Installing AT&T firmware on unlocked Verizon S7 Edge SM-G935V

I've purchased an unlocked Verizon S7 Edge, model SM-G935V, but haven't received it yet. I'm an AT&T customer. The phone should work on AT&T's network since it's unlocked, but I just realized it'll probably still have Verizon-ified firmware, and might not work with certain AT&T-specific features like HD voice, video calling, or voicemail. How will the Verizon firmware behave when it's on the AT&T network? Can I install the latest AT&T firmware on this phone instead, using a similar method to what people are doing for the 935U firmware? I prefer a stock AT&T firmware rather than a beta or rooting. Thanks in advance!

There's another thread in this forum "Stock Firmware for SM-935A (AT&T)". Should I just flash that to my unlocked SM-935V, and essentially turn it into a 935A? I believe the hardware of all S7 Edge models is identical, so I'm hoping that will work.

I did this and applied the 7.0 update - and now I can't seem to revert to any other software. If I were you, I'd flash the U update and forget about carrier-specific garbage.

Thanks. Did you have any problems getting LTE data to work with your 935V once it was on the AT&T network? I saw a few mentions from people saying they could only get slower data connections, until they called AT&T to "provision LTE for their SIM" or something. I get the impression it's not enough just to have an AT&T SIM card - like the AT&T network has a registry of phone IDs, and non-AT&T branded phones won't be in it, and so won't get LTE data.
From browsing the 935U thread, it sounds like that firmware is receiving updates much more slowly than the carrier-specific firmwares. The U firmware also wouldn't provide the missing AT&T-specific features I was looking for, like HD voice or WiFi calling, so I'm not convinced it would really be an improvement over just keeping the Verizon fw. But maybe I'll feel differently once I actually get my hands on the phone and play with it - all I'm doing now is reading forum threads and checking my mailbox.

Honestly couldn't tell you. I'm on Verizon with my main device (S7e on U FW). I only flashed the AT&T FW (PK1) so I could flash the unreleased Nougat files.
Now, I can't seem to flash anything but an AT&T rom.
Also FWIW, the U firmware is getting updates slower than carrier roms, but it's still the better rom - untouched by the carrier's bumbling idiot of a dev team, no pre-loaded carrier junk you can't get rid of (only disable), better battery life and better performance.
More FWIW, I don't care about HD Voice or Wifi calling - both those are irrelevant to me.

At&t release today on 2/17/17 official update to Nougat 7.0 build BQA6 with February security.

I want to do the opposite - flash G935V onto G935A, with the intention of eventually being able to flash back G935A. Not sure if I could do this, though.

I've got my phone working now. The short answer is yes, as far as I've found, you can flash any carrier's firmware to your S7 Edge. There may be some limitations if the bootloader version on your phone is different from the new firmware's bootloader version, but fortunately I didn't run into that. I went from the Verizon firmware to the AT&T firmware and then to the unbranded 935U firmware.
But for best results, a branded S7 Edge should be used with the same branded firmware, and on the same network. Otherwise you may run into some problems, or certain carrier-specific features won't work. In my case, my Verizon-branded S7 Edge is unable to get Wifi calling and HD Voice (aka VoLTE) on the AT&T network with an AT&T SIM card, no matter what firmware version I use.

Really? That's strange. I successfully flashed V firmware on my A and HD voice & WiFi Capping are active

So you did the opposite direction of what I did? I've read that AT&T is more restrictive about these features than some other carriers, which is maybe why it didn't work for me. I can't find it now, but there was an AT&T community forums thread in which a rep straight-out said that those features won't work on a non-AT&T-branded phone or other unlocked "bring your own device" phone.
To be fair, I'm not certain HD Voice isn't working, since there doesn't seem be a definitive way to test for it. With the AT&T firmware, attempting to turn on wifi calling would give me an error saying it couldn't be activated on my device. With the unbranded 935U firmware and an AT&T SIM card installed, I don't even see an option for turning on wifi calling.

Why didnt my phone get nougat?

I recently bought my s7 edge directly from the samsung website at&t version and got it unlocked to be used on the tmobile network. I tried updating the phone to nougat but at&t software update would say that I am on the latest software which was 6.0.1. I even used a working at&t sim card because I thought maybe you need to be on their network but still it gave me the same thing. Finally I just used odin to update to nougat but I wanted to know if anyone knows why I was not able to update ota?

You are on the international version if you bought it directly from Samsung. They haven't released the international N for the S7 Edge. I know this is frustrating but you aren't the only one. If you can put up with ATTs bloat then go flash the Odin files, they have been released for ATT.

AT&T Branded S8 moving from AT&T service to Verizon

Hi,
I have read through a bunch of threads but have not seen my exact situation but I think I know what I have to do but want to get some advice from the experts here.
I purchased an AT&T branded phone an activated on AT&T a year ago. We needed to switch to Verizon so I got the unlock code from AT&T and switched no problem. As part of the switch Samsung has a BYOD feature that changes some of the software and menus from AT&T to Verizon. It was actually pretty cool because it removed the ATT apps loaded some VZW instead. Below is a link that describes the feature if you are not familiar:
Enjoy the Freedom of BYOD
So all is mostly good except I believe the menu change to update the firmware OTA is pointing to VZW and not ATT. When I run the update check it just says no updated needed. Looking at VZW they have updated their latest OTA version on August 1st here G950USQU5CRH1 so I know it is not trying to update to that.
ATT just released their version today August 30th here G950USQS5CRH1 but that is not updating either.
I will try this again over the next couple days to see if the updater is smart enough to find the ATT version but I am guessing I am probably in no man's land and will need to update manually using SamMobile or Updato or something else.
Any thoughts are very much appreciated.
Thank you.

I have tried a number of things like all the Verizon tools, Smart Switch, etc. and nothing will trigger a download.
I am downloading the only file from SamMobile that looks like the same version on the AT&T site but is says it is Verizon hopefully that will not matter. I will try to flash it with Odin and see what happens.

As an alternate I chatted with Samsung and they gave me the address of the a Best Buy in my area that will update the firmware for me. I guess some of the BB have Samsung techs in them. Kind of a pain but at least there is a back up.

Not sure if anyone is following this but I thought I would close this out. All options have failed.
Not even Samsung at Best Buy can flash the firmware since in their tool my phone shows up as VZW/VZW/ATT. So what I thought was a cool feature of the BYOD changing carriers only cripples the phone from an Update perspective, what a bad design. I would change carrier firmware as in some of the guides here but the problem is that I do not have G950U1 or G950U2. I have G950US which the older guides do not address.
I am either going to buy a prepaid ATT card but I hate to give those horrible people another dime or I will sell this phone and maybe just get Samsung branded like others in my family and they get updates from Samsung or go get an iPhone. I dislike iPhones a lot but at least Apple does not let the carriers screw around with their firmware.

Solved! Not sure why this site never showed up in my previous searches here or on the web.
https://samsung.firmware.science
Found the latest 2 OTA updates and applied them perfectly.

Well I can't say I've ran into this problem, but I to use ATT and am looking to eventually move to VZW, so I really appreciate your time and effort in making this thread as this isnt something I would have thought of myself. Also, that website is kick a**! thanks for sharing that

I was an ATT customer for 14 years on my wireless. The migration on the family 2 iPhones, 1 Samsung unlocked S8+ and my ATT S8 went perfect. I am the only one that had the firmware update problem because the other devices get updates directly from Apple of course and Samsung for the S8+.
My experience so far with VZW is excellent! For our family plan it was a little cheaper but our main reason fro moving was the network quality. Verizon in my area is so far ahead of ATT it is really shocking. Great call quality and data and coverage is fantastic. We had so many problems with ATT not sure why I stayed so long. They gave me a piece of junk Microcell to try and fix the issues at my house but even when we go to the ATT store that is 1 mile away, they do not even get wireless service in the store. They all have to use WiFi calling.
I have to really be impressed to recommend a company but VZW technology is well worth it for me. We will see how the rest to the customer services is.

What happened with the firmware you flashed with Odin? You can go to Updato.com and Download G950U or U1 firmware which is MUCH faster than the hours Sammobile takes. With newer firmware you can flash any carriers firmware (Go to Updato and download VZW firmware for example) because your phone installs the necessary files depending on the sim card you're running. Been that way for quite a while now.
Be careful with Firmware science as some of those builds aren't what is released so when a newer update does drop from VZW you wont get it again because you have a conflicting build number. Then you'll be back here asking why. Also, every time there's an updated firmware on FW Science you'll have to reinstall everything as flashing that update.zip wipes the phone post install. It gets really old.

Hi thanks for your input, I have 1 question to you, as I understand from your post you are talking about if mobile is already on VRZ firmware but have issue with OTA update? am I right? if not could you be so kind to tell me I'm on AT&T firmware G892AUCS3BRG1 (AT&T OREO Firmware) can I somehow switch to VRW or some other carrier? in addition, I have no Verizon sim and no AT&T sim as well I'm in Georgia and in our area, there are no such operators.
from my perspective it is good to have TMB firmware this would be the best option for me if it is possible
thank you in advance for your cooperation

Obtaining ATT Specific Functions On An Unlocked Phone

Hey Everybody,
So I've come to realize that my unlocked US S10+ on AT&T didn't have VOLTE or Wifi calling as options in the communication/call settings menus. this is pretty disappointing as it seems that using the unlocked phone with Verizon you get these features, and they make a decent impact on my use of the phone.
My understanding is if I flash the ATT firmware to the phone I would get the functions, so being an amateur I followed some simple guides to SamFirm AND ODIN, and downloaded the ATT CSC firmware for my model number. However after going through the Odin process and resetting my phone it is still showing the same Software information as prior to my installation, and I do not have the features.
I saw a thread on the board stating that the ATT firmware isn't available yet, so I'm not sure if what I downloaded was actually any different than what is on my phone,and my phones "Service Provider Software Version" did already have ATT in the description, which is a bit confusing to me.
Am I correct in understanding the only way to get the features would be through a firmware flash? And would anyone know if I had flashed the right firmware, and what the original firmware CSC would be for my model if I needed to revert?
My information is:
Model Number:
SM-G975U1 (S10+ ceramic white 512GB - Unlocked US)
Service Provider SW ver.:
SOAMC_SM-G975U1_OYM_ATT_PP_0018
R38M205LY2B

AP file name for reference:
AP_G975U1UEU1ASBA_CL15445662_QB22243196_REV00_user_low_ship_MULTI_CERT_meta_OS9.tar

If it's anything like the S9 was, you can't just ODIN the firmware/CSC. You'll just get the bloat with none of the features you want.

I've heard this as well. If you want those features on a Samsung phone, it has to be at&t branded. I ordered an at&t phone from Samsung since I make good use of wifi calling. It works fine on my unlocked P3XL but no dice on the Samsungs.

I have the same phone and service and when I went to update my imei they told me it could not find the phone. So I was without lte/4g for a day until I gave them a imei to a s8 active. Now I have data at least

So I have the same service provider software, on my unlocked s10+, however when I went into an ATT store and looked at a branded S10+
I noticed the service provider software version to be : SOAMC_SM-G975U1_OYM_ATT_PP_0033( thirty three at end),
so anyway to update the service provider version? does that come from the SIM ??

I have an unlocked S10 plus and I flashed the AT&T Firmware. I now have VoLTE and WiFi calling unlocked on my phone using AT&T. You need to make sure you flash the U version of the firmware, not the U1 one. Unlocked S10 is using the U1 firmware already so flashing that one again changes nothing.

I followed this thread https://forum.xda-developers.com/galaxy-s10/how-to/att-ota-ota-updates-t3909697
At first like you I downloaded the wrong version and nothing changed. I finally flashed G975USQU1ASBA and now have VOLTE/WIFI Calling and of course all of the bloat. But at least those two functions are working. Make sure that you complete a clean flash when I did a dirty flash I had problems sticking on the loading screen.

I believe you just need to call in ATT to take care those carrier specific features .

Which firmware can I flash with Odin to my S10+ Xfinity Mobile unlocked to get AT&T OTA updates? Currently have ASF7 flashed from the latest unknown firmware uploaded to Sammobile. I flashed w/o USERDATA. I just want to be able to get future OTA updates as I just switched my carrier from Metro by T-Mobile to AT&T. I was using U1 US unlocked firmwares on my Note9 & S10+ but want to use carrier perks now with AT&T.

What's with AT&T being the only ones to not release update files? You would think they all would be required to release them. More AT&T customers need kick up a fuss about it.

AT&T model and lack of updates

Hello. I wanted to ask about a problem that I have experienced with the S10+, which I know others have experienced as well, and hope there is a solution out there for it. I purchased the S10+ directly from Samsung, as they were offering a much better trade-in deal. However, I did purchase the AT&T version.
That being said..aside from the 2 fingerprint reader updates Samsung has issued, I have never received an OTA update from AT&T. Not a single one. I've had to come here to XDA, hope that someone posts the latest update files, and update using Odin. It appears that those files are being posted less and less. I'm "stuck" on ASGB update, with the July 1 Security patch.
Does anybody have any advice, or suggestions on how I could go about getting regular OTA updates? Or is there other recommendations on what to do here? I know there are many others that have this same problem.
Thanks in advance

Are you using an AT&T SIM card? If you purchased an AT&T model AT&T sends OTA updates whether you got it from AT&T or Samsung. If you aren't using an AT&T SIM they won't send you any OTA updates and Samsung only sends OTA updates to the carrier free versions of the phones.

Yes, using an AT&T SIM card. In fact, I went to the local store and requested a brand new sim, just in case. That obviously didn't work either.

All US S10+'s are the same. There is no such thing as a AT&T or Verizon phone on the S10+. That being said you can load any rom from any vendor on your phone. If you want to stick with AT&T and don't mind their bloat apps you can go to www.sammobile.com and download the latest AT&T rom and load it with Qdin. Make sure your sim card is installed when you reboot and you will have an AT&T phone when it is done.

Prior to August or September firmware on the S10+ was not all-inclusive. If you used an unlocked AT&T S10+ with a different carrier's SIM the AT&T firmware stayed rather than updating to accommodate the inserted SIM card. AT&T doesn't send OTA updates to phones running AT&T firmware if a non-AT&T SIM is inserted and as long as the AT&T firmware is installed AT&T is the only place you can get an OTA update from. You can't even update with SmartSwitch because it will show that you have the latest firmware regardless of how old it is.
I purchased an unlocked AT&T S10+ in early July that was on the February security patch and have a T-mobile SIM. The only way I could get software updates was to manually flash the U1 carrier free firmware with Odin. Immediately after flashing that firmware multiple OTA updates showed up for my phone.

AT&T offers a modded version of SmartSwitch that you can download from their website. You might be able to update to the most current AT&T firmware using their software which is called AT&T SmartSwitch. The standard Samsung SmartSwitch program doesn't access AT&T servers and won't update phones with AT&T firmware.

Why did I have to pick the carrier when purchasing the phone via Samsung? I could have selected the unlocked version, or any of the american carriers. I have the AT&T model. I see the logo when I boot up, and have all their bloatware apps. So that's not the issue. The issue is why haven't I received an OTA update, ever?

Your OTA updates come from AT&T since you are their customer and purchased the AT&T model instead of the carrier free one. You should really be asking AT&T why you aren't receiving OTA updates.
You might be able to update using AT&T SmartSwitch which you can download from AT&T's website.

I've tried contacting AT&T numerous times. They have no idea what the issue is. A quick google search shows the Smart switch tool in AT&T, but when you try and click on the link, it just takes you to a blank page.

Newer firmware is all-inclusive so you could download firmware with Frija and flash it with modified Odin even if it isn't AT&T firmware. The problem is that if you flash a build number AT&T didn't actually use on their devices you still won't get OTA updates from AT&T because their servers won't recognize the software version you are running.

I've tried contacting AT&T numerous times. They have no idea what the issue is. A quick google search shows the Smart switch tool in AT&T, but when you try and click on the link, it just takes you to a blank page.

Have you tried the standard Samsung SmartSwitch program? Maybe it can update AT&T firmware now but it didn't in the past.

If your phone is not carrier locked you could flash the U1 firmware and then you would get OTA updates from Samsung instead of AT&T. But you might not have access to some AT&T services like visual voicemail without AT&T firmware. AT&T also hates unlocked phones so it's possible Volte and Wi-Fi Calling will stop working. Some AT&T customers with unlocked phones were able to get the services activated by calling AT&T but success with AT&T Customer Service is hit or miss at best as you already discovered.

I have the same problem I have been able to update my S10 + AT&T through ODIN, because I cannot update using FOTA, I have the September security patch specifically "G975USQS2ASI6", I want to update to the October patch, but I do not receive the update via FOTA, because I do not use AT&T SIM but I am abroad using with another SIM.
I can Flashear with ODIN to the U1 version that is unlocked, I will not have any problem, I am not interested in losing any AT&T service because I do not use any, I just want to have my S10 + free of Bloatware and always receive updates via FOTA.
I found this Firmware is Sammobile "https://www.sammobile.com/samsung/galaxy-s10-plus/firmware/SM-G975U1/ATT/download/G975U1UEU2BSIP/298471/"
It is the most recent update of AT&T that they have on the official website, but it is G975U1 unlocked and not the G975U. If Flash this version will I have any problem freezing or ruining my phone?

No G975U1 and G975U firmware are interchangeable. If your phone was still carrier locked you might get a message asking for the unlock code but you aren't using an AT&T SIM so your phone obviously isn't network locked. I went from AT&T G975U firmware to U1 firmware with no problems.

Im glad I'm not the only one experiencing this. My wife and I did a bogo deal for the Galaxy s10+ back in March. My phone has recieved updates regularly, while my wife's phone is still on the March patch and security. She hasn't even recieved the fingerprint update fix. Tried calling AT&T about it and they were totally unhelpful. Told me I had to contact Samsung about that and that they couldn't help with the issue. Im debating on calling them back and trying to speak with someone more knowledgeable, but it might just be easier for me to update her phone manually. I haven't had to do something like that in ages, so I wanted to ask for some guidance on here.
Would i need to do each consecutive update she's missed manually? Or would just updating to the newest firmware outright do the trick?

Hey do you have the G975USQS2ASI6 ODIN files? I have been looking all over for it to flash it to my phone.

I just want to note, I am also in the same boat and it's INCREDIBLY frustrating. Both phones purchased in March with the BOGO deal, both phones stuck on the July 1st security patch. Supposedly what I've found after reading quite a bit is you can bring the phone to a local samsung repair center and they can flash the newest firmware, once you're up to date SUPPOSEDLY that resolves the OTA stuff. I don't believe it though.
