Flashing international Firmware

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.

If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??

I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.

...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

Firmware swap

I just bought the Verizon s7 edge at best buy for a good deal. However I am a tmobile customer. The people at tmobile were unable to get the phone to work with tmobile. So I went back to best buy to get my money back. The guy at best buy laughed.. he inserted the Sims card created a tmobile access in the settings and now it works with tmobile..cool...but...everyone my phone restarts I get the msg the Sims is not a Verizon sims..
Could I use Odin and flash the tmobile firmware and my phone still work? And recieve tmobile ota''s?

Mine does it to with att I just swipe it away because it dont effect anything

I don't know if you can flash a t mobile firmware, but you can flash a G935U firmware, once you flash U firmware you'll get noticed that all Verizon junk will gone, including that ****ing notification of Verizon SIM..
PD: I have a S7 Edge (G935V) with G935U firmware using a Mexican Carrier, BTW sorry for my bad english

Thanks for the help guys.. I guess I will just try and see once the official nugut comes out..
I will flash the T-Mobile and see what happens..
Worst I would have to do is reflash the official Verizon back on it..

Won't search for latest OTA updates

Hi, I bought a Galaxy S7 edge sm-g935a, and I'm using it here in Japan with other network. I'm just wondering why everytime I check for an update, it always says I'm on the latest firmware even when I'm like 3 or 4 versions behind. Even when I connect it to smart switch it also says I'm on the latest firmware too, and when I try to click on firmware upgrade and device initialization, it says "Galaxy S7 Edge does not support initializing, please contact customer support". What should I do to get OTA updates? Thanks

AT&T phones will not receive OTA updates if you're not on the AT&T network. You have to manually flash them. You could keep downloading the latest firmware and flash it, or you could download the U firmware, which will receive updates regardless of carrier.

I'd consider switching to the 935U Firmware, it kills the useless AT&T bloat, and you'll get OTA's

Thanks man, I tried searching for its latest firmware but none of it seems to work out, I found some on google and download it but when I tried to unzip the files, all the files that I've downloaded we're corrupted LOL. I'm now switching to 935U firmware :good:

My S7 edge won't update either. I seem to be stuck on the May 2017 security update (Build # G935AUCS4BQE1). I bought my phone from swappa.com last month. The seller had it listed in the AT&T section as the SM-935A. I can use it for the most part without any issues (no Wi-Fi calling, not recognized on the AT&T network). When I check the IMEI # with Samsung, they show it listed for Sprint. Any suggestions of what I should do? I know one option is to flash the 935U firmware.
Thanks in advance.

All US (Snapdragon) based S7 Edges are physically identical, so you can run AT&T firmware on a Sprint S7E and vice-versa. However, AT&T is well known for disabling features based on IMEI, which it appears they are doing for WiFi calling. Unfortunately, it appears someone converted a device that started life on Sprint, so unfortunately you may be out of luck. The only way to fix the problem that I am aware of is to temporarily switch your SIM out for an actual AT&T device (whose IMEI is recognized), and that supports WiFi calling and VoLTE, then put the SIM back in your converted S7 Edge.
Converting to U will definitely make the phone a LOT faster (and the battery last longer), but you are giving up on any carrier features period at that point. I personally felt that the performance and battery features were a lot more important to me than WiFi calling or VoLTE and I switched to U a while ago. I haven't looked back, but that's just me.

Thanks jshamlet. I did a chat with Samsung and they confirmed that my phone was originally setup for Sprint and that it has been unlocked. My fiancee has an AT&T branded S7 Edge, so I can try putting my SIM in her phone for a bit. Converting to the U is something I'll seriously consider. I had an unlocked Moto X Pure Edition, so I'm used to not having the Wi-Fi calling or VoLTE.

I ended up using Odin to flash the SM-G935U firmware to my phone. Once that was finished, it downloaded and installed the April - August security updates, so I'm happy now. Also, no AT&T bloatware.

Here are the Firmware updates for the ATT 935A.

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works
Hi everyone, I bought a Galaxy S10+SM-G975U (same model that all 4 major US networks use) that was sold as "Unlocked" without specifying that it is Sim unlocked, Network unlocked, or Factory unlocked. Most of the time unless a seller specifies which unlocked then it means the phone is Factory unlocked, I gathered this from 9 years of buying and selling Android devices so it's not just a guess.
When I got the phone Sprint OMADM pops up and tells me I have an incomplete activation, "about phone" told me it was Sprint Network Unlocked; after a week it now says unknown under "Brand" in the "status" section.
The seller said that when you buy a factory unlocked Samsung phone and put in a network sim card that Samsung then loads the branding (bloat in my opinion).
1. Is this true that Samsung could have loaded Sprint OMADM?
2. If true can I remove it so that I don't have to "Force Stop" it after each startup?
3. Is there any piece of software or database that I can look up the origin of this phone so that I can either change my eBay review of the sale and apologize for my mistake, or affirm that indeed the seller failed to disclose branding that he knew wouldn't go away when a buyer puts in an ATT simcard such as I have.
I've read one single thread by a user and not a Samsung official that claims that you can pop in a network sim card and then restart to change some software but I have not found even one more thread mentioning this phenomenon.
My background:
I've bought factory unlocked my Moto Pure X and a OnePlus 5 and neither did any ridiculous **** when I switched networks, so that's why I doubt this claim.

I bought a AT&T branded one for use on TMobile. It kept popping up errors. I flashed the unlocked firmware and it works great. I get unlocked updates and everything. You'll need to look on here but there's a walkthrough somewhere. But there are a few advantages for running the carrier branded version so you could flash the AT&T firmware instead. I wanted less bloat so I went with the unlocked one.
Think this might be the thread:
https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
That said after I did all this I did read there was going to be a update to the firmware which would do what you described.... Switching firmware based on the sim card. Never seen it happen on mine still on unlocked unbranded firmware. Maybe this phone is running old firmware prior to the update that implemented this?

not normal. LIke you, I purchased an 'unlocked' phone and when I powered on, it was a Verizon phone. I popped in my TMo sim, and it worked OK, but I would get the annoying Verizon popups reminding me that I'm on on their network. I installed the unlocked firmware and it went away.
But there's more: when the phone had a problem, I sent it back to Samsung under warranty (still unlocked) and when it was returned, I just installed the original sim and powered on. Now it seems to be a TMo phone, and when I look at the phone's software version, it shows TMB/TMB/VZW. It's been receiving OTA updates and I've disabled bloatware, so I'm OK with it.

Just to be clear I'm not going to flash anything. I'll just turn around and sell it. I need a stable phone for work and I used to mess around with flashing different roms and while it was fun it was a frequent activity and I don't have time for all the annoying trouble this phone has been. Thanks everyone.

Flashing rom is different from flashing a stock firmware. In your case the only way to be completely off from the previous network you are getting the notification from is to flash a G975U1 or G975U stock firmware which is unbranded or your network branded respectively and you are good to go. I switched my yesterday and am okay ?. I will be happy to assist should you change your mind
