[Q] Rooting Verizon Galaxy Note II 4.3 after tripping Knox and 4.1.1 downgrade

Okay guys. Here we go. I screwed up the other day while trying to load a custom ROM following a friends instructions. I tripped Knox on my Verizon Note II 4.3 and was forced to downgrade to 4.1.1. My phone is no longer rooted and I am trying to figure out how to root from 4.1.1 with a locked bootloader and then use safestrap to install custom ROMs. Sadly I cannot find any info anywhere after several hours of searching. I've read up on Knox and I could care less about warranty info (I bought the phone used after all) and I just want to be able to load custom ROMs so I can better enjoy my phone while being able to restore APN settings since I am running on a non-Verizon carrier service. Please help!
Edit: I used RootChecker to make sure that my phone is no longer rooted after downgrading to 4.1.1
Edit: Fixed with Kingo Root

Used S6 and have no idea how to root

I've researched multiple rooting tutorials and have found a lot of guides based on the auto-root file from www(.)autoroot.chainfire(.)eu
However, I still do not know what to do with this. From my research I found out that there is a possibility that the bootloader is locked and that is the reason I am scared, if I brick this phone I will not have a phone for another 2 years. If I flash a new clear android 7.0.0 stock for the S6 without the O2 addon bloatware with the bootloader locked it will brick my phone since this is some sort of security feature.
What I want from my S6:
- VERY good security, I will be banking on it alot, using android pay, etc so I need it to basically be hack-proof etc. Im not going to install apps like lucky patcher which are not from the play store.
- A new clean stock version of Android 7.0.0 without so many O2 apps that I cannot uninstall.
- Root access to remove certain system services and increase my battery life
I am a previous root user, 1 year ago being on my rooted S3 which I rooted using KingoRoot with one click. Now I come back year later to a new phone 3 generations down with things like the locked bootloader and KNOX. Could anyone explain what I can do at this point?
Phone specification essentials:
Name: Samsung Galaxy S6 O2/EU
Model Number: SM-G920F
Build Number: G920FXXU5EQE5
Android Version: 7.0
Knox Version: 2.7.1
The device still has a simlock, and I was told that the sim lock is installed in the ROM. So if I were to flash Im assuming the simlock would be removed however I still have a pending order for the unlock code coming in 7 days.

Try with a TWRP and a Magisk' - SuperSU it's a will be less-stable for now' (Seriously who are be use at This for now?)
Addition advantage it's a doesn't Permissives of a Magisk (Still "Enforced")

rooting VVRS4 ?

Hi,
I just bought a Like new S6.
I thought I was getting a factory unlocked device, but I got a Verizon unlocked phone (for other carriers) and full of bloatware from Samsung and Verizon.
I can still return it, but before doing so, I was looking for options about rooting or installing a different ROM.
it has Nougat 7.0, Firmware G920VVRS4DQI1, Kernel 3.10.61
As I understand, currently there's no way to modify anything in this model, right?
Should I return it?
Thank you for your replies

What's the safest way to root & possibly BL Unlock my TMobile Galaxy S6 SM-G920T?

I'm new to posting to these forums, so forgive me if i don't add the right tags or do something right...
Anyway, I was given a TMobile Galaxy S6 as a hand-me-down phone from my family, and wanted to know what was the best way to root the device. I don't really care if i trip Knox, but i'd like it to be unnoticeable, and i'd love to not trip it at all, if possible. I don't want to have an "Unlocked" sign everytime i bootup. I want to be able to run Vanilla Oreo (or close to it) without touchwiz as the phone has been getting laggy, and since i already have another Rooted Device, it's not laggy when running Resurrection Remix, which i'll probably end up running that ROM on this phone as well. I've heard the TMobile version has a Bootloader unlock, but i'm not sure how to go about doing that without bricking the device. The reason i'm asking is because the last Samsung device i had, a Galaxy S5, was bricked for a number of months before i was able to flash stock again using a SD Card, and i don't want to have to go through that again with this phone. Should i just follow this tutorial? or is there a better way to flash without tripping Knox? I know how to root & BL Unlock, i've done it on a number of close-to-stock devices, but Samsung devices are a whole 'nother world of trouble that i don't even know how to deal with.
Device: T-Mobile Samsung Galaxy S6 - SM-G920T
Running: Android 7.0
Build Number: NRD90M.G920TUVU5FQG3
Baseband Version: G920TUVU5FQG3

I have the same phone ,first go to developer option and allow iem unlock ,reboot to odin and flash cf auto root (choose the one for your modele and os exactly) then reboot

Sprint S7 with 7.0

Ok so today I went to boost. I bought an S7 with 7.0 on it,
What ways would I go about rooting this, upgrading to OREO and etc. The security patch is also from November 2017.
The reason I'm asking and not just jumping right to it are
1)I know if I update at all there is no root with Sprint.
2)I'm not sure if I'm on a version low enough to unlock the bootloader if I need it.
3)I'm open to unlocking the boot and flashing a 8.0 rom if possible.
Any guides would be greatly appreciated
