I just bought a used S7. I was told it was the Sprint version, but when I checked it it turned out to be a Rogers 930W8 with an Exynos 8890 which is a little faster than the S820 in my other phone.
Did I actually get lucky with this version or would the Sprint be better?
I would like to have it fully functional on Tmobile including all bands such as LTE band 12 and VoLTE and Wifi calling.
With Sprint the plan was to flash the stock Tmobile firmware.
Is that still an option with with the Exynox?
Do I even need full firmware and would flashing just CSC files to get me VoLTE and wifi calling.
Also, is the bootloader unlocked on all Exynos phones, and if so, is there an even better option than Tmobile firmware to give me everything I want?
Thanks
Flashing T-Mobile firmware won't be possible because it's developed the snapdragon SoC specifically, you'd brick the phone trying to flash it onto exynos, assuming Odin would even let you flash it at all.
Same goes for the CSC, you will need it for VoLTE and VoWIFI but you'd brick it trying to flash via Odin. Your best bet would probably be flashing TWRP and flashing the CSC zip if it's still being updated.

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.

No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?
Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?
I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint
Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.
So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.
flash not working?
i flashed the tmobile firmware and after its all dont i boots up does an update and then boots with all the sprint stuff still

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".
I was wondering if it's possible to enable VoLTE on an SM-G930F running BTU firmware on an AT&T carrier. Is there any way to get things like WiFi Calling and VoLTE on it, or am I just screwed since I'm using the international variant of the phone?
When I first got it brand new from Wal-Mart, it was running TTT firmware (from Trinidad and Tobago for some reason) and showed normal 3G, 4G, and LTE symbols on my status bar. Since I wanted to get the Nougat update early, I flashed BTU which switched the symbols to H, H+, and 4G. Does that have anything to do with it?
Thanks.
You're certain it's a G930F? And from Walmart of all places? Exynos isn't meant to be sold in the US.
If it's a G930F and you have TWRP you can flash the CSC tool in the development section which has the US carriers, and CSC is what enables VoLTE.
If it's a US snapdragon model you could flash the AT&T CSC via Odin without needing TWRP.

If OP successfully flashed BTU then it has to be a Exynos G930F, but I agree, most phones sold in the US claiming to be the G930F are modded Snapdragons faked to look like it, but they obviously won't allow a Exynos ROM to be flashed to them, so in this case OP has got a real Exynos
Could be the modem (CP) part of the firmware controlling which carrier services you can receive in your region, not sure I'd recommend flashing a US modem to a UK firmware though, unsure what would happen, although the G930F is pretty straight forward to unbrick as long as you can get back into download mode

Where is this CSC tool? I'm not sure what you mean by "development section". I have an Oreo G930F and I'm trying to get VoLTE to work with AT&T.

It hasn't been updated with the newer versions of Android so it's not really a thing anymore.
Next best thing is to download the entire firmware package for your carrier from somewhere like updato then flash only the home_CSC file. Although iirc this might now work if mixing and matching models, which is why the CSC flash tool was a thing.

The trouble is that the G930F was never officially released on US markets, so I can't find a US firmware. I'd gladly use another market's firmware if I knew it would support AT&T VoLTE and "LTE only" mode, but I have no idea how to figure that out!
So it turns out that I have the Canadian SM-G930W8 (as shown on the download mode screen), not the G930F (as shown everywhere else). Identical hardware, but I can only flash Canadian firmware.
Hello,
I am going to attempt to Flash my Sprint S7 Edge with current Firmware version G935PVPS8CRK1 to the Unlocked firmware of G935UUES8CRK1 as I have ported out of Sprint and need to enable all LTE bands for a different network now.
My questions are
Can this be done for the above firmware versions and will it enable all LTE bands if successful ?
In the SAMMOBILE page, there are different variants for the SMG935U including one for Sprint. I was assuming that all 935U variants would be identical, but I guess I'm mistaken. So, should I download the Sprint version of SMG835U or something else ?

Never mind, I was able to flash the G935UUES8CRK1 firmware. Also, in Odin I tried with the HOME CSC. Although Odin showed a successful status, my device went into a dm verity boot loop. Then I had to flash it again with the regular CSC file and it worked.
I'm about to do the same thing, were you able to use LTE and VOLTE? Or access other bands that didn't work while on the sprint firmware? Right now i have the sm-g935p and am using it with t-mobile. I can only get 3g speed and have voice working or LTE with no voice.
Yeah, LTE was working. Band 40 which was otherwise disabled in the Sprint firmware was open and LTE Discovery app confirmed it. Not sure about VoLTE.

Yes. The bootloader was updated a few months ago. There is a thread here with files and instructions.

My Uncle got me a verizon galaxy s7 from USA and now I am trying to run a 4G sim in it but it isn't working as VoLTE is not activating ( something called Advanced HD Calling) as verizon wants verification for it and as the device is here we can't do that
I was thinking of flashing an Indian Firmware on it
Will that help me ??
Or is there anything else I can do.
Please Help.
update 1 : I managed to unlock the bootloader
If it's a Verizon S7 it'll be a G930V which uses Snapdragon, you can't flash Indian firmware on it because India uses the G930F model which has Exynos SoC.
Also despite the bootloader unlock option being available and toggleable in developer options, it doesn't actually do anything on USA models. Don't attempt to flash custom recovery, it'll brick.
Your best bet would be to flash the unbranded USA firmware (G930U) which should rid the phone of Verizon, however it's unlikely that'd let you use local carrier VoLTE.
I can run an Indian Sim in this device its just that the Volte doesn't work
I can still make it work with an app from the provider
should i just make do with the app or try the unbranded firmware?
also the other s7 my uncle sent me has FRP locked and the seller can't obviously give me his gmail to unlock it.
Is there anything I can do to bypass it or do I have to send it back to USA? also i have no clue if it has OEM unlocking enabled
Im in US , i have s7 G930T (Tmobile), carrier unlocked. At some point i needed Polish cell number so i came up with idea to have Orange sim card (its Polish cell carrier) shipped to me and install on my cell so i can make calls to Poland over wifi calling. When sim came and was inserted into my s7 it displays ATT carrier and wifi calling is no longer there, but i kind of expected it , tmobile kind of sucks when you try to use phones from different carriers on their network or vice versa. So using odin i flushed it with xaa rom (it should be stock us rom), then with att rom, both times wifi calling was not there just like with tmobile rom. Then i tried to flash it with Polish stock s7 rom and then with Orange s7 rom, both unsuccessful flashes (partition fail).
Does anyone have some idea what i should try next ?
PS s7 is my old phone , currently have galaxy s10e (G970U version), funny thing is when i put new Orange sim into S10e everything works fine, wifi calling showed up without a problem.
Any help greatly appreciated. Thank you.
If I recall correctly VoLTE and VoWifi config is part of the CSC device firmware on the S7, which means you'd need to flash the polish firmware.
But the US model is a different SoC (Snapdragon instead of Exynos) which is why the flashing fails as it's not the right firmware for the hardware. I'm not sure there's any way around it.

Beanvee7, thank you for response, i kind of figure that much, I just had some hope there is a way around it somehow, especially since with my s10e i have same scenario ( us tmobile phone and Polish sim) and everything is working fine. Thank you again.
Looks like the S10 still has the CSC firmware, so I can only guess it no longer relies on carrier config in the CSC for VoLTE and VoWifi. But it's always been how the S7 has worked and commonly asked.
