[Q] Little help (i am a noob)

Hey... I have a Samsung Galaxy S4 (GT-I9505) with 4.3 firmware..
I rooted it just a while ago with no custom flash rom or anything.. just a simple root.
Now you all might be aware that samsung s4 has this thing for security called Knox.
I was trying to use SuperUser and it got blocked. Well eventually i used it to grant permission to Game Hacker. But for some reason it kept popping up and repeating " Root access granted" like it was being blocked and released again and again.
My question is, Is Knox blocking my attempts to give root access to apps? is there anyway i could bypass this so called Knox?
P.s: i dunno if i set the eFuse off. anyway i could check if i have voided my warranty?

To check see if you've turned knox 0x0 to 0x1 go into download mode and it'll be on the left hand side of the screen.
Can't tell you about the superuser access like

Open the supersu app, it will have an option to automatically always grant
root access permanently without asking.....
Good luck!

New to Samsung devices, but just need to make sure

Hello all,
This is my first Samsung device, the Galaxy S7 Edge Dual sim (SM-G935FD) bought from UAE.
I used to install TWRP and root every android phone I had before, so I am still not sure whether to root this one. I already have the files required for rooting, but I noticed that there are 2 ways of rooting:
1. Using Odin to install TWRP and then from there install SuperSU.
2. CF-Auto-Root.
What is/are the difference(s) in both methods?
My other question is: I read that rooting will trip Knox, and there is NO WAY to get it back to normal even flashing the original ROM. Is that the case?
One last thing, I am now stuck in the download mode (turned off the phone, pressed "Volume down", "Home" and "Power"), I did that just to check the info on the top left (model and warranty void...) but I cannot seem to restart the phone even by pressing the power button for more than 20 seconds, how can I turn the phone off then back on?
Thank you
*****EDIT*****
Regarding my last question (stuck in Download mode), pressing the same combination got me back to start the phone normally

Cf-AutoRoot will root your phone but then you will have to put your recovery on also usually flashed with Odin anyway or an app if it's working for the Galaxy S7... Twrp plus superuser will root and you'll have the recovery installed.... They both will trip your official (0x0) knox and make it (0x1) custom.... You can always go back to stock rom and get OTA updates but your knox will remain at 0x1......this is supposed to void the warranty but depending on where you live it won't make a difference.... Also if you want to flash roms and mods and kernels just use the twrp method and if you just want root and to be able to use root permission apps use the Cf-AutoRoot.... As of right now I haven't rooted because there aren't to many Roms available... I'm sure I will cause I miss titanium backup and the ability to get rid of all the bloat ware (especially Facebook & Microsoft ****).... The phone runs great without root and battery is excellent.... The last reason I was waiting was Samsung pay won't work with tripped Knox counter.... I live in the US but have the international 935F... So it doesn't look like this variant will support Pay anytime soon.... Probably gonna root when development picks up a little....
*edit*... Always have a stock rom just in case saved to your computer just in case... That would of saved me lots of freak outs and headaches years ago... Now it's the first thing I do before Rooting or flashing anything to my phone

Thank you for the detailed reply.
I made a research yesterday on Knox (as I said, this is my first Samsung device), and I just wanted to make sure that I understood things properly.
So now after reading, tripping Knox will disable Samsung Pay (I do not have it in my country) so that is not going to make any difference. But, what about paying using the fingerprint sensor in Google Play, will it stop working if Knox is tripped? I also use the fingerprint sensor to login to my mobile banking app (instead of typing the password every time I want to login), will that stop too? I guess not but again just to be sure.
Thanks a lot once again.

I know when I rooted my S6 all the fingerprint stuff still worked so I dont think it will make a difference... Im not sure with the S7 edge but I would think it would still work cause all of those require a typed password before you use your fingerprint(1st setup only) Then use your fingerprint there after... .. Doesn't have anything to do with Knox

yep, it all still works. just Samsung pay & private mode.

Accidentally deleted Knox app

Hi everyone!
Today I did a stupid thing- I'm going to factory reset my phone and was looking for a way to backup my Knox data. Sadly, I found an outdated link to a Samsung site that said I will get a prompt to backup when I uninstall the app. Without much thinking, I hit "Uninstall". To my terrified surprise- I didn't get a backup prompt. I quickly installed Knox again, but the data was gone.
Is there any way to retrieve it? The phone isn't rooted or anything, running stock FW.
Many thanks for your help, I greatly appreciate it

I don't know.. but maybe Smart Switch? Try that.. also I don't understand how the Uninstall can backup something.. when it's basic uninstall

The whole purpose of Knox is that you cant recover anything from it of you uninstalled it or tampered your device. Ever.

Heeeeeellllppp!!!
I rooted my Samsung Galaxy S3 with kingroot. I wanted to replace it with SuperSU using SuperSU me. So I deleted a few things from Knox including Knox migration agent trying delete Knox completely to make it easier for SuperSU. Well I didn't have any problems until I did the final reset to install super su. Now when I boot up I continuously you get the air Knox migration agent has stopped. It won't even get to my password screen. Anyway I can download a Knox migration agent zip to my SD card and install it via recovery? Please helplll£

Flash stock rom?

Does installing stock firmware reset knox?

Just wondering if installing stock firmware using Odin resets knox. I of course tripped it without even knowing what it was, and it looks like my banks mobile payment option requires knox 0x0 to work. I've looked at lot of posts on here with regards to resetting the knox counter, etc, but they are pretty outdated and most of the files required to accomplish it are long gone. If anyone could point me in the right direction it would be so helpful. I don't care about having root, I'd prefer to stay on the custom rom I'm on, but if that's not possible I'm willing to go back to stock. I noticed a lot of the threads are asking how to keep root while resetting the knox counter, but I just want to know if installing stock rom will do this for me.

Did a little digging and it looks like its impossible to do. Oh well, mods can close this thread.

Knox so important?
Even my note 3 got 0x20 count i will no bother if no abnormality happen..just carry on and live with it

I think it's only possible on the Exynos version, not on Snapdragon.
As for your bank, maybe it only detects root, NOT knox 0x1
So, you can try Magisk root method instead of the traditional SuperSU, because Magisk can hide root from a couple of apps that detect root, like Google Pay

Temporary Root possible?

I have a Samsung j5 2015.
I want to temporarily root it.
After I restart my phone, I want it to act like it never was rooted. Ever. If I give it to my carrier, even, and they investigate it, they won't be able to find it. its status also must be official after doing this.
Is this possible? I don't need a custom ROM or anything, I just want to remove the pre-installed crapware.

just root it and unroot if you dont want it anymore, its that simple(but it might still void your warranty but eh)

That's not much problem my device warranty is already voided. The problem is when i root it it shows root failed i think its is due to locked bootloader. I want to unlock bootloader without wiping data. Is it possible...? @dankfrank33

btw what android ver are you using? did you root it thru twrp(flash method)?

6.0.1 Marshmallow
What you suggest me how to root it...?
i tried kingroot and kingoroot it failed always...
