What do I do if I buy a 4.3 S4? will it be easy to root, unknox, etc? will I be gauranteed to lose warantee and not be able to return to factory conditions? All answers are appreciated, Thank you!

that guide was written before the 4.3 update, since then a knox counter has been implemented which cannot be reset and therefore will most likely void warranty...
Was just wondering if there is a way to avoid setting off that counter

Yes you're right about the Knox counter. Unfortunately there's no way to reset the counter right now. Beside those few things you can root and flash 4.3 custom Rom (cannot flash 4.2.2)

I guess my question is what if I buy a galaxy s4 with stock 4.3 updated via ota? When I root will I be automatically be stuck with a triggered knox counter or does rooting alone not affect the knox counter? Sorry for any misunderstanding.

As far as I know, rooting DOES trip the knox counter. If you can find one that's still on 4.2.2 (MDL or MDB) I'd go with that one. At least with one that's still on 4.2.2 you can reset the flash counter (knox counter is irrelevant on the m919 on pre-4.3 official) and still have the freedom to use 4.2.2 ROMs if you so desired.

I have stock 4.3 on my sgh t889

Try this post, easiest way is option 2, after installation, try to update SuperSU from Play Store and you can disable Knox when it asked.

Please keep in mind that if you already have the factory 4.3 update you already have KNOX. If you root you flash custom firmware onto your device you will hit your KNOX warranty counter and at this time there is no way to reset it. Just looking out for you since I did not do enough research before updating and am stuck with no warranty. Good luck.

i already tripped my knox.

Sad day man. I tripped mine yesterday knowing what would happen. I just couldn't stand having stock firmware anymore. Running SlimKat now and loving it. Hopefully our wonderful devs figure out how to get past this.

The sad thing about Knox tripping is that it actually diminishes functionality.
The old flash counter that was there before merely told Samsung that you have been messing with the device. Tripping the Knox counter removes potential functionality from the device. If at some point in the future you do need it, you are out of luck.
I understand the rationale behind doing it that way. It doesn't mean I have to like it...
Hastily spouted for your befuddlement

Knox is nothing more than Sammys new way of saying you unlock its yours but your warranty is gone. I hope the great minds here on xda figure out a way to reset the knox counter but Sammy obviously threw a ton of resources into this.

So I assume that Knox is part of the new bootloader? And replaces the old flash counter?

Hey guys.. I need some help returning my galaxy s4 to stock from CM 11

I was pretty stupid since I figured out how to install but can't get rid of it. I don't really like cyanogenmod so if someone can teach me how to go back to stock, I'll be really grateful and happy! Its m919 T-Mobile! TY

Hey buddy, I have the same phone as you and I needed up doing pretty much the same thing as you did. So if you want to get it back to stock, you're going to need odin. A stock image, which was provided by a awesome user named Vigz for me, and you need to reflash it. If you KNOX on you phone before flashing/rooting then you're counter is now 0x1 (no known cure yet) and you're warranty recover is next to impossible atm. But here's what xda helped me with so please use the info that I got to hopefully help you. Best of luck.

If you were on the official 4.3 firmware you have Knox.
(OTA, Kies or Odin flash the 4.3 firmware week give you the mk2 bootloader with built in Knox counter).

Sadly what the above comment said is true. You have KNOX. and you have tripped the counter/voided your warranty. There's no known counter (As far as I know of).

Another 4.3 bootloader question...sorry

I just want to be absolutely sure, so here goes. I am on stock, rooted 4.1.1 at the moment. If I just let AT&T run the 4.3 update, I can still keep/reroot root, I just can't go back to 4.1.1 correct?

Yeah, that's correct. If you go stock 4.3, via the OTA update, you will lose root initially. You can, however, always re-root. The most effective method to root after 4.3 is to Odin TWRP, boot to recovery and then flash SuperSu and the knox remover tool via recovery. Install SuperSU from the play store and run it to update the binary when prompted.

Won't let me thank you on the mobile app, so I'll do it when I get home from work, thank you! Wonder what happened to the premium version I paid for. Took my money and ran lol

Installing the OTA 4.3 update will also install Knox. Rooting will trip the Knox counter which will void your warranty. If you have no warranty left, tripping knox will now be a problem.
You should also know that Knox can sometimes interfere with obtaining root.

So one person saying you can root no problem, another one saying you might be able to root, might not? This is why there should be a very clear sticky at the top of the forums for everyone to read about just 4.3 and all there is to know about it. Because maybe's are pretty terrible when it comes to flashing/unlocking/rooting/bricking your device.
I don't care about warranty, I'm getting the S5 shortly, I just want to be able to root after the update, is that possible with lets just say the Auto root program, or is it not possible? By possible, I mean I won't have to go out and trade 7 cows for a horse and plow a 600 acre field with said horse.
EDIT: I think I've fingered it out, Thanks for the help fellas.

There is no question about it. You can root even after 4.3 OTA. I've done it half a dozen times. Audit is right that you will trip the warranty but since this isn't an issue ...
The usual methods of rooting including CF Auto-Root don't always work and the method I've used with success each time is Option 2 in the thread below. The knox removal script disables knox ...

Root is easy so long as you don't mind breaking the warranty.
Quick & easy, for the P600 model:

Thank you, however, I have knox installed.
Would I be able to go back to official firmware and unroot?.
Plus how do Samsung know you rooted your tablet?.

There is a knox counter which, when stock is 0X0. When rooted, the counter is tripped and goes to 0X1. There is no way to undo this and samsung will know.
You can always go back to stock by flashing stock firmware at anytime

Ah a fellow Uker.
I be tempted to root only so I can have apps like Sketchbook in window mode, however, since I just brought it I probably not bother yet.
