Here's how I ROOTED Nougat on my S7 Edge G935T

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://xdaforums.com/tmobile-s7-edge/development/rom-t3572739

@jrkruse for his awesome job for making a custom flashable Android 7.0 Nougat ROM https://xdaforums.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://xdaforums.com/showpost.php?p=71271898&postcount=28 )
https://www.androidfilehost.com/?fid=457095661767141717
(This is the ENGINEER boot kernel boot.tar file you'll be flashing in the special modified Odin software from your PC)

*edit: newer method available!* SuperSU 2.79 root.bat file (from this post https://xdaforums.com/showpost.php?p=71281527&postcount=50 )
https://www.androidfilehost.com/?fid=817550096634750763
(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)
Nougat_S7_Root_2_82_All_Carriers_V1.zip

jrkruse said:

This root method will reset your fingerprints and lockscreen security it will also fix fingerprint issue this should help with issues of not recognizing your fingerprint after you root. I had to modify the latest SuperSu to get root to stick on SuperSU 2.82.
Here is a what I did:
The new supolicy from 2.82 Version was causing root not to stick. So I used the supolicy from 2.81 Version. I modded the SuperSu.apk to ingnore the supolicy not being 2.82 Version So you wont get asked to update the SuperSU binaries.
The SU binary is updated to 2.82 and all other files.
If you delete SuperSU apk dont reinstall it from playstore use the one in Above zip

PLEASE REMEMBER: Results for rooting vary on each and every device. Lag, Performance, Heat - These things vary from device to device. YOUR MILEAGE WILL VARY!

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

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://xdaforums.com/member.php?u=293193) for taking taking the time to put these tips together for everyone.

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!

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

Click to expand...

Click to collapse

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.

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.

Click to expand...

Click to collapse

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:

vazquezcmp said:

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.

Excellent.. Glad it worked.

Quickvic30 said:

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 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




Sent from my Pixel XL using XDA-Developers Legacy app

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?

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

Click to expand...

Click to collapse

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?

Click to expand...

Click to collapse

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.
