Hey guys,
I've read lots of articles about Knox and the whole eFuse thing but the more I read the more unsure I get about rooting my S4 mini. Because of this and because I think you don't get any S4s without "activated" Knox Bootloader anymore I thought it would be helpful for all S4 mini owners (and maybe all Knox device owners in general) to list all downsides and also rumors about "blowing the eFuse" to hopefully take away some of the fears.
I think it's already clear that you could loose your warranty if you got a 0x1 flag. Which doesn't seem to affect EU people But anyway, I'd rather like to get a list of all the irreversible consequences with your device itself when rooting etc:
:: EDITED & ADDED SOME QUESTIONS ::
The answers in green = positive or red = negative show the current state according to the replies in here, If you have other experiences please let us know.
[ROOTING tripping KNOX 0x1]
Are there any irreversible malfunctions when rooting your device (especially the GT-I9195) and turning to "knox warranty void 0x1"?
Are all (pre-installed) apps - except the Knox apps - still working as they should on rooted stock roms (s-apps, cam, calendar,..)?
[GOING BACK TO DEFAULT FACTORY STATUS]
Regarding the software only:
can you go back to 100% factory status (unrooted, stock etc) with a "Knox Warranty Void 0x1?
- Yes, according to iPAQS4 you can go back with no malfunctions
Do you get the Knox warnings again?
No, according to iPAQS4
Are there any other app or system malfunctions?
- No
Is it true that OTA updates won't work anymore once you tripped your knox flag?
- No, according to iPAQS4 they still work
Is it possible to get official updates via Kies / USB cable still?
- Yes, according to iPAQS4
[FAILURES ROOTING, KNOX]
Regarding the Knox environment only, not self-caused rooting failures:
can there else go anything wrong that can't be undone like breaking important hardware?
or is there a higher chance to brick your device with Knox than without?
is an intact eFuse required by some other hardware (NFC, etc)?
Are there any other known problems/downsides?
Here is an interesting article about all myths & truths about Knox. It's very informative and also answers a few of my questions: http://androidforums.com/boost-mobi...t/807188-guide-q-myths-truths-about-knox.html

Can you go back to stock Rom (un-rooted) with a "Knox Warranty Void 0x1"? And with which problems do you have to deal (software warnings, malfunctions...)?
Can you still get official Samsung updates via Kies or over unofficial channels?
Are there any known hardware or software malfunctions because of the broken eFuse?
Are there any other known problems/downsides?
@ all_experienced_owners: would you still recommend rooting a Knox device or breaking the eFuse?

If you flash stock ROM (XXUBML1 for example) via Odin, the System Status will turn back to Official but of course the Knox flag remains 0x1.
Kies will also recognize your phone.
I don't know whether Kies/OTA updates will work, I never used/saw them.
If you don't care about warranty I recommend rooting

According to other posts OTA updates won't work anymore, unfortunately. Does anyone else know if updates via Kies/ USB cable will still work?
Have there been any Knox warnings when going back to stock again? It always says to disable all Knox apps once you have rooted your phone but back on un-rooted stock this is not possible, I guess?! So I think you will get these warnings again, don't you?

Sounds great, so you can always go back to original phone status (except your Bootloader and the OTA updates)? Just to make sure: you tripped Knox warranty void to 0x1, right?
What about rooted status (stock rom), did you notice any malfunctions with any apps, especially the s-apps?
Which rooting method did you use?
Thx

Not if you're in the EU. Under legislation, companies aren't allowed to void a warranty because of a software change etc (eg if a piece of hardware fails, they can't turn around and say you rooted your phone so you're not covered).

I unrooted my phone by flashing it with the original firmware with odin and than wipe data/ factory reset in recovery mode.
After that my phone had a ota from MJ7 to ML4.
If you recently bought the phone, I don't recommend rooting (although I rooted the phone the same day I bought it) If you really don't care about the warranty and the OTA updates, root your phone. I literally can do nothing without root.
As we heard today, our S4 Mini will update to 4.4.2 so I don't recommend rooting until it is out so you cqn get the OTA update.
Press THANKS if I helped!

Thx, yes that makes sense. I've also read a few articles about the warranty facts and always wondered why sellers can refuse warranty just because of the "wrong" software. I mean I never heard of anything like that with personal computers, notebooks etc. Would be very interesting, though if a mainboard manufacturer doesn't give warranty and claims that Windows, OSX, Linux etc destroyed it because you used it as an Admin . So actually I think, this regulation should apply world wide not only in the EU.
But we should keep in mind that warranty is not the same as guaranty which is probably really gone with a void 0x1 flag?! However it's great (at least for European people) to have a last hope in mind!
But the reason I wanted to list all downsides is to make sure that you can also root Knox system without any hesitation - to keep the fun for rooting so to say

I just found this article about all myths & truths about Knox http://androidforums.com/boost-mobi...t/807188-guide-q-myths-truths-about-knox.html
It's very informative but I'm now confused again because the Article says that you can't use Knox apps anymore, once you tripped the flag:
"[...]If the KNOX warranty void line says 0x1 then you cannot use KNOX software as your device has been flagged as insecure.[...]"
Does this only concern additional Knox Apps not the default ones which produce the warning messages? Or are the Knox Apps just no installed anymore when going back on a 0x1 device or kind of deactivated by default? Could you check that?

Thx, I personally don't care about warranty. So this was really rather meant to only treat the functional downsides if there are any at all. I wanted to make sure to not have a trash phone with lots of battery drain or even worse: some irreversible hardware malfunctions after rooting. I'm also looking forward to KitKat but I doubt that the update will remove Knox again since even the army is already working together with Samsung now!
But according to iPAQS4 you can't do so much wrong with rooting (regarding the Knox environment of course)?!

According myths & truths about Knox
If the KNOX warranty void line says 0x1 then you cannot use KNOX software as your device has been flagged as insecure. By this I mean that if your workplace / company supports bring your own device to work for corporate emails etc and they use KNOX to keep security your device will not allow this. You are still able to use future Samsung firmware releases with the KNOX flag 0x1.
Confirmed. If you flash a new ROM TWICE, your KNOX counter will get 0x0. It will look like it is new.

Hey all,
I have an s5 on EE in the UK.
Heard about this Knox security software. It shows in my list of installed apps yet I can't seem to locate where it is?
Also debating root... Not sure if it's worth it, but did want to have a look at Knox.
Thanks

knox is a security implemented by samsung, it is active in the background, has no app for that. basically it "protects" samsung warranty better than the triangle in download mode witch shows how many imes you flashed, if you had roted ur device, in download mode will show u have 0x1 warranty voided.<---- thats basically KNOX.

No. ^
KNOX is a security container -> a place where you install apps inside a secure container that cannot be tampered with on a high level TrustZone security algorithm.
It's great that the person above said what it essentially does to your device, but what he explained above is what happens when the TrustZone between the software and the hardware is breached during root/downgrade/unsigned flashing. This essentially would allow the viewer of the KNOX status to know when the device does not trust it's own body with secure enterprise level apps (Application Integrity), hence the KNOX warranty bit will be set from 0x0 to 0x1 meaning "I will not ever run a secure container anymore".
You won't find KNOX 2.0 on your device as this is now a paid service for enterprises at a rate of $3.60 and it is only set up on your device when you have the KNOX 2.0 kit deployed on your device, unlike KNOX 1.0 where you get to enter KNOX mode anytime you want.
Anyway to root G935FD(Exynos) without tripping knox?
Cant wait to root my phone , but still worry about the screen replacement in the future
Do you guys have any idea?
No probably wont ever happen.

Root without tripping knox is possible if a Engineering Bootloader surfaces.
But I'm not sure whether even it can retain the 0x0 for a longer time.
No the system scans for any abnormalities in the system and if it senses any changes boom knox tripped
It's extremely unlikely we will get root without tripping knox and like @Ausboy 2011 said, the system will trip knox if it detects any system modifications. Something as simnple as installing a root app could trip knox in this case.
They released an engineering bootloader for the galaxy S6 Edge. So it IS possible. We just need to wait for that time to come. With the engineering bootloader you can modify anything on the system without tripping knox. You just need to flash EVERYTHING back to stock at the same time if you chose to remove said bootloader. Also, I know in the beginning phases of use of this engineering bootloader they lost use of their fingerprint reader. So there's always that possibility too. But we'll just have to see if/when that time comes.

This actually varies depending on your location. For instance, in Europe, tripping knox will NOT void warranty. It is against EU law to refuse a hardware repair just because the software has been modified.

That's true, but most places don't care, as they just send it to Samsung and they deny warranty repair because of tripped knox. You can of course get the repair if you take the fight up.. But really, who want to? I sued the place where I bought my S6, because they would not repair a KNOWN HARDWARE failure on the S6 (pink dots on front camera) after I had rooted my phone. They sent it to Samsung and they denied. By law they should pay the repair then.
I was told I was right by Danish Customer Service, but they needed my phone for like 7-8 months and I did not have my S7 Edge there, so I would be without a phone, so I called it.. For really, what could I win? I knew I would upgrade when the S7 came out anyway.

Here in the UK, Samsung will repair even if Knox is tripped. I have had a few repairs over the years and have always had tripped Knox. Some other UK users on here have confirmed the same.
Well that's nice. Sure they're are aware Knox was tripped? Because I was an idiot back then, I sent my phone in with a custom ROM, så they could not enter the binary, which was the reason they saw Knox was tripped.. When I said I would flash stock firmware, they said that was not possible without replacing something inside (the motherboard I think).

A Samsung rep in one of the repair stores told me that it doesn't matter if it has a tripped Knox as long as we put the stock firmware on the phone and it is NOT rooted. If it's rooted they will refuse.
However, I have known people to get the repair even when rooted.

Hi, I love this phone, but root has spoiled me. There are so many things missing from my device that require root, the most important of all, my precious adblocker :crying:
I know about proxy ad blocking but that doesn't work very well..
My question is, if I do root my phone, will I be able to unroot it and make it look like it was never rooted in case I need to return it while its still in warranty? I was able to do that with my Galaxy S4 by resetting some counters and flashing stock ROM, warranty guys didn't find out and I got my phone replaced. I'm not sure this will be the case with S7 Edge though, maybe Samsung found out ways to make this harder, I searched through google and I found no answers to this question.

After rooting if you want to unroot all you do is go
into your app drawer and uninstall the supersu app
and reboot the phone and you will be unrooted.
Don't worry about warranty, they don't even check
for root.
Good luck,
Have a great day!

Hmm, I'm not sure I want to risk it, I remember on my S4 there were some warnings while the phone boots - https://imgur.com/3Eoedfg , which had to be removed before I return it since all they had to do to check if the device is rooted is turning on the phone. Will I be able to do the same thing with S7 Edge?
when u root u trigger the knox counter, and there's no way to return it to 0
technically, with a knox counter 0x1 you already lose ur warranty, but not all countries look for that thing, so check how warranty works in your country

Thanks for your answer, I'm not sure where to check for how warranties work in my country. When I search in google all I get is info on what Knox warranty void means. I live in London UK, and this is where I replaced my phone that was 0x1 on its KNOX counter which gives me a little hope that they do not check this.

Don't believe me because I'm not totally sure, but I remember a thread here a while ago (maybe a month after S7 came out) where this knox thing was discussed, and I'm pretty sure an user from UK said that in fact samsung uk doesn't check knox warranty, maybe looking for that thread helps you, the thread was somthing about rooting or knox warranty

No unfortunately not, Knox is a fuse on the motherboard. Once tripped it burns. So far only way to get Knox back would be to change the motherboard

Yes but the apps and system dont read the statuts directly from the bootloader but from the kernel, this is why there is a kernel that has faked 0x0 knox, but the fuse is still blown yes.

You can use terminal to change Knox to 0x0 but still. S health will work and some apps, but not secure folder or Samsung pay
so, knox tripped and rooted on stock unmodified rom :
safety net fail : (no apps like samsung pay, Pokemon go, Mario run, snapchat login ,etc)
no system updates
samsung apps won't work : samsung pass, samsung pay, Shealth, secure folder, issue with private mode on samsung internet,
if you use a custom rom most of stuff CAN be fixed like
safety net pass with magisk hide (root)
s health work
private mode on internet
BUT some are permanent and can't be fixed even with custom rom so once rooted , no way back except buy new phone
samsung pass, samsung pay, secure folder
Remember that once you are rooted and knox counter is tripped (0x1), its irreversible and can't be "unrooted" or be official and reset knox counter even by flashing stock firmware though odin because since galaxy s7 the knox counter is not software related but its hardware. its an electronic fuse and if you root or install custom recovery etc the electronic fuse will broke and broken fuse mean tripped knox counter. this is because even flashing stock firmware is useless, as most of Samsung apps knox related don't only check root but also the knox counter, so unroot won't help. so think twice before rooting your device

su
resetprop -v ro.config.tima 0
Type that in terminal. It will make Knox show 0x0 on device ONLY. Download mode will still show as 0x1.

its useless, Samsung knox apps dont check if they see 0x0 but it just put some electricity though the knox fuse and if it get though it its ok but if the electricity dont success to get through the fuse it mean its broken so I mean knox is 0x1 and rooted.
fake knox counter is useless as every knox eligibility checks are hardware and not software. fake 0x0 is only for you ^^to reset the counter only way is the replace the motherboard, even Samsung can't reset it

There has to be some hardware abstraction layer, you can't just test the fuse each time, that would mean that the apps have really low level rights/api to do so wich is risky. The bootloader tests the fuse and writes the value to the kernel, wich can be faked to make some apps work.
If the value is checked by apps then there is a software value other than the hardware status.
But dont quote me on that.
For apps that dont work i think there is some selinux policies issues or root gets detected.
Why would devs include the fake 0x0 counter if it was useless ?
darn making me think twice about rooting now i mainly want it for debloating,apps ad blocking,viper4android,and a few mods like stereo speaker and camera mod
also the youtube mod which allows us to stream 4k (i know we only have 2k display) but i still like to stream in 4k

I have rooted for the exact reasons you stated above. Wouldn't go back even if I could. Using the terminal code I posted allows you to use some apps that rely on 0x0. Samsung health is one of them as I use it every day.

to be honest ive rooted every device ive had dating back to the htc hd2 lol
that's why i sent the xperia xz premium back was due to locked bootloader which looks near impossible to root
ill properly root i just didn't want to destroy any apps which made any hardware not work properly but if everything works (apart from samsung pay and secure folder) which i don't use both then should be worth the trip lol :silly:

And also I can confirm Samsung pass doesn't work also. However I never use it so that doesn't bother me. To be honest I would root just for viper4android. And I use android pay instead of Samsung pay which also works perfect
Still haven't rooted yet darn cart make my mind up I've rooted every phone I've had and it's the first thing I normally do :silly:
Does anyone think there will be more knox apps coming out which if knox is tripped we will be missing out on
Or what if Samsung make a few more apps go through knox like s health or iris scanner then we would be stuck then lol
I don't know miss the good old days where you could just go back to stock no worrys

I don't think they will release anything else knox related. At least not for the s8 anyway
S health and iris scanner work perfect now after root, they won't implement them into knox status don't worry.

I had to root for viper4android amd I'm not running renovate ROM and it so much better than stock.
In my opinion android pay is better and it's supported in many places. But that's my opinion.
If you root I recommend rooting with magisk. So you can use magisk hide and modules. Good luck and post here if you need any help :good:
