Installing Stock T-Mobile ROM on AT&T N4

Hello everyone!
I really hope this doesn't break any rules, and doesn't automatically get removed! I just joined this website in hopes of getting some help regarding my girlfriend's phone. She has a Samsung Note 4 (SM-N910A) that was originally AT&T and was recently unlocked (no idea how!). She attempted to setup WiFi calling with no avail, and I assume its because everything on it is still AT&T. I tried to look into how to install the stock T-Mobile items, but I'm COMPLETELY lost. If anyone has some basic info I'd really appreciate it! Not looking to do anything else with the phone aside from that.
Thank you so much in advance!

To do that you need to flash T-mobile based rom and your phone must be rooted.but sadly you have AT&T variant and there is no root method available until now.
My best suggestion will be swap your device with unlocked T-mobile variant.
Hey AT&T Samsung Galaxy Note 4 who is still in Android Lollipop who can temporary root with KingRoot and who has a Windows PC.
If you have a computer, and if you can root with kingroot Use the batch file on a Windows based computer. And please create the unbrick image
Please, for everyone who has a bricked AT&T Note 4
And link me to the unbrick image
Heres the files,

Update my sim unlocked Sprint Galaxy S7 to stock Nougat will lock it again?

Hi guys,
First i need to say my android knowledge is less coz i am a guy who coming to android from iOS backyard. I recently bought a Samsung galaxy S7 in Singapore. I bought it from a generic shop(not from official Samsung shop)
Unfortunately I got to know from Samsung, this phone is a sim unlock phone which is originally belongs to Sprint USA. Currently It's running Android 6.0.1 and I can use my local Singapore sim. When I check the IMEI number from the web it says the model is "Galaxy S7 G930P". But within the phone settings it says the model number is "SM-G930F".
My question is, If i manually update to stock Android 7 by using Odin tool, will the phone is lock again? Help is highly appreciated
Thanks

Dear All,
I am writing with a lot of hope that someone would help me. I have a samsung galaxy s7 from at&t running right now on android 7.0. I got this phone from someone here in uae and it was locked. i tried paying a famous website to unlock it however they were unable to do that.
I request for help from someone to guide me how to root the phone and install a custom rom to unlock the sim card network so i am able to use this phone. I am an amateur however in a desperate situation to unlock this phone as i cannot afford to buy another phone. I know the risks of getting the phone bricked and i am ready to take the risk also. I have read the threads of muniz r however somehow those files are do not get downloaded. please if someone can help me.
