My wife's S3 got the OTA before I had heard of the Knox problem.
Her phone has some major issues after the update & I am trying to find a way to fix it.
I flashed the MK3 all in one ordered Rom posted by Thunder Stick on my S3 & it seems great so far.
My question is: since she already has Knox on her phone, can I put CWM or PhilZ on her's so I can flash the same rom I put on my phone, or will this cause Knox issues? I'm not worried about the warranty counter, just worried about bricking it.
Any input is welcomed.
Thanks y'all

I have read that a few times already. I think what I am unclear on is about the difference between the boot loader & recovery. I was thinking that CWM would replace the boot loader & that is what I was worried about. So, if I have it straight now, the CWM & flashable Rom of MK3 will not replace the boot loader? You need a tar to do the bootloader? So will it matter if the rom has had Knox taken out or should I look for one with knox? I was hoping to use the All In One Rom, but it has no Knox.
Sorry to be a pest guys

CWM will replace the stock Android recovery. Yes, a tar file can downgrade the bootloader. you can flash any ROM as long you do not downgrade the bootloader.
Thanks Joey
I've read a little bit about Knox in the last few months, but wanted to make sure I've got everything right, especially since things have probably changed since the early days of Knox.
Here's my situation: I'm running a TMO Galaxy S3 w/ stock recovery. I was using mrRobinson's T999UVDMD5 and foolishly did the TMO update to T999UVUEMJC.
(I thought I'd be able to retain root, but ended up losing root, getting Knox, and a bootloader that won't let me roll back. )
Now my phone locks up during boot. If I'm lucky, it'll boot but locks up nearly immediately after boot.
And this is with stock everything. I've had the phone a year and a half, so it's out of warranty.
So what's Sammy's stance on their update breaking phones out of warranty?
Do they cover that? Can I get a TMO store to put DMD5 back on?
I'm thinking of using the root66 EMJC img. I'm pretty confident that it won't brick the phone, since it'll be the same bootloader I'm currently running.
And I'm not too worried if it trips the Flash Counter (flag, really) since I should be able to clear it.
But what about the Knox counter? Will that get tripped? mrRobinson's post leads me to think that it will.
Any other root options I should consider? (Above all else, I'd like to be able to restore back to stock if I need to.)
I kinda like the stock ROM (save for some bloatware) and TouchWiz doesn't bother me.
If it's out of warranty, it shouldn't matter if you trip the Knox counter, Should it? Some say as long as you don't install a custom recovery that if you do the root 66 method just for root that Knox doesn't trip. But I can never get anyone to confirm that.

Thanks masondoctorjt! That's one of my questions. (albeit, a lesser one)
If TMO/Sammy's update f'd up my phone will they cover it if it's out of warranty? especially when it was fine before?
(It's also a work phone, so I'd like to be able to return it like I got it, if need be.)
It's that confirmation I'm looking for here.
This Knox thread seems to state that as long as a Knox-enabled bootloader is used, the counter won't trip. But it also says flashing Knox-enabled fw via Odin trips the Knox counter too. (which I don't fully believe) Hence my confusion. A lot of contradictory info.
Add to that the loose usage of 'flash counter' to refer to both the triangle/flash counter/flag and the Knox counter/flag and you can see why my head is spinning!
It was tricky for me to see the Knox Counter info for my phone. Recovery and Bootloader mode didn't pop up the screen.
But when I used adb to enter bootloader, I saw the counter info.
So did you root it, and if so, did the trip the knox counter?

No, not yet. I was hoping to hear back from someone who's tried this.
I didn't want to be the first guinea pig.
I'll probably take my phone down to the T-Mobile store this weekend and give them an earful to see if they can roll me back w/o tripping Knox flag and report back.

I honestly don't expect a whole lot from them really. But it's an avenue I have to try.
I'm ultimately going to root this anyway. If TMO can successfully roll me back to T999UVDMD5 completely, I'll just root that and stick till the dust has settled somewhat on Knox.
For Rooting after getting that 4.3 update, the process is pretty simple really. Since you have 4.3, you flash Root66 Via Odin. Or you could flash a custom Recovery via Odin and then flash SuperSU zip via Recovery.
It is my understanding that either one will not trip the Knox Counter. If you wish you can follow this guide.
NOTE - Do not Try to flash Older Root66 versions. You can only flash UVUEMJC version. If you flash any other version even accidentally then you will get expensive paperweight.

It was ultimately unproductive.
I went in and explained the situation (w/ less detail) and asked them to roll me back to UVDMD5.
They said Samsung doesn't let them roll back, so he then proceeded to recover my phone.
He booted into recovery and wiped cache. When that proved unsuccessful, he wiped data. (nothing I couldn't have done)
Wiping data ultimately made the phone usable again. He then proceeded to enter some short codes to bind me to the network quicker.
(all he mentioned was #NUM#)
So I'm back to stock (more or less ). Not sure when I'll root now.

From what I've read, the custom recovery should trip Knox. Have you tried this yourself?
I'm fairly confident if I merely flash root66 that it won't trip Knox. But I'd like better than a 51% confidence interval, that's all.
(Again, it's a work phone and I'd like to return it as I got it.)
It will trip that previous counter bit. Don't think it will trip the Knox counter.
No I do not have the Knox Counter.

I believe I tripped the Knox counter when I flashed CWM recovery after I flashed stock 4.3 from Docs signature. Phone works great but no warranty on a 6 month old phone.

Pat,
So just to get this straight, you flashed the stock TMO update, so you were not rooted?
Or did you do a root-injected variant of the stock?
Either way, I'm surprised you tripped the (triangle) flash counter.
But I'm more worried about the Knox counter; not worried about the other since there is Triangle Away.

I flashed T999LUVUBMK4 from Docs signature. I am not exactly sure when the flash counter tripped. I do know that the Knox bit was tripped by my flashing the recovery.
Edit: Don't remember how I got root. Sorry.
Edit2: T999L_4.3_UVUBMK4_deodexed_KnoxFREE.zip is the file I flashed.

The Flash Counter (Triangle away kind) will trip due to the running tracer (read Sysscope) in that Rom. I'd not worry about it as Triangle away will take care of it. Yes it trips due to custom Recovery and Root.

Thanks for that Perseus71. Didn't know about Sysscope before, but sounds interesting. I figured root66 removed it, since mrRobinson claims that it doesn't trip the normal flash counter. And this matches my experience w/ his previous root66.

So it sounds like you were able to flash a rooted ROM and not affect Knox, as long as you leave the stock recovery.
That was my plan anyway. I'll probably look into this later this week.

Yep. Let us know how it goes.
FYI, the Knox counter gets tripped.
I flashed the root66 T999UVUEMJC via Odin. That's it.
Oh, and the flash counter does not get set.
Hi everyone,
I sent my Note 2 for a repair through the warranty, and I just got it back updated to 4.3 with N7100XXUEMJ9. I found this thread:
http://forum.xda-developers.com/showthread.php?t=2500823
but from what I understand, it seems it can only work if I am on a lower version and then upgrade to MJ5 and root.
So what I am asking is, does anyone know how to root a Note2 already on MJ9 without triggering KNOX?
Or can I just downgrade to MJ5 and follow the thread instructions? although from what I read I cannot downgrade without triggering KNOX. right?

Thanks for answering.
I stumbled upon that thread before, but it's only for rooting. I guess there's no chance to flash a recovery and custom rom yet, is there?
Anyway, if I root as described, how can I unroot and more important, reset the counter to 0 and official if I need to return for the warranty?
Once you trigger KNOX warranty void, there is no ways currently to "reset" that status.

(Without voiding knox) She has a completly stock 4.4.2 tmobile s4. She wants to update to 4.4.4. While trying to reset with triangle away i noticed i couldnt boot her recovery. Download mode works fine though. So what can i do? Push a stock recovery to her phone? Factory reset within the phone? Odin the new offical firmware without voiding knox? Help!
Delete

Download stock 4.4.4 firmware and flash with Odin and recovery would probably be fixed.. Easy way to take care of both problems
We need more info. It would help if you could post a picture of your sister.
Wouldnt knox get flagged serio22? And hilarious ultra ha
So I renamed and pushed the stock recovery.img from NB4 and everyhing seems to be working and knox is still 0x0. Ha good stuff.
Ok so i just odin'd the NB4 firmware and everything worked and knox is fine. Ill just have her OTA NH7. Love how on google its a 50/50 on flashing official firmware. Well anyway thanks guys and hopefully this helps people with knox. Glad I dont have it haha p.s. NH7 modem seems alright on MDL....so far so good.
Yeah the only way Knox will trip is if you flash custom recovery or kernel
Thats what i figured but damn goohl got me mixed up. Thanks again

If you already have a bootloader with Knox, you can't downgrade.
MDL was the last bootloader without Knox. MK2, NB4 and NH7 all have Knox. You can download the free Samsung Phone Info app from the Play Store and it will tell which you have. Or, if you go into download mode and there is any line that says Knox, you have a bootloader with Knox. You can only re-flash the same version or newer, but the Knox flag won't go away. If it is tripped, it will stay tripped.
There have been reports that sometimes Samsung will check the Knox flag, but T-Mobile doesn't usually. YMMV.
