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

I think it's already clear that you can loose your warranty if you got a 0x1 flag. But I'd rather like to get a list of all the irreversivble consequences with your device itself when rooting etc:
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?

Going back to stock is posible whitout extra knox warnings. Knox will behave as before.

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)?!

I will flash a new ROM and I'll see if the KNOX stays like it was. But I'll do that later today or tomorrow.

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.

wiered it needs more researching .. mate knox flag is nearly impossible to reset and you are sayin flashing a stock rom twice fixes it !!
If I have knox bootloader can I:-
1) Root my device?
2) Flash different modem?
3) Flash any CM or AOSP ROM?
4) Flash any custom recovery?
I want these things to be clear for me.
Thanks.

I don't care about warranty.
I care about my freedom to choose modems and roms and edit my system as I want.
But I see Google android and Samsung in their way to loose more users by their new jails.

supposedly knox was for making the Galaxy an enterprise level security phone. so WTF is the warranty flag all about? right?

Well, the knox warranty flag has nothing to do with the phone's warranty. It's purpose is to signal to the knox container that the phone has been tampered with and is no longer able to provide the required security to the phone. Now, since there is no way to reset it like we could 0 out the flash counter with triangle away, it can also allow Samsung to see that your rooted or tampered with your phone so they can deny you warranty service. I haven't seen one post from someone that has been denied warranty service after tripping the knox warranty flag, we just all assume this will be the case since rooting your phone violates your warranty.

No, the Knox warranty flag has nothing to do with the phone's warranty only knox's warranty. The later statements were just the way it is. Samsung has never said your phone's warranty is invalid if the Knox warranty flag is tripped. But, if you read their warranty, it does say if you tampered with your phone than your warranty may be void. So, yes, you can infer that a tripped Knox warranty flag also means your warranty is void.

I have been searching for this answer for sometime.
Not sure where else I can look for, but I really want to know what happen (besides warranty issue) after knox trigger.
Is there anything that will happen to the phone beside the 0x0 and 0x1?
Can I still use VPN?
Can I still encrypt my sdcard and internal storage?
Basically, I need to know what is the difference between a triggered Note 3 and a non triggered Note 3.
Sorry if there is another post on this out there cause I really can't find it.
Thank you all in advance.

im not an expert but as far as i know you wont get ota updates or be able to use knox
i recently trigged knox and truth be told ... im having way too much fun with my note 3 n9005 and its getting way better ....
u can do more things if u installed a custom recovery and a kernel ... just read more threads about note 3 kernels and what they can do
note : flashing custom recovery or kernel will trip knox

I still own a S2 and I used to heavily mod it. I understand the feeling of rooting and not able to root.
I just want to know what is the difference between triggered and non triggered Note 3.
I am not sure why everyone is so worried about the warranty and how to fix the triggered flag.
I actually don't give a beep about the warranty and how to fix the flag.
As long as it doesn't affect the STOCK ANDROID functions (eg. VPN, sdcard encryption, internal storage encryption), I will be pretty fine with it.
The problem is, I am not able to find detailed explanation on what will happen to the phone after knox triggered.
Only affect is that you won't be able to use knox container anymore. Knox is a seperate enviroment to run your knox enabled apps. You still be able to get F/OTA updates and it DOES NOT void your device warranty.
NOTHING!! Despite Samdungs insistence that your warranty is void, your phone will be liberated!!
To me, this is a **** up by Samdung by alienating a large number of customers who, like myself, will NOT be buying another samsung after being a loyal customer for years!!
All manufacturers seem to be throwing some kind of spanner in the works for us who enjoy using our phones to their full potential.
Thank you guys so much for explaining.
request for an RMA Tab Pro 12.2 due flickering issue.
my tab is knox tripped. i even erased everything, no OS installed. they received Jan 8 and they send it Jan 9. just got it now and it was loaded with US version
so, don't worry about knox tripped. good job Samsung!
You are very lucky. I was denied warranty on my S4 due to Knox.
I've requested few times for hardware issues even Knox being tripped, and they honored my warranty repair/replace. It seems like Knox trip doesn't really matter if its related faulty hardware.

Headphone jack failed on my 10.1. Knox is tripped, but it was repaired, no charge.
for materiel they need to honor warranty ... but know is o security of data ... so i dont need
Was Knox reset 0x0? If so, is it possible to learn from the repair guys how they did it?
Yup lucky... They reject my s4 Knox tripped too. Now my tab stays Knox 0x0 ahah
Hello community,
I have a Canadian Galaxy S5(SMG900W8 - kltecan) with Rogers, currently running Lolipop 5.0 with the LRX21T.G900W8VLU1BOC1 build. I have it since 8 months and I'm beginning to be really tired of Samsung's bloated OS, sometimes it gets sooo slow and the phone becomes so hot. I know how to keep good care of my system and did many clean restores but it still gets slow after some weeks.
I want to install Cyanogenmod or something similar to completely get rid of the stock ROM, I know doing that will trigger the KNOX flag and I know it voids the warranty but I'm at a point I dont care about it anymore, my question is. In what other way will a tripped KNOX affecr my phone? For example if I ever flash back the stock firmware, will I still be able to use the features such as "Private Mode" and the Fingerprint scanner? Because those are some features I really like and care about. And also if I ever resell it, I want every stock feature to be functional...
What do you guys know by experience?
Ive read many KNOX threads before posting this one, it answers some stuff but not my exact question.
Thanks in advance!

Are you sure? Because I tought the whole KNOX software side in the phone was related to all the advanced security features like encryption, fingerprint, private mode etc... Isn't the private mode in the KNOX container?

Am I sure? I just told you it works fine on my S5, yea pretty sure lol
Tripping KNOX just switches the KNOX notification from 0x0 to 0x1 so Samsung can see it's been modified an don't have to honour warranty
I've heard it breaks domain/business related stuff, but I don't use my S5 in a business environment so can't comment on that, but for myself, everything still works exactly like it did with 0x0
