Hello all. I am new to the world of android and would like some assistance with a topic - flashing stock firmware.
I bought an AT&T S6 Edge+ outright and absolutely love the phone. Except that it's filled with all sorts of AT&T apps and certain functionalities of the phone is disabled. I researched the topic of flashing the firmware to another region/carrier's stock firmware and it seems that this is a possible route to "debranding" the phone. However I also learned that AT&T locks the boot loader. Will this have any impact on me flashing the ROM with another firmware for this model?
Thanks for all the advice and patience!:good:

Anyone who can help? Same issue here, can't stand this **** by at&t
Not possible
Device specific firmware is on carrier devices so if you try to put kor or T-Mobile or whatever on one the american s6 or edge then I believe its the bricks for you...I also believe if you have a clean imei the carrier will unlock it for you don't hurt to try ..the story is you may have to be on their network activated and also if you purchased through the payment option after its paid off it can be unlocked ..debranded whatever

Do what I done, Sell the phone on Swappa, Ebay, Amazon or Craigslist & purchase
an international version of the S6 Edge+ or any other Samsung International phone.
They all come factory unlocked and very easy to root.
The only feature the T-Mobile users will no longer have
is the wifi calling. Being rooted is an excellent trade-off
for the wifi calling feature unless you live in the middle
of no-where. LOL
All the other features work just as good in all the
international phones as with the branded phones.
Good luck and have a great evening!
If anyone wants to root their US cellular S6 Smg920r4 on 6.0.1, I know there's no section here for US Cellular, but this works perfect. It's the Sprint TWRP 6.0.1 Marshmallow root method. Just follow the instructions in the Sprint thread. Root in minutes thru Odin. Hope it helps someone else like me who was looking and looking for Sm-g920r4 specific root.

I've got xposed running with a few modules that are stable and somewhat supported on marshmallow. Again it's super easy to root your stock firmware on your US Cellular SM-G920R4 Galaxy S6. If anyone has any questions, please let me know. Thanks
Twrp
My s6 won't boot into system it boots into twrp recovery. And I did make a backup of my phone with Smart Switch and now Smart Switch tells my device is not supported. Any solutions?
What firmware were you on? Were you already on 6.0.1 and did you get it fixed yet
How did you get Xposed to work? Did you have to use a custom rom? If so what one did you use?
thank
Thank to me
I'm still hesitant to pull the trigger on this. I see questions being asked about things that I don't fully feel comfortable stressing about. Was this a successful way to root or a fluke that may work for some?
how to install edge screen on s6, just like s6 edge

For sure. US Cellular is small beans compared to the other major companies so its always been hard to find it. This is the first device I have ever struggled to find a way to do it though. All other took work, but this one is the only one so far that has been impossible.
I was able to get his ROM loaded onto my phone but there was a spot where I had to "select CSC" and US Cellular wasn't listed as one of them. I think T-Mobile and Rogers were the only USA companies that it had. Maybe I should have tried it by selecting T-Mobile or Rogers but I just didn't really know what to do. The one that I tried (which was a UK CSC - because it mentioned something about selecting it if yours wasn't listed..but I believe it was only talking about UK companies not listed) wound up getting the ROM to load but I had NO touch screen capabilities.
After 6 hours of getting that that point and having to reload the official Samsung ROM, I gave up and went to bed.
I wish I could find someone that has been through this already to lean on for some assistance but with this phone, it seems like no one has been first. Maybe that is my purpose in life.. But then again, I also don't want to completely brick my phone in the process. Maybe I'll try again tonight.
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.
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
Im only posting this here because im a new and it won't let me post to the s7 edge forums. I'm not a pro like many people on this site but I'm feeling like a real idiot right now. I recently got a sprint s7 edge (sm-g930p) and I was trying to flash it to 935u because I use Mint mobile and it runs on the tmobile network. I downloaded the files from another users post about doing it, plugged them into Odin, tried to flash it, but it almost instantly said fail and now my phone just keeps restarting. As far as I am aware, the s7 has current updates and I just don't know what to do. I could care less at this point if I flashed it back to the original sprint version but I'm not sure what is possible by this point and I'm hoping someone here can help me.
Thanks.
