ROM. My simple logic is that it's probably the same phone with slightly different Software for Sprint vs. T-Mobile. What do you think? What are the odds that it will work with a T-Mobile ROM?

If it does work with T-Mobile ROM, will I have to unlock and root it again? I think the answer is yes, but I'd like to hear from you guys.

Thanks in advance for all who take the time to reply.

I think I did enough research on the issue to say it probably wont work.
I wanted to find a way to enable WiFi calling. People on the internet say that if you can find another vendor (read Carrier, like t-Mobile for example) that has stock ROMs available and supports wifi calling, theny you can load their ROM and enjoy the benefits of wifi calling. Well in my case I have a J7 that has Sprint/Virgin Mobile $OM and although there is a T-Mobile ROM for a Galaxy J7, it has a different board number associated with it. That is to say the board I have is MSM8929 and the board for the T-Mobile ROM is Universal7850. This makes it highly unlikely that the $-Mobile ROM will work with my phone.

If anybody has a contrary opinion, please let me know. Otherwise I will pursue 3rd party VOIP apps.

Thanks again
