Root 930U but use on T-Mobile w/Wifi Calling?

I have a stock fresh 930U (factory unlocked US variant), and I want to root it. However, if I do I need to use the AT&T firmware (from what I can tell). Is it possible to get the 930U rooted but still use T-Mobile's wifi calling/VoLTE?
Thanks for any help, I've read everything but can't figure out if this is do-able yet.

What are you asking? If you can flash att firmware on a U and still use T-Mobile wifi calling?
If so, why? T-Mobile is the only carrier that the U firmware supports wifi calling for

Switch Verizon S7 to T-Mobile

My wife and I are wanting to switch to T-mobile and give them a try since we would be saving about $100 a month.
I have a Verizon Galaxy S on Verizon. I heard that the Verizon S7 is unlocked, but some of the bands for t-mobile are turned off.
So here are my questions.
1. Is there a way to get everything turned on to work fully on T-mobile?
2. Depending on what is done to get bands to work on Verizon S7 will T-mobile updates be installed to the phone?
3. If the phone is flashed would that require manual updates as long as I have the phone?
4. Besides verizon apps would there be any things that would not work on the phone (Apps, features,...)?
5. I'm very techie, but have never flashed a phone. If this is necessary are there step by step directions to accomplish this?
6. Is there a way to go back to Verizon with the S7 if we switch to t-mobile and then decide to go back to Verizon?
7. Anything else...?
Thanks for your help!

All of the US S7's are the exact same hardware. You can use Odin and flash the T Mobile firmware and essentially have a T Mobile S7. If you want to go back to Verizon you could the reflash the Verizon firmware. You can search and get instructions on how to use Odin and use updato.com to get firmware. The T Mobile version is SM-G930T and Verizon is SM-G930V when searching for the Firmware.

Any problems with switching from AT&T to Tmobile on an H910?

We are thinking of switching to TMobile from AT&T. I see the devices are compatible. (Band 2, 4 and 12) And since I'm rooted, I don't have to worry about the OTA updates.
I assume if I take the H910 to TMobile, I will still keep on using the H910 ROMS, or at least the kernel, and if I want tmobile apps, I can prob just flash the bloat apps I would want from a tmobile ROM(apps only, obviously, not kernel etc..)
Is that correct? And what about any carrier specific features? Is it worth spending the $480(v20 on sale) for a new V20 from Tmobile? or would I be happy with an AT&T H910 on TMobile(Basically what problems can I expect)
Thanks!
John

What you want to do is totally possible. I have a (unlocked) H910 on T Mobile. Everything works fine. Running the NRD90M rom.
I don't have any of the T Mobile apps installed nor will I ever install them.

You sure you getting the right band 12? There is a, b and c I believe.

Questions on flashing Verizon firmware to a factory unlocked U1 Galaxy S8

Hello everyone,
I have an unbranded, factory unlocked U1 Samsung Galaxy S8 that I am wanting to switch to Verizon Prepaid. Currently, it's running on Tracfone with the T-Mobile network. Wi-Fi Calling is a must-have for me, but I've heard that it will not work on Verizon with the factory unlocked Galaxy S8 model. It currently works on Tracfone/T-Mobile, though.
Rather than going the extreme route of getting another phone, I was hoping that it would be possible to just flash the Verizon firmware on it in order to gain Wi-Fi Calling and other carrier features from Verizon.
Below are some questions I have about this.
1. Is this likely to work, or would I just be better off to get a branded phone?
2. Is the process as simple as it sounds on the SamMobile site? Or does the process involve something more like this?
3. Will I be able to receive OTA updates after flashing carrier firmware?
4. Are there any particular issues or pitfalls that I should be aware of before attempting this? (besides possible data loss, of course)
5. Will I be able to flash it back 100% to the stock firmware later on if I want to sell it?
6. Is there any other way to get Verizon Wi-Fi Calling while staying on the unlocked firmware?
Any input would be appreciated.
Thanks!

Been out of the rooting/flashing scene for awhile..

I'm still using my tmobile gs7 edge and I would like to continue doing so, but I will be going to xfinity mobile and they use Verizon...i bought a pair of burner phones to activate service...
I've read that simply putting the sim in wont work, that I have to flash the verizon firmware or "U" firmware, but I'm seeing a lot of bootloader 4,5,8 and such. I'm not sure what to do.
I'm currently on the latest tmobile oreo stock 8crj1 firmware. Is flashing still possible? Or am I sol? Anybody that can guide me in the right direction? I appreciate it

Well as an update, I was able to figure it out. But in the event someone else has the same issue.
935U firmware does not work with Xfinity mobile.
If you would like to use your own byod for Xfinity you will need to install the 935V version. (Verizon)
Everything works as it should.
