ATT S7/Edge (SM-G93xA) Can Be Downgraded From Nougat To Marshmallow - AT&T Samsung Galaxy S7 Questions & Answers

Since I'm not allowed to post in Flashing/ROMS I'm posting this here.
There has been quite a bit of questioning if the ATT S7 Flat and Edge can be downgraded back to Marshmallow from Nougat, And i have tested with USA Unlocked firmware and I can say that it works perfectly.
It originally started with me having issues with battery life and performance on ATT firmware on Nougat so I flashed the USA Unlocked version of Nougat and performance wise it ran MUCH better, However the battery life still wasn't there.
So I did some research where people were on the fence, some said yes while some said no. So I took the chance and downloaded the 6.0.1 firmware for SM-G935U and flashed it onto my phone with PrinceComsy Odin and 5 Minutes later it booted up fine.
Service is just as good as it is on ATT Firmware without the bloat, better battery life (by far) and MUCH better performance.
If I could post up the links, I would but I'm not allowed because I don't have enough posts.

I'm actually really pleased to see that this is possible. I do hope to see some links in the near future!

Sprint Variant Marshmallow ROM

Alright so i'm confused and reading around on here hasn't helped. I've flashed custom roms etc to previous phones no problem but with my S6 Edge+ i'm clueless now. I've got the G928P variant with G928PVPU1A0GD software version and i'd really like to get to marshmallow, i know there are still bugs etc i've read posts about battery drain and what not but doesn't really matter to me. I am rooted, have TWRP installed, but i'm just not sure what i need for 6.0.1. would anybody be willing to explain or point me the right way?
So far I have been unable to find any custom roms for g928p 6.x. There's little love for that model it looks like.

Stock firmware

Hi everyone. I am attempting to download the stock firmware for my Edge but can't find it. My phone has SM-G935A printed on the back. It is AT&T. The search feature on SAMMOBILE does not have that model. Is it ok to use a different firmware? It won't be AT&T anymore if I do, right?
The back of my phone gets really hot at times, especially right while booting. I wanted to try to root and put one of the custom ROMS on there but I am not doing anything till I find the correct Stock Firmware.

Check out this forum, https://forum.xda-developers.com/att-s7-edge/how-to/updated-935u-935a-live-links-pi3-t3501686. I'm running my AT&T S7 Edge on this firmware, WWWWAAAAAAYYYYYY better than stock AT&T. It has NO AT&T bloatware and it has the Mobile Data On/Off toggle listed in the quick toggles bar. Before you flash this on your phone check what build you're on in the "about phone" in settings. Here is the link with the latest stock AT&T Firmware, https://forum.xda-developers.com/att-s7-edge/how-to/firmware-pi2-s7-edge-sm-g935a-10-03-16-t3477246. Download to your pc in case you want to flash back to stock. Don't root, not really stable if you do and you can't install any other firmware / ROM unless you flash 935U Firmware. You can brick your phone or even trip Knox counter and that will void your warranty if you needed to return to AT&T or Samsung.

Hi and thanks. I don't care about warranty. I am thankful you explained that "ROOT" makes it unstable. How is it possible to flash custom ROMS without ROOT? Why is it so hard to find the dang firmware? I went back on that dang Sammobil to look for the stock firmware for a friends Verizon S7 Edge and I can't find THAT but NOW THE AT&T is there!!!!
It sounds to me like you are coming from an older phone that had an unlocked bootloader? Back in the day when flashing a new rom like paranoid or slimrom was the fun and cool way to differentiate your device from your friends. That was also a time when android was about as locked down as ios is now, and ios was still locking users into their own keyboard, and Samsung was scrapping with apple at every turn for the top seat in the mobile phone market. My how things have changed.
Android is much more open in some ways, there are far fewer things that most people need that require root access, and the device manufacturers have also begun locking down the devices much more. At least in the Samsung line, I don't know when the last US variant flagship bootloader was freely unlocked? The s3? I know I had a Verizon s6 that I could not even achieve root on following a certain point in the release cycle. Now we have all of these fun new terms like systemless root, magisk and engineering bootloader. It really comes down with what is your desired outcome from rooting. You can actually get a long way towards what you could do back then with a Samsung theme and the right apps.
I believe what ytaida is referring to is the ability to flash other s7 roms onto your phone. So while we may not be able to flash custom roms, anything with the correct bootloader can still be flashed. Typically with a phone that is only going to be in the same model, but Samsung kind of threw a curveball and created an incestual path for the s7. With their U firmware, (the 930U and 935U firmware shipped on the devices sold directly from Samsung as was mentioned above) you could flash an official version of that onto the tmobile, Verizon, att and a few other carriers hardware, and essentially change the model of the phone. From there changing it back was equally as easy, except changing it back could be changing a Verizon model into an att model. The radios were all the same. In this process a root exploit was achieved and some very smart (I am humbled by their knowledge and determination on these sites every day) folks started hacking together roms. So you will see some neat stuff done where you are never truly running as root, but there were modifications done as root somewhere along the line. Long story only mildly shorter. Be careful how far down the rabbithole you take this.
The next thing you know it could be 6am and you realize you've been downloading and archiving your own copies of stock Samsung firmware for the last 20 hours, for devices you don't even have lol..
Sure there are still custom roms out there, but as a US customer, if that is what you're looking for you are best off with a nexus device or One Plus.

Is not hard, just need to look in correct forum. BTW what firmware you want. You can find any firmware you want for both models. Just look harder.
On Edge of Galaxy
A few things:
1) There doesn't appear to be any physical difference between the 935A, 935T, and 935U. You can, as long as you mind the bootloader version, freely switch between the three versions. I'm not sure about the Verizon and Spring versions.
2) The 935A FW link is around here. I've used it, and it worked fine, but you will be on tap for a few OTA updates.
3) The 935T FW link is actually available in several places, but there is a direct link over in the T-Mobile S7E forum. I'm not really sure what it gets you that the 935U doesn't, though. It has less bloat than AT&T, about the same amount of branding, and AT&T still refuses to let you have access to the more advanced call features. It does appear to be a lot less laggy than the 935A, though - AT&T really screwed up the Nougat upgrade compared to everyone else. It will likely get updates faster as well, and T-mobile doesn't have provisioning checks for tethering.
4) The 935U FW link is also "stock" for this phone, and works much better in many respects (it's certainly faster and less laggy) The difference between the 935A/935T and 935U firmware is that the former two have all the software needed for AT&T/T-mobile specific features, like WiFi calling, VoLTE, Visual Voicemail, etc. The latter has none of those things, but it does give you back BT tethering, disables the checks for WiFi and USB tethering, along with a few other features that were disabled.
Thus, you need to decide what is more important. Carrier specific calling features or more tethering options and overall better performance and battery life.
Please check the ORIGINAL post date!!!
I got the help I needed MONTHS ago. For those of you actually attempting to help,
"THANKS".
NORBARB, as a "SENIOR MEMBER" I would have expected much more than that and again, please look at the date I posted that question. Of course the firmware has shown up now. I don't even own that phone anymore.
How do you determine bootloader version?

I'm interested in switching my unlocked Tmobile G935T to ATT G935A to take advantage of Wi-fi Calling. I'm not sure how to make sure I select the AT&T firmware that has the same bootloader as mentioned above.

I have yet to find a simple guide on "How to load a custom ROM on your AT&T S7 Edge"

I have yet to find a simple guide on "How to load a custom ROM on your AT&T S7 Edge"
I've traveled all over the interwebs, including this website and many others but have not found a simple guide for noobs. I read about CWM, TWRP, Odin, rooting, zip files, tar files, nandroid, backup ROM, root with app, root via computer, blah, blah, blah, blah....
All I know is that before I do anything I want to backup the stock ROM but before that I'm thrown all kinds of different tools and processes that one could use. For the noob it should be as simple as:
Step 1: backup your stock ROM and to do this download/install this tool then follow these instructions.
Step 2: root your S7 Edge and to do this download/install this tool then follow these instructions.
Step 3: find a custom ROM you want to install and to do this go here, here or here for you model and download it to your PC.
Step 4: flash your custom ROM and to do this down/install this tool and follow these instructions.
Maybe I haven't done a good job of searching so shame on me but I don't feel like given the effort I've expended thus far has yielded a straight and easy answer when it probably should be. I seem to run across a lot of promising reads/threads about this only to find that there seems to be so much more knowledge and experience with the SM-935F and not so much with the SM-935A variant. On top of it, it would seem that I'm told that rooting will or will not break Samsung Pay and other apps/features or that the flag will or will not permanently trip that shows the device has been modified. Very confusing.
When I'm presented with a tar/zip download I'm not sure to where I'm supposed to be downloading. To my PC then used Odin s/w on the PC to install via USB cable to the handset?
Can someone please point me to the simple guide to get this going...or am I gonna have to write it myself? TIA.
BTW, I should note that I'm coming from a S3 on Virgin Mobile to a S7 Edge SM-G935A to be used on Cricket Wireless (AT&T). Since I'll be on Cricket and not directly a AT&T customer per se I'd like to get rid of all the bloatware that AT&T was so kind to load up on the handset. Right now it has Nougat 7.0 installed: samsung/hero2qlteuc/hero2qlteatt:7.0/NRD90M/G935AUCU4BQA6
I am not sure if you have a US version the S7 (Qualcomm G935A) or the S7 non US version. But if you have the US version, we are out of luck. Our bootloader is completely locked and all those steps you pointed out are not available.

So it seems that with all USA Qualcomm versions regardless of GSM carrier you have confirmed we pretty much cannot do much other than load some other versions of firmware such the U version ROM? From what I read HERE this is the Marshmallow 6.0 o/s. I currently have the stock Nougat 7.0 firmware from AT&T on my S7 Edge. Is there a debloated 7.0 version of the U ROM available?
UPDATE: Never mind...I came across THIS THREAD regarding an unbloated 7.0 U-version. I see you were active in that thread so now I need to read the entire thing before I have more questions and if so I'll ask them there. Thanks!

If you still want to root your phone, you can follow this link and will let you get rid of all the bloat and root your phone, install xposed and all the mods for xposed. I have used the ENG.IMG version of root for the G935A over 6 months ago and it works great, given the choices we have.
Here's the link: https://forum.xda-developers.com/tm...eres-how-rooted-nougat-s7-edge-g935t-t3567502
I know the thread is in the T-Mobile section but if you read the first line, it says it works for T-Mobile, ATT, Sprint, Verizon, etc. It is a very long thread but if you read mostly the later posts from @Craz Basics and you will be able to see that it works really nice.
Good luck

Hey thanks....but I have another question now that I'm given choices.
Which ROM is better, the U 7.0 ROM or the T-Mobile ROM you just linked? And, why is it better than the other?

Ok the U 7.0 ROM is still un-rooted and bootloader locked. If you go that way, you get the U ROM with-out all the Bloat. But nothing more.
And the link is not really for the T-Mobile phone only. The ENG.IMG is for all makes of the Qualcomm chip. You install that and you are still with ATT. Still have all the things ATT provides like WiFi-Calling and other ATT things. And you can get rid of the Bloatware from the ATT ROM using different apps, like Titanium Backup. With the ENG.IMG you can root your phone and use all the apps that are available for Rooted Phones. One of the best is Titanium Backup. You can only use that one Rooted phones. If you have the U 7.0 ROM, you will have to use the same ENG.IMG to Root the U 7.0 ROM to get that OS rooted. And as I mentioned before you can use Xposed with the rooted phone.
If you are just looking to get rid of Bloatware on the ATT, there is an app for that also. Check out BK Disabler in the playstore. You can get rid of all the bloatware without rooting your phone.
Anyway, hope this make some kind of sense...

Thanks, appreciate it.
I'm really not planning on spending a lot of time making changes or tweaking the handset. I'm on Cricket Wireless therefore I don't see any value in the AT&T bloatware which is why I wanted it removed. My interest is primarily having the latest/greatest android version I can have without all the stuff junking it up. I'd like it to be as fast as is reasonably possibly but at the same time have reasonably good battery life. I'm coming from a Galaxy S3 on Virgin Mobile so the change to the S7E is a huge upgrade. I haven't figured out yet if there are any apps (that require rooting) that are so slick I can't live without them.
I installed the U 7.0 and as I recall I got about 5 or 6 OTA updates which in encouraging. I think the AT&T ROM never received any of the 3 or 4 most current security updates. Anyhow, U 7.0 is up and running with no AT&T bloatware.

AT&T's software updater only works if you have an AT&T SIM card. This is why the first thing you should do if you buy an AT&T (or other carrier) device that you don't plan to use on that network is to convert it to the unlocked version. That, and AT&T (in particular) loads the crap out of their devices with bloatware to the point that switching to U feels like an early upgrade to the next generation device.

Yeah, I have a Cricket SIM which explains why this unlocked handset is stuck on 7.0 G935AUCU4BQA6 which is the February 1, 2017 update. Interestingly enough, the Network Signal Info app shows the SIM Operator as AT&T and Network Operator as Cricket/AT&T.
Going to the U got rid of all the bloatware and the handset immediately started receiving 5 or 6 OTA updates. I'll probably stick with the U version unless it becomes apparent there's a significantly better ROM available that increases performance, battery life or really adds some whizbangs that make the S7E experience a lot better.
forgive me for butting in -- I have a SM-G935A (stock) on Cricket as well.
Updates to the ROM and while keeping Samsung Pay are important to me.
In the past, I have d/led ATT updates and installed them using Odin, but that wipes my phone's apps/settings each time. Recently, I purchased an ATT sim & put the minimum $$$ on it with the intention of popping it in for OTA's. I've received BQK2, Nov 1 2017. It's a crappy work around, but the easiest I know of without having to rebuild my phone each Odin'ed update.
Would installing U or TMO firmware on the 935A remove the ability to use Samsung Pay? Would either of them be updated for frequently/easier than the 935A?
The U firmware supports Samsung pay and gets updates directly. The only downsides are no carrier features like wifi calling, etc., and if gets updates later than the carrier versions. I have run it on AT&T since I got the phone and it has worked fine.

This is my first phone I haven't rooted & I feel a bit powerless without Xposed and Titanium Backup. I find myself using Samsung Pay so often, that I don't want to lose it & was concerned that installing the U (or TMO) firmware on the ATT version would trip Knox, too.

Um, no. No it doesn't. Helium (or if you are feeling oldster, ADB) does a vastly better job of backing up apps than Smart Switch. Smart Switch does a reasonably good job of putting your phone's settings back, but it doesn't appear to back up most app data.
I learned this the hard way.

Samsung Pay, with the MST technology, is one of those weirdly underrated features that continually amaze people. It works nearly anywhere you can physically see the mag stripe reader, which instantly makes it vastly more useful than either Apple Pay or Android Pay. I have had more than a few people say "We don't take Apple Pay", and then drop their jaw when the transaction goes through.
The fact that Samsung doesn't make a bigger deal about it is strange, because it really is one of those technologies that sets them apart from the other two.

Worth it to root Sprint s7 Edge at this point?

Hey guys, just looking for some opinions here on whether or not people think it's worth it to root the s7 Edge right now. I just picked one up and it has MM and binary 4 on it, so I figure I need to decide if I want to root it before taking any updates. Does the official oreo seem decent? Is there any way to make touchwiz feel less touchwiz-y without root? Thanks!
I would advise to not update to any build after october 2017 if you plan on switching between carriers other than sprint as sprint is the only carrier to have updated the bootloader to 5 and many seem to believe the others won't. rooting is possible either way.
Thanks, so downgrading the bootloader is not possible once it's been updated even with root? I see on sammobile that there are several 935U firmware versions for sprint that are 7.0 but have binary 4, are these viable options? I do have a gear S3 so i would like to not lose samsung pay/S-Health, that still happens when rooted right?

Correct, once you update to any G935P firmware QJ3 or above you will be stuck unable to install any other firmware and unable to downgrade whatsoever, even with root...Trust me i'm stuck in this particular issue atm as I obtained this parts phone with the sprint motherboard that had QJ3 firmware with the bootloader 5 on it and now am unable to use it on my verizon account leaving me with having to obtain another motherboard. the 935U firmwares are completely viable options, they are just debloated and come without carrier modifications, If you need any assistance with anyting further i'd be glad to help, i don't proclaim to be a pro, but after months of research and trails on the G935P I've learned quite a bit on the do's and don'ts lol.
You are awesome, thank you! Are the roms posted in the general s7 edge section working for the sprint variant? The specific forum for the G935P is very dead. Im just weighing pros and cons of rooting, if there are good roms that improve performance and battery life available and magisk is working I think it'd be worth it to root for me

I would look more into the roms listed under verizon and at&t variants of the S7E, they are more active and most roms are made with multi-carrier support...they will say in the installation guides, but the ones listed in the general forums are mainly for the international versions if i'm not mistaken.
Also, check the forums for the S7 Flat version as they seem to be more active and most of the guides/roms apply to both variants, also confirm that in their respective guides.
I just checked for updates on my SMG930P today and it looks as if Sprint is now binary 6!? Hopefully this is a hint that the rest are moving to binary 5 for Oreo. I'm going to wait on this update just in case. G930PVPU6BRD2 is the latest update that just popped up for me.
I just wanted to verify if I flash G935UUEU4BRD1 Firmware I will still be on binary 4 which will allow me to switch carries and achieve root? Is sammobile the only reputable resource for these firmwares? Seems like they charge a bit much. Thanks guys

Anyone get official Oreo 8.0 for SM-G935U Unlocked variants?

Anyone get official Oreo 8.0 for SM-G935U Unlocked variants? I mean it seems every other carrier is pushing their Oreo already, even the Exynos model ones got Oreo, was there no love for us with USA unlocked models?
I'm waiting for the official update too. Btw have you tried flashing the G935T Oreo firmware? I've tried the G935A firmware and scrolling and overall performance feels unrefined compared to nougat.

I contacted Samsung support and they said there were issues with it, so the developers are going to fix them all before Oreo is released to the SM 935U.

Finally a update . I was beginning to wonder since the S8+s [g955u1] already had 3 unlocked firmware's with Oreo and the S9+s [g965u1] having one. Now the next is to find out what Binary version the unlocked Oreo firmware's will have since Sprints stock Oreo Firmware [g935p] has a Binary 6.
I got one this evening! Still downloading...
I updated my unbranded SM-G935U yesterday, and it has permanently disabled my WiFi! Nothing fixes it, Samsung support refer me to a service center. Tired of Samsung problems tbh. Definately getting Pixel3 when it comes out! Just gotta chug along until then without WiFi -.-

I got the update two days ago. No issues at all.
Flashed the t mobile oreo firmware on july 4th when it came out and then flashed the g935u firmware as soon as it came out. Gotta say I love oreo on this device. it makes the phone so much faster and adds so many great features! ?
Does anyone think it will receive the android 9.0 update as well?

Have you tried a full data wipe thru recovery?

Yes. When I first factory reset it, I did it from inside Android. That did not resolve the WiFi issue. My next step was to reboot into recovery and factory reset the phone that way (format data/chache). Still did not work.
I re-installed Nougat through ODIN, and my WiFi works perfectly. I set my updates to manual this time, and will not update to Oreo. I only have to get by until October, then I can get my Pixel 3.
Thank you for your suggestion.
I had a problem after I installed the oreo. Maybe just a coincidence but after about 30 mins of installing the update, I got the grey lines on the screen. Saw some people had same problems even before the oreo. I tried going back to nougat and it is still there.
