i have a galaxy s4 i9500 with android 4.2.2 and i read that if i update to 4.3 i will get a security feature called KNOX which tracks your custon kernel flashes and cannot be reset. and also you can't flash back to 4.2.2. is that true?
if it is so:
1.what will happen if you'll try to flash 4.2.2 with odin?
2.what other disadvantages KNOX have?
3.shoiuld i really care about KNOX if my phone's warranty is already void?
4.can KNOX harm my device by any way?
please answer the question by order!
i am thankful for any help i can get in this forum and appriciate everyone who answers my questions beacause i wanna know if i should update or not.
P.S.:if i have 4.2.2 can i install cyanogenmod 11 (unofficial) or i need to update to 4.3 to do that?
Knox doesn't track custom kernel flashes specifically, it detects if you flash anything non-samsung (whether it's cf-autoroot, custom recovery or whatnot). It just says knox 0x0 or 0x1, if it's 0x1 your warranty is void. There is another counter detecting number of flashes, but that can be reset with TriangleAway. Knox cannot be reset. EDiT: TriangleAway only works on i9505, sorry.
1. If you don't have a knox-enabled bootloader you can flash an older rom version. Boot into recovery mode, if you see a knox counter there you cannot flash older firmwares than the one you already have (on i9505 there was one knox-enabled fw before 4.3). If you don't see anything knox related you can flash what you want, but once you flash a knox enabled rom you cannot downgrade to older official samsung roms.
2. Besides not being able to reset the knox counter there isn't really anything special. Atleast none that I have noticed. SuperSU asks if you want do disable knox-features upon first run.
3. No, then it doesn't really matter. Unless you really want to flash an older firmware from samsung.
4. No, it's a samsung feature.
If I were you I'd flash official 4.3 builds anyway, as they're generally much faster and much more stable, atleast for me on i9505. And the improvements outweigh the downsides of knox. 4.3 feature list: http://www.sammobile.com/2013/10/18...al-android-4-3-update-for-galaxy-s4-gt-i9500/
Hi there
My galaxy s5 got into water yesterday so I checked the back of the phone and saw the litmus paper became red, then I thought that now I can finally root my phone without concerning lol ), then I flashed Modem: XXU1ANI1 and intend to flash rom later. But then I told my friend who works at Samsung Services and he checked my phone and said that it has no problem so it is still under warranty. So I want to ask you guys that whether I flashed the modem XXU1ANI1 affect my warranty or later if I can update stock firmware via OTA. Can I flash back to the latest stock modem XXU1ANG3 for G900H Vietnam without tripping knox? or if it has any problem?
Please help me , I really appreciate any help you guys can provide.

Yes, you can flash back to your stock modem without tripping Knox (if it has not been tripped).
To check whether your Knox was tripped or not, you can use Phone INFO ★Samsung★ app and look for the Knox Warranty Void status (under GENERAL INFO section).
Thank you so much
Hi,
My cousin owns a Galaxy s4 i9505 LTE and he wanted to root it. Since i was using custom rom on my S3 i9300, He asked me to root his phone and i told him that the knox security will mess things up. Anyway i rooted it with CF Autoroot and root was successful but the phone started restaring periodically and he wanted me to restore it back to stock rom (Unroot). He bought it from UAE and the build version was I9505XXUGNH8. Since we didn't find any firmware for UAE from sammy site, he searched the google and found a link (samfirmware) and downloaded the firmware. Then i flashed it via odin. All is good.
Now he want to root it again but the SElinux status says Enforced. Tried towel root,kingoroot and other stuffs.. No hope. The Knox says 0x0 and knox void is 0x1. Android version is 4.4.2. please help me to root this phone.
Thanks in advance...
Use cf auto root. It's the only root method that works.
Afterwards make sure to delete everything knox related. There are plenty of guides out here that tell what to delete.
Thanks for the help.. and if you don't mind, can you please tell me where to find those threads about deleting knoz files and what should i do to get a custom recovery in i9505?????

Hello
i have the SM-N910C running the official lollipop firmware,
days ago i've rooted it using CF auto root through the odin,
And it was successful, but the question is the CF auto root
replacing the stock Kernel to another one while flashing ?
cause when i reset flash counter using triangle away even without restarting the phone it still shows in triangle away:
counter: 1
Binary: custom
system: official
but in bootloader it says:
current binary: samsung official
system status: official
secure download : enabled
knox warranty void: 1
rp swrev: 1
and the reactivation lock is off in the settings and the bootloader
i just need the software updates after root
and resetting the flash counter to Zero
and to know the kernel is it stock or custom
anyone could help ?
and sorry for any bad english, thanks.

Hi, cf autoroot doesnt replace your kernel, so u should still have stock kernel.
and also as far as i know, triangle away doesnt work on note 4 ... so right now there is no way to reset the counter to zero.
and 1 more thing is you may have posted this question in the wrong thread, you should have posted it in the Q&A thread. ^^

Good luck trying to figure out how to reset that counter permanently - so far no one managed to find a way to do that since the introduction of KNOX back in 2013.
So guys, i got a little bit confused about knox 0x0 - 0x1 - root - custom roms etc.
I own a note 3, when it was with kitkat i've installed twrp through odin and got "knox 0x1 (1)" then i went with official lollipop firmware, and now i've reflashed twrp for installing cm12.1 getting knox 0x1 (2). From what i understand, there is no way to revert knox to 0x0, isn't it?
If i had a brand new note 3 with lollipop and knox 0x0 could I install custom roms without tripping it? or even get root permissions on the stock rom?
what also keep me confused is: why there are so many alert in the note 3 section on xda about tripping knox while in the s5/s6/note4 sections everything seems to be much easier? can you please explain me?
PS: execuse me if i've had not been so clear but english is not my first language
Nope, the device's virginity is lost, that baby is done, unless you have the Exynos version, where KNOX status could be reset
Thanks for answering. So i got a friend that would like to install the cm12.1 on his knox 0x0 N9005. will he trip it?
Not much idea mate. But I think there is a possibility that he might not trip it, at least I have seen something like that. Obviously the standard method of flashing a ROM via Odin or or from custom recovery will trip it, but I think there's a way to avoid that, not the usual way of course. You might ask to those who have already done it, or in the CM topic itself, if there is one.
