Getting a T-Mobile S7 & flashing or converting to US/stock firmware (SM-G930U)? - T-Mobile Samsung Galaxy S7 Questions & Answers

I'm thinking of getting an Galaxy S7 (T-Mobile version, SM-G930T) for my wife to replace her Nexus 4 which is on T-Mobile prepaid but my concern is "carrier bloat" that T-Mobile installed on the phone.
1. Is it possible to convert this phone to the regular US/stock version of the S7 which i believe is SM-G930UZKAXAA, I believe? I did some Googling and I see some discussions about "Odin" which I assume is the software to flash/convert the SM-G930T to the SM-G930U version?
2. Will Samsung Pay still work after converting it from the T-Mobile version to the US/stock version?
3. Any issues/disadvantages/problems to be aware of between the T-Mobile specific and non T-Mobile firmware to consider, in consideration of whether or not to convert?
Thanks, David

G930U and G935U firmware is maded for any US version that IS ALREADY UNLOCKED and want to convert it so you can remove all bloat preinstalled apps from the carrier and use the phone like it was G935F or G930F..
1- you can flash the U firmware on any US varaint Sprint, T-Mobile, ATT, but will REQUIRED a unlocked cell, and the bootloader had to be low or same as the U you want to flash.
2- will work, i already test it.
3- none, the U firmware is official from samsung and is created for that.. to be flashable on S7 unlocked for take it for overseas.
PS: its the same as g930F so mobile data icon will be enable, wifi call will not be there... and you can use bluetooh sharing.. etc.. but t-mobile features will be removed, if you have more experience you can enable them back.

I use a stock US galaxy s7 from T-Mobile, SM-G930T. From what I can tell it shouldn't cause any problems as it's not a custom Rom but stock firmware you can download directly from Samsung website.
I did some searching and found a few posts about sm-g930u extending battery life over sm-g930t with tmobile bloatware (can't say for certain as I've not tried myself).
In all it shouldn't harm functionally since it's stock firmware.
Hope this helps.

I extensively tested the U firmware before moving to T firmware (because I moved to the T-M side of Tracfone; the phone itself is ex-VZW); I have had exactly zero issues (with either U firmware or T firmware).
A tidbit; as a SM-G930T, you have access to both VoLTE *and* wi-fi calling - this was not the case for even VZW-native customers, let alone MVNO customers. (This has, in fact, been covered in the Verizon Wireless thread for the same phone.) It does not matter if you are merely using an MVNO (such as Tracfone). NO free Netflix, though. (Mice.)

Mintsim T-mobile S7 compatibility

My wife has a Verizon version of the S7, but our service just ended and she bought the Mintsim 12 month sim card today. From what I understand there was ONE version of the S7 made - that the software itself is what makes the phone activate the proper service antenna's. Since there is so many misleading topics - I wanted a definitive answer, can ANY S7 be activated on any service? If not which version of the S7 is the better version to work with? The Mintsim service uses T-mobile from what I understand, so if a verizon S7 doesnt work should I get the T-Mobile varient (it is the more expensive of the used versions on Swappa oddly) or ATT or?
You can flash any to the T-Mobile version for best results, or just flash the 930u firmware and have all bands.

Sounds good. If you decide to want it as a T-Mobile version all you need to do is flash that firmware in Odin.

Some advice/question on flashing S8 rom to get samsung pay/bixby to work on SM-G950F

I bought an unlock Samsung S8 on amazon. Looks like they sent me a TIM carrier branded S8 from Italy. I'm using it in the USA under AT&T carrier. So far everything work fine except for Samsung Pay, VOLTE, WifiCalling, and Bixby. I want at least Samsung Pay and WifiCalling to work. I see there is a guide to flash firmware to other carrier (https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817) but this seems to be for SM-G950U which uses a different CPU than my SM-G950F (Exynos). So my question is this
1) I probably cant use that guide because of the different CPU correct?
2) What are my options besides rooting.
3) Can I flash to some unlock firmware for SM-G950F that support Samsung Pay in the USA?
4) Will flashing to this firmware cause issue in the future. More specifically when there is a OTA software update, it will update and brick the phone?

using G930A variant on tmo network

I was given an S7 G930A variant brand new. I would assume that it's locked to AT&T. It runs 6.0.1 and has G930AUCS4APK1. I want to use it on tmo network and learned here that people approach it differently by either flashing G930U or G930T to it. What is the best approach? Thanks for your suggestion
is it that much unpopular that no one has any suggestion? I'm surprised.
If you want a bloat free experience just flash the G930U firmware. If you don't mind the tmobile bloatware, you can flash the G930T firmware. I use the G930U firmware on a Tracfone branded S7 since am not located in the US. For me the U firmware is best.

You would also need to unlock it if its network locked to AT&T, unlock before flashing.

Galaxy s8 active update outside US

Hi all. I have currently bought Galaxy s8 active to use it in Europe - Poland. It is a sprint / tmobile U variant. I have checked with samfirmware and since it's on G892USQS5BSF2 version - I assume it's a sprint version. It is hard to determine as they are both coded G-892U. Anyways the phone works well but the security patch is from last year and it's still on android 8. There apparently is an update to Android 9 but the phone won't update via OTA. And so are the questions:
1. Since they both are the "U" versions - can I flash the tmobile android 9 rom on it? I am asking because it's being used in tmobile Poland network.
2. If not, can someone reassure me that it indeed is a sprint version and flashing the latest sprint rom will do no damage?
3. Any idea why the caller id and spam protection option is grayed out? Is this because of regional limitation?
Thank you

Reflash AT&T 20 Ultra to Unlocked Firmware?

I've looked through threads of people doing the reverse of this. It's been a few years since I've had an android and was running nexus devices then. What's the process to flash an unlocked firmware on an AT&T locked 968U to the 968U1 firmware (assuming there aren't issues doing it)?
Are there any other pitfalls I need to be aware of prior to doing it other than the wifi calling?
If this is already posted somewhere else, please feel free to point me there. I didn't see any info about going from a carrier locked 968U to unlocked firmware.
Thanks in advance.

I just did this today went from TMB locked one to unlocked (For a family member) mine is unlocked. All went well no problems at all. Just download the U1 Firmware you want to flash and for CSC use home_csc (In ODin) so you can keep your data and probably the wifi calling feature too ( i did that all features are intact). Use the Odin and firmware from Ota and non Ota thread . Enjoy

What did you gain that made it worth it for you? Also, I'm on a Locked ATT/Firstnet Ultra and am wondering if flashing to an Unlocked Firmware would give me more control of my device.

If your on FirstNet I recommend that you stay on ATT branded software, I'm not sure if band 14 will work properly for you if you are on unlocked software. Thank you for your service!

You can get VoLTE back, but yeah, WiFi calling is not gonna happen.
https://forum.xda-developers.com/ga...to/how-to-activate-video-calling-lte-t4178819
The thread is for T-Mobile, but most of it works with AT&T devices as well.

I flashed the U1 firmware (ATJ3) onto my AT&T Note Ultra, then flashed the Home CSC from the AT&T U firmware. I have VoLTE and WiFi calling.
Help!
Hello all, I have a Note 20 Ultra 5g that is unlocked and I'm looking to flash the original ATT firmware for this device.
Having this unlocked version on Firstnet has been nothing but problems and I don't have access to band 14 or wifi calling.
I see this thread is a little old but if anyone could help me out or send me in the right direction I would greatly appreciate it!
I have rooted some of my older phones several several years ago so I think I could pick this back up pretty quickly. I know over the years things seem to get easier and have probably changed quite a bit since I've last done something like this.
Thanks in advance!

My comment was made before we were able to change IMS settings directly.
You can get it all now. VoLTE, WiFI Calling, RCS, Video calling...

AT&T hasn't released any "official" firmware for the Note 20 series.
Since Samsung firmware is multi CSC, just flash any firmware with the same build number as the AT&T variant and use your AT&T SIM card.
Go to this thread https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/
Make sure you know what device you have, U or U1. Then grab the appropriate version.
Fir AT&T U devices, N986USQU2DUCA or N986USQU2DUCA will work.
For AT&T U1 devices, N986U1UEU2DUCB is the most recent version.
