Hello guys. Recently i joined note 8 forums from note 3.
I have 950f with dual sim. I can choose to oem unlock. But i have galaxy care and guarantee of the phone. I want to root to add apps for camera modding and etc. So I'm afraid of rooting to change the agreenment of care and other stuff. If i root i change the agreenment?
yes
Instantly voids your warranty. I mean don't you already know that? Just saying.
If afraid of rooting, DO NOT DO IT, and about warranty, depends of your contry/carrier polocies, in Mexico rooting does not void warranty at least claiming it with the biggest carrier telcel
rooting will also void usage of Samsung Pay.
It will trip Knox and you'll lose secure folder forever too
There is no compelling reason to root today. From themes to ad blocking, there is a solid non-root solution available. The reasons to avoid root like warranty and Samsung Pay are pretty big. IMO, stay away from root. Your money tho.
Yes you can. Root and enjoy

That's bad advice since OP is worried about voiding warranty and losing functionality...read post 1.
If you have any bit of desire to maintain warranty coverage you just simply stay away from the topic of rooting. End of. Any stink of warranty stuff, rooting is a no go.
When you root, you trip the knox counter, there is no way back, even if you unroot and return fully stock. The knox counter stays tripped which means you'll lose Samsung Pay and Secure Folder forever.
You gain features and functionality with root, however. Native automatic call recording, ad-blocking (not just in the browsers), Titanium Backup, Full system Backup, AFWall+ (blocking internet access to specific apps)... etc.
So it is up to you to decide whether it is worth it or not.

Here's what I've been able to gather sofar.
You cannot root without tripping knox
You cannot undo a knox trip
No knox means no Samsung Pay
Knox rhymes with Knocks
Tripping knox voids warranty...
Is there anything else i need to know? how many apps and features depend on knox?
I'd rather not trip it, but its been 3 weeks and the lack of certain root privileges is killing me. Being my 1st Samsung device, I'd like to know fully what the consequences are of tripping knox for the sake of convenience.

As of right now losing samsung pay is the only downside unless it is a corporate phone. In the past you could trip knox and still jump from it but now that samsung pay is connected to knox I would bet that will change.

By "unless it is a corporate phone" do you mean tripping KNOX will disable encrypted enterprise apps like GOOD Mobile? Curious about this.

Honestly I'm not sure but I'm sure someone on this forum can give us specifics.
I could stand to lose Samsung pay as I intend to sell this phone for a Note 5, and Samsung Pay wont even begin to roll out until much later.
I've ned tried it, but can you lock TWRP?
I just want a quick answer as I keep finding people claiming to be able to root t-mobile s6 sm-g920t ver. 5.1.1. I cannot find anything to support this without a lot of headaches, much less being able to find and download needed files for root.
Can I successfully root this Samsung Galaxy s6 SM-G920t?
Or should I go back to my HTC phone?
Thanks,

FYI: I got this phone yesterday as a promotional and did not have to pay for it. I have always strayed away from Samsung because of all the hassles involved in rooting any Samsung device over the course of the last 10 years or maybe a little less. As soon as I signed in to my Google account the damned phone automatically updated. "Thanks for the options Samsung!!! I didn't have any choice but to go through with the update.
Yes, you can root it easily but you will void your warranty by tripping Knox.

I am not worried about warranties. I root all of my android devices. I pay the phone companies a lot of money every month. I usually buy all my devices straight out too. So Samsung can do what they need to, as long as they stay out of my way, I will stay out of their way. Anyway, my other main concern is all the calling problems and the finger print phone lock. Will these break regardless?
Thanks for the fast reply, too!

The only downside to rooting the latest firmware versions is you cannot use Samsung Pay with Knox tripped. Other than that, I haven't experienced calling problems or any issues with the fingerprint reader. Haven't heard of call problems as a result of rooting but the fingerprint sensor not working was a result of using the engineering bootloader (to maintain Knox warranty status) on a previous firmware release.
Hi all.
I'm asking this question because a friend of mine told me that he knows someone who could crack and unlock pretty much any phone's anything, for a price.
Just the other day, my friend took back his phone from another person (why he took it back is another story) who had been using that phone of his. So obviously before my friend could use it he'd need to factory-reset it. But at the last step the phone asked him for the email password of the previous user, the person he took the phone back from. Instead of contacting that person, he sent his phone to the... well, hacker. Then the next day he went to take it back and it was unlocked already! He paid about 40 dollars for it.
How?!
He also told me the hacker could even crack or bypass iPhone X's lock screen, but that would cost about 500 dollars. For Note 8's lock screen, he said he could do it with his eyes closed.
So what is all this?? Is all this possible?
And Knox? Is there really some way to crack Knox?
Please enlighten me. Thank you.
About knox, there is no way to reset it once tripped, because it is a fuse, (an e-fuse), I know
that cracking the lock screen can be done, but it involves resetting the phone
The topic question is about NOT tripping Knox while cracking it. Whether there is such a way, or tool. Because I was told by someone that someone else could do it.
Cracking the lock screen can be done but involves resetting phone? Reset how?
Love stories when it's pertaining to someone knew someone that could or did something. My neighbors friends daughters step dad's uncle Ron, reckons he can hack any phone including bypassing Knox.

I'm not saying I believe it. That's why I'm asking here. I wouldn't have if I believed. At least explain how he cracked the FRP.
So I'm taking your response as "no, Knox can't be hacked".
Next person.
Knox is made as it is for this exactly purpose, you can get through it, yes, but leaves the trace 0x1, which means someone tampered with it, so the owner(individuals or corporations) can know for sure it has been compromised, and take the adecuate meassures about it, as for unlocking a device without the propper passwords or biometrics, that is something that can be done, but nobody even knowing how-to do it, will teach you how to do it here, as it could provide a way for potentially illegal practices, and try not to be so adammant in yor post
Lol and I'm not even asking to be taught how to do it. I'm only asking to know whether there is or isn't such a way (or ways). That would already be satisfying. Because right now something that I trust a lot (Knox) is, apparently, crackable. I of course wouldn't believe what I was told so easily, and so I'm here.
What I'm saying is that I understand pretty well how Knox works, and I know what I'm looking for. I'm just here requesting input from anyone who might know a bit about this topic, and I thank anyone who responds.
Well, you got the answer, no, there is no way to crack it without showing 0x1, that's it
Yes, I want to believe "no" as well. And that's what I'd believe for now. I also personally do not think it's possible. But considering it was coming from someone who cracked the FRP....... That was what made me to make the effort to start this thread.
OP, you've raised a few different issues here...password unlocking and Knox...
Knox can't be reversed once tripped, period. Fuse-based or something similar to that anyways, no way to undo that.
Breaking lockscreen passwords in another matter entirely...I'm sure you could Google that but I don't think it's appropriate for discussion here.

I understand tripped Knox can't be reversed. I know. And if a hack attempt trips it, then the hack has failed. But my question here is whether it's at all possible (even theoretically) to crack Knox without tripping it.
Yes. Lockscreen can be bypassed or broken. But what about FRP? My friend's phone's FRP has just been broken. Hmm...
Discussions about knox have been around in xda for years, no, there is no way around it, never have been, I doubt there will ever be, as it would render samsung pay as not trustworthy, that is why tje e-fuse is a physical security flag

Ok I understand now... Anything is possible in theory I suppose, but if anyone ever cracked enterprise-grade security like Knox it would essentially render it useless for all (because it could no longer be considered secure). Samsung has millions of dollars, if not more, riding on preventing exactly that. No one has cracked it yet, and it has only become more secure over time...so I doubt they ever will.

Thanks. The ways both of you put it make lots of sense. I'm regaining my confidence. After all, Knox is something that has gained the approval of many governments and organizations around the world and is declared fit for government work.
Then again, I learned that the Snapdragon Note 8 could be rooted without tripping Knox right? (Is this still the case?) Does this mean anything in terms of Knox security? (Mine is an Exynos by the way, and AFAIK Exynos Note 8 doesn't have this issue.)
Lastly, well... this concern isn't exclusive to Knox because any security system may have yet-to-be-discovered potential exploitable flaws, but Knox also has its share of flaws in the past, such as http://www.wired.co.uk/article/samsung-knox-security-vulnerabilities. I guess we can't really do anything about this individually.

Most of the Note 8 Snapdragon variants have a locked bootloader, so the root method is different there and do not affect Knox as far as I know. Other differences though, like not being able to charge past 80%, etc. Exynos bootloaders are not locked and use the standard root methods.
Hello all i think i have managed to turn off the samsung secure boot. i can write to the recovery without blowing the bootloader fuse i tried write the s8 snapdragon twrp to my recovery in past always just getting secure boot fuse blown resulting in having to odin
---------- Post added at 03:07 AM ---------- Previous post was at 03:04 AM ----------
back to samfail v3. Somehow this time all i get is a screen saying please take phone to att authorized retailer we knoticed you have unauthorized software on recovery. I reboot phone boots back into the pre rooted stock rom samfail v3. My knox is not tripped i also can do full back up and restore on flashfire pro no problems all partitions i was to afraid do bootloader partitions but can all the other protected ones modem efs ect. Am i losing my mind or is something going on here i have the full backups 6 gig worth saved so if so maybe someone more qualified can look at it.
Cash that i odin it back samfail v3 if only that easy
Just throwing in my 2 cents...
I believe there is a hack whereby the kernel is replaced when rooted. This will show that KNOX Warranty void is 0x0...
In reality KNOX has been triggered and Samsung pay won't work but the bootloader screen does say that KNOX hasn't been tampered with. Flashing a stock rom with ODIIN will reveal this trick however...

What I meant was if rooting could be done undetected by Knox, essentially does that mean Knox has... failed?

One of Knox's primary jobs is to monitor and protect the kernel, no?
I guess if in reality Knox has still been tripped then Knox has done its job...
No I have a Knox checker it says Knox is valid and see linux is in permissive. I'm on a att n950U but my stock recovery is for a n950X but I can load it and be rooted . I assume all v3 samfails are same.
I've always been into tinkering and love the idea of rooting but as a person who abides by warranties (or atleast mask it so the warranty is still valid) I've never really been able to do this being an ex-Samsung owner. The thought of tripping the Knox flag was a little worry of mine and as a result, i never rooted/flashed my S8.
I've since switched to the Mate 20 Pro and wanted to know if Huawei have a similar flag to the Knox flag, in which, if tripped allows customer services to know and effectively invalidate your device's warranty. I'm excited to potentially flash/root finally but I'm wanting to check this out beforehand.
I don't think there is a viable root option for this phone. Funky Huawei has an expensive root service where they root your phone using your computer and remote viewer--but the phone loses root as soon as an OTA is flashed and if you want to be rooted you have to pay full price and go through the whole process again.
This is not an attractive option, obviously, and if Funky Huawei could find a permanent root solution (which they have been trying to figure out since the M20P launch) they would sell that instead because it would be a much more popular and lucrative service.
I haven't heard of a knox like flag that gets tripped on any Huawei devices if you unlock the bootloader so you are probably safe on that front... at least for now.
Hello XDA developers and and users,
I just signed up and this is my first post.
Anyway I was wondering if I can root my S21 Ultra without voiding warranty and losing knox.... just in case I wanted to uninstall root and still have my warranty and knox services.
Sorry for too many tags.
Welcome to XDA
There's that pesky little efuse that protects Knox's integrity... once blown the mobo or that chipset needs to be replaced.
Sammy will do it for $400 apparently, according to one member here who did what you're thinking of doing. Get to know it a bit first...

One member recently had their display die and Samsung did replace it but charged them for a new mobo because of the blown efuse.
Samsung is pretty much silently admitting there's a display issue on some of these units.
If the 3rd party firmware fried the display he lucked out because the display was from a known bad batch. Samsung can only determine this many times by direct inspection, not remotely.
Samsung usually doesn't do warranty repairs on rooted phones, right?
Interesting, isn't it? It doesn't give you a warm cozy feeling though about Samsung though

The problem being the phone was rooted. Better have deep pockets if you want to root a new flagship Samsung device.
Basically Samsung returned it to factory specs and charged to repair the "damage" caused by rooting.

Knox services and factory warranty aren't the only casualties when you root a Galaxy device. Also it depends on how you root a device, that's assuming your device can even be BL unlocked. Many users end up with a very expensive paper weight as bricking the phone isn't uncommon. You'll lose Secure Folder, Samsung Pay, Health. OTA Updates can be restored if you flash the original FW via Odin. A number of apps can also be made unusable after root. I would weight these considerations beforehand as there are a number of apps which will customize your device without tripping the BL.

The potential to brick the phone should weigh heavily in one's decision to root especially on a expensive flagship device.
Just read all the " Help!!! I bricked my device" threads posted here. Lots of pretty paperweights...
Losing the factory warranty on the display and mobo are a big deal. Both are expensive and hard to repair.
OTA updates break phones too
It's the first apk I package block.
Those other apks I never use but each person is different and if your needs change... you don't want to find yourself painted in a corner with paint that never dries.
The stock Samsungs can generally be configured to run very well without rooting. More than one way to skin this cat...

You're out of luck then because you can't revert knox. I just did it through Samsung credit and they don't seem to care but the warranty is still void either way if it's rooted.

Doesn't matter if you unroot later. Once you root and trip the Knox flag, it is irreversible. It's not a software flag, it's a hardware flag called an e-fuse. Once blown, it stays blown. Whatever you do with the phone after that to restore back to stock, it will stay voided. Knox related stuff will never work again unless you change your motherboard.
I think it is possible

All the elaboration you need has already been said. If you want more assurance that this is not possible do a search for reset knox and see for yourself. This is just one thread of many and it was started in 2013... not trying to be a jerk but this horse is dead.
