935A - upgrade to 8.1 - Samsung Galaxy S7 Edge Questions and Answers

Hi,
My main phone just bricked, and I have an S7 Edge from ATT (model 935A) on standby. However, my old phone was running 8.1 Oreo, so all my google backups require 8.1 or higher in order to restore. Alas, the highest the 935A upgrades go is 8.0, and from what I can tell they will not upgrade it to 8.1 or 9.0.
Thus, I started looking at rooting and installing 8.1 myself. Lineage or really anything that is stable and usefull. However, apparently using that 935A ATT model prevents a lot of my potential options.
Does anyone have an idea how I could do this? Seems like an option might be to flash a 935U firmware and try going from there? Or is there some different way to get my google info restored onto the 'new' phone?
Many thanks
Chris

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.

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.

Advice for new s7 Root, rom, native hotspot etc...

Sorry if these topics have been posted before but I have spent hours on here and have yet to come up with a plan on what to do. I have a new Verizon s7 still in the box. I do not want to change phones until i get it working to my needs. I MUST have native hot spot working. On top of that i would like it rooted with Xposed and all that good stuff. I would like the newest Nougat, but if i have to settle with MM, that is fine. What are my options? Stock? custom? Thanks in advance.
P.S. I have read about the 930U unlocked version. I cannot seem to find detailed info on the most up to date nougat version. Where can i find it? Is it rootable?

Need S5 Stock Rom - Sprint G900P

Hi All,
My trusty S4 lost its life and I purchased a 'new' Sprint S5 G900P off ebay. I'm having issues getting sim card to work (should work per Ting) and I've already had a few weird popup ads... so I'm going to reflash it to a known good stock rom just in case.
I'm pretty sure this is the ROM I want.
https://www.sammobile.com/firmwares/galaxy-s5/SM-G900P/SPR/download/G900PVPS3CQC1/128502/
I'm hoping to verify. And is reloading this rom just a matter of putting it to my microSD card and flashing it from the bootloader? Since I'm going for the stock rom I wasn't sure if I needed any additional tools.
Per my status page, I currently have the following. Keep in mind I haven't fully updated it just yet. I just did a factory reset and haven't reloaded anything since seeing the popups. So this is how it came.
Software Version
G900PVPS3CQD1
Hardware Version
G900P.04
Model Number
SM-G900P
Android Version
6.0.1

Stable Root for SM-G935P?

HI. I have a question regarding my s7 edge on sprint (SM-G935P) and to whether or not anyone has found a stable rooting method for it. Im somewhat experienced in this kind of topic as i have rooted my phone multiple times and have found success but all methods resulted in a very laggy phone. So im not new to this but could use a little more knowledge. From what i know, the root methods used to root the snapdragon models of the s7 and s7 edge are using ENG Boot and in result, that's why devices are not as stable as they are on stock firmware. Because of locked bootloaders and from my understanding, there is no way to root without a laggy phone. Unless you were to unlock your phone, there's no way of rooting without lag? Also, from what i gathered up is that you can convert a SM-G935P model phone to a SM-G935U. G935U is the unlocked firmware? If so, if i try to root will i keep the sprint service? I may sound silly right now but im posting this to better understand if any one of you have found a rooting method which eliminates all lag or as much lag as possible. If there's is nothing i will probably be better off sticking to my stock s7 edge like i have been for awhile now. I have found this though and im curious to know if this has anything to do with my post?

It depends on what version you are using at this time. That U root only works if your sprint phone has a binary version of 4, sprint updated the binary in December. That makes all sprint S7E phones that received that December update unable to root as they were updated to binary 5. To find out what what binary version you have, go to setting and about phone. Look for the updated version (it should start with G935P), The 5th to the last number will have either a 4 or 5 on it. If it has a 4, you can root it, if it has a 5, you cannot root it. The U root will work on all American phones as it is programed for GSM and CDMA phones. You may lose all those "awesome" sprint apps when you use the U root flash.
I am very curious on this issue also. I just moved from Colorado to Wyoming and Sprint does not offer unlimited data roaming, so I want to unlock and maybe transfer services to another company, AT&T and Verizon are the two that seem to provide direct service here. But the rooting issue would be a possible huge advantage, maybe....

Hi there any to root this phone with magisk?
mikeb143777 said:
Ok, ive scoured the internet and got conflicting results. However, Im not a pro, and it appears you have the low down on the current root status. So here is my question for anybody that can help. I have the Sprint S7 edge (SM-G935P), and Im pretty sure Im on the number 5 bianary, so it appears that Im stuck. But please clarify, does this mean that there is no way to root my phone period? What if I dont go to the "U" firmware? Or better yet, isnt it possible to rollback to a different firmware, to marshmallow or something, and then go from there? I heard you can roll back if you have a "pit" file or something? Can anybody offer me any way to get rooted? Im sure I can follow the instructions if I can find any, Ive rooted plenty, but so far I havent found any options. Thanks.

Sorry I didn't get back sooner, I don't go to the sprint part of the forums as much anymore.
At the time, the U Firmware was the only way you could get root. The root method has changed but it still requires the same or lower binary version than the rooted rom. If you are binary 5 and the other ones are 4 you will not be able to root. From what I've seen so far, verizon and the U firmware is still binary 4. What makes this worse, is once you are on a higher binary version, you can no longer downgrade (I've tried during bricking). I have tried a pit file with a non sprint phone and could not get the phone to downgrade either.
Right now you can either wait and see if they upgrade to binary 5 and root then, or you can get an unlocked verizon s7 edge and get root. Both are not the greatest of options
It gets worse... Getting root on a newer phone is not like the older days. I am rooted and all I can use is an altered stock rom. Because the bootloader is locked you cannot use custom recovery and roms like lineage and crDroid. So even if you get root, depending on what you want to do, you will still be limited.

A2017G Japan - Lots of Questions...

Okay, so I used to love rooting my phones, but I mostly dealt with flagship phones in the US which made rooting and flashing a cakewalk. I understand some of the nitty gritty, so when I got my first phone in Japan, I was super excited about rooting it. But after reading this forum for hours, I have so many questions...my phone build is A2017G JPV1.1.0B03.
I read this but this mostly focused on using an update on this phone.
https://forum.xda-developers.com/axon-7/help/a2017g-japan-to-a2017g-european-a2017g-t3608411
1. If that thread is correct, that means I technically just have the European version of the phone with Japanese modems installed. Is that correct?
2. Also, does that mean (if I were not to root the phone) I would need to install a European Axon 7 Oreo update for it to actually work on the phone? Would the US version fail?
3. I can't seem to find the modem for my phone. I can upload some screenshots later but can someone clarify if I'm right that it's a "B03" or am I looking at the wrong information?
4. There is no Oreo release for Japan, so does that mean I can't flash an Oreo ROM because there won't be any modems for this?
That's all for now, but I'm sure I have a lot of follow-up questions to your answers. Your help is greatly appreciated.
Unlock bootloader, install twrp, instal "G" model bootstack, instal any custom rom, then flash "G" modem in twrp, reboot. No matter where you device are from, the model matters. If its "G", its a european version and its only what you need to know. If you want stock oreo and didnt recieve through OTA, download the update in ZTE website for your "G" version, put it in a sdcard then reboot your phone to recovey then select "install update from sd card" option.
Basically, the model of the phone is printed on the back of it down the bottom.
A2017 is China version.
A2017U is US version.
A2017G is everything else (Global) version. It's not actually euro.
The modem software has to be for the actual model of the phone, not your location in the world.
Don't correlate software versions between Chinese, US and Global, they use different numbering systems. Only concentrate on what is for your model.
The rest of this pertains to A2017G as that is what you seem to have.
They start at B01 (usually pre-release beta) and go up from there but each new Android version eg Nougat, Oreo etc means the numbers restart from B01.
Nougat B03 has nothing to do with Oreo B03.
Look at the software version, A2017GV1.1.0 is very old, the 1.1.0 is the key to the Android version. 1.2.0 is Nougat, 1.3.0 is Oreo so you have Marshmallow at 1.1.0 and B03 release from that Android generation.
It seems confusing at first but it's actually quite simple.

I'm so used to dealing with multiple modems for the same model of phone in the US (between the major carriers and stuff) that I was overthinking it.
Thanks a ton. That simplifies things so much...and also makes me wonder why updating never occurred for the Japanese release. It's not like there isn't language support for newer versions of Android, but maybe not for the MIUI? I need to be more careful choosing my next phone then, though probably it should be an AOSP phone like the Zenfone or Pixel.
Guess I have my work cut out for me this weekend. Time to run a giant backup and start rooting. Thanks again for all your help. I like this phone (though I often accidentally hover/touch the home button when typing, and I hope there's a sensitivity fix for that :laugh so I want it to last for a while before I get my next one.
It's still a good phone, I look at new phones and think, hmmm, nice, but what will I gain on a daily basis? Nothing more to be honest. The A7 has enough power for me still. The one thing I could really use would be a higher capacity battery. Was looking at Huawei phones but now, well.....
For updates, they had issues with OTA and reverted to only releasing for a whole ROM download for update from SD card.
I personally won't apply an OTA for mine even now at Oreo. Must be a whole ROM to flash with the updater. That's all I've done with it since purchase and it works great still. A lot of people seem to have all sorts of weird issues after applying OTA updates.
Sweet. As someone with some experience with this stuff, do you have any tips or tricks I should know moving forward? I'm going to try rooting it tonight.
-EDIT: Quick little question, my phone says the Android version is 7.1.1 but that would be Nougat, right? Or is it actually Marshmellow?
7.1.1 yeah, Nougat. That doesn't make sense from your first post.
Was it used when you got it or new? Have you checked the model from what's on the back of it, not what software says it is?
I keep mine stock, can't advise on rooting etc. I use it with personal and work SIMs and it has to pass requirements including encryption to run Microsoft InTune and our company portal and use it in work mode. Bootloader hasn't even been unlocked. The most I did was uninstall some built in user apps through ADB.
I also have a 2017G bought in Japan. I unlocked it and worked on it based on this forum, and I can say that it behaves as any other 2017G. I am not interested to use the stock ROM, but yes, I remember that it was on Nougat version when I received it.
I have the A2017 (china). As above, update your phone to the region. As a result of having a china variant, i think i miss out on band 28 and some other essential bands for reception. I get 3G/low 4G connections and a lot of bad reception areas (countryside living). Its no problem.
Currently running AEX 6.5. Search some of my recent posts for how I updated to this version.

Appreciate it. I will try to work on it this weekend, as last weekend I just didn't have the time...
The phone was brand new when i bought it. It was on a "super sale" though, going for 12,000 yen (like 110 bucks or so). I was thinking about getting a Zenfone but if I could save the money and make it to at least Oreo I'd be happy. Been having issues with the battery whenever I use more than 2 apps at a time.
If you could link an unlocking guide and a ROM that worked well for you that would be great. I have one I plan to use but I'm always open to suggestions. After the first time, I'll feel more comfortable with it. In the worst case scenario that I brick this thing I'll just buy the Zenfone early :laugh:
The Zenphone 6 is looking a viable buy now.
My Axon 7 is still good so not really looking but I did just get a new Axon 7 Mini for use as a media player. It still has AMOLED screen, stereo speakers, headphone jack, DAC for the jack etc. No hi res bluetooth though. Cost me AU$149 new in box from retail store. Bargain! How much is a dedicated music player which is crap at movies or just cant do them?
Chucked my 128Gb SD in. Sounds good playing through the car hifi, lower 3.5 jack output matches HU aux in impedance better than Axon 7 which can overload the input at high volume. Very balanced and clean sound.

Where did you get in on a super sale? website in Japan?
Obvious unlocking guide is this one https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-custom-oreo-roms-newbies-t3786693
Give yourself 2 hours to get the job done, and there are a few guides on youtube for unlocking the bootloader and installing TWRP (if you havent already).
If you cannot root the phone by your own discovery, I dont think you'll be up for installing a custom rom. It takes a degree of risk, and research. Being successful in the attempt is worth it.
Do a backup in TWRP, or get titanium backup pro (paid) to do a backup of your essential apps and data (email, messaging, google authenticator etc). I think titanium backup is better, especially if you are going from android 7 to 8 or 9 and different twrp versions.
If your phone boots following Oki's guide (Option 1), then scroll to the last page to my post about taking it to android 9 on AEX.
As your phone is A2017G, search for the necessary files in the forum corresponding to your modem. There are plenty of links.
Good luck and let us know you are successul!

Where did you get in on a super sale? website in Japan?
Obvious unlocking guide is this one https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-custom-oreo-roms-newbies-t3786693
Give yourself 2 hours to get the job done, and there are a few guides on youtube for unlocking the bootloader and installing TWRP (if you havent already).
If you cannot root the phone by your own discovery, I dont think you'll be up for installing a custom rom. It takes a degree of risk, and research. Being successful in the attempt is worth it.
Do a backup in TWRP, or get titanium backup pro (paid) to do a backup of your essential apps and data (email, messaging, google authenticator etc). I think titanium backup is better, especially if you are going from android 7 to 8 or 9 and different twrp versions.

I bought it at Rakuten Mobile. There was a super sale and it was like 80% off, lol.
I tried using the guide over the last couple of days and no matter what I've done, I can't seem to get to recovery after doing the flashing (step 9). I was able to flash a stock image back on, but then when I try again it's the same results. I'm at a loss as to why but...there's another guide using the Axon7Tool.

The downside is that I work two jobs tomorrow so I won't have time to try this new one out but I think I downloaded everything already. This is kinda frustrating though..
-EDIT: I used the unbricking guide to EDL flash the B10 Nougat and it is a different experience than what I had before...geez, seems the Japanese version was severely neglected. If I run into problems with the other guide I feel comfortable EDL flashing Oreo. Really appreciate the support guys, let me know what you think. Before I started this, my battery was lasting barely 8 hours with only LINE and Chrome being the main background apps...
Not sure it's relevant here any more but I have a 128 Gb A2017 which I put a G build on, after being a bit miffed at some of the stuff (mostly Google based) I couldn't use on the original. I really don't know that much about what I'm doing but it all seems to work OK, though an old battery life problem has returned so I'm going to be asking elsewhere (probably) about how to replace the modem software. I also have a bit of a problem with GPS intermittently not working (going on and offline) but I suspect that's probably a hardware problem rather than the build. Mine is on

you can't. There are 3 modem variants by region (US, china, global) and many versions for each, but they are not interchangeable and flashing another has already wiped some IMEIs long ago (doesn't always happen though)
