Hello,
I am planning on purchasing the Galaxy S8+, but I think I'm going to get the unlocked version when it is released. My question is whether T-Mobile wifi calling would work or not on this version, and if it doesn't, then would it be possible to flash a T-Mobile rom on my phone without any problem? Would all T-Mobile features then work as if it was an official phone from T-Mobile? Also would there be any downsides in doing this? I know no one knows right now for sure, but I'm just asking based on the past and whether it has been done before with the galaxy s7.
Thank you!

I don't believe wifi calling will work on the US unlocked version, but if Samsung manufactured the phone's the same as the S7, I.E. same hardware, then you should be able to flash T-Mobile's firmware with minor to no problems (I just flashed AT&T firmware onto a Sprint S7 and the longest part was downloading the firmware. I didn't gave any issues while flashing. But there's no way to tell we have that capability with the S8 until the phone has been released.

If you flash the T-Mobile firmware, yes. You should even receive updates from T-Mobile as well.

It's been done to the S7 countless times. Check out the forums and you'll see. I'd say the biggest downside is carrier bloat and certain carriers block some features that Samsung included in the phones.

Quick background story, I've been using an HTC phone since the M7, and owned all the M Flagships and currently using an AT&T Branded M9. My wife is currently using a AT&T branded Galaxy S5. I really liked how open my HTC phones are, and all 3 of them had been able to be Fully SIM Unlocked, S-OFF, and can run any compatible ROM. The AT&T Branded GS5 of course only can use AT&T Software and its been a pain waiting on AT&T for patches and updates.
We're planning to replace them both with new Galaxy S7s and since we're planning to buy them outright, my question is which one should we buy? From I read it looks like all units have the same hardware, but the TMO variants seems to at least have the bootloader unlocked and should be SIM Unlocked if I bought it outright.
Our basic requirements.
- Sim unlocked(able)
- Bootloader Unlocked(able)
- Able to use Android Pay/Samsung Pay in the USA
- Rooting is nice but not required, and as long as it don't break A.Pay/S.Pay
- Able to work on AT&T with little or no issue (not missing any LTE Bands, etc)
- Open to get the Exynos model if can still support A.Pay/S.Pay in USA and elsewhere.
- Able to flash debloated or custom ROMs if needed
Its been awhile since i did any work on any Samsung Phones, so I don't know if its just as easy to flash ROMs and Recoveries like my HTCs
Thanks for any feedback on the matter.
You want the tmo version.

It figures as much. How easy or difficult is it to flash non-carrier rom? I know people are just started getting their S7s, did the s6 have any issues with flashing a clean rom and keeping all A.Pay and S.Pay?
There's no development currently on these phones since the sources haven't dropped yet since the phone hasn't technically launched, after mar 11 samsung will release some sources.
If you're looking to remove bloat on non-rooted phones your only options is this https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=en with a rooted rom android/samsung pay wont work.
Last year with the S6 I know for sure the international versions worked just fine with AT&T's LTE network. But last year all models used the same modem (Shanon 333), but this year the international version and the U.S. version are different and both have integrated modem and that throws in an uncertainty. I see no reason why the International versions worked last year with Samsung's modem but not this year, but until someone reports with first-hand experience I would not pull the trigger on the international version (Exynos).
I used SM-G920I (S6) and SM-G928G (S6 Edge+) and both worked flawlessly on AT&T's network.

Hmmm, still missing out on Samsung Pay eh, I wonder if there would be a non-carrier version of the phone we can get in the states with full support of all avaliable features and services. :fingers-crossed:
I'd like to bump this old thread for updates now that the S7 has been around for some time. I'm looking to get an S7, and it looks like the G930U variant might be the one to get now- is that right? I have the same requirements as the original poster, but I'll list them anyway:
-Able to work on AT&T with no issue (I read somewhere that some aspects of AT&T LTE are not supported? What impact does this have?)
-root is required (is it true that rooting prevents being able to encrypt the phone?)
-no bloat or bloat is removable (seems this is the main benefit of G930U?)
-SD card slot (seems like all US models have the SD card slot?)
Are there different versions of the G930U? Is this, for example, the right one: http://a.co/6QgYIxA ?
Thanks
Has anybody converted the Verizon Galaxy s6 to a T-Mobile one? I've seen it being done to an s7 edge but I don't know if It can be done to an S6

OK, well we have a few issues, number 1 is the bootloader, (but could someone explain to me why I can't you know, just flash the entire T-Mobile firmware package (including bootloader). number 2 is... well... hold on... **** it, ill try my best!

Lucky you didn't hard brick your phone. You tried to flash software onto a phone with different bands. CDMA and GSM networks don't work together. Verizon and Sprint phones will not work on AT&T or T-Mobile and vise versa. AT&T or T-Mobile phones will not work on Verizon or Sprint.
I've just bought a galaxy s8 plus on gumtree and just realised it's an American unlocked version. I wanted to flash EE firmware to enable Wi-Fi calling but I'm not sure if it's still possible using Odin as the uk phones have different chipsets.
Can anyone confirm either way?
Thanks in advance.

flash exynos rom on snapdragon , great idea if you want a brick. No joke, it won't work for sure. and if you flash the Exynos firmware with odin , including bootloader , it would be an hard brick, won't turn on , no more recovery or download mode, just completely bricked. So just no. and wifi calling is nothing to do with the phone but with your carrier and or your current subscription. if your carrier doesn't support wifi calling you won't have that option, so other firmware or even force to show that option changes nothing as you would have the same carrier .
and of course a csc (firmware depend of the country) works only with the right SIM card , I mean samsung block the phone if you use an American SIM card on a European phone. European phone works only with European SIM card and European carrier

Supports all 3 lte bands used by the UK, 800 1800 and 2600.
Supports all 3 GSM bands used by the UK.
Supports all 3 utsm bands used by the UK.
So in other words you were 100% incorrect
All of the high end phones have been quad band in the us for years.
I really hope this guy didn't just blindly listen to you and dump his phone for cheap.

The other person could not be more incorrect your phone works fine in the UK, along with every other high end us phone for the last like 10 years
I hope you still have it and didn't dump it for cheap because someone decided to open their big mouth without actually checking that their gut reaction has any basis in reality.
I don't know if there is full CSC support for the UK carriers, but all u1 phones are direct from Samsung and sim unlocked at the factory so you will be able to pop any uk sim in there and be able to use data/sms/voice etc no problem. What provider do you use? I can check my /system/omc directory and see if it's preinstalled by the standard is CSC package.
It's also quite likely that if not you can install the local CSC package that comes with exynos phones on yours. Not only are the other posters 100% wrong about the SD/exynos phones habing incompatible operating systems*, but even if there was a shred of truth to it the CSC package is mostly config files and images and whatnot anyway, so there little execution going on
*It has nothing to do with exynos or snapdragon they are both arm64 lol. If anything it's because Samsung kneecapped them to make sure it wasn't possible for licensing/snapdragon bootloader security or some other stupid thing.

Hi
Thank you so much for taking the time to write such a long and in depth reply.
I did reply to the guys post earlier stating that it the phone works absolutely fine on 4g LTE. I just thought he misunderstood me. Or vise versa. I've not dumped the phone because it works fine. Even if I can't get WiFi calling sorted I will still be keeping it. As long as I can still get updates ota I will be happy..
I bought a note 5 a few months ago not realising it was an AT and T model. That was a pain because it was stuck on lollipop and wouldn't accept any ota updates without an AT AND T sim card.
So I was just a bit wary of that happening again. But with this phone being unlocked I'm sure updates will be just the same as UK phones. (hopefully).
Just for the record my phone is running on E.E. carrier.
I've not checked if it's ever been rooted before.
How would I check?
Would a root checker app do this?
Thanks again
Simon.

I bought my Galaxy S8 from New York, after a while I realized that my phone is US unlocked version, now I live in UK and I don't get any updates for my phone at all since last year, I tried to flash it but it didn't work.
I'm sorry if this question is answered elsewhere but can someone please tell me if it's possible to enable VoLTE for T-Mobile USA on the exynos DUOS variant of the S9+ from Singapore? If root is required, can someone tell me what steps are required to get there? Currently I have 4G service as reported by speedtest but whenever I place a call all the data goes away.
Not a total noob but almost.
Thanks
Welcome to XDA! T-mobile US VoLTE is not yet working on the Exynos DUOS. We will need someone like TKKG1994 to work his magic like he did for international S8 version. The CSC for Tmobile is built for Snapdragon so it will need to be ported to Exynos variant. Most likely, you will have to root to get there when it becomes available. (Thanks to the awesome devs here...)

thanks for the info! do you know if att VolLTE would work in the US on this phone?
None of the US VoLTE would work until one of the devs figure out a way to integrate it. AT&T requires an AT&T phone to register for VoLTE so your best bet would be to get an AT&T phone. Someone had success on S8 Exynos by providing AT&T an IMEI from AT&T branded phone and then using the Exynos with "US CSC patch" someone had combined.

I think having a US model will always get you a better chance of VoLTE vs international Exynos model. I do not use AT&T or Verizon so I am not entirely sure but read a few other posts in this matter.
I bought S9+ from Samsung in Singapore. Brought to US, 4G works fine on Tmobile.
At first, I can't get 4G to show up. Upgraded software, still 4G does not show up.
Then I asked someone to send me a text message and I made a quick phone call. 4G showed up after that. I think it needs a synchronization.
Do you have VoLTE though? When you make a phone call does it stay 4G or does it change to H+?
On the Exynos variants you will get 4G data but not at the true data speeds and noVoLTE as I have noticed with my Korean variant. If you have already rooted and got things going you can follow a thread by a fellow international user on XDA who was able to achieve on his Note8.

When I call, I notice it stays 4G. Web surfing also on 4G. I notice it is a bit faster than my older S6.
Note that Singapore S9+ only has 4 bars signal strength, not like US version which has 5 bars. So you might notice it is lower signal strength but the dBm is probably the same. I have no way of measuring so I don't know.
Just FYI everyone, TekHD has forged a CSC flashable that gives all carrier features from Tmobile on international Exynos model. !!!

I guess this is it. Looks very promising. Will probably try it out soon. But I hate to loose Samsung pay and secure folder...but then again. How many times do I really use that anyways?
Will going through this TWRP process trip KNOX? If so, is there any way to make Samsung Pay work again?

You have to flash this zip with TWRP which I think needs root. I have been away from the scene since s7 edge but I'm pretty sure you need to root.

I've been using the unlocked Z Fold 2 but in need to use Wifi calling which is missing so I would like to know if it is possible to flash AT&T firmware to get Wifi calling? If so, how? Also, will I be able to switch back as well?
There is no AT&T firmware available, nor will there ever be, most likely, which is why my unlocked Fold2 sits on a shelf and I use the AT&T Fold2 that I purchased from AT&T. Either live w/out wifi calling or switch to T-Mobile or buy an AT&T Fold2.

Yes, it's absolutely possible. Has been since the Galaxy S8. All the US versions of Galaxy devices are identical. The only difference is the firmware, which is cross flash compatible.
Two caveats:
1. ATT firmware is not as readily available as other carriers, but it can be found. If/When Samsung upgrades the Z Fold 2 to BYOD firmware, that won't be an issue.
For now, check this thread for the ATT firmware:
F916U AT&T Odin Firmware Links
For those who don't know, F916U is the model number of all of the US carrier versions of the Galaxy Z Fold2 5G. The F916U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100%...
forum.xda-developers.com
2. If you flash ATT firmware to an unlocked device, you will NOT receive OTA updates. You'll have to manually flash each new version with ODIN. ATT is the only carrier I know of that does this.
