If I flash a custom recovery, it will trigger knox flag?

Yes, that is what the Knox flag is meant to do. If you flash anything into the Recovery partition, the flag will be tripped.

Install 4.1.2 custom rom on 4.3 bootloader

Is it possible to install 4.1.2 custom rom on a note2 which has official 4.3?
Bump.... Any one tried this?
That's what I'm wondering too! It's what's keeping me from updating bootloader/rom right now
Bump.. bump? Anyone running a custom 4.1.2 rom on 4.3 bootloaders?
I have had no issues. With roms on 4.3 Other then my Knox counter tripping.

How did you install 4.3 bootloader, did you upgrade from 4.1.2? Can you point me to the instructions for the same?

Why? Did you already flash a 4.3 rom? Just restore a nandroid.
No it is updated officially to 4.3, so has the new bootloader.
So can't reverse the bootloader, but the question is can I install 4.1.2 based rom now?
All I did. Was odin the rooted stock 4.1.2 put on cwm and flashed rom

I was going to say just use Odin to return to stock JB. I found that advice in a thread about this for at&t, but later on the thread a Canadian user said it worked for him.

Can we root the official At&T 4.3 yet and KNOX questions **Solved

Can we root the official At&T 4.3 yet?
I Odin'd my phone back to 4.1.2 before sending it out due to a bad headphone jack. It updated to 4.3 today and curious when my replacement comes and probably has 4.3 on it already, can it be rooted quick and just run a rooted stock for a while?
EDIT
Good KNOX info http://www.kingoapp.com/help/samsung-knox-counter.htm
This is what you need:

after you do it you will have to update SU through the play store and then it will disable knox for you as well..

Thanks alot!
No worries! Just keep in mind after you do it you'll get notifications about knox and security. Ignore them and head to the play store to update SU, because you won't be able to open SU till then. Also bear in mind that this will trip the knox counter and there is no going back.....it will void your warranty! You have been warned

KNOX counter is seperate from the Flash Counter? Before when I was on stock 4.1.2 and flashed custom 4.3 and 4.4 roms , I never saw any KNOX notifications or warning...Is this new with the 4.3 OTA?
My first phone had headphone jacks issues too. i reset it with odin and had it replaced with no issues from at&T. Now this one is repeating the same issue. I Odin back to 4.1.2 and took the 4.3 OTA before i call them and they want to remote desktop into my phone like before.
If KNOX only comes with the 4.3 OTA i wont take it if the replacment phone doesnt come with 4.3 preloaded
Anyway of confirm KNOX status on my phone? or is it something at&t doesnt look at
I Rebooted into download mode and it says KNOX Warranty VOID:0
So i guess I am good with this one......?
Never saw the KNOX before in download mode...So it must have came with the 4.3 OTA
If the replacemnt comes preloaded with 4.3 and I root theres no going back for non rooting warranty issues
If it comes with 4.1.2 i should be ok...cause my others came with 4.1.2 and i rooted and installed 4.3 and 4.4 roms , odin'd back to 4.1.2 and never saw knox before.
It's new in the 4.3 OTA MK6. It is separate from the flash counter and CANNOT as of now be reset. They can see it in the same place the flash counter is.
It will show 1 which means warranty void. If you can get one without 4.3 do it
This is what it looks like now:
Triangle away still works but the knox counter stays no matter what!
Edit: If it is still showing 0, then you are good to go
Geeve
thats good news LOL
4.3 preloaed=screwed if i root it
4.1.2 preloaded= no knox, free to root, flash, unroot and reset , send back with any non root related warranty issues.
Glad i didnt root the OTA in the meantime while i wait for my replacment..
Thanks for all info and help Geeve
You got it and no problem
Geeve
So i guess no custom 4.3 or 4.4 rom will install KNOX behind our backs..Just the OTA and any possible updated bootloaders if we dont pay attension and flash one
Baseband/Modem updates should not install knox...correct?
Correct! all the custom 4.3/4.4 roms use a leaked bootloader and most if not all have the knox stuff removed. It is only the MK6 OTA for our phones that is screwing us right now. We can still root and flash, but warranties are void..
Geeve
This topic won't help me?

Looks to me like you have the official MK6 OTA. I wouldn't mess with it if you have to return it. That other thread wont help.

Please look at this bootloader

Ok so I updated my girlfriend's note 2 to 4.3 via odin the offical stock one and I got this on the bootloader.
I want to add that the update failed a couple of times when flashing the system but the third time went ok and the phone booted.

Latest BOOTLOADER is locked now there's nothing we can do yet. Don't trigger the KNOX counter it will void warranty forever. Please do some research how NOT TO TRIGGER the knox counter by means of flashing.
I know the knox void warranty yes. I mean the "RP SWERV: A2" what's that?

Knox and upgrading

I have a T-mobile Galaxy S4 and it's currently running danvdh's GPE edition. I am considering updating via the OTA to get the new baseband/radio. I currently have the mixed MK2/MDL radio/baseband. I know that I'll get knox if I update...but IIRC, the Knox apps are able to be removed, and flashing new ROMs will trip Knox, but aside from voiding the warranty, what else does this do? Nothing? Lol

This is a full and complete answer, by the way. That is all it will do aside from the warrent.y It does not affect your daily use at all.
Just to confirm though. If I go back to complete stock and do this update and then apply any kind of root it will hit the Knox flag right?
Right now mine is still 0x0
Pretty sure it's flashing a custom recovery that trips Knox, not rooting.

I would like to point out that as of right now I have not seen a method to root 4.4 without tripping knox counter. 4.3 yes Saferoot works but not for 4.4

[Q] Needing a bit of clarification before purchase

I'm coming from an HTC device which required both rooting and flashing an unlocked bootloader, so I'm a bit confused as to the ease as to which it seems this device can be rooted.
After digging though the forums, I have a few questions:
I'm seeing nothing in regards to unlocking the bootloader, so I'm assuming that's not an issue/anything important with this device?
I'm seeing root methods using both ODIN and Heimdall, and I'm at a loss (again, I'm coming from an HTC device) as to which is the best?
What I'm looking to do is have a fully open device (flash any ROM, kernel, radio, etc. I'd like); I understand Samsung has a flash counter (KNOX, I believe), and I'm fine with that (as long as it doesn't lock me out at some point ... does it?); and I'm not sure which method would give me that.

You can root/unroot this device with ease. I believe the only gs4 with locked a bootloader are the Verizon and sprint variants. I could be wrong. But I think those are the 2 carriers that lock you out of your phone. Anyway there's very little chance of you getting locked out of your phone unless you flash the wrong files. Odin is definitely the best way to go for Samsung devices. I've been using it since the vibrant came out.

When you root your phone and start flashing ROMs, KNOX will be tripped to 0x1 but that will just void the warranty. And I just found out a week ago that Samsung says they will still honor their warranty even if KNOX is tripped.
ODIN would be your best bet. I haven't even heard of Heimdall.

Awesome, thanks ... I see you're on T-Mo as well; I was just going to stick with CyanogenMod but, any ROMs you recommend for the T-Mo variant? I prefer a pretty clean interface (eg. no TouchWiz), with little "bling".

Having KNOX doesn't mean the bootloader is locked. The M919 on 4.3 and above has KNOX implemented but the bootloader is still unlocked regardless of what baseband version you're on. Literally the only functional difference is that pre-MK2 firmware you can't trip the KNOX counter as it hadn't yet been implemented..

I've seen a lot of people mention that ROM, I'll definitely take a look once I get my device up and running (damn T-Mo store gave me a SIM card that had already been activated so I have a fancy paperweight until they can release the number so that I can activate it).
Out of curiosity, this the root method you'd recommend (I have a M919UVUEMK2 baseband)? Also, is there a way to flash CWM via ODIN? I'd rather not have to set my device up in order to install ROM Manager just to flash a recovery (I'm basically wanting to root, flash CWM, make a full backup, and then wipe and install a ROM).

Yes that will work. I recommend TWRP recovery. It works very well on our device. Here is the CWM Odin flasable .tar the download link is in post #24. If you like to give twrp a try just let me know. Also if you wanna try Insane KitKat let me know. I'm very familiar with it.

Awesome, thanks ... I vaguely remember TWRP from when it first came out but, it never made it to my old device; I'm probably going to go with CWM for the time being as I'm more familiar with it and I'm already a bit over my head trying to figure out the Samsung way of doing things. Really though, I'm hoping MadMaxx hurries up and releases his updated 4ext which is supposed to support this device.

Hey, sorry to bug you again but, since we're using the same device, on the same network, think you could answer this question for me (there doesn't seem to be a lot of traffic on that thread these days, and I'd rather not start my own thread with the same question).
