I asked in one of the root threads and didn't get a reply. From looking through the existing threads I understand that you lose samsung pay and the hidden folder feature. I can live with those but is there any other features lost when unlocking the bootloader?
1.) Once knox is tripped will features be lost forever or start working again once tablet is returned to stock?
2.) Still shows as widevine L1? Any loss in resolution from an streaming apps (youtube, netflix, amazon prime, youtube tv)?
3.) Any other apps or features not working?
1. I rooted my Note 4 phone and Note Pro 12.2 tablet some years ago. Back then, I did this installing a custom recovery called TWRP. This blows an e-fuse on the main board, which prohibits Knox from working forever. Flashing back to stock recovery can't "unblow" a fuse.
2. Not sure about this one, sorry.
3. In my experience, rooting broke only those apps that relied on Knox. But I suppose these days more apps are likely to detect if they're running on a rooted device and refuse to run. That would account for the popularity of tools like Magisk that try to hide the root state from apps.
After I moved away from those devices (S7 Edge and Tab S3 were next in my history), I abandoned the rooting game. Not sure the value is worth the cost anymore.
EDIT: There are apparently ways to root without flashing a custom recovery -- this was news to me, and shows how long I've not been playing the rooting game, heh.

Thanks for the reply. Yeah I have rooted my samsung devices in the past as well but I believe the last one I did was my note 4 as well but I don't remember widevine being a thing back then or at least I didn't care. Of all the features I am concerned about that. Don't really care about the other samsung features save for maybe dex but I don't think that is affected. Can anyone rooted confirm if they still have widevine? Is any legit premium video app like netflix or youtube tv affected? My oneplus 7 pro had widevine downgraded I believe when the bootloader unlocked which was annoying.

That's not quite true these days.
Using Magisk to root doesn't "blow the e fuse".
Rooting without installing TWRP will keep the warranty status 0x0 which is valid.
BTW: Netflix ect. Works just fine.
It's nice to see old Note 4 guyz around. I was very active in the sprint Note 4 forums years ago. IMO that was the very best phone samsung ever made. @tx_dbs_tx was a mad man of a developer for that device.

Confirmed that unlocking the boot loader and rooting with modified firmware does trip Knox. Magisk can try to conceal this bypass some security checks, but not always successfully.

100% agree. Once upon a time a Galaxy Note was not just a Galaxy S with a stylus. Alas, it appears Samsung is diligently heading away from what made the Note a distinctive device.

I thought the knox tripped when you unlock the bootloader, don't you need to do this even if you root your device without installing twrp?

Yes you do need to unlock the bootloader to root your device... But that doesn't trip knox.
Rooting with magisk will definitely trip knox, even without TWRP.

Did you see the picture in the post that was quoted?
It shows as rooted and knox efuse intact. So the warranty would still be good as long as it doesn't trip the efuse.
Look at the picture before telling me a generic answer. I already know that when the excuse is blown the warranty is lost. How do they have root without tripping the efuse?
This is the picture I am referring to.

unlpcking bootloader alone doesnt trip knox but as soon as u flash any custom firmware i.e. disabled vbmeta, twrp, magisk etc. then it will trip knox.
theres thousands of threads on xda alone about tripped knox and what works n doesnt work so id go n look for urself before anything..
and usually it will break ota updates but can depend on device etc. but ull likely have to update via odin

Just got two T-Mobile Note 3's and want to root them as I did our Verizon Note 2's.
Was watching the XDA video on using the chainfire method (which I used to root my Note
tablet) and it looks like the way to go.
That video came out in Oct of 2013. The little owners manual thingie that came
with the phones states that any "If unauthorized firmware is placed on the device it will not
work."
Question: Does anyone know if Samsung has buggered up the phone since October
so that the root no longer works, or am I still good to go?
Thanks!

You can root a couple different ways. It depends on if you want to trip Knox or not.
I literally just used chainfires auto-root via Odin and it worked fine

Thanks for the response, but I'll admit to being enough of a newbie not to know what you mean by trip Knox?
Knox is new Samsung secure environment, if you start flashing ROMS etc it will trip Knox flag which no one knows how to reset, if it ever can be reset. Samsung can and did refuse any warranty repairs if the Knox flag is tripped. As far as rooting goes if your firmware is below MJ7 I think, you won't trip the flag, if it's MJ7 and above the flag will be tripped I think. For example I have MI7 (last 3 digits of FW build) so I can root, without setting flag. Anyhow, I would suggest you read and learn as much as you can here, before you do something you can't undo.
I really wanted to wait until the 4.4.2 Kitkat update before I root.... but I can't wait.
I think I will cave in and get root this weekend!
My understanding is that the retail verizon wireless edition (non-DE) of this phone can still be rooted. But you will trip knox, thus voiding warranty. I also understand you don't have an unlocked bootloader either.
I don't care about warranty, but I do want root. My question then becomes about future updates. If knox is tripped, can I still get to lollipop when it is released. I know I would probably loose root again at that point, but I live in the hope that eventually that too will get rooted (I know it may be vain hope, but still).
If my phone is rooted, will it block me from ever getting lollipop? Because without a bootloader, I can't put lollipop on through a custom rom either.
So, for someone who absolutely doesn't care about warranty issues, is root still a bad idea?
Thanks

Nothing yet. It's a nice phone but if you need root go for the DE edition. I can live without root, it would be nice but it's not a big deal to me. I have other rooted phones I can mess with if I want.

Unlike the Samsung Products, Asus doesn't have anything like KNOX to keep track of how many times you do something to your phone. If that was the case my phone would have a flash count of 100+ :laugh: because Im always pushing my phone to be better and faster then what come on it stock.

Rooting doesn't require bootloader unlock BUT custom recovery/rom does...
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.

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.

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.

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 !!
