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.
Clicking from Edge of Galaxy.
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.
HI Folks
I have heard that Samsung S7 edge on Verizon is by default GSM SIM unlocked. Is this correct ? dont we have to do any unlock or similar process to allow GSM sim cards to work from other carriers both domestic and international. Any limitations on this compared to a truly unlocked phone when talking of GSM/LTE features only ?
Thanks
Yes bro! It is unlocked in default. I am staying in India. I have imported s7 edge sm-g935v. It is now on android 7.p. But problem is, it has Verizon bloatware, Verizon apps, Verizon boot up logo, also say sin card is not from Verizon when I use local GSM sim card.
All the calls, messages, work perfectly. Problem is mobile data don't work properly. I tried setting internet configuration manually. Play store and apps work. But browsing internet on any browser don't work.
Let me know if there is any way to use firmware completely free from Verizon. It's annoying man!

I have heard the same, but I got S7 Edge from Verizon and is not unlocked...
so I heard this as well and randomly while giving payment asked them if I could have the 4 digit code to unlock... 5 mins latter I had code and on way it was really pretty easy =)

To remove the bloatware just install the Stock 935U firmware. That will remove all the verizon bloatware. Not to sure about the unlocking. I have heard both versions, that is GSM unlocked by default and it is locked and cannot be used on any other GSM network either.
So i have s7 edge verizon and i am currently in india. i got a vodafone sim card and it was working but the network wasn't stable. all of a sudden i cant access any network on the phone but when i insert a sim card i brought along fro africa i get roaming network.. can anyone assist? thank you

I have a SM-G935V (S7 EDGE VERIZON) USA. This is what I did, I put the Sim card in another phone (T-mobile) S7 edge, then copied the APN Network verbatim. Put the Sim back into my Verizon phone and been doing ok for almost 2yrs. The data does drop when you make or recieve a call or text message. Service is very spotty, majority of the time. If anyone knows if there is a stable rom for this situation, please let me know, I'm still on pb5

Verizon models lock out certain LTE bands from use that the network does not use, simply flashing the G935U firmware would be the best bet as it will unlock all available bands and remove all the Verizon carrier bloatware. When i first had my Verizon S7 G930V i was not able to get band 12 on T-Mobile, now that i flashed the G930U firmware i get all the bands and carrier aggregation i wasn't able to before. Same goes for the G935V and U models.

I just used my SM-G935V in Japan with a Y!Mobile SIM card for 6 months with 0 issues. Granted, I only used it for data, but it worked exactly as I would have expected. We did have to manually input the APN info, but the Y!Mobile sales associate helped me out with it.

I'm getting updates fine on both s7 and s7 edge, i have the latest March patch as well.
i had the same problems with verizon's s7 edge in dominican republic. pop up messages told me it's not a verizon sim card and data and internet would not work. then I downloaded sm-g935U international, carrier-less rom and installed it on my phone. all of the sudden my phone became a generic s7edge phone without the verizon crap apps. no more pop up and everything worked fine right from the beginning. data and internet work flawlessly and phone became a super phone.
Love my s7 edge.
Would you know if flashing the g935U firmware would also add LTE bands 12 and 17? I want the phone to be more
compatible with AT&T. Band 17 LTE is used in my area. My Verizon Galaxy S7 Edge G935V is at Android 8.0

I have the Verizon S7 Edge G935V. I want it to have more AT&T bands as it currently lacks band 12. When you say flash with the G935U firmware I noticed there are several versions for different carriers.
Would you mean flash the 935U firmware associated with AT&T? Or would I flash the verizon version of 935U? I am guessing the AT&T 935U for more AT&T bands, ??

I have this same question. My son has my old SM-G935V bought from Verizon, but it hasn't been connected to any service. I'm looking to connect it now that he's older, but I'm not paying the $XX /m Verizon wants to add a line for my kid, so I'm looking at Mint Mobile @ $15/m. I found these U firmwares:
Samsung firmware download - find All Official Android & Samsung Updates | updato.com
Are you looking for the official Samsung software to download? At updato.com, you'll find the latest Android device updates. Check on your own!
updato.com
But, which one? Do I use the Verizon one because it's a Verizon phone originally, or do I use the Tmobile firmware since Mint runs on the Tmobile network? Thanks.
UPDATE: Nevermind, I went with the T-mobile marked ROM and it worked flawlessly, at leas to connect to Mint, the service itself is garbage though so I'm going to try ATT ROM with Boost next.
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.

Hello! I've been out of the Android scene for a few years so I have a question that I can't seem to find the answer to by searches.
Can I flash the unlocked U1 firmware to a Verizon S10+ and use it on AT&T? I know I'll lose VoLTE and WiFi calling, but I don't really care about those. Mainly, I'm just trying to see if I can use a Verizon S10+ on AT&T. Ideally, I'd like to flash the AT&T firmware on the device but from what I've gathered, that firmware isn't available yet.
I had a Galaxy S8+ when it came out and I used Odin to flash between U1 and AT&T firmware so the process isn't entirely new to me.
A bit of background:
I'm looking to jump off of the dead iPhone train and hop back into Android with the S10+. I'm currently trying to sell/trade my iPhone XS Max in order to make the switch.
I have someone who is willing to trade me their Black S10+ for my iPhone as an even trade but their S10+ is from Verizon. It's unlocked but it's still running the stock Verizon firmware.
I just want to know what I have to do with this trade in order for it to work for me. I want to make sure I get a phone I can use. Any advice or input would be greatly appreciated!
Thanks for any help!
I'm not entirely sure if this will work on the S10+, I haven't tried it yet, but when I had the S8+(it was from Verizon as well), I'd take it internationally with a different sim card, it would just prompt me to reboot the phone and it would automatically apply the appropriate CSC settings. I was on stock VZW firmware as well and VoLTE worked (wifi calling didnt).
You should be fine either way though, people have successfully flashed the U1 firmware on their VZW devices for the S10+, so you shouldn't have any issues getting your AT&T sim card to work on it.

I wish Samsung included the BYOD update in the S10+, that would make it so much easier. I think I'm just gonna make the trade.
I've read through that thread and that's what I think I'm going to do. I'd much rather flash the AT&T version, but seeing as how it's not available, the U1 will do fine until it's released. I'll just need to switch to a different voicemail service in the meantime. lol
I got a Verizon S10+ and it is running build PPR1.180610.011.G975USQS2ASGB, I have confirmed that putting an AT&T SIM gives me network ability to call and what not. I want to flash the stock U1 branded firmware, is it okay if I flash G975U1UEU1ASD8 with Odin?

HEY I know have the same problem... Does it work.., I have installed the firmware and all so should I go for it.., waiting for your reply
I have Verizon unlocked phone and I'm able to use internationally where there is no Verizon, but I'm not getting updates so I have downloaded latest firmware should I flash it, also now I don't need any Verizon sim after flashing right ?
Yes you can flash U1 firmware to a U device and vica versa. The U means Universal, so you can flash AT&T, Verizon, T-mobile, or unlocked firmware to it. You gotta use the patched version of Odin though.

As Just changing csc without installing the system is more than enough. Even the company logo changes. Just look for the samkey program and you will see
