What are the chances of the device getting rooted then? I noticed the GS4's bootloader was locked but it was able to be rooted. I don't need custom ROM's just root. Any answer would be appreciated.
Thanks!

I would say the chances are pretty good that root will be achieved. You will just have to wait till an exploit is found. You could do what I did and get the tmobile version which already has a custom recovery where you can flash a rooted stock rom.

Is the T-Mobile one has att LTE band ?
According to the FCC lab report, yes it does.

That is correct. No one knows for sure yet. All we know is that it has the correct radio and bands. Hopefully it will work the same as the S4.
After some more digging it looks like the write protection enabled only applies to the bootloaders and other lower level partitions, which means we might be able to flash the boot/recovery/modem partitions still. However, it WILL trip the Knox flags, which means the warranty is void and will NOT be able to run any Knox apps.
None of these things bother me since AT&T doesn't know about any of this stuff and Knox isn't useful to me.

Where you able to verify this using the att build? In other words, do u know for fact that the bootloader if locked?

With that, even the Galaxy S3 shows QUALCOMM SECUREBOOT: ENABLE after it is unlocked, and WRITE PROTECTION: Enable applies to the bootloaders and other sensitive partitions.

Ya, it seems like the kernel is encrypted, I have been unable to rip it apart with any current methods.
So basically we can root the device but the possibility of flashing new ROMS and kernel's will be extremely difficult?

Yup..if the old root exploit still works (if it does not, then pretty much toast). The bootloader *cannot* be replaced yet (even in S4), if you were lucky and had the earlier bootloader then you could "loki" run custom roms/recoveries. Otherwise the only option appears to be the "kexec" type method (safestrap), yuk..get one without a bootloader lock (hoping T-MO does not lock it and allows unsigned kernels and recoveries)..
Although I don't understand why ATT would this, the above methods for S4 has made people who didn't understand the process fully to go back to Samsung//BB service centers to reflash the stock f/w.

Actually getting root is going to be difficult. An unpatched exploit will be needed. Rom's and kernels will be the extremely difficult part. Samsung's credibility is on the line for a secure business solution with KNOX so you better believe they are going to make it hard if carrier's like ATT decide to lock down their devices like they have.
Yeah, I'm still just trying to understand why ATT is doing this. Hopefully the old root method works then, otherwise it is a deal breaker for me.

I don't think it matters at this point. My understanding is that with the custom recovery already available you can flash a rom with root and with knox disabled. There is already a dev working on striping knox out in the dev section.
Geez, it's just hard imagining a phone like the Note 3 never having root access. But hey if that's what happens, I guess there's nothing you can do.

That's correct. If a bootloader is unlocked and you ODIN flash a custom recovery and install su and push super su. The kernel is not SELinux permissive, then we just need to wait for the source drop, compile a new kernel. The important thing is the bootloader unlock and knox security allowing unsigned kernels and recoveries. From the S4 T-MO thread it appears that the T-MO version allows that..so it will not be a big deal..ATT ones of course you are pretty much toast.
Just been through training for KNOX at work - and without blowing my NDA's - i'll pass on this for you all
If you EVER want to use KNOX - and you run one of the leaked 4.3 roms - NEVER NEVER NEVER flash any custom binaries to the phone again - you can only EVER run an offical untouched rom.
If you ARE running a 4.3 rom - reboot your phone into odin mode and see if you have a KNOX warrenty bit set to 0x0.
if you do - and you EVER want to use KNOX (and after training - im going to be using it meself) - you now can not roll back - or install a custom kernel or pretty much anything apart from further factory roms.
If you install anything else - the KNOX and TIMA systems will blow a fuse on the motherboard of your note2 and you will get flagged with KNOX warrenty bit 0x1.
This is not reversable - ever - without a board replacment.
The only effect will be that you cannot ever run KNOX after this - private or enterprise versions.
The first leaked 4.3 rom didnt have this enabled - the second one did (UEMJ5).
This is enforced in the bootloaders - once you get it - you cant go back.
If you dont care about KNOX - go hard However if your are going to use a BYOD type setup at your work and they want to enforce KNOX and youve blown the fuse in the motherboard - to be blunt - you are screwed Its not reversable sorry.
If you dont know what KNOX is actually about (if youve read "Little Brother" by Cory Doctorow think phone inside a phone type things) check out https://support.samsungknox.com/home and have a chew through it - there are some very good parts to it....
In any case - if you dont care about KNOX - go hard - nothing has changed.
If you DO care about KNOX - your not going to be able to change the firmware on your phone at all ever - if you do you will lose permanently the ability to run KNOX.
if you want to use your phone for work and work wants KNOX and your a custom rom person - your ****outaluck =)
And KNOX is not just the apk's..... its the entire stack from bootloaders upwards....

I didn't think the Note 2 has the eFuse on its motherboard?
I'm running Hurricane ROM and it hasn't got any KNOX and the new bootloader stuff. I think this problem is with the "original" (leaked) 4.3 ROM
On the one hand I object to this kind of control by Samsung, it's my phone and I resent them wanting to control it.
On the other, I understand that many businesses don't want their staff using their network connections or accessing their data without protection and separation.
I do my best to not use my phone at all for my employers's business, but if they wanted me to and told me knox was obligatory then I would tell them they would have to provide a mobile device for me to use as I would tell them I could/wouldn't be able to promise that I wouldn't lose knox due to custom roms.

Backporting and using a fuse that hasnt been exposed or used previously - apparently there are unused fuses in the system there
in reply to Chris189 "I'm running Hurricane ROM and it hasn't got any KNOX and the new bootloader stuff. I think this problem is with the "original" (leaked) 4.3 ROM "
the original didnt give me the fuse setting - the new rom did give me the fuse setting
im curious to find out if a samsung signed rom with knox disabled will allow a rollback offically - but i dont think your going to get any leaking like that.
And from 2k14 going forward - all samsung devices will be running this
also take note of the "SELinux" permissive / enforced state..... enforced may break some apps....
anyways - back to work - "hoo...ray"

From what the Samsung trainers were saying - once KNOX is on there and has that KNOX warrenty bit available (can be seen from odin mode on the phone - power , vol down and home when booting) a rollback will blow the fuse even to a factory rom - not really willing to try it on my note 2 to confirm sorry
Should have said... any idea of rooting 4.3 by whatever method invalidate this KNOX thing.
Had a feeling that most rooting involve flashing at least a insecure bootloader for it to work?

Did you have your IMEI when you flashed back? May have needed to restore your EFS? Or reflash the original modem?
To put the Knox worries aside, I did the following test.
Install newest leak (MJ5) bootloader (with knox). Warranty bit was 0.
Installed MI6 and installed knox which worked. Warranty bit was 0.
Flashed CWM recovery from Odin, suprisingly knox was still working. Warranty bit was still 0. Binary flash counter increased
Restored CM10.2 Nandroid backup. Warranty bit was still 0
So it seems that with the MJ5 bootloader, no knox fuse is being blown and you are able to rollback to a previous version without issues (if you have backed up EFS when you want to go back from 4.3 -> 4.1).

if u want to go back to 4.1.2 u need newer builds which have the new EFS changes ( older builds will show fake IMEI if u don't have backup from the old EFS )

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

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.

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?

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.

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

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?

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 !!
Hello all,
I searched the forums round and round, and couldn't find my answers so I hope you will be able to help me out.
i'm looking for a new phone and decided I want to go with the S5. that was before i learned about KNOX and it's wonderful ways.
i'm a heavy modder, who will most definitely use a custom recovery and ROM/kernel.
my questions are:
1. would it be possible to flash a custom recovery / rom / kernel / modem despite KNOX being preset?
2. other then getting this 0x1 and voiding my official warranty, are there any other result to this? will something not work?
3. assuming I get an unlocked international phone, is there any need to mess/change my FW? or is that just part of guides for rooting without tripping KNOX ?
Basically, I want to be sure that I could do whatever I want to the phone without getting stuck or turning it unusable because of KNOX. my current phone is a Nexus 4 and it has been heaven. I want to preserve this feeling
thanks for the help guys, appreciate it!
Did you tried Towelroot method for rooting your device? I heard that doesn't trigger knox..
I would imagine my rooting the phone is the least of my worries.
as far as I know - and this is one of my questions - flashing a custom recovery and or rom will 100% trip KNOX.
not that I care, I just need to know if this is true..and my other questions as well
thanks!
A brief answer
If you - as you say "i'm a heavy modder" Samsung phones are not for you
I've heard tales of people having issues flashing modems when knox is triggered. I have not checked that out for myself Joe have I searched any further into the matter.
I plan on breaking knox soon though because screw knox.

This answer really worries me to be honest.
could you elaborate?
I don't really care about KNOX, and as long as I can mod away and jump back and forth between modems/roms/kernels - I don't care for the warranty.
If indeed there is truth in the matter, and modem flashing will become a problem if KNOX is tripped, then this would be a deal breaker for me on this phone.
anyone care to add more info here?

You can, but you will always have problems like network, connection,calls, bugs and so on
Samsung devices do not provide the old pleasure as previously
Knox killed freedom of developers and people who like customizations
I would really appreciate an answer from someone who knows for sure.
does tripping KNOX disables the option to upgrade/downgrade the modem?

No, KNOX tripping is only at the moment a warranty void solution for samsung. its like the flash count flags.
basically if you trip knox. you're already in it. you do what you want

I bought my phone with ANCE firmware and the KNOX was tripped in the first hour by CF-AutoRoot. Now I'm on ANG2, flashed with Odin and the modem is updated correctly.

Now i'm a bit confused when you say you upgrade the FW, you mean the modem baseband, right ?

Exactly, but with full stock image flush (including bootloader). The full stock tar.md5 form sammobile includes the modem/bootloader/rom. I think that the important thing is to have a modem which is compatible with the bootloader (same version). Didn't try to mix different bootloader/modem(baseband) versions.
Tripping KNOX will only disable the feature which allows you to store some data on a encrypted part of the device (Mostly comercial use) when KNOX is tripped any data stored on the 'special' partition is destroyed.
So there are only 2 things that will be affected, your warranty (Not a problem in Europe) and the special partition that I explained earlier.

Thanks guys, excellent replies !
So...I did it !
I went and bought a brand new S5, and tripped KNOX within the hour. Man, did it feel sooo good !
custom recovery up, rom up, here we go!
Hi just got my s8 plus and I'm just wondering I want to root and been searching around about what tripping knox brakes but keep getting mixed views
I will be rooting and flashing a custom Rom and kernel would someone be kind enough to list every app that get broken and is not fixed even by a custom Rom or kernel (like iris scanner,s Health, ect)
As I really want to root but don't want to damage too many apps in the process
Many thanks also my model is the SM-G955F

Well if that's it then I'll go ahead and root as I don't use them 2 apps anyways
Thanks

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.

Thanks I'm going to have to root I miss it too much I've given it 3 weeks and I've never used secure folder or Samsung pass so I won't miss them and Samsung pay although i haven't used I will miss lol
Isn't android pay ment to be better anyway?
Thanks again

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:
