[Q] Information needed after being inactive for a long time. - Galaxy Note II Q&A, Help & Troubleshooting

So after being inactive for months I came across stuff about "KNOX"(Knox free etc) and MIJ MJ5 stuff and that it looks like its hard to downgrade or something like that, can anyone explain me what exactly KNOX is and what MIJ is?
I assume MIJ and MJ5 stuff is the firmware version.. and roms using those tags in their title are based of them? Or can I only flash those when I have that firmware?
I actually didn't even have any problem yet.. but I've been running official MIUI for the past months anyway..

If you search at forum little bit you'll find all your answers

Sure, maybe you have to search better I suppose.
OK no problem you need help you are saying if I understood well, knox is new security function for secure phone's communication for company use etc, it is using many levels of security starting from bootloader and goes to system etc etc Google it for more information, also knox checking your system for rooting etc and voids your warranty (look at note 3 forum), is difficult or impossible to remove it, but if you have already install it drketan made a patch for n7100 which is removing successfully knox from your bootloader.
http://forum.xda-developers.com/showthread.php?t=2500823
Follow the instructions and knox finished from bootloader, after this
you can downgrade to 4.1.2 use triangle away flash stock f/w restore warranty etc
Little bit more searching noone hurts

So if knox is installed, i will still be able to root, but its somehow setting a value which manufacturers can check and see if I rooted or what? (I also don't believe I have Knox im not sure, i updated to 4.3.x once via odin but only used that to fix my EFS and then go back to CM10.2 and or MIUI (depends on my mood))

You can see if you have or not at download mode volume down +home+power at last line, it is writing knox something.... . Knox is present at mj5 second leak 4.3, if you have it you need to use drketan's 2 patches to remove it before downgrade.
Are you ok now? Your questions answered?

Newbie help on 4.2 to 4.3 tmo (KNOX)

Hello,
Fairly new to android and rooting. Only rooted one phone (Dad's gs2 bc it had firmware and camera issues) but I was successful.
Using a virgin Galaxy S4 on tmobile since april only mild battery issues. Was waiting for uodate and shocked that we only get jellybean instead of 4.4 kitkat??!!
So question:
Upgrade and lock bc of KNOX and just wait?
OR
Dont upgrade and root and add kitkat now?
Is it worth the upgrade?
Galaxy s4 on Tapatalk
KNOX doesn't lock your phone. Its builtin to the 4.3/4.4 bootloader and if you root or flash roms, it trips the flag and voids your warranty. That is all. If you don't care about the warranty, flash away. You can root your current firmware and flash the 4.3 or 4.4 roms that are on thr forums that have KNOX removed. I'm on 4.2.2 and Ive upgraded using flashable roms and came back without having to worry about KNOX

That would be handy, as bouncing around the threads on the update and the initial ROMs being developed leaves a lot of questions and there are a number of soft bricked devices because of it.
Apparently, if you want to stay totally away from knox, you cannot simply flash the new radio as-is, as without having loaded the new knox bootloader, a number of functions will not work. And if you just flash the new OTA based ROMs, you can have problems also,
Work is being done to de-knox the radio, but I don't know where that stands. Nor am I sure if when that is done if you will be able to flash and use the new OTA ROMs and also revert to 4.2.2 without having to first revert to previous radio.
So again, a guide on living with knox would be helpful.

I'd like to know whether, if I upgrade to 4.3 using Kies (I'm on rooted 4.2 stock), I can re-root and remove Knox (as I've done in 4.2). I know I can re-root, and permanently void the warranty, but I don't know if Knox is removable in 4.3.

If you upgrade to 4.3 via Kies you will trip KNOX if you change ANYTHING. Once it's tripped, you can't clear it.
The only way to avoid tripping the KNOX flag is to use a rom with KNOX removed
Can someone clarify something for me. Does having the 4.3 bootloader and knox 0x1 prevent you from flashing CM/GE/AOSP/Non-TW4.3+ ROMs? I've been staying on the old bootloader and am considering just updating. If the knox 0x1 only affects warranty and not flashing of any ROM I want, then I don't care if I have 0x1

Only voids warranty afaik. Why not stick with the old bootloader and just flash new roms without the new knox bootloader? Best of both worlds.

Np. In my honest opinion, this new bootloader is just another middle finger to the consumers under the false pretense of solidifying security measures for the few coorporations that have actual need for KNOX. This is Samsungs way of avoiding responsibility for failed hardware. Okay enough ranting lol. New bootloader serves only as a way to inform Samsung or the store you are returning to that your warranty is void.

Skipjacks said:
As for upgrading to 4.3 you do not need the 4.3 bootloader and you don't want it. It has a way to show that you've previously rooted the device that cannot (as of yet) be reset.
Just flash 4.3 ROMs in recovery. Anything you find in the development section will work fine. But if you want Wifi Calling you HAVE to use a T Mobile specific Touch Wiz ROM. You cannot use just any Touch Wiz ROM or any AOSP ROM at all.
If you want the T Mobile Wifi CAlling on the stock 4.3 rom and don't want all the other BS that comes with it, use this guide...

Umm, many people with real jobs have security requirements for their mobile devices. KNOX has nothing to do with Samsung attempting to avoid responsibility for hardware failures. They have nothing to do with each other. Where did you get this BS from?

I specifically stated in my first sentence that it is my personal opinion. I also stated that corporations do use KNOX but not to the extent that everyone needs to have it pushed out to them without a choice. Quit getting your panties in a bunch and learn to read.

[Q] 4.3 official, need to root without tripping KNOX

Hey, as my Note II is still under warranty for a long time, I'm looking for a 100% sure way to root without my files getting lost and the KNOX counter going up.
Right now:
Fully stock Note II running 4.3 (N7100XXUEMJ9, updated via Kies)
What I want:
Rooted stock ROM and stock kernel, just to use apps that require root access.
Warranty not void
Thanks!

I have PM'd a few Mod's who had closed threads concerning rooting without tripping knox, who from their post history at least, looked like they where in on the discussion on whats going on.. Nothing back from any of them yet (even asked for direction to the proper thread to get updates)
Sadly, as the last thread I saw was closed on NOVEMBER 6th due to IMEI and HTTP concerns, there have been 4 new release's for the Kingo software, and yet I cannot find a single XDA thread (admittedly 20min~ is about my limit for the site search engine) about if any of those 4 updates resolved the issues XDA had with the root tool...
I desire to simply remove the bloatware, not void my damn warranty... screw you Samsung for disabling the DISABLE feature for BLOATware...

I restored my knox warranty!!!!!!!!!!

So, I was on CarbonKitkat rom by @F4k and I wanted to return on original samsung firmware.
I flashed that with odin:
I9195XXUAMF6_I9195VFGAMF2_I9195XXUAMF6_HOME.tar.md5
but won't boot, so I reflashed it and got an error:
image size too large!! W:1000, H:1920
display image fail
SECURE FAIL: KERNEL
So, now in download mode I saw that Knox Warranty Void flag was 0xfffffffc (or similar, i have not counted how many 'f' were there)
I searched on google and founded that i get that error on boot because I did a downgrade, so I can get all functional by flashing a newer firmware, so I flashed:
I9195XXUBNA2_I9195VFGBNA4_I9195XXUBNA2_HOME.tar.md5
And I got:
Phone boot.
Working wifi.
Knox warranty void 0x1 on Download Mode, but not yellow string on boot, What does mean?!
0x1 means you triggered knox.
0x0 means you didnt trigged knox
0xFFFFFFF probably means possible downgraded device/ not acceptable value.
so in the end nothing is changed.

There's a difference between practical and theoretical impossibilities. Theoretically speaking, you're right. There might be a way to restore KNOX, but we just haven't figured it out yet.
Practically speaking, there's no way to do it yet and it doesn't seem likely there'll be a way to do it any time soon (*). Therefore, it's practically impossible.
(*) It's unlikely there'll be a way to do it for two reasons: it's difficult and there's barely anything to gain from it.

Afaik the efuse, qfuse is present on all snapdragon devices and every manufacturer is free to use them in any way, Samsung decided to use in the knox security, motorola use them to lock the bootloader
The exynos devices could be reseted with a bootloader i think they don't have efuses
A modified bootloader might "mask" the knox void flag but that would break the booting and from this point i need to read and update my knowledge on the topic that is really "old" let's say from January
To be clear snapdragon 400 has efuses qualcomm put those in the chip Samsung is using them with knox and for bootloader increments that's why we can't go back to an old bootloader

Replace Bootloader and reset Knox?

My Samsung Galaxy S3, which I got last April, came to me from Virgin Mobile (same model as Sprint) running Samsung's build of 4.1.2. When the update came, I upgraded to 4.4.2, rooted, and eventually flashes Philz and CarbonROM. My knox has been tripped. Can anyone tell me what update the Knox bootloader came with, and why I can't revert to it? I believe it came with the 4.4.2 update, but I'm not totally sure. So, why can't I revert to a Knox free build and bootloader? I have read that it causes a brick, but how and why can't I simply get rid of the Knox bootloader by flashing over it and going back to stock 4.1.2? Any help is appreciated.
Sent from my SPH-L710 using XDA Free mobile app
It's a efuse, so if you try to revert to pre-knox it trips the efuse and bricks. Knox is geared towards enterprise and, I would guess, government users as a security measure. Unless it is going back to Samsung you don't need to worry about Knox being tripped.

Thanks. Can you tell me what an efuse is, and what it has done to brick the device? What part bricks it, and why can't you get rid of whatever bricks it? I viewed a YouTube video where someone did it on a note 3. Sorry for the noob questions.
Is it possible to format everything and force updates to whatever partition particular items are in? Thanks. It probably won't go to Samsung ever.

Here's a pretty good article about it:
http://omegadroid.co/wanted-knox-void-warranty-0x1/
http://forum.xda-developers.com/showthread.php?t=2541343
In short, it's not possible because the system physically breaks something inside your device and uses that as a flag for whether you have tripped Knox or not
You brick when you try to downgrade because low level parts of the system besides the bootloader get flashed properly, but when it gets to the bootloader Knox tells it that it can't be flashed so it will fail there. From there, you are stuck with a system that is running two sets of incompatible low-level firmware and so the phone refuses to boot in a mixed state such as that
Thanks guys. I understand what you've said, except that something physically breaks in my phone. What was physically added, by the 4.3 software update, that will brick it other than the incompatible software and bootloader? Also, would you mind explaining how exactly someone reset it on their exynyos note 3? A video on YouTube is available about it.
And basically, you're saying that Knox just prevents me from flashing a bootloader? Does that restriction only apply to old Samsung bootloaders, or all including third party? Thank you all so much.

Hi!
Nothing physically. eFuse means electronic fuse, but not as in a discreet physical fuse. Just that the MK3 bootloader makes it so that the warranty/Knox bit is irreversible, like a fuse.

Knox does several things. Preventing you from downgrading the bootloader is consistent with one of its purposes: to not be able to erase evidence that the phone has been tampered with.

I thought that since there are custom Roms, kernels, and recoveries, there might be custom boot loaders. So there is no way to erase a bootloader either?

You erase/corrupt a bootloader and your phone loses the ability to boot. And this doesn't just apply to Samsung phones, all devices work like this. The bootloader is what commences the boot up process and without it the device literally doesn't know how to turn itself on.

Question about voiding warranty.

Ok so I'm not asking on how to install a rom or anything like that. It's just that I haven't rooted a phone or installed a different rom in so long that I just don't know what's changed. So I just got a LG G4, and I wanted to install Cyanogenmod just because I like the customization options it had back then and I'm sure it's gotten better now (on that note can you still revert to stock roms on phones?). So here's the thing, I just got the phone today, and it's brand new. Now I'm afraid something might go wrong with the phone (other than bricking which would be my fault) and I want to be able to send it in and get it fixed or replaced. I remember a while back there was something you'd installed that it would reset the counter (flash counter?) so it would seem like it was not rooted. Is that still around or anything like that so technically I'm not voiding my warranty just yet?
Why don't you read the forum a little bit more

Currently the only you can do on this phone (unless you have tmobile or international) is root as the bootloader is locked. The only possible roms we'd have are stock modded roms that we can flash the system.imgs for.

I do have T-Mobile., so does that mean I can or can't? So if I understood this correctly, stock modded roms can be used to reset the flash counter or do you mean revert it back to unrooted stock or both?

I thanked you on accident I wish I could unthank you.
But yeah just read up instead of posting about flash counter which is non existing and have never existed on a LG phone.
