T-Mobile (SM-G935T) firmware on Sprint S7 Edge (SM-G935P)? - Sprint Samsung Galaxy S7 Edge Questions & Answers

Got the phone unlocked and was wondering if it was safe to flash the SM-G935T firmware variants on the Sprint S7 Edge. Plan on using this phone on T-Mobiles network.
I know people have converted their SM-G935P to SM-G935U but I can only find the 6.01 version of that. SM-G935T has the 7.0 version (nougat variant)

You ever find an answer to this or give it a try? I want to try to move an S7 Edge from Sprint to T-Mobile soon as well.

Depends on your firmware version. If you go to your firmware version and go 5 digits back, this will give you the answer. If it is a 5 or 6, out are out of luck; if you have a 4, you'll be fine.

If your device is original from Sprint, it's impossible to flash any firmware because is a BINARY 6, and is the unique device on that, so... forget it.
Sprint change the binary to avoid users to modify the device, leave or erase their apps. Once your S7 have the May update/compilation, the device will never be able to root or unlock the bootloader again. or at least until the U variant change the binary to 6 also, but probably will never happend, Samsung hate their US products because of the FCC laws and the terrible rules and conditions of the carriers.
You can only install Original Oreo or downgrade to Nougat with May Update/compilation.
Otherwise sell or change your device for a U variant or an Exynos phone.

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.
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.

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 to verizon

I just picked up a used s7 edge from a at&t customer, every thing that I could find said once unlocked it would work on any network. I unlocked it via at&t, checked that it works on an at&t sim and Tmobile but it is not working on my Verizon sim and their techs can get it to work either.
Will an At&t s7 edge work on a Verizon network? if so how? Or should I find a different phone?
Thanks
Andy
That is an interesting question. I believe all the US based Snapdragon S7 and S7 Edges have the same hardware, so you would just need to flash Verizon or unlocked firmware over the AT&T image. That part is confirmed, as people have gone from V to U and A, and A to U and V. If I were you, I'd probably go for the unbranded firmware, but that's a personal preference.
The real trick is getting Verizon to properly provision it.
At&t is gsm and Verizon is cdma not compatible with cdma you need to give carrier imei that's how cdma works not just with SIM card

The US (Snapdragon) S7 and S7 edge share the same physical hardware. There is a better than average chance that if he flashes the U or V firmware, and can get Verizon to put on their network, it will fly.

Question: to convert from one firmware to another do I have to install U first? I want to convert my G935T to G935A to be able to use wi-fi calling. My phone is unlocked and everything works on At&t except for wi-fi calling (Or VoLte as I see it referred to often)

If this is your first device with AT&T to support WiFi calling, you may have to get a new SIM (or get your current SIM provisioned correctly).
So are you saying I don't need to install the G935A firmware?

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.

Flashing unlocked U1 Firmware on Verizon SM-G975U

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.
Edit: link to get the U1 firmware

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.
