PROGRESS THREAD:

ORIGINAL ATTEMPTS (For documentation and debugging purposes)

I tried rooting with the version [B][I](Samsung_G930x_QC_Rooted_BOOT.TAR)[/I][/B] in this thread. Unfortunately, resulted in boot loop.

PHONE: Verizon S7 G930V
OS: G930VVRS4BRA1

I went back to recovery mode [I](turn off phone, hold volume down, home, power)[/I] then instead I used this eng_boot [B][I](S7_Qualcomm.tar)[/I][/B].

It fixed boot loop and now I will try to do supersu
Update:
ok so i downloaded the supersu at here [url]https://xdaforums.com/verizon-galaxy-s7/how-to/how-rooted-s7-nougatand-fixed-lag-t3576393[/url]

It is a lot of files in there. Don't worry.
* Extract supersu zip from [I][removed, see correct below][/I] all to a folder.
* With phone still connected, (regular, NOT in download mode),
* Right-click [B]root.bat[/B] file and run as administrator.

It will open command prompt.
You will need to unlock your phone (swipe the screen) and click allow to access in the popup you see.

It will take a few seconds and automatically reboot.

Now i need to check if it worked. I'm going to install a root checker see if it's rooted.
Update: I saw supersu wasn't installed. So I dragged over .apk file from the folder above and installed on the phone manually.

Supersu binary is updating. Will see if it works.
Update: Installation failed. Reboot

Failed.
I will attempt to run the root.bat when in recovery mode...
no luck.

uninstalled supersu.

now says custom.
EDIT: KNOX IS NOT TRIPPED only system status says custom. I installed samsung knox status and it is still 0x0.

ran unroot.bat

This time I tried the SuperSU-v2.74-2-S7QC from this thread.
rebooted.

Supersu installed. Looks ok. May be rooted.

Will check...
titanium backup request root ok but is not successfully freezing system services.
Root Checker agrees [COLOR="SeaGreen"][B]Success[/B]![/COLOR] that root is achieved.

However, even though supposedly have root, am unable to freeze system apps in titanium backup.
Triangle away also isn't working, maybe not supported device.

Unsure if I have full root or not.

still checking...

Now I want to change system status back to official instead of custom.
I'm going to try a factory reset. Since I have nothing on the phone yet that's fine.
Please be aware I got a Verizon certified phone and they Disabled FRP (I saw so on the fastboot screen)
... doing...
Did not work. Still says Custom.
need help on this how to set system status back to official when Knox is still 0x0

This time after factory reset I tried the [URL="https://xdaforums.com/verizon-galaxy-s7/how-to/how-rooted-s7-nougatand-fixed-lag-t3576393"]supersu 2.79 from here[/URL] again, but this time I used root_with_tweaks

This time, that one worked. It was also able to disable knox after opening supersu after phone rebooted.

let me try titanium backup again (after factory reset I have to reinstall it again)...
Root Checker gives [B][COLOR="SeaGreen"]Success![/COLOR][/B]
Knox Status gives [B][COLOR="seagreen"]0x0[/COLOR][/B] (not tripped)
Installed TitaniumBackup - tried to freeze SecurityLogAgent - [B][COLOR="SeaGreen"]Success![/COLOR][/B] It worked.
Ok, now all seems to be in order!

Only thing left is to change my System Status: Custom back to Official.
Any advice is appreciated.

Update: made a mistake. Tried to install xposed without fiollowing directions. I tried to install apk first. Now, phone will not get past the white verizon loading screen.

Attempted factory reset. Didn't work.
Cleared cache. Didn't work.
Tried to factory reset a couple more times. Didn't work.
Re-flashed entire original OS. (same BRA1 version as my phone had before).

============================

REFLASH OS BACK TO STOCK INSTRUCTIONS:

Get OS from here https://androidfilehost.com/?fid=746010030569958815

(original source to link)

When I extracted, winrar gave a file corrupt error. I saw the same from others and was worried about it.

Still, I took a chance.

But I unzipped with 7zip. The error in 7zip said corrupted header.

I used anyway, it worked fine in the end. I used this successfully for reflashing several times by the way.

On phone, hold all buttons while phone is on or booting, even in bootloop this works. After about 10 seconds or so it will shut down and open recovery.

Do a Factory Reset.

After it completes the blue erasing screen, it will reboot.

Wait to finish.

Setup like above disabling and enabling certain options.

Turn off (hold all buttons for 10 seconds or so).

Enter Fastboot (Home, Power, Vol Down).

You are now prepared for flash.

Add all the files, in PrinceComsy Odin 3.12 (from this thread)

BL

AP

CP

CSC

Appeared to still not work, and showed Custom still on reboot, (but it did work in the end, please read below)

But then I powered off (you hold all buttons to power off by the way) when it was stuck on white verizon boot screen, and this time entered safe mode. Safe mode worked. I got past the boot screen and now at phone setup.

NOTE: Be aware that after reboot after reflash OS, this white loading screen can take some time. It took a few minutes (but not 10, maybe 2 to 4 minutes on first reboot after flash to stock - longer than usual but not excessively long. Be patient.)

SUCCESS! After booting into safe mode after the full reflash of OS, it came into the phone setup. I said skip to everything.

Did usual things:

* Enable Developer Mode (Settings > About phone > tap multiple times on Build Number)

* Developer > Enable USB Debugging

* Developer > Disable Auto Update System

* Developer > Disable Verify apps via USB

* Lock Screen & Security > Enable Unknown Sources

* Lock Screen & Security > Secure Startup > Ensure NOT enabled

* Lock Screen & Security > Other Security Settings > Disable Send Security Reports

* Lock Screen & Security > Lock Screen > None (only for testing at this time, not sure if it helped with fix but just documenting what I did)

Then, after performing above, I decided, well I can't use phone in safe mode anyway, so let me see if this works. I decided to reboot at this point.

On reboot, CUSTOM GONE! PHONE BOOTS LIKE NORMAL!! FULL SUCCESS!!!

(UPDATE: I think you HAVE to enter safe mode after reflashing as soon as the white verizon loading screen comes up, if you want to fully reset to remove Custom. I can't be positive, but I didn't enter it the third time I reflashed (because I'm trying to choose a root that doesn't cause "Custom"), and it left Custom. Then I finally reflashed again and shut off on the white verizon loading boot screen and entered safe mode, and then set up like above, rebooted and Custom was finally gone again and factory settings. I had also gone into recovery and cleared cache before this, so I'm not sure why I had trouble on the third time, but I am back in business again now.)

=================================================================================

Now, back to starting from scratch like I just got the phone again...

... working...

G930V ROOT INSTRUCTIONS

1. For good measure, considering all the above, I rebooted again.

Boots perfectly. No Custom, completely Official at this point.

2. Enter Recovery Mode.

* Turn off phone

* Hold Home, Power, & Vol Down until it vibrates.

* Press up for yes on the blue screen asking you sure you want to install custom OS.

3. Install Engineering Bootloader

* Use PrincyComsy Odin 3.12 to install engineering bootloader.

* Use file: S7_Qualcomm.tar from here

* Open Odin, click AP, choose file S7_Qualcomm.tar from above.

* Click start.

* Wait for it to reboot.

4. Rooting

* Once booted ensure you unlocked the screen. Phone needs to be on for this.

* Download file SuperSU from here

* Unzip S7_SU_2_79_Root_Unroot_WO_Tweaks to its own folder.

* Ensure you unlocked screen, phone is conneccted, and you clicked Allow to access file on the normal popup.

* Run as administrator: root_with_tweaks.bat

* Wait for it to restart.

* Unfortunately, at this point I get Custom. I'm going to start over again, this time try the 2.76 to attempt to root without custom. Using above instructions I will wipe the device and back to stock BRA1 version.

* It's worth noting, though, that it is indeed rooted at this point.

5. Rooting Attempt 2 - trying to not get Custom

Note: After I wiped again back to stock (see above instructions for that), this time I am trying 2.76QC version to see if that will work to not give me Custom system status. If that doesn't work, I will wipe another time and then try the 2.74QC version.

* Once booted ensure you unlocked the screen. Phone needs to be on for this.

* Download file SuperSU-v2.76-S7QC.zip from here

* Ensure you unlocked screen, phone is connected, and you clicked Allow to access file on the normal popup.

* Run as administrator: root.bat

* No luck! Rooted successfully, but says Custom again. At least now you don't have to experiment since I did for you.

5. Rooting Attempt 3 - trying to not get Custom

* Once booted ensure you unlocked the screen. Phone needs to be on for this.

* Download file SuperSU-v2.74-2-S7QC from here

* Ensure you unlocked screen, phone is connected, and you clicked Allow to access file on the normal popup.

* Run as administrator: root.bat

(* ok I'm finally back... trouble getting it reset and reload OS to stock the third time but I am back to stock with Official.)

* moment of truth --- NO LUCK. darnit. It is rooted, but shows Custom on reboot.

Ok I am just going to give up on removing Custom. It seems that it's going to detect root no matter what. I'm going back to the 2.79 which seems a more stable root. I'm going to the "root_with_tweaks.bat" in the S7_SU_2_79_Root_Unroot_WO_Tweaks as in Root attempt 1 above.

I guess I will have to live with this Custom until TriangleAway gives an update to fix it on S7 (if ever).

At least now you guys know for sure that all 3 roots will all show Custom even from a stock no Custom factory device.

Knox still OK.

2.79 supersu from above does successfully disable knox when you open it up, which is convenient.

Next steps: titanium backup, and attempting xposed this time. At least now that I reflashed several times I have a clear picture of what to do and a stable method to recover from frozen boot or bootloop.

Update: I tried to install xposed using flashfire and then installed xposed installer afterwards, but it is still saying that xposed is not installed. Maybe I need a different apk? I used the official 3.1.2 apk for xposed installer.

Update: I got a newer xposed installed than listed.

Working great.

Phone fully rooted.

Custom ROM.

Custom boot start screen. Verizon boot removed.

Black everything - no white not even on boot or shutdown.

Fast phone.

Titanium backup disabling services.

Currently working on full customizations.

Full Success.
