Unroot/relock with custom firmware - Samsung Galaxy S7 Questions and Answers

Hi there,
I've installed LOS 16 on my Galaxy S7 and I want to use my banking app on it. The problem is that the app says the device is rooted. I guess didn't root it. In download mode is written:
product name: SM-G930F
current binary: Custom
system status: Custom
FRP lock: OFF
Secure Download: Enabled
I also searched the internet for a solution but the only way I've find i to flash the stock firmware.
Is there any other way to relock the phone with LOS on it?
Thanks for your help!

The knox counter has tripped, it can't be reset, it doesn't matter what ROM you put on it now most banking apps will never work on the phone again.
Sorry buddy.

Probably it is such a Samsung specific problem. I've installed LOS on a Xiaomi A2 lite and the banking app is usable. So there is no way to revoke the root permission?
Edit: On my old HTC One m8 with LOS 16 it works also fine.

Yes of course you can revoke root by going back to stock or a custom ROM based on stock but not on LOS as its a totally custom ROM.
With regards to banking apps working, some do, most don't. It very much depends how that app makes a secure connection and if the provider is happy for it to run on a modified device.
My HSBC app works on my phone but that's the only one all others I've tried give the message "this device has been modified / isn not secure" etc. and won't run.
It's not the root that prevents this, it's the fact that when you root a device you trip the knox counter which cannot be reset because its a hardware fuse not software.

Thank you for your reply.
The fact with the hardware fuse is known and it should be not the problem with the banking app. Like I wrote it works with other devices which are already unlocked. Probably It is the custom ROM which is not based on the stock ROM.
I will try to install an other ROM based on stock ROM without the annoying pre installed apps.
Many many thanks for your help!

Help with Rooting

I'm looking to root my phone, but I have a few questions. I just want to make sure I'm using a method that will work for my phone as I seem to have an uncommon version. I'm on a small carrier, and I'm questioning how I can root without tripping KNOX. Every guide I've found seems to indicate there are questions about rooting my phone. My build version also never shows up on any of the guides as a supported build.
Relevant information:
Galaxy S6
Model: SM-G920R6
Android Version: 5.0.2
Baseband Version: G920R6WWU2AOF2
KNOX version: 2.4
Anyone able to point me to a root that will work, and not trigger KNOX? Any guides are welcome as well!
As far as I know there isnt a way to root without triggering knox , and if you want to root you could probly find a guide quite eaisly , if its that you want to still be able to use knox secured apps etc use magisk

I tried PingPong. It notified me that it could not complete (I assume because I have an unsupported version).

Will Android Pay still work with magisk? I'm not familiar with it. I was under the impression that I would be permanently unable to use mobile payment applications if Knox was triggered. Is that wrong?

Yes it will , enable magisk hide and it should work , android pay dosnt use knox , i think samsung pay does but android pay is not effected by knox
Install magisk and it will all be fine
Also for rooting , just flash twrp with odin then flash magisk for root etc

The fact you are on a s7e port which is a custom ROM means you had already tripped knox permanently, any app that required knox will not work anymore such as samsung pay, you can hide root via magisk and magisk hide, but just to reiterate once you trip knox it cannot b3 reversed

You're not understanding what I mean, once you trip knox by installing a rom like s7e port, doesn't matter if you return to stock rom, knox will remain tripped. You won't be able to use samsung pay at all because knox is permanently tripped, shealth should still work though, I'm in stock rooted MM, so can't confirm everything

You can use custome roms to gain access to shealth.
Im using Noble nougat 4.0 s8 port, and works great.
Hi.
You still can use SHealt
This is how (of course you need root access) lint to post
Sorry but you can forget to use Knox after you tripped Knox flag.
Try root with Magisk - this allow you to "hide" root from some apps.
PS
Sometimes root is not a bad thing...
Setting ro.config.tima to 0 fixes SHealth. For the Samsung login you'll need to read this, https://forum.xda-developers.com/showpost.php?p=71566173&postcount=6

Flash stock recovery after that your device will return to official state then you will be able to check or upgrade via OTA.

Rooted phone?

Okay so my device is Galaxy S7 and I had it rooted and running LineageOS for a few days. Because of security, I decided to install stock firmware using Odin. This runs well as stock. Play store and phone info sata this is certified and official software. SafetyNet gets everything passed and says no root. But still my Samsung apps cant run, since they think this is rooted... What to do? Can there be some files left?

Did you flash with Odin?

After rooting your phone warranty will be set to 1.
You can check by going to download mode and reading the property : Warranty void
If its a 1 you can never use these apps again for security reasons

This isn't correct, once you flash back to stock with Odin the security is restored. The knox counter trip means the warranty is void because the phone had been rooted etc

Yes it is. The apps dont check the status of your phone they check ro.boot.warranty_bit

I downloaded the nordic country most recent one. So I guess its 8.0... And got recommendations for SamMobile. And yes, I used Odin to flash this firmware.

Samsung Galaxy S7 (SM-930F) displaying "security log agent" notification after root

Is this something that happens when you root a Samsung phone or my device has been compromised by shady software?
It is my first time rooting an smartphone and it seems that bank apps won't allow rooted phones. I am thinking about flashing an official rom to fix these issues.
By the way, I used this guide to successfully root my device:

If you are on the stock rom then yes, it will show security log agent notif.
And you wont be able to use banking apps on rooted phones on any rom official or unofficial.
You can try using magisk hide but i've never tried it so not sure if it will work.
