Root Android 7.0 Nougat on Galaxy S7 & S7 Edge devices. YES! Supports all USA Qualcomm variants. T-mobile, AT&T, Verizon and *Sprint (*Note: Some people have reported problems with the Sprint device after root, while others have had success. As always, read the thread for detail and use at your own risk)
** THIS IS NOT FOR THE EXYNOS VERSION OF THE S7! **

A few answers to common questions:
YES - this breaks Samsung Pay and probably Android Pay (you will NOT be able to use Samsung Pay after root)
YES - this process is reversible by several methods, one of which would be simply doing a factory reset and re-flashing the complete Nougat Android 7.0 Firmware files in Odin, More details on this below.
NO - this process does NOT trip the KNOX counter
NO - there is no TWRP or custom recovery for this method of rooting
NO - there is no XPOSED framwork for Android 7.0 currently (as of today's date)
YES - There is a Android 7.0 custom rom! Thanks to @jrkruse https://forum.xda-developers.com/tmobile-s7-edge/development/rom-t3572739



Many thanks to the people who released the files! I am only posting the file's in a single easy to find post along with my experience and instructions which may or may not work for you! these instructions may or may not be right. these instruction may or may not be missing crucial steps. USE AND PROCEED AT YOUR OWN RISK! No one is responsible if you damage your device. CERTAINLY NOT ME!

@jrkruse for his awesome job for making a custom flashable Android 7.0 Nougat ROM https://forum.xda-developers.com/tmobile-s7-edge/development/rom-t3572739
@Chainfire for creating SuperSU and other great android utilities.
I'm sure there are many others, but I don't know who all created what, so I'm only listing those who I know - if I messed this up, I'm sorry in advance.

ENG (AP) files for S7 and S7E (from this post https://forum.xda-developers.com/showpost.php?p=71271898&postcount=28 )
https://www.androidfilehost.com/?fid=457095661767141717

*edit: newer method available!*
SuperSU 2.79 root.bat file (from this post https://forum.xda-developers.com/showpost.php?p=71281527&postcount=50 )

(This is the command prompt script you'll execute from a CMD prompt from a windows PC that installs the needed files for root access like SuperSU)

**EDIT: @jrkruse on 5/29/17 has created a new ROOT.BAT including SuperSU v2.82, it has been outlined in this post #480 of his custom rom thread. As always, please take a moment to hit the thanks button! Without the work of these amazing dev's we would NOT have root PERIOD! It is free for you, and mean's a lot to everyone involved in bringing these releases to you the public!!!

Here is latest root zip with SuperSU 2.82 (5/29/2017)

Sorry about all the VOLTE Icon problems
If your having FC issues your going to have to copy the original imsservice folder with imsservice.apk and oat folder to system/priv-app before you can flash this fix

This new zip should fix fc problems as no apk is replaced no more just the icons are replaced inside the apk

Volte Icon Fix Is now one zip for all S7 Variants. No more flashing wrong zip and getting FC. The zip only replaces Icons in imsservice apk. This zip will work on odex or deodex roms
S7_VOLTE_ICON_FIX_ALL_VARIANTS.zip

YOU MUST MOUNT SYSTEM IN FLASHFIRE WHEN FLASHING!!!

ALTERNATIVE SOLUTION from Post #413: Thanks to @sabresfan post #413

You will need to download and use only the PrinceComsy modified Odin which I got from https://www.androidfilehost.com/?fid=24591023225177749

Kernel Adiutor can be downloaded from Play Store
https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor

Original stock firmware files can be found on these sites or searching XDA
https://www.sammobile.com/firmwares/
http://updato.com/
** Edit: More information about returning to STOCK below on this first post **

**EDIT: Samsung USB driver's direct from Samsung web site http://org.downloadcenter.samsung.c...G_USB_Driver_for_Mobile_Phones_v1.5.45.00.exe

I'm not sure if you need the ADB files installed system wide or not? But you can also download and install the 15 minute ADB drivers. (use google or search XDA)

AGAIN: I did this to my Samsung Galaxy S7 Edge on T-mobile G935T RUNNING ANDROID 7.0 NOUGAT I believe this will work with other USA released carrier variants using Qualcomm chipset (T-mobile, AT&T, Verizon and Sprint)... BUT YOU DO THIS AT YOUR OWN RISK.

EDIT: MAKE SURE YOU ARE ON ANDROID 7.0 NOUGAT - OBVIOUSLY. (Baseband Version: G935TUVU4BQB1 in the case of a G935T S7 Edge) :fingers-crossed:
This process did NOT cause any data or application loss for me. I did this procedure from an OTA upgrade to N from MM.

Obviously, Download all needed files in advance and unzip accordingly.
Put your phone in download mode (Volume Down, Home and Power) then click home again to continue to download mode
Launch the modified ODIN on your PC
Unzip ENG BOOT file and get the boot.tar for your device (in my case it was the S7edge_qualcomm.tar was the file I needed for the S7 Edge) DO NOT UNZIP THE TAR FILE.
Put that .tar file in AP section of ODIN
Connect your phone, you should see a lighted COM port selected in ODIN meaning your good to go.
CLICK START in Odin. You Phone will flash the file quickly and restart.
Let it boot up fully and wait until you can unlock the phone (go to desktop of the phone)
Now open a CMD prompt on the computer and navigate to where you downloaded and unzipped the SuperSU 2.79 earlier
in the CMD prompt type root.bat this will push the required files to the phone and it will be rooted when its completed.
After a few minutes your phone will restart, and you will have SuperSU and root access on Android 7.0 Nougat.

This is how I rooted my SM-G935T Samsung Galaxy S7 Edge on Android 7.0 Nougat. Yes this is a bootloader locked T-mobile branded device.

Please feel free to add or correct anything here in the posts below!

EDIT: You'll want to install Kernel Auditor from the Play store, grant it supersu permission, and set both cpu govenors to ONDEMAND and set apply on boot. (core 1&2 default to performance and core 3&4 default to interactive - set both to ondemand and apply on boot)
EDIT2: You may want to experiment with the CPU governors in Kernel Adiutor (that's actually the correct spelling according to the author). It's been suggested CONSERVATIVE will give you better battery life than ONDEMAND. So you'll want to try the available options and see which results in acceptable balance of performance and battery life for you.

GOOD LUCK! AND THANK YOU!
I HOPE THIS HELPS PEOPLE GET ROOT ON THEIR USA QUALCOMM DEVICES
PLEASE TAKE A MOMENT TO THANK THE PEOPLE WHO BROUGHT THIS INFORMATION TO YOU.

Returning to STOCK Android 7.0 Nougat

You will need to have Odin installed (same modified Odin linked above should work fine)
You can download stock Android 7.0 Nougat firmware from

When you extract the .zip file for your device, you have 2 options for the CSC section. One file will erase all existing data and apps, reverting your phone to a like new state. The other will preserve your currently installed apps and data.

CSC_TMB_G935TTMB4BQB1_CL10376601_QB12449118_REV02_user_low_ship_MULTI_CERT.tar USING THIS FILE WILL ERASE ALL EXISTING DATA ON THE DEVICE
HOME_CSC_TMB_G935TTMB4BQB1_CL10376601_QB12449118_REV02_user_low_ship_MULTI_CERT.tar USING THIS FILE WILL PRESERVE (*NOT ERASE) ANY EXISTING DATA FROM THE DEVICE

Obviously you can only choose 1 of the CSC files. Using the HOME_CSC keeps your existing data, and the other CSC formats your phone.

Thanks to @billa (https://forum.xda-developers.com/member.php?u=293193) for taking taking the time to put these tips together for everyone.
Slightly edited by me ;)

Note (and suggestions)
----
Before and after rooting wipe the cache.
For tweak settings to stick, must reboot multiple times.


Security Updates OFF
--------------------
Settings > Lock Screen > Security > Other Security > Security Policy Updates > OFF and Wi-Fi only


Disable (things to disable after root - Use Titanium Backup or Package Disabler Pro for Samsung, both available from the Play Store - Worth the price to buy!)
-------
Samsung DM Phone Interface
Samsung DM Service
SecurityLogAgent
com.sec.android.soagent
com.wssyncmldm
tethering.automation
tethering.provisions


After Eng-Boot (root is complete)
--------------
Install Kernel Auditor, and set both CPU govenors to "OnDemand" and set apply on boot.
Set cores 1&2/3&4 to "OnDemand" and apply on boot.
EDIT: Experiment with governor settings until a balance of power and performance is reached. Kernel Adiutor is available from the Play Store


Performance tweaks
------------------
GovTuner - set to interactive and performance
Kernel Auditor
Kernel Toolkit
LSpeeds
SSD Boost


SHealth fix
-----------
Set ro.config.tima to 0 in build.prop


WiFi passwords fix
------------------
Set ro.securestorage.support to false in build.prop


VOLTE/RCS icons OFF
-------------------
Copy the imsservice.apk from the root zip to
/system/priv-app/imsservice/
and set permissions to -rw-r--r--


Data toggle
-----------
Use SQLite editor and add MobileData to a string in settings.db



Busybox fix
-----------
Install busybox to /system/xbin instead of /su/xbin


Sprint LTE fix
--------------
In Build.Prop change the following:
ro.cdma.default_numeric=310000 to 310120
ro.cdma.default_alpha=Chameleon to Sprint
ro.build.characteristics=Chameleon to Sprint

OR

Go into settings
Click Connections
Click Wi-Fi Calling
Click Cellular Network Preferred
Go back two times and click on Mobile networks
Select Network mode and select 3G/2G (auto connect)
Restart your phone and call 611 just to make sure the call goes through
Hangup and go back to Network mode and switch back to LTE mode

As always THANKS to all the users who continue to contribute to this thread, and to all the people involved in bringing you this information so you can ROOT your Samsung Galaxy S7 or Samsung Galaxy S7 Edge on Android 7.0 Nougat!

I will continue to update this first page with relevant links, details and information in an attempt to keep the information easier to find for everyone.

Take a moment to press the THANKS button!

As stated in the OP, what you do at this point is at your own risk. I did it, and worked smoothly. Not sure if you need CMD drivers installed before hand, probably do, but I clicked on the Root.bat, and it did it's thing. So far, so good. Thanks to the above contributors without a doubt. Snappy so far.

So how's the lag for you compared to the eng boot on marshmallow?

I never did the ENG root on MM, so I can't compare. The lag right now is absolutely there. I'm trying to tweak and reboot as I go. Trying to get it better.

I installed Kernel Auditor and set both of the CPU gov's to ONDEMAND - but it won't stick on reboot, one defaults back to performance and the other (core 3&4) defaults to interactive.

I think the SuperSU root file has the needed ADB files, so once you navigate to that folder in CMD (command prompt on the pc for those a little lost), I assume those files are whats used to push the root.bat script to the phone? I think we are both right? but I'm not 100% that's why I mention the ADB drivers, which were already installed on this PC I used. This information was scattered in several threads, I was hoping to put all the links in 1 place so we can maybe get this working smoothly for EVERYBODY.:good:

Since you did it too, and you're getting smooth results what steps did I miss? if any.:fingers-crossed:

I did exactly as you said and worked nicely. The only thing I would add is to already be on Nougat but that might be obvious. I didn't do that earlier, and ended up in a boot loop. Thanks for putting it together. Tomorrow I'll post any lag issues.

I just installed it, seems to be running pretty good. Definitely a lot smoother than the MM eng root. I mainly installed because I wanted to get Google assistant lol.

To enable Google assistant you have to use a root explorer app or ADB and change + add a line to the system/build.prop

Change first line to

ro.product.model=Pixel XL


Copy and paste this into system/build.prop

ro.opa.eligible_device=true

Reboot and you have Google assistant!

to make it stick on reboot i think there should be a setting there that says apply on boot

Give this a try and see if it gets rid of that stupid icon
TMO_VOLTE_ICON_FIX.zip
Hey thanks for coming over here...

As I mentioned, I don't care about the big hurricane looking icon, but the com.sec.vmimservice icon notification (looks like a red face) pops up multiple times in my status bar whenever there is texting activity. Send or receive. That's what I want to get rid of.

Edit: here's the notification pulled down so you can see.. I have that little red icon in my status bar several times right now... I am using Android messages, and I use Tmobile digits on my other phone (note 4) just fyi... Not sure if everybody is seeing that or if it's unique to either Android messages (formerly Google messenger) or digits service by Tmobile?

Somewhere between reboots (of which there have been many tonight) the setting finally stuck. I also set kernel auditor (adiutor) to set the settings immediately on reboot with no delays.

To me, there is still significant lagging, even with on demand Governor set. I read somewhere about setting the min/max also, those values are always fluctuating in the kernel adiutor program, I'm not sure how to properly set those.... But I also tried kernel tool and had similar results. Just fyi.

Have you tried flashing the fixes from the popular root thread? Or is it not needed?
Honestly I don't think most of those fixes are still relevant even for MM 6.0.1, so I doubt any flash able version mod would be suitable for N 7.0 [emoji6]

So far, what I've done is wiping cache in recovery (volume up, home and power)
Set the governors to on demand... Beyond that we will need some experts to chime in with suggestions, tips and advice.

If you set govenors to conservative you will get way better battery life.

    EDIT: MAKE SURE YOU ARE ON ANDROID 7.0 NOUGAT - OBVIOUSLY. (Baseband Version: G935TUVU4BQB1 in the case of a G935T S7 Edge) :fingers-crossed:
    This process did NOT cause any data or application loss for me. I did this procedure from an OTA upgrade to N from MM.

    Obviously, Download all needed files in advance and unzip accordingly.
    Put your phone in download mode (Volume Down, Home and Power) then click home again to continue to download mode
    Launch the modified ODIN on your PC
    Unzip ENG BOOT file and get the boot.tar for your device (in my case it was the S7edge_qualcomm.tar was the file I needed for the S7 Edge) DO NOT UNZIP THE TAR FILE.
    Put that .tar file in AP section of ODIN
    Connect your phone, you should see a lighted COM port selected in ODIN meaning your good to go.
    CLICK START in Odin. You Phone will flash the file quickly and restart.
    Let it boot up fully and wait until you can unlock the phone (go to desktop of the phone)
    Now open a CMD prompt on the computer and navigate to where you downloaded and unzipped the SuperSU 2.79 earlier
    in the CMD prompt type root.bat this will push the required files to the phone and it will be rooted when its completed.
    After a few minutes your phone will restart, and you will have SuperSU and root access on Android 7.0 Nougat.

    This is how I rooted my SM-G935T Samsung Galaxy S7 Edge on Android 7.0 Nougat. Yes this is a bootloader locked T-mobile branded device.

    Please feel free to add or correct anything here in the posts below!

    EDIT: You'll want to install Kernel Auditor from the Play store, grant it supersu permission, and set both cpu govenors to ONDEMAND and set apply on boot. (core 1&2 default to performance and core 3&4 default to interactive - set both to ondemand and apply on boot)
    EDIT2: You may want to experiment with the CPU governors in Kernel Adiutor (that's actually the correct spelling according to the author). It's been suggested CONSERVATIVE will give you better battery life than ONDEMAND. So you'll want to try the available options and see which results in acceptable balance of performance and battery life for you.

    GOOD LUCK! AND THANK YOU!
    I HOPE THIS HELPS PEOPLE GET ROOT ON THEIR USA QUALCOMM DEVICES
    PLEASE TAKE A MOMENT TO THANK THE PEOPLE WHO BROUGHT THIS INFORMATION TO YOU.

    Returning to STOCK Android 7.0 Nougat

    You will need to have Odin installed (same modified Odin linked above should work fine)

    When you extract the .zip file for your device, you have 2 options for the CSC section. One file will erase all existing data and apps, reverting your phone to a like new state. The other will preserve your currently installed apps and data.

    CSC_TMB_G935TTMB4BQB1_CL10376601_QB12449118_REV02_user_low_ship_MULTI_CERT.tar USING THIS FILE WILL ERASE ALL EXISTING DATA ON THE DEVICE
    HOME_CSC_TMB_G935TTMB4BQB1_CL10376601_QB12449118_REV02_user_low_ship_MULTI_CERT.tar USING THIS FILE WILL PRESERVE (*NOT ERASE) ANY EXISTING DATA FROM THE DEVICE

    Obviously you can only choose 1 of the CSC files. Using the HOME_CSC keeps your existing data, and the other CSC formats your phone.

    Thanks to @billa (https://forum.xda-developers.com/member.php?u=293193) for taking taking the time to put these tips together for everyone.
    Slightly edited by me ;)

    Note (and suggestions)
    ----
    Before and after rooting wipe the cache.
    For tweak settings to stick, must reboot multiple times.


    Security Updates OFF
    --------------------
    Settings > Lock Screen > Security > Other Security > Security Policy Updates > OFF and Wi-Fi only


    Disable (things to disable after root - Use Titanium Backup or Package Disabler Pro for Samsung, both available from the Play Store - Worth the price to buy!)
    -------
    Samsung DM Phone Interface
    Samsung DM Service
    SecurityLogAgent
    com.sec.android.soagent
    com.wssyncmldm
    tethering.automation
    tethering.provisions


    After Eng-Boot (root is complete)
    --------------
    Install Kernel Auditor, and set both CPU govenors to "OnDemand" and set apply on boot.
    Set cores 1&2/3&4 to "OnDemand" and apply on boot.
    EDIT: Experiment with governor settings until a balance of power and performance is reached. Kernel Adiutor is available from the Play Store


    Performance tweaks
    ------------------
    GovTuner - set to interactive and performance
    Kernel Auditor
    Kernel Toolkit
    LSpeeds
    SSD Boost

    Set ro.securestorage.support to false in build.prop


    VOLTE/RCS icons OFF
    -------------------
    Copy the imsservice.apk from the root zip to
    /system/priv-app/imsservice/
    and set permissions to -rw-r--r--


    Data toggle
    -----------
    Use SQLite editor and add MobileData to a string in settings.db



    Busybox fix
    -----------
    Install busybox to /system/xbin instead of /su/xbin


    Sprint LTE fix
    --------------
    In Build.Prop change the following:
    ro.cdma.default_numeric=310000 to 310120
    ro.cdma.default_alpha=Chameleon to Sprint
    ro.build.characteristics=Chameleon to Sprint

    OR

    Click Cellular Network Preferred
    Go back two times and click on Mobile networks
    Select Network mode and select 3G/2G (auto connect)
    Restart your phone and call 611 just to make sure the call goes through
    Hangup and go back to Network mode and switch back to LTE mode

    As always THANKS to all the users who continue to contribute to this thread, and to all the people involved in bringing you this information so you can ROOT your Samsung Galaxy S7 or Samsung Galaxy S7 Edge on Android 7.0 Nougat!

    I will continue to update this first page with relevant links, details and information in an attempt to keep the information easier to find for everyone.

    Take a moment to press the THANKS button!

    So I've been running awesome here and I need you guys to try this root.bat file for me. This is the one I use and I DONT use any kernel editor apps or make any adjustments what so ever.

    Do NOT have any kernel editors or Lspeed installed when installing this please. Make sure you have the eng kernel installed. On your PC just unzip the file and double click the root.bat file to install.

    After phone reboots instantly power off phone and reboot to recovery and wipe cache partition then reboot.

    After power up let phone sit for 5-10 mins DON'T TOUCH IT, I KNOW ITS HARD BUT JUST DON'T DO IT!!!

    Reboot one last time

    Once it boots up open to home screen and just let it settle for a minute. DO NOT go into super su app, just leave it be!!! Open a app you know needs root permission and make sure the root prompt pops up. Let me know how the phone runs.

    Thanks

    Sorry about all the VOLTE Icon problems
    If your having FC issues your going to have to copy the original imsservice folder with imsservice.apk and oat folder to system/priv-app before you can flash this fix

    This new zip should fix fc problems as no apk is replaced no more just the icons are replaced inside the apk

    Volte Icon Fix Is now one zip for all S7 Variants. No more flashing wrong zip and getting FC. The zip only replaces Icons in imsservice apk. This zip will work on odex or deodex roms
    S7_VOLTE_ICON_FIX_ALL_VARIANTS.zip

    YOU MUST MOUNT SYSTEM IN FLASHFIRE WHEN FLASHING!!!

    I have a fix for the fingerprint scanner not working. Download the attached zip and replace the respective libs in /system and reboot. Make sure permissions are -rw-r-r-- (644)

    I guess I never really thought about that or looked into it but seems feasible. The eng.img does have some numbers for the description but not really like our firmware and BL identification sequence. I bet nougat for the regular S7 edge would flash on that active, you would be minus the active key. But it is kinda risky business if your only on BL 2.

    I'm pretty sure the original poster of the eng.img has the eng.img for the active, he said he has all the firmware for them anyways. Maybe try PMing him about it.

    Sent from my SM-G935T Running R.A.W root.bat! Buttery smooth, fast, no heat issues and great battery life!!!

    Wonder why it wasn't posted, when post for other devices. Besides I pm who I thought was original poster, but haven't heard anything as of yet. Been 24 hours so far. He might be busy.

    The engineering kernels and files are not meant to be released to the public, certain people have access to them for testing, coding, repair, etc... read between the lines. That's one of the reasons rooting using this method has such varied success... there is no 1 "cure-all" solution. Those files aren't really meant to be run for the life of the device by "users" on a daily driver phone. The files that are getting released, are more a less being leaked... not "released". So while "I agree" I hope they do surface sooner rather than later, I completely understand his/their hesitation in releasing them... Just read thru this thread.... some people have had great success, others have had complete failure... Most people don't even want to read thru the OP for details, let alone the thread to gather information.... they just post a question that's been answered before - sometimes right above their post. :( or people complain the instructions aren't labelled clearly enough, or links to files aren't easy to find, or using this method cause batteries and screens to burn out... One poster even said his rooted phone worked fine in the house with the AC but failed miserably outside in 80f heat... :crying:

    We all try to assist, we all try to help, we all try to contribute.... but at the end of the day - each user HAS TO PUT IN SOME EFFORT. And everybody HAS to realize, rooting (by any method imho) is always done at the users own risk. There is no guarantee given or implied. Results are obviously going to vary - and for guys who don't understand what they're doing - the results are ALWAYS going to be questionable. ** I AM NOT COMPLAINING ON ANYONE ** I'm just saying having root on this device period has been a stroke of luck with a touch of genuine genius thrown in for good measure (NOT BY ME - BY THE GUYS DOING THE HEAVY LIFTING - THEY KNOW WHO THEY ARE)

    I truly hope everyone is able to obtain an acceptable level of performance and usability while gaining root access. That's the goal for everyone in this thread.
