Hey guys, I recently broke my s7e and got a check from Samsung to replace it. I'm looking for try cheapest way to do it and saw a deal on slickdeals with a comment that said:
The Sprint galaxy S7 edge can be flashed to be the 935U version, not sure about the non edge version. All S7 and S7e sold in the US have the same hardware though, so the Sprint version does already have the hardware for the 4x4 MIMO, flashing it to the U version if possible should be enough to put it on parity with the T-Mobile version on most things software wise (including Wi-fi calling I believe) and 100% on par hardware wise.
Yes just root, install custom recovery, download a tmobile rom that has built in aroma installer and you then own a unofficial ALL bands and services for tmobile s7
Is this at all true?

Well you could probably ODIN to different firmwares, but we have a locked bootloader and therefor no custom recovery. Could also try different ROMs on the exynos versions of the phone. But since they're different hardware versions I doubt you would get 100% functional software like wifi calling and VoLTE.

I thought that was the case. It was just really cheap and would be a great way to get another one if all I had to do was Odin the tmo firmware.

Yeah that would be a great idea. I know the phones are identical hardware wise. If I were you I'd do some more research to see if you could flash the sprint phone to tmobile through odin. I think it SHOULD work but having never tried I can't confirm.
I just flashed my Verizon 7 edge to the t mobile firmware and was able to use band 12, WiFi Calling and carrier aggregation. Should be the same for sprint.
Only thing I was told in the Verizon thread was that the firmware for t mobile is baseband 3 and the U firmware is baseband 2 so there is no going back until Verizon or U firmware is undated to baseband 3

Someone told me that Verizon was now in v3 with the latest update, is that not actually the case?

I believe you mean the bootloader v2/v3... not baseband. Baseband is referring to modem.

Yes. My fault. Bootloader
I would like to know if it's possible to flash the firmware for
T-mobile I'm looking to leave verizon I know that the Verizon variant does not have 2 of the lte bands that T-mobile uses can I use Odin to Flash the 935t firmware to get the band's or am I asking something that is not possible. Thanks in advance

The answer is NO you're asking firmware to replace/add hardware and that's not possible
I have a Verizon branded s7 edge and used Odin to load the 935U PI3 firmware. I am on T-Mo now and do have LTE band 12 working (validated with LTE Discovery). The research that I did found that the US variants have all the radios in them, but some carrier variants of firmware disable certain bands. By doing the 935U firmware, I also got rid of the notice on every reboot that I was using a non-Verizon SIM. So I now have all T-mo bands and no stupid SIM message.

I can vouch for same experience as SF-IT guy. I bought a G935V and flashed with G935U firmware via odin. Works on T-mobile, even wifi calling works. Currently on the latest PI3 version of G935U firmware. I would that you search the forum to see if you can flash the G935T firmware directly. The only downside of using G935U firmware is that the FM radio chip is not enabled in the firmware. I read that the all the carrier versions (September security patch and newer) of the G935 firmware have the FM radio chip enabled. I prefer the 935U version because it there is not carrier bloatware. Samsung bloatware is still there.

So what would the FM radio chip do? Just enable FM radios is all? Because if that's the downside then it's not a major setback as not too many people use the FM radio.
I don't think you can

You definitely can. All US versions of the S7 & S7 Edge are the same hardware and can be flashed to any other US firmware. (including the U firmware that automatically works on all 4 carriers)

So what you're saying is that flashing the U version firmware will unlock by default all 930"X" and 935"X" phones? As in it just unlocks the mofo and debloats some while you're at it?
What's the catch? It seems too easy

Bloat is definitely gone on the U firmware, which is great. My phone runs faster and has more free space too.
I think some carrier features aren't supported on the U firmware. On T-mobile everything works (VoLTE and Wi-Fi Calling), but I think AT&T might have some issues with those.
If the phone is SIM locked to a particular carrier, I'm not sure that automatically gets turned off or not when you switch to the U firmware. You might need to contact your carrier first to get an unlock code?

What if I got a temporary unlock from t-mobile unlock app and then flashed this firmware? Would it make it permanent? Seems quite possible, but I don't know if the temporary unlock actually unlocks the phone or just inserts a bypass that would disappear if flashed.

I unlocked my US TMo phone when stock, rooted, and am running Echoe - which has a glitch where WiFi calling sort of works (can receive calls but not make them). In the TMo forum, there are threads on U - your comments here are more specific to what I am interested.
Which U firmware are you on and are you rooted (is is updated to latest v4 bootloader version), and did you have to ODIN and full wipe with CSC or did you get by with CSC Home to preserve data?
Also, are you on U CP or did you flash TMo CP to get all the bands?.

Thanks everyone
I just purchased an unlocked S8+ from Samsung to use on AT&T in the U.S.
Do I need to do anything to the phone to be able to use all of the AT&Ts features/ VoLTE / get OTA updates timely?
Any help is appreciated!
I was not able to get any of the features on AT&T (including voice over lte).
The updates will not be coming from AT&T, they come straight from Samsung.
Basically you bought a phone that can work on AT&T, everything that got to do with the phone is not related to AT&T and not it's responsibility.

I got volte when I flashed carrier change but instead of doing the Guide for the T-Mobile I did the AT&T one at the very end And had no need to call AT&T
I'm little confused about between "Carrier switch" and "flash standard firmware" section in the follow post. Basically, not sure what file to use. I just downloaded the latest ATT firmware which includes AP, CP, BL, CSC, USERDATA files. should i just flash all of them using ODIN and use the adb line to "ECHO-> ATT"? is there a specific order i need to follow? thx.

If you have an unlocked Galaxy S8 u1 I followed these instructions from the beginning but instead of flashing the T-Mobile firmware at the end I flashed the AT&T one it works great for me with wifi calling and voice over LTE
https://forum.xda-developers.com/tm.../guide-how-to-convert-to-100-stock-t-t3615957
what i don't understand is they use G950W which is a canadian firmware. I am on US ATT network so i want to use US ATT fireware.

I'm not seeing the att portion in that thread..
and this flashing, does it wipe the phone and you have US att and the 950U1 and it then still worked for the USA att? (giving hd voice)? (need hd voice for s3 watch and numbersync to work apparently)
Do not use the stock Sprint software Numbers will not come formatted correctly when you receive phone calls.
For instance when you get a call it should show like this.
+1-808-123-1234
But on the Sprint software with a non Sprint Sim Card it will show like this.
+808-123-1234
So anyone who's saved in your contacts it won't show there phone number. And you also can't easily call them back from your call log.
And this also prevents blocked numbers feature from working correctly.
If you flash the unlocked firmware or you flash the carrier firmware of your choice this issues will go away.

Hmm, maybe this is why Google Voice can't send mms for me? I'm DSU'ed on G935P and using a Mint SIM (T-Mobile). When I try to send a mms from Google Voice, it says mms can't be sent to international numbers.

So if I flash the unlocked firmware. Will this affect my sim unlock that I just paid for?

Nah it wouldn't reverse the unlock status, I'm 200% sure it wouldn't change anything. I personally unlock and flash the latest G955U1 and G950U1 firmware AQH3 on 6 S8+ and 1 S8. It's works great on All US carriers, you can also flash each 4 individual Carrier firmware. I have flash all of the firmware each carrier release on my SPRINT S8's with zero problems. Enjoy
Were did you get their stock firmwares? Looking for,sprints and you used a modified Odin to flash?

Did you ever get your phone unlocked ?
I have a Sprint Galaxy S8+. It has been unlocked by Sprint. I am giving it to my daughter and want to change the firmware to MetroPCS firmware for her. I have the latest T-Mobile and MetroPCS variant firmwares. Do I need a special ODIN to perform this? I'm a little confused because I keep seeing discussions about modded ODIN versions for the Galaxy S8 and S8+
I have a new S8 (u1, XAA), unbranded unlocked, using ATT sim card etc. Is there any way to get the ATT features like wifi calling etc by flashing the ATT CSC or do I need to install a full ATT firmware?

You need more then that. U need to provide att with an imei number from an att phone that has wifi calling available. And from what I hear it can't be iOS, must be android.
