Is there a ROM with Knox enabled? - Samsung Galaxy A50 Questions & Answers

Hi, I have a custom ROM on my A50 (Fresh Rom) but I want to reinstall a ROM that has working Knox (vanilla if necessary). Can someone point me to the right direction please? I need that to be able to access some company resources...

I don't think you'll get a working Knox, on most Samsung phones once you trip Knox you can never recover it unless you change the motherboard.

On most if not all Samsung devices (My Samsung S5 has this so I doubt the A50 won't) once knox is tripped (Rooted) an electric FUSE is blown , once blown it can never EVER be "unblown" unless you replace the entire motherboard as the FUSE is most of the time inside the SOC itself.

Yeah you're boned... but don't piss where you drink.
Best solution is to use a dedicated company phone. 100% tax write off too.
I hate Knox.

Knox?

I've been "out of the loop" for quite some time and much has happened to Samsung devices since my last one (Samsung i9000). Basically it is the terror stories about this Knox security thing that mostly concern me and brought me here...
I mean I like this tablet, I trully do, but if I'm robbed by android's main advantage (modifying the thing to suit your needs) then I have absolutely no reason to choose this.
I have already read a a couple of stuff but they are all concerned about s4 and note 3. What about this tablet (the WiFi version), is it ... secured too? Also I'm a bit unclear of what this Knox thing achieves, at first it voids your warranty, second does not let you to flash certain ROMs, but I'm unclear from/on which ROMs this is enabled or even if merely rooting your device would enable this. I mean someone may not be interested in aosp ROMs but still love some "optimized stock + custom kernel" will this Knox thing prevent him even from that?
If this is proved an unmodifiable device I'd think twice for it's usefulness, android's only edge is its "modifiability" remove it and you buy sth 2nd or 3rd tier...

You can still root and modify things, however, Samsung has taken the stance that since Knox has been tripped you must've been running Custom firmware/apps that can "potentially" damage the hardware so all warranties (at least from Samsung) are void....
The other issue is Samsung are updating bootloaders when you install firmware updates. If you happen to get a new bootloader then you CAN'T go back to a lower version of firmware, period... Doing so generally results in bootloops or stuck on Samsung logo until you update to the newer firmware again...
The downside to this is the nandroid backup you took just before updating in case of a problem is rendered useless, and in the case of the Note 3, Kies no longer recognises the new bootloaders so emergency firmware restore doesn't work...
Knox also tries to deny any app root access, some messenger programs were denied access as their permissions required root access. SuperSu has been updated now to work with no problems, until Samsung decide to interfere again....
Knox is also a secure container for your data, it was meant for security agencies and such to have a secure passworded partition in the software that doesn't allow anyone but the person with the passcode to access it. This is disabled after rooting as the system has been modified and can no longer be deemed secure....

So Knox is more about controlling your device than security as it is not optional (you cannot turn it off , right). Also about losing the warranty, well I was hoping to buy it from a reputable store in my country, even if Samsung voids my warranty can't the store itself honor it?
If not, if in fact merely rooting your device voids my warranty whatsoever than I'm most certain that this is not a device for me and I'm not sure for whom it is, I don't think android is a good os when decoupled from rooted apps (no xposed framework, no adblock, no virtual buttons, no gestures, no greenify), the experience is basically killed...
Even jail breaking your iPad doesn't kill the warranty as long as you install non jail broken iOS version on top... Bad Samsung, bad
OK, since I actually want to give this tablet a go I came up with a new idea. What if I trip up the Knox counter but then get back to stock firmware and *then* my tablet gets damaged? Would then my warranty be honored? The Knox counter can only tell you that it was tripped *once* but not what is/was happening at the time you got a defect.
Maybe my battery died, or more than a handful pixels died on me, all having nothing to do with me rooting my device at some point. Can my rooting still be grounds for samsung to dismiss my warranty? Because if so that is quite a scheme that Samsung runs.
Do any people had their warranty honored even though the Knox counter was tripped?
If you have a squaretrade warranty you should be fine with that excuse. However, Samsung will say that they cannot tell if the damaged occurred before or after the rooting occurred, thus denying you your warranty. Once the counter is tripped, from that point on the warranty is gone. My recommendation, get a squaretrade for 100 with a 2 year warranty and you will be fine.

[Q] warranty after root( what about knox)

So I know how to root and unroot and how to use triangle free but I heared about knox software and they say it can be tripped
So I unroot &uninstall root software, use triangle and put stock firmware from sam firmware website back on.
Is my warranty back on at this point or they can check bootloader and knox to find out that I have rooted before.
If its not back tell me what else to do.

Tripping knox isn't reversibel.
But usually that doesn't matter in warranty cases.
If you have a defective device and have knox tripped, you should be fine as it wasnt your fault. Someone( xda user formeriphoney) had a faulty power button, then later and faulty chip or something cuasing it not to turn on. He get it all replaced by samsung and he was even running cm11 when he sent it to him.
Basically you cant untrip knox. And its a 50/50 chance of samsung servicing it because of an defective part.

So whats the point of unrooting and using triangle free if they can figure out that you rooted your device from checking knox records?
Anyway on my new tablet I cant even find knox maybe it's not protected by knox???. (Galaxy s4 phone has it and its visible)
Thanks for helping

Triangle free wont work. Newer devices have a knox that cant be untriped.
To see knox status, go into download mode and it should say "knox 0x0" and if you triped it it should say "knox 0x1"

Would never think about rooting if google hadn't messed with kitkat's sd card permission. Hate google
New to all this but I was worried to root my new device because I keep hearing about this knox. I got a feeling my device will need warranty one day. The power button is just so flimsy I can't see it not breaking, getting stuck. I wouldn't think it would matter if I messed with the software and a button got stuck but you never know. I would hate to give them an excuse not to fix it if something goes wrong.
On a side note are the buttons a easy fix?

In Europe tripping knox won't do anything to your warranty.
However, opening the device just to fix the buttons might harm your warranty, so I wouldn't do that myself.

I think I really want to root this device. I wonder how they treat warranty claims in Canada, I'm in Toronto.
I was asking on how easy it is to fix smaller things on the device so I can make a decision on if I should root. If its fairly easy maybe I'll take my chances and if anything happens I can try to fix it myself. We also have a lot of small repair places around here that can be fairly cheap, as long as nothing big happens.

Samsung Health & Pass not working!

Hi. How r u doing?
I have been rooted the device and remove it and flashing the stock firmware. But, the problem is I cant use the Samsung health or Samsung pay or Samsung pass. I see some solution but it needs to root the device again! and I don't want to root it again.
If anyone has a solution to my problem please help me.
Thanks.
You blew the efuse when you rooted it. The efuse is a micro chipset "fuse" similar to those used in a PROM, it's a one shot deal.
Programmable ROM - Wikipedia
en.m.wikipedia.org
The stock firmware and/or Knox apps sees those flagged apps. The knox based apps are designed to be hard to hack. A modified Samsung Pay could be a security risk even if you could do it.
I don't think you can modify that on a stock rom; it's hard or impossible even on a rooted device.
Find a work around on your rooted device and be happy. If you want stock, replace the mobo.
Someone here might have a better plan for you though as I haven't played with this. There are others here looking for similar solutions, if you find any post them.

Tripped Knox with unrooted device

The other day I thought it would be a good idea to root my phone (S20 Ultra Exynos), as it's been many years since I've done it (S6 was my last rooted device).
Anyway, I kept running into issues with connecting to my watch, and getting payment apps working (on account of the root), and decided it was not worth the hassle.
So I unrooted the device via flashing stock firmware in ODIN and locked the bootloader.
I noticed my Samsung Health app didn't work, which was strange. Upon research, I found it was due to Knox being tripped - which was confirmed via downloading a checking app from the play store.
I know that there are patched S Health apps that would allow me to bypass knox, but is there is any way to reset the knox counter so that warranty is no longer void?
Are there also any other implications from this.
So far all my apps work fine, except for health.
Cheers!
It's a micro efuse inside the chipset that blows when you trip Knox.
The only way to fully undo it be to replace the mobo. Yeah... like Fort Knox.

Thought that might be the case.
Bloody Samsung, that's so ridiculous!
Oh well, I haven't seen any other issues with it tripping so far. Warranty is already void anyway since it's water damaged and have had the screen replaced by others.
Thanks!
You're welcome.
Samsung Pay won't work either or maybe Secure Folder. Not the end of the world...

Yeah definitely not the end of the world. I use google pay over samsung, and have never used the secure folder (I use Onedrive Vault).
Are there any other negative effects apart from Samsung Pay, Secure Folder, etc.? I just read that on some older devices the battery life was decreased as well? It's a shame that it can't be undone... I mean, what harm does it do if the phone was rooted (or even attempted to be rooted... it didn't even work!) once. Why should it forever be unsafe from then on? I want to use the phone as stock as possible, original firmware, no root, ...

It's so you know the phone's security has been compromised. Rooting and custom roms makes troubleshooting much more difficult.
Can't blame them for not wanting to troubleshoot other people's firmware on top of their hardware.
Stock Samsung's are relatively easy to troubleshoot...

Yeah but knox stays tripped even if you reinstall the official firmware

Because the bootloader was compromised. A core component to Knox security.

help/info about samsung rooting

hello everyone,
I have and use android phones last 10+ years, always rooted. But I never had samsung phone.
Now I hear only half informations from my buddy, that its dangeous to root samsung because of knox (i dunno what knox even is).
So, now I'm thinking to buy S20 and want to root it, and my question is..:
If I root it, is anything ''broken'' on the phone ? Can phone still recieve official Samsung OTA updates?
What are minuses? what to look for? What about this "knox"?
Please need informaions
Well, I've owned a couple of Samsung devices over the years and I guess I can speak a bit from experience. Here's what you should know:
1.- U.S. phones have their bootloaders locked, so avoid buying a U.S. variant if you want to root it (some people want them for their Snapdragon chips)
2.- Knox is an e-fuse in the phone motherboard. Once you trip it by flashing custom software (root it), then that fuse will be tripped forever. You cannot get your Knox your status back to official unless you change the motherboard. Even flashing stock firmware will never get you this back to official.
3.- A lot of Samsung's security apps check for this fuse and will refuse to work if they detect that you've tripped it. Samsung Pay, Pass, Secure Folder are just some examples of features that will stop working when they detect a tripped Knox fuse. Some of these have bypass with root, but some don't.
4.- You will not get OTA updates with an unlocked bootloader, let alone root. It IS possible to get them back but only after flashing stock firmware and blocking the bootloader. These don't seem to check for Knox.
Understood, Thank You alot for informations and help!

Hiiii. I currently have a Samsung S20 and I have rooted it before. Once you root it Knox security will be tripped and you will not be able to get it back. This means you will lose access to apps like Samsung Pay, Samsung Pass and Samsung Health. You will not receive OTA updates if you're rooted, but if you flash stock firmware again and lock the bootloader you can start receiving updates again. I currently have a custom ROM installed and I have my ROM rooted. To me, it's been a great experience overall. I didn't really use the Knox features, so I didn't care much about losing it. I have loved rooting my S20 and using a custom ROM !!

Actually you can use Samsung Health, just currently no version above 6.19 (2 versions behind current) until we find a way to patch it...i use it daily with my Watch 4 on Rooted S20+ 5G....

Ohh okay !!! Thank you for letting us know !! I don't use Samsung Health so I had not tested it myself, but I had heard that Samsung Health doesn't work with root. Thanks for telling us it works fine !!
so, when rooted there are no OTAs.. thats a nono for me heh.. but question, if no OTAs come from mobile itself, is it possible to get uprades through PC then.. (Kies) maybe ?
