ROOT: is there a way of not tripping this Knox thing yet? - Samsung Galaxy S8+ Questions & Answers

Hi there,
I just got my brand new S8+. The reason I want to root it is to be able to install Cerberus as a system app, so if it ever gets stolen or lost, I'll be able to track it no matter what. However, I'm worried about this Knox thing. I heard that besides voiding my warranty and "tagging" my hardware, I'll also not be able to use Samsung Pay and some other apps. I wonder if there's currently a way of rooting it without tripping Knox. Maybe by using KingoRoot, towelroot or anything similar? Does any of that work?
What do you guys suggest me?
Thanks!

As of today, none such root exploitation successful.

I wouldn't worry too much about it. You are still able to track, lock, and wipe directly from google and samsung accounts ana there is always Plan B app in play store.

or buy a non-U.S. version phone, which work perfectly with U.S. companies (AT&T type GSM systems).

[Q] Samsung Galaxy S6

I’m looking at the galaxy s6 leaks and the phone sounds amazing. Take into account that I still have a droid charge and you see how excited I am to get this phone. Before I plunk down money I have to wait for it to be released. Between now and then, I need a few answers to some questions:
1. Root access – Will it be hard to root Android 5.0? I’m asking because I have all my apps and data backed up with titanium backup and want to be able to restore them to the new phone.
2. Flash – Ever since flash was officially dropped from the android realm, people have been supplying hacked versions that work with 4.X. Will this continue? I’m asking because the site I use to watch out of market football games still uses flash.
3. Keeping unlimited data – I have the unlimited data plan with Verizon and do not want to lose it. I was told by someone to buy the phone at full retail and I’d be able to keep it. I then read online about buying the phone through Best Buy and being able to backdoor keep my UDP. Someone then told me that Verizon could at any time switch me to tiered data if I do the BB backdoor thing. I’ve heard rumors that the phone will cost nearly a grand and I’m not to keen on paying that much, if I don’t have to.
What do y'all think?

There's root for android 5 but you can never know what Samsung will actually do to the S6, what my head says that it will probably be a way to root but that will trigger Knox....
Enjoy, Good Luck!
Btw I hate Verizon because they don't allow to unlock HTC bootloader.

What is Knox?
If I'm not initially able to root, how do I back up my apps and data to transfer them to the new phone?

Knox is a security measure that Samsung has put into their devices, it will also show up that your device was rooted (even if you'll reflash your stock rom)
You can back up your apps with google accounts but unfortunately you will lose your app data (like levels...)
data like pictures etc.. can be saved on a sd card, pc or there's some apps that will do that without root...
-It's almost midnight I might be slow!
So how do I get around Knox saying the phone is rooted. I'm asking because I once had to unroot my current phone to take it in for warranty replacement due to screen burn in. The joys of watching online video on an unlimited data plan
Also how do I transfer app data to my new phone without a program like titanium backup that requires root?

You can use Helium to backup your old phone. It does not require root, and you can backup all your apps and data.

Does knox mean that the phone can't be rooted? I have been using open garden tether with unlimited data plan and want to continue once I get S6.

No, you can root just fine.
In order to root Lollipop you must be able to unlock the bootloader. I don't think any of us know whether the S6 will have an unlockable bootloader or not. It may vary by carrier (here in the U.S.).
Assuming you can root the S6, be sure to make a nandroid backup before restore your apps and app data. The internals of 5.0 are VERY different than earlier versions, and restoring apps and data might (or might not) cause issues. In any case, be prepared to start over.
Reinstalling your apps from the Play Store is probably a safer approach.

That's all only related with one thing - exploits. So, it all depends on how many and how good(bad) of exploits on S6 firmware. No one could tell you now because the product doesn't exist yet. Since the security on Android become stronger, you can imagine that the time required to root the phone without tap knox will just take a longer time(Sony Z3/Z3c took them almost 4 months last time to root without void warranty) and it also depends by the sales of S6 and the community size on XDA, famous phone will get support first because of more developers.
You can use Dolphin broswer, it runs with owned ver of flash player, it built-in flash support so you don't need flash installed on system level.

[Q] Knox, root and "permanent"

Hi All,
I'm reading that root can trip knox, having never owned a Galaxy since the S2 I'm not overly familiar with knox but I've read about what it does.
What is bothering me here is that there seems to be a suggestion that once knox is tripped, that's it. There's no way to untrip it even when flashing a stock factory image again via odin?
Firstly, is this correct?
I'm worried about resale value to the point that I might not care about mobile payments etc, but others might, so a tripped knox could affect value.
If the above is correct I might cancel my pre order, I need root but I don't want a phone that's got limited resale either.

Yes that is correct. Once the Knox flag is tripped you can not reverse it.
I don't think it has been confirmed yet that Knox flag breaks Samsung Pay. From what I have read it breaks software dependant on Knox security, ie the BYOD type apps. They use it as an indicator your device is insecure, so It seems reasonable to assume Pay would break too.
Damn it, What a stupid thing to do.
I can understand it being tripped if you are rooted, but to make it permanent if the situation is reverted is ridiculous.
Thanks for the info, I'll hold out a few more days to see what develops just in case, but I think I'm going to cancel my preorder as I need root but I also have to consider selling it on eventually.
Stupid, stupid decision. :crying:

hey, why do you need rooting your phone?
I thought the same way but now I'm going to use adaway with setting up proxy settings in my wifi and mobile apn connections.
The only thing I should need root for is Titanium Backup, but I think with Helium (by ClockworkMod) backups should be performed easily

Its more than Adaway / Titanium backup, its removing Facebook, Instagram and Skype, which i don't use and or want, being able to run Xposed and root explorer so that i can use MY phone the way I want it without permanently affecting the resale value even if its returned to stock.
Look at it this way, I have a lovely PC for you - top of the line, fast as hell, lots of memory, premium price, but im going to install Windows 8 on there and a bunch of FREE apps , only im going prevent you from removing them, make sure you cant put Linux or Windows 7 or Windows 10 on there until i say so, prevent you from making any change to the Windows directory otherwise we'll stop you from buying things PERMANENTLY and void your warranty on the hardware so that you'll not be able to sell it on. EVEN IF you factory reset it with my software....
Its a shame as i REALLY wanted this phone, but it looks like it may not be for me unless something crops up with regard to KNOX and root.

I'm absolutly with you.
For me it's not a problem because I'm using Facebook, Instagram and Skype. Didn't recognized that they're preinstalled... sry^^
Of course I prefer using the phone the way I want, but it's not as important to me as loosing the warranty. Sure this is quite stupid that Samsung wants to tell us how to use their phone.
If mobile payment will still works with triggered Knox, I'll definetivly root my S6 Edge and maybe try to slim down the stock Rom like I did with my Eragon Rom for the HTC One M7

Yeah - its a shame - hopefully you can still use it, time will tell.
If root comes out without KNOX trigger i'll be all over this - might be too late for day 1 though - i suppose i'll just have to be patient and keep an eye on it.
In the mean time, i'll keep my preorder until the 5th or so then cancel unless something comes up - damn shame though - still i've got my HTC One m8 keeping me happy for now.
There hasn't been solution for KNOX for so long, that it's very hard to imagine that there will ever be one.
I hate KNOX so much, I don't think I will ever purchase another Samsung phone. This is not an absolute statement of course, however it is rather so.

If you have root couldn't xposed just hook that call and return KNOX=True whenever queried? I've seen something similar in the past to make Google wallet work with root and without the secure element it required.

The thing is, Knox isn't just going to be a Samsung thing, after all its a Samsung and Google collaboration and i believe and it will end up spreading. To be honest, i've no objection and it think its a good idea - HOWEVER
I do think the real problem here is that IF the phone is returned to stock it should reset the KNOX flag back to being unset. Simple, everyone is happy.
If i choose to root then fair enough, trip knox as the phone isn't as secure as it should be - i don't expect to have root access or Admin privileges on my work PC normally and if i try to work round it there are logs to indicate that.
However, i DO expect to have it on my OWN computer and without the threat of the hardware being handicapped should i wish to sell it on, that's just wrong.

The problem, from a security perspective, is that there is currently no way to ensure that a phone returned to stock is secure.
Samsung decided from that point to just say once the phone is compromised... that's it. Certain features of Knox disable and, if it's your carrier's policy, the warranty may be void.
But let's be honest from that point as well. Rooting, in most contracts and terms of use, voids the warranty anyhow.
I think many have taken that for granted and don't realize that it can't be in a secure environment.

Why? I don't see how a phone flashed with Odin using a ROM with a verified cryptographic signature cant be deemed secure? Check this - unset KNOX...
This is like saying that once i've installed Ubuntu on a "Windows" laptop it can no longer be deemed secure and while we are at it, lets fry a hardware fuse?
We are SOFTWARE rooting the phone here, not hardware hacking.
I'm actually curious as to the legality of it as well as they are disabling a part of your phone permanently and on purpose because i choose to run a different OS than the one supplied, but i'm no lawyer and there's probably a loophole or a law allowing it somewhere.

What you may be doing is granting software access to root and you may only use root to modify things at a software level.
But you have to keep in mind that's not the only thing root access can do.
It's perfectly legal and I'll even wager they're part of the DoD specification that both they and Apple want to sell to the government.
You have to consider it from a worst case scenario. If a device has been modified in any way, how can they assure it's been reset 100% completely back to stock... both at a hardware, firmware and software level?
Without physically inspecting the phone, they can't - which is why I think this is the way it is.
The Knox team put out a blog entry a while ago about this topic, noting it's a good balance between ensuring security and allowing non-business users to root the device if they want to.
One other note: I don't know enough about the Exynos devices past N2 to say if they've fixed it... but the Note 2's Knox flag was not an e-fuse and could be reset.

Hmm..
Keep in mind here i'm not suggesting apps requiring KNOX are made available whilst rooted like Samsung pay etc, only that the KNOX bit is reset if the phone is flashed back to factory defaults using Samsungs own Odin program and a cryptographically signed firmware. If at that point the phone is rooted again, it would expect it to re-trip KNOX just like it did the first time.
But, lets play a game, lets say i gain root, KNOX bit set and i cant use KNOX apps. I then use that root to make modifications to firmware on the device somehow, which is what i think your insinuating above, not necessarily the Android System partition, maybe the modem firmware (even though its closed source) or something else, for whatever purpose.
IF you have that level of knowledge of the phones hardware then i don't think it would be too much of a stretch to suggest masking the KNOX bit as set would be too hard either, maybe by intercepting the system call to check its status etc but even then when you say:-
"If a device has been modified in any way, how can they assure it's been reset 100% completely back to stock, both at a hardware, firmware and software level"
The firmware and software is taken care of by Odin, that does both, say we did modify the modem firmware above, Odin would write right over it with a VERIFIED image wouldn't it?
Whether you have root or not, you cant do anything about somebody hardware hacking, that's a whole different ball game, if you hacked the hardware you could just change to always respond as the KNOX bit not being set but that would be low level stuff way beyond what pretty much anyone here could do.
Would be interested in that blog post if you have a link - I just don't see this as anything more than a way to discourage more people from rooting.

There are many, many more on the site, just use the search keyword root.
But that's the gist of it - they understand that some may want root for simpler reasons.
Others may want it for more nefarious ways, like trying to access the keys within the TPM.
The end result sucks for consumers; but as a IT admin I can tell you I wouldn't trust a device with sensitive corporate data if it has been rooted... ever.
Thanks very much, I'll take a look when I get a chance later.
Anyone have an idea which carriers enforce the Knox tripping for repair?
Although this looks like a great device, if the Knox trip invalidates warranty, you may be very angry if lets say the usb port or power button malfunctions and repair is not covered.
Might as well buy a Note 4 exynos since apparently warranty is not valid in usa.

Technically the US has a law, the Magnuson-Moss Warranty Act, which should limit manufacturers voiding of warranties to that damage which can reasonably be blamed on the consumer. (for example, rooting your device shouldn't void the warranty for a defective power button) However, manufacturers usually claim the opposite here and I'm not aware of successful legal challenges.
Looks like sprint at least is ok with it

I agree. My last Samsung was a note 2 which knox wasn't a factor and not a big push then. I didn't got to any Samsung's after that due to knox.
I just want root for the reason's you do and edit the phone's density.
Its a shame that we cannot just flash back to stock and "close things up" per say if we want to sell it or have a non root related warranty issue.
Knox is mainly geared toward the business side , so why not make Knox activated by a Admin when the phone is to be used for business where the security is needed. And leave it un-activated for the rest of us.
And i would think the ratio of people rooting vs people not rooting (nor even knowing what it is) is so slim that allowing it wouldn't cause a pandemic in warranty claims.
I know before i root anything i make sure all my points are covered and there are processes in place to un-brick a device. Which i haven't had to unbrick a device since my Moto X or OG Droid.

Getting a Galaxy S7 Today - Does Rooting Trigger Warranty? And a few other questions

Hi Everyone,
I remember back when I had the Note 2. You could reset the counter that gets triggered in Download Mode. Does the Galaxy S7 have a similar counter once I root the phone and install custom ROMS? And is there a way to reset it?
I'm getting the SM-G930F from my brother today. And I'm looking forward to it, but rooting the phone & using Xposed Framework & AdAway are priorities for me on any phone. It has two years warranty, so if anything happens to the phone I want to be able to return it.
Also after 1 year I can upgrade the phone to whatever I want on his plan, so I'll likely get the Galaxy S8. Would be great if someone can answer me today before I root it.
I'm going to use CF Autoroot, then install the latest TWRP. Do a full backup using TWRP. Copy that to the PC, before I start experimenting with different ROMS & mods.
Also another quick question, why do I not see any Android 7 stock Android ROMS or CM based ROMS around? That's surprising. Are the developers waiting for Google to release the source code? When is that expected?
Thanks in advance for all the replies.

Installing other custom ROM will trigger know and you will lose warranty. I don't see any reason to install custom ROM at least at the moment. There is a root method that claims to not trigger knox but I haven't tried it.
Sent from my SM-G930F using Tapatalk
Try the root method that people relate that doesn't trigger knox..
And there's a few roms to nougat, no custom kernel for now.
Enviado do meu SM-G930F através de Tapatalk
Any root method for the G930F will trip KNOX and void warranty (Afaik it is other models that can be rooted without tripping, unless I've missed something lately)
Flashing anything custom will also trip KNOX
There is no way to reset the KNOX counter
If you trip it, that is permanent
If knox is tripped, will they also refuse to do any hardware repairs? For example, after 2 months my home button doesn't work anymore.

All, warranty is warranty, it will be refused
In some cases people get lucky and Samsung repair anyway, maybe because they didn't check, but if KNOX is tripped, all repairs will cost you money with no warranty

In Europe, Samsung has to repair the equipment even with Knox tripped, as long as it was not root that damaged the hardware.
I had to send my phone to Samsung, because i screwed up the phone with Xposed and Samsung repaired it without charging anything.

Oops, looks like i got lucky.
Will not try and root again so soon.
Alright, so I've done some research on this subject.
Most root or ROMs will "Fry the knox circuit." Basically, what that is, is a secure, totally private fuse that your phone has, which is like 2 nanometers small chip in you phone's mother board. It's an absolutely tiny fuse that protects the ADMIN section of you phone. Currently most, if all known methods, of root will trip it. So, as stupid as it sounds, I'd say "Buy a USB killer." Which is a USB device meant to test protection circuits. And if you phone is already dead to some point, if they can't power it up, they may just say "**** it" and do a warranty replacement.
Otherwise, unless they can tell, they'll just swap it for a preowned model if they can't tell you ****ed with it.
Honestly, if you have insurance on it, smash it with a hammer. If not, say it started smoking while charging and make sure it won't charge, Apple is scared ****less towards possible fire damage and samsung just had that Note 7 thing

Knox recover possible?

I'm just curious to know whether or not it's possible to restore from a KNOX trip after installing TWRP and a custom Rom. Does restoring stock Rom via Odin restore KNOX status to x0?
No. Once it's done it's done. It's a hardware fuse that blows. You can't undo that.....
Thanks for taking the time to reply. Damn that sucks. So if i trip KNOX and go back to stock Rom via Odin, will I experience tripped KNOX related errors and popups? Would Samsung Pay still be functional?

No Samsung Pay, S Health, Secure Folder, and everything that is knox related.
I just got mine in the mail. Literally 3 minutes ago. SM-G955FD.
So aster rooting I'm definitely going to see Samsung Pay related errors and if i were to attempt to resell, those errors would be dead giveaway. Correct?
I'm debating whether or not to root and put custom Rom on it.

Most definitely
The phone will be missing all those features stated above and also no warranty
Will majorly affect resale price
Not really fair to resell without stating the issues from rooting
So I guess that settles it. Not going to root. That sucks. How is Samsung getting away with this ****? Apple-like behavior. I'll miss rooting; custom roms etc.
Thats whay i will sale my s8+. Thats bored whithout custom roms.
I will back to Note 5, S7 Edge. I think the "new" note 7 will come whith the same problem like the s8. Fu()/&= KNOX !
It's Samsung's loss, modding community will move away from Samsung devices if they continue this lock down crap. I got an international variant so I can root. I don't really care about Samsung pay, S health and secure folder are nice so that sucks but there are likely alternatives in the play store.

You're absolutely right. I've already started looking as other devices, the only caveat is the specs -- the hardware. They're not up to par with Samsung's technology. I hope I'm wrong about this. If i am and there are other devices that are just as good or even better, I'll jump ship.
so u cant use S health in a rooted device? like heart rate monitor and running stress test? etc?
You can use those on a rooted device by hiding root. If you go back to stock, those will not work.
Well now this is confusing me a bit. There's rooting and there's installing custom recovery. Which of the two is going to trip Knox?

Both; you need to install a custom recovery to root.

AFAIK, S Health is the only one of the knox-related apps that can work on a rooted device. Check out this post for instructions.

I'm waiting for that mothership.:crying:
Samsung had locked devices since at least the S6 using Knox. Still one of the highest selling phones out there so I doubt they will care about a few losses in sales. Provably make up more I sales gained by corporate clients.

Lets be clear here, warranty is only lost in some countries, not all. In the EU its not, even if Samsung claim it is. You should be getting the seller to deal with any warranty claim anyway, not Samsung directly.
As for it being Samsungs loss, well the modding community is absolutely tiny, far less than 1% of sales, so they really dont care and lose nothing. Its a small price to pay for the potential security issues a hacked Knox can bring, for example.. Its possible to simulate knox, or 'secure folder' on a device, but in reality the phone is sending back all the information in that folder to a third party server. However to do this you have to root and flash custom software, this trips the real knox, which the device will then complain about. Tripping Knox has to be permanent otherwise it can be bypassed.

1% is an over statement.
0.01% is probably still overkill.
Far less than 1%... Well, for giant company like Samsung is, thats lot of money.. But... where is Knox exactly located on motherboard? Can be regain by erasing all (nand erase all, efs, etc) and than flashing all partitions through BOX-Octopus Box and dongle????

No. Rooting has literally nothing to do with the knox counter. Knox is protection against untrusted code.
Every single snapdragon s8 s8+ and n8 of rooted with a 0x0 counter, so it's a little more than possible

Should I root (opinions)

Hi I've been rooting phones for over 10 years now but the past couple of devices I haven't due to it tripping knox etc but I miss a few things with root and looking for peoples opinions
I love having adaway and been able to fully uninstall apps I don't use
Is there much of an improvement on battery life as I have the exynos version :crying:
Also an app i haven't had chance to use is viper4android is it as good as people say and does it actually boot volume on bluetooth audio without distorting etc as that would be my main use for it
Also what exactly does tripping know destroy? I've read it affects Samsung pay and Samsung pass is there anything else
And has anyone had problems selling there device afterwards from tripping know (mainly in the uk) as I change devices quite a bit and sell them on lol
Thanks
You can use adguard if you don't want to root. I haven't bothered rooting anything for a few years now. It doesn't deliver any additional must have features i can't live without, unlike it used to.
Same boat, rooting for decades. Yet it seems a bit too immature this time on this device.
Also got the exynos junk (Iknew before getting it, but free phone from work).
I decided to go without for now.
Same here - decided to go on without root. The features I miss are - firewall (need to try knox firewall though), direct time sync (minor), some console commands to manage files, titanium backup - this is a major issue, so I can't backup OTP apps etc.
Don't root your device since that requires you unlocking bootloader to root and doing that triggers knock safety thing so it destroys knox permanently and then apps such as Samsung pay, samsung pass, secret folder, encryption and few more that requires knox to work will be unavailable, since knox chip is no longer functioning. Also warranty would be voided if you got 2 years warranty.
So if you plan to use samsung pay or any of other apps later on then avoid rooting and touching bootloader.

i dont know about usa and other countries, but in europe ur warranty won't be void if knox is tripped (afaik)
Still can't do without root unless there a way to block ads while using a vpn of my choice and control a firewall. Have my Note two days now after waiting 3 weeks for it to ship from Hong Kong and first thing I did was to root.

Well actually to get it tripped requires bootloader unlock for root and that would void your warranty in Europe. So id knox says 0x0 it also voids warranty
Only those that care about Samsung's proprietary Knox and it's associated bloat should worry about knox being tripped. Only thing I'd probably care about is 3rd party banking apps that might not work with patch hide. If that still works or not unsure.
rooting my n9860 asap. finally just got the oem option to show up. last phone i had was a note 8 not unlockable...and had to keep it for too long, wanting root the entire time. so i'm not missing the chance to do it now. why? to try custom rom, get all bloats/google/samsung apps off the phone and stop looking at system settings that i cannot change(top reason), learn about android / do some dev on it, test root apps made by community(2nd best reason), get a recovery installed, nethunter, call recording, toolbox, run my fav firewall. probably more reasons that im not thinking about right now

im considering rooting my N9810, but im wondering if I will still receive OTA updates then? or do i have to manually flash the update with each ota?

You wont get OTA after rooting, since rooting requires you to unlock bootloader so then OTA won't work. Also KNOX won't function permanently once this is done too.
So think if you going to use samsung apps like samsung pay and such then avoid touching bootloader and rooting.

I doubt it but I never tried it before tbh. I guess i should say that i might not be a good example to follow when it comes to updates. i almost never do them. because it always was a compromise one have to make if wanting to root. at least from my experience. like, keep your firmware version low or you loose the ability to root. but gain security patches. i chose my side of the fence long ago hehe
