Trying to root AT&T Galaxy S7 on Oreo - AT&T Samsung Galaxy S7 Questions & Answers

Hello,
I'm new to this whole root business, and I wanted to try it out on my wife's old Galaxy S7. I followed a guide on tenorshare.com.
When I tried to root the phone, I got an error that said "Odin version protocol error." So then I downloaded a different version of odin and then I made it past the first error, but then got one that said "Fail! SHA256 is Invalid". I've been looking around and can't find any clear answer. The phone is a Galaxy S7 on AT&T, running Oreo. It is model number G-930A.
Just wondering if anyone can help. I'd really like to try out a rooted phone, but it's proving harder to achieve than I thought. Thanks in advance!

Well if you have a regular S7, you're on the wrong forum. This one is for the S7 Edge AT&T models.
Here's where you need to be posting at for your phone.

Sir, it means that your baseband doesn't have that kind of firmware.

S4 UPDATE , FLASHING AND UNLOCKING ISSUES- read me.

Hi, good day and thank you for reading.
I'm stressed out. I need any help I can get, what's happening is that I bought two phones in attempt to refurbish it and it came with errors. Whenever I try to update it I get " Status 7 ; installation aborted ) along with many other stuff. Additionally, the device I bought was supposed to be unlocked but guess what. It isn't . ( also not sure if rooted but i assume its not )Please help in anyway possible.
I'm not a phone tech but I know my way around. It's two devices, both from sprint.
Device 1: SPRINT sph l720 )- this is unlocked. Only need to probably flash my device and put lollipop on it. It's currently 4.4.2 kit kat but when I download and go through with the update, status 7 installation aborted. This brings me to my next issue. My baseband number is different from the lollipop rom that I'm finding online. Should this be an issu? baseband number- L720VPUAMDC.(will flashing make the phone locked to sprint again?)
Device 2: SPRINT sph l720T.(Baseband : l720TVPUBOA3)- This is locked and won't update. Same error as mentioned above. (Sprint spark)
It would be nice if someone could carry me through the steps I'd need to fix this (flashing to lollipop and unlock or any other method to be honest. I'd just like to overcome this issue as soon as possible to sell these devices)
And thank you thank you thank you in advance for the assistance. I really needed it.
The International S4 forums is the wrong place to ask this. http://forum.xda-developers.com/galaxy-s4-sprint is where you need to go, as there will be more people familiar with the device.

Some help please

Hi,
So i tried to update my galaxy s6 edge to the latest firmware and once it did, it got stuck in the samsung screen and wont boot. The phone was rooted before, and now it just stays stuck. I have restarted the phone and now I have tried flashing the phone using Odin. It keeps saying failed and it shows the following:: " SW REV. CHECK FAIL. DEVICE: 2, BINARY: 1"
I dont know what to do to be honest, if anyone can help me i would really appreciate it.
Might I suggest the S6 Edge boards? You're more likely to get the right answer there. You'll find those over here.
Still, this is a pretty general Samsung error.... Not my area of expertise, but a quick Google search on "SW REV. CHECK FAIL. DEVICE: 2, BINARY: 1" reveals this error occurs when you A, try to downgrade the bootloader, or B, flashed the wrong firmware.
Suggested solutions include booting in Download mode and flashing the correct firmware, or if that fails to flash the correct firmware with the PIT file.
Which firmware did you use?

Okay, that's officially weird. I've seen softbricks happen after OTAs quite a few times, but never with this error.
You should be able to find the correct firmware here: http://www.sammobile.com/firmwares/database/SM-G925T/
As for the PIT file, there's no database of those. Someone on the T-Mobile S6 Edge boards probably has one. You'll need to ask on these boards, the link in my previous comment is for the international S6 Edge.

No AT&T or T-Mobile Service with SM-G900FD After Marshmallow Update

I recently purchased a used SM-G900FD that worked with both TMobile and AT&T when I looked at it. I checked the IMEIs but then things got weird.
I wondered why it was still on Kit Kat and wasn't updating OTA, so after some reading I downloaded Phone Info. I noticed two things, S/N was 00000000000 and it was rooted. So I downloaded Odin, and I think I downloaded the correct firmware.
I am now in 6.0.1 but the phone info now says it is not rooted and I can't get service from AT&T or T-Mobile. Do I need to be rooted to get service?
What did I do wrong? I hadn't used it because I was waiting on a case and wireless charger, but I broke my zenphone 2 screen today and need to start using the S5 ASAP.
I am new to rooting, so any help is greatly appreciated.
A few other things I should mention.
Phone Info "Country of Origin" is blank.
And the firmware's CSC code is CAC.
Firmware is currently G900FDXXS1CGP1
Again, new to this so any help is appreciated.
Thanks.

S7 Edge G935P issues Flashing Supposedly compatible G935U Rom

Hello Everyone I understand that this would have been better posted at the Roms and development Forum but it would not let me post because of some anti-spam thing. Anyways I was told that I could Cross flash the g935U rom on any variant of the S7 edge so I tried to install it the same way I installed the Stock Sprint G935P firmware. When I was flashing the flash stopped and locked up. The phone has a error on the screen saying SW REV CHECK FAIL : [aboot]Fused 5 > Binary 2. Any help would be appreciated. Attached is a picture of the screen and the Odin Logs.

Ran into the same problem. It seems Sprint decided to switch to binary 5 on the QL1 firmware while the rest of the carriers didn't and stayed on 4. I have been looking all over for a way to root my SM-G935P on QL1 firmware and have found nothing. Looks like we're SOL for now thanks to Sprint.
So We Need To Wait For The Android Oreo Update or just wait for G930U To Update The Firmware

You rooted SM-G935P on G935PVPU5BQL1 firmware? If so ...... Yes please show me the way. Been trying to figure it out for quite sometime.
can you downgrade to the previous versions of marshmallow and them rom over to 935u?
you will have to find the previous boot loader file and flash all 4 together for it to work.
just a guess. ill do some research.

Was going to do the same thing after getting a good deal on a pre-owned s7edge from BoostMobile. I had no problem getting the sim unlocked for MintSim(MVNO-Tmobile), and it seemingly works fine after setting APN settings. I'd prefer to not have the g935p firmware. I'm assuming if I can somehow switch to g935u I'll be able to use it more comfortably for both verizon pre pay and MintSim? If there is a way to downgrade to the binary 4, I'd like to know as well. As far as I know I'm still able to use Samsung Pay, so I'd like to keep that option open.
Only thing we can hope for as of right now is that the oreo update is binary 5 on the U firmware. But I dont see that happening. Think thats a new exclusive for sprint to keep people tied down. Hopefully im wrong....
On a more positive note, the bootloader binary has been updated across carriers with every major os upgrade.

I think the same. Sellers were selling S7 and S7 Edge models with U firmware for international use, no sprint apps, logo or restrictions and maybe sprint was losing customers and they decided to update the binary to avoid this situation. Really I prefer the U firmware instead Sprint or Verizon stock rom

On the Oreo update? I havent even checked.
Hasn't been released yet, but it has happened from MM to Nougat. Just speculating that it will happen when Oreo drops.

Updating my G935A

Hello folks,
recently my uncle bought a Galaxy S7 Edge G935A via ebay. Since we live in Germany I was sure to get a G935F firmware on it. Well it seems that I'm wrong.
First I downloaded G935F 8.0 and tried to flash with Odin but it failed with 256SHA failure. Afterwards I found out about the Prince Comsy Odin to "bypass" this error. Well, luckly, I haven't updated it.
After reading further this might be a At&T device and that At&T branded phones are only updated via at&t itself so to try out with the bypass might have bricked the phone. (the distributor seems to be placed in China but he is not answering anything anymore) ,
Then I found this one Teamdroid Oreo for G935A and read the article thoroughly. The pictures clearly show a baseband of XXX UCU4CRE4 while mine shows G935AUCS4BQC2.
Right now Im on security patch from march 1st 2017. The device itself and smart switch says it is up to date.
So my question now. What to do? Can I just flash the G935F onto the device with the Prince Comsy Odin, or can I flash the UCU4CRE4, or am I just unlucky and we have to take the bite and leave the device as it is?
Thanks in advance
//E: out of curiousity: Why is there no such device as G935A listed @ sammobile site?
//E2: so I tried to flash the UCU4CRE4 with "normal" odin and I'm receiving the error emmc_appsboot.mbn.lz4 failed and on device it says unsupported dev_type ---> issue fixed with newest Odin (13.1) --> flashed it successfully...maybe it helps somebody
The G935A is a snapdragon variant, therefore G935F firmware would never work because the G935F is the exynos variant. They have different hardware and are fundamentally different.
It looks like you were able to get upgraded to Oreo (CRE4), that's great! you should be set as long as everything is working right. You won't ever get OTA updates though, AT&T devices must have an AT&T SIM card installed in order to recieve them. If I was you I'd just check back here on XDA for updates every few months.
If you don't want the AT&T firmware at all, you could flash the G935U firmware instead, which is the unlocked firmware for the USA Snapdragon variant. It's easy if you use the princecomsy Odin. Not sure if the unlocked variant has Oreo yet, though, so you may be better off just sticking with what you've got.
