I wanted to share my experience with changing my Samsung Galaxy S7 from a Sprint phone to a T-Mobile phone.

I downloaded the latest Android 7.0 T-Mobile firmware. I decided to wipe my phone and factory reset, so I backed everything up and reset.

I used Odin to flash the phone. All went perfect. When I rebooted the phone I had the T-Mobile sound, logo and apps, as well as the proper configuration, LTE channels and all the T-Mobile apps. The reception was way better as well as I now had fast LTE. I checked for updates and the phone connected with T-Mobile. I'll have to wait until there is an update to see if it will actually do it.

So anyone in doubt whether you should try to configure your existing Sprint phone to work on AT&T or T-Mobile network, or just flash it to the proper carrier's ROM, I can tell you the benefits of flashing outweigh the extra work and frustration trying to properly configure it. And when all is done, certain carrier features will not work, you will be missing apps and no or slow LTE.

So my vote is for flashing the Carrier specific ROM. to the phone.

One other thing, make sure you know your Google password. Because you could end up in Google jail for 24 hours. It happened to me. I'm setting up the phone and get to the email address part. I enter the email address and password and it was wrong. I tried a couple more times, then decided to go to Google and change the password. After changing the password and verifying it was me with an email, I went back to the phone and entered them again. The phone took the correct password, logged me in and went to a screen that told me my phone was locked for 24 hours, for security reasons, because I recently changed my password. I called Google and they said there was nothing they could do. I read there are ways to get around it, but it was too much BS. So I turned it off, stuck it on the charger, waited 24+ hours, and fired it up and it let me in. It was still worth going through that because my phone is now working as it should on the T-Mobile network.

:good:

Happy to hear all went well, yeah its fair easy stuff and as long as you follow instructions, you should be fine. I use the SM-G930U firmware on a Tracfone branded S7 and no need for tracfone bloat and not located in the US.
[Sprint Samsung Galaxy S7 Questions & Answers] tempests:
I wish it was just as easy for my Spring Samsung Galaxy S6. I keep getting an error when trying to change it to T-Mobile firmware. I get a "secure check fail = bootloader" when flashing firmware on the s6. It is unlocked but I'm thinking it is due to the Sim card being Sprint. Because I changed my sim card in the S7 to T-Mobile prior to flashing. I'm not trying to hijack the thread. I just can't find a solution.
[Sprint Samsung Galaxy S7 Questions & Answers] micallan_17:
It's impossible to change the Sprint s6 to a T-Mobile s6. When the S6 was released, each carrier had there own model version of the S6 (hardware wise), this changed when the S7 was released since Samsung created only one model of the device and the firmware was the only difference. This is the reason that we can flash a T-Mobile S7 Firmware to a Verizon or AT&T or even the unbranded/unlocked Device that uses the Snapdragon 820 Chips in the US model S7. The S8 uses this same concept as the S7 i.e. the hardware is the same across all US & Canadian models I believe and the firmware is the difference.

You can brick your Sprint S6 by flashing a T-Mobile firmware actually.
[Sprint Samsung Galaxy S7 Questions & Answers] tempests:
Thanks for the reply. that explains why I kept bricking the phone. Lucky for me un-bricking is not a problem.

[Sprint Samsung Galaxy S7 Questions & Answers] pro_granade:
I did this exact process and just ended up with a Sprint S7 running T-Mo software that will only take Sprint sim cards, if I put in a T-Mobile sim it just tells me it's a invalid SIM.
[Sprint Samsung Galaxy S7 Questions & Answers] tempests:
More than likely your Sprint phone is locked to Sprint. This is very common, as the phone has to be unlocked. You will have to call Sprint to get it unlocked or pay some service.

Can you help me unlock my sprint galaxy s7

[Sprint Samsung Galaxy S7 Questions & Answers] oponewbie:
I have the same issue. Sprint even says the phone is domestic sim unlocked. but when I put a tmo sim in it, I get invalid sim. when I put sprint sim in it and use ICC Unlock I get a message saying the only ICC (sim) that can be used in this phone is sprint. However my phone is a Galaxy s7 Unlocked model SM-G930U ...but I took it to sprint with the BYOP program and they locked it to sprint when I activated it. I have been unable to get it unlocked since.
[Sprint Samsung Galaxy S7 Questions & Answers] tempests:
From what I understand Sprint locks them for protection for them. They will definitely unlock your phone, if no money is owed and you are out of your contract.

So basically you have 2 choices. Get Sprint to unlock it, which only requires a phone call. Or you can go to one of the many websites that will unlock it for you., for a small fee.

Like I mentioned, I decided to flash my phone with the authorized T-Mobile firmware, so I can get phone and firmware updates automatically, and insure my settings were correct. My phone was originally a Sprint phone. Now it shows it's a SM-G930T model.
[Sprint Samsung Galaxy S7 Questions & Answers] oponewbie:
My problem is this... MY Phone was a SM-G930U unlocked phone when I purchased it. I used that phone for the Sprint BYOD plan, Once I activated the phone on Sprint, Sprint locked the phone for both domestic and international use. I have since called sprint multiple times to get them to unlock my unlocked device, and they even say it is unlocked, but when I put a different sim in the device it says the sim is invalid, when I use the UICC unlock ability in the system settings it tells me that I can only use my carrier sim in the device and to contact my carrier to unlock the device for other sims. So sprint is giving me the run around to unlock the device. As for using a 3rd party service, no third party service can unlock a SM-G930U model since that model is factory unlocked in the first place and was locked by sprint when I activated it. I have tried to flash to T-Mobile and AT&T roms to fix the issue, gone back and forth from the SM-G930U software to the sprint software to try and force an unlock, and at this point it appears I am stuck on sprint rom software at the latest version, and can't flash back to SM-G930U or SM-G930T software due to sprints latest bootloader being newer, every time I try and reflash back to SM-G930U software now I get a odin error. I am about to just go file in small claims court against sprint for the full retail price of a galaxy S7 unlocked phone since they illegally locked my device in the first place.

But if you have any ideas on how to get the phone unlocked at this point when sprint says it is unlocked and it isn't and/or you know how I can flash from the latest sprint rom back to the latest unlocked rom without getting a odin error let me know.

I don't believe i can flash to any other rom right now as the sprint rom version (latest) is	G930PSPT5BQJ3 and all other versions Tmobile/AT&T/SM-G930U (unlocked) are all using bootloader version 4 and sprint is using bootloader version 5 on its latest firmware, which means odin will keep giving me fused errors as the bootloader is newer than what I am flashing.

[Sprint Samsung Galaxy S7 Questions & Answers] localphit:
A few months ago I had a very had time getting a sprint galaxy s6 to work with an ATT sim. I tried to go though sprint but it just wouldnt work...invalid sim. I was able to root the phone and unlock it and get it working on ATT. Fast forward to today. Called sprint once and got my galaxy s7 unlocked (phone paid off and account in good standing). Popped in ATT sim and everything works....everything. Few things to note: Before I put in ATT sim the phone was activated on sprint and in working order. I called sprint from this phone to unlock it. I put in the ATT sim. I then did a hard reset on the phone with ATT sim in. Connected to WIFI at phone reboot.

I was unsuccessful in unlocking a sprint note 5 with the same method. Note 5 is now my phone s7 is fiances.....s6 broke.

[MENTION=4360523]levilib[/MENTION] Here's what Phonescoop says:

http://www.phonescoop.com/phones/phone.php?p=5081

This translates to LTE 1 / 2 / 3 / 4 / 5 / 8 / 12 / 25 / 26 / 41 but it'd be good to get someone to verify this on the Sprint variant of the phone. I'm still wondering if the Cricket version of the phone has more bands including 25, 26 and 41
[Sprint Samsung Galaxy S7 Questions & Answers] TehPirate_:
I can verify the bands. I'm using the sprint variant on cricket atm, got it unlocked when i received it. I believe the cricket variant is on AT&T, dont quote me on that though. I'm only lacking band 11 for my area, which is the fastest lte band here, sadly.
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
So are you missing bands 7, 13 and 20?
[Sprint Samsung Galaxy S7 Questions & Answers] TehPirate_:
I have 7,not 13 or 20
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
Nice, so you have all the Sprint bands + 7. That's desirable. Now if that phone could be unlocked, I'd probably consider buying it although I think they make you activate a line with Cricket.

Would it be possible for you to screenshot all these bands? I'm very curious to actually see everything! :)
[Sprint Samsung Galaxy S7 Questions & Answers] TehPirate_:
Sure, note this isn't default priority. I altered priority to fit my area with AT&T better

Edit: there is a way to add missing bands on T-Mobile variant, not sure how on sprint without root due to restricted hidden menus.

I have an unlocked sprint S7. I'm using it on an at&t mvno. It has never had a sprint sim in it, as such all of the sprint bloat os still disabled or not installed. I'm having some problems in particular amazon music is disabled clicking enable in the play store does nothing. I've tried side loading it and installing the app through the amazon app store, as soon as it is done installing the app disappears. It's not listed at all under applications in the settings menu.

Hands free activation also kept activating every time the phone was restarted. I found a work around by disabling system update using the Samsung package disabler app.

Any suggestions?

[Sprint Samsung Galaxy S7 Questions & Answers] .dan:
are you in 'automatic' network mode, rather than 3g only? have you confirmed that your location has LTE, and if so, what band? is this band available on the sprint s7?
[Sprint Samsung Galaxy S7 Questions & Answers] UltraSubZero:
I am in automatic network mode, and I checked and I live in Dallas and we get LTE. Do you happen to know the LTE band for this area? Maybe I still have the wrong APN settings?
[Sprint Samsung Galaxy S7 Questions & Answers] Swarlos87:
I'm in the same boat here regarding a 4G LTE data connection and my unlocked Sprint S7. I spoke with an AT&T rep about why I only have 3G and was told there was nothing to be done....(don't believe that.).

So, my first question is can I eventually get 4G LTE on this phone with AT&T????

....and if so is this a fix that I can do myself or do I need to take it in to a repair store? In reading this thread I've gotten to my "Data Programming" screen using the "##3282# code but don't have a MSL code and then which bands to set as priority.

Thanks!
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
How did you get your Sprint S7 unlocked?

But more the point, it makes no difference if it's unlocked. Sprint's locked S7 does not support AT&T LTE bands so it makes no difference.

EDIT 17:00 PST - Two of AT&T's LTE bands do exist on Sprint's version but there's no guarantee either has widespread rollout and support on all of AT&T's network.

You need to get rid of this Sprint phone and buy the *just announced* unlocked S7.

[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
No sir, you are wrong.

Per the links above...

Sprint:

AT&T:

Sprint is missing 4G bands 7, 18, 19, 20, 29, 30, 38, 39, and 40.

AT&T does doesn't have 25 and 26.

Neither have 13, which is Verizon (and almost every other major market outside of the US)
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
According to the link below, they use 2, 4, and 12/17. The 700 MHz, which is band 12/17, is the legacy band they use primarily from what I understand.

https://en.wikipedia.org/wiki/List_of_LTE_networks
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
Assuming they've rolled out support for band 12 to most of the band 17 LTE access points, that might be right. But this is a recent development:

http://www.phonescoop.com/articles/article.php?a=12892

Band 2 is relatively recent for AT&T to use so support might not be very widespread yet.

Hi to all the comunity,

I have in my hands two situations:

g930p on PE1 when it goes offline (gsm signal) it never goes back online with signal. Phone needs to reboot or airplane mode ON/OFF in order to go online with GSM service.

g935p on PC5 this I downgraded it myself to unlock and done succesfully that with GCPROKey but it has the same condition than before with the signal.

Any thoughts.

Thanks in advance.
[Sprint Samsung Galaxy S7 Questions & Answers] myphone12345:
MFBI (band 12 support) on AT&T has been active for a while (at least a year).

The Sprint S7 supports all of AT&T's LTE bands except a couple of the CA bands (no big deal if you don't have those on their network).

I have used an unlocked Sprint S7 on T-Mobile. Works just fine. I didn't test it but I suspect VoLTE and wifi calling won't work although I do believe I have seen reports that say the AT&T variant's VoLTE does work on TMO). I did have to set up the APN manually.

Since all the US S7 variants are exactly the same hardware inside you could in theory flash a 100% Sprint variant to a 100% AT&T (or TMO or Verizon) variant but because of the locked bootloader you can't do that in practice.
[Sprint Samsung Galaxy S7 Questions & Answers] asuh:
Sprint only has bands 2 and 12 on the locked phones. It's missing 4 and 17.

This is why I posted in this thread about the unlocked S7 phones that were released on June 30. While I don't see Samsung providing a unlocked bootloader for any of their phones, if they did, this US LTE unlocked S7 would be a good first phone for them to provide a way to unlock the bootloader.

All of this talk is theoretical but there are benefits to having the Unlocked S7 vs. carrier locked even if bootloader unlock isn't yet provided (if ever).
