Upgrading to 4.3 without triggering the KNOX void warranty

Hi,
I'm using a rooted N7100 with a stock rom (4.1). Is there any way to upgrade to 4.3 without voiding the warranty?
thanks!

you can simply flash the leaked stock 4.3 version via odin, It wont void your warranty.

Do not install official 4.3 unless you wont plan to use any custom rom or downgrade to an earlier version of android!
You'll have knox active on 4.3

I'm sorry. what?
Will you elaborate a bit?
I already installed 4.3. How will knox affect my warranty?

You apparently didn't do any reading first.. Really?
Can I flash custom recovery/kernel/rom without tripping KNOX flags?
No, Flashing a custom ROM will trip the flag
No, Flashing a custom Kernel will trip the flag
No, Flashing a custom Recovery will trip the flag
You can root it however without tripping the Knox flag.

I am using stock rom with root with Untripped Knox flag. No custom rom or kernel. You should check out the different rom and other threads to find out what they offer and what people who have tried them are saying.
Very much up to someones opinion as to what is good or not.

Ok, but pls can you tell me how you rooted yours without tripping the knox flag. Because I read somewhere the kingo isn't safe, that it collects IMEI numbers and serials

I did mine a long time ago using Root De La Vega.... If I had to do it now, I would most likely use Kingoroot. Yes their process did collect IMEI's at the beginning but they are apparently not doing that now.

Root MJ9 without triggering KNOX

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.

[Q/A] Answers Added - OTA's/Updates, rooting & tripping Knox? - other questions

So I rooted using chainfires method for my Tab S 8.4 wifi (T700) and it tripped Knox (0x1). I know there is no way to currently reset it and there is a bounty out for it. No big deal on tripping it, I wanted to root anyways and want to try out CM12 eventually. After doing some research it appears Knox gets tripped when unofficial firmware or recoveries get flashed via Odin. Knox is not tripped when you flash official Samsung firmware. I had a few questions though I can't seem to get a clear answer on and was hoping to find some or get a discussion going at least about Knox for the Tab S.
Questions and Answers
- Are you still able to receive OTA updates on a stock rooted rom/recovery with Knox tripped?
A: No, not while rooted, "Operating System on your device has been modified in an unauthorized way. Try downloading software updates using Samsung Kies on your PC" Unsure if Knox prevents it but most likely does not.
- Will you lose root if you can get OTA updates?
A: No OTA Updates allowed on rooted devices. Reports have stated that flashing the official firmware update via odin will unroot the device but maintain data, most likely kies is the same when updating. However if a bootloop occurs after flashing, you may need to wipe data and cache via stock recovery.
- If knox is tripped (0x1), if I flash a custom recovery (TWRP/CWM) or use chainfires method to root again will it trip Knox again (0x2)?
A: YES & NO, Knox will not read (0x2) if unofficial img's are flashed via Odin but reports on other devices have stated it will read {0x1(2)}
- If yes can you trip Knox too many times, rendering device inoperable or bricked?
A: NO, tripping Knox only informs if warranty has been voided by flashing unofficial firmware/recovery/img files and root kernals via Odin. When the knox warranty void status is tripped, the knox software will no longer work.
- What is tripped specifically in Knox (for the Galaxy Tab S), an efuse, or is it software or binary code?
A: Most likely an eFuse. There is no way to reset the flag counter as it is believed to be an eFuse that once gets blown it stays damaged and cannot be reset.
***New Questions***
- Will flashing a custom recovery img (TWRP/CWM) via ADB trip Knox (0x1)?
A: Yes, it will trip Knox.
Thanks to all who answer and contribute.
If there are any new questions, updates to be added or wrong information to be corrected please let me know.

No OTAs when you are rooted on custom rom. Dont worry, someone will make a stock custom rom to flash with twrp Or you can odin flash stock lollipop and root with twrp
If you do the ota it will probably not install because of root.
If you flash a custom recovery, or root again.. Knox will stay 0x1. It wont change.
Knox is like a check when booting up your device. Its more like uhh protection. If you install custom stuff then you dont get protection. Knox was a security feature that samsung included. Its really not needed as it really doesnt work. Thats why people trip it. I highly doubt its used for security but I think its just used to detect if warranty has been void or not. Its not something that you should worry.
Hope this helps!

Thanks, I figured Knox is nothing more than just a feature to let Tech's know if the warranty had been voided. Also I figure that flashing the updates myself when they come out would be the best option. Thanks again.

how do you make the knoxx counter back to zero ??

Read post two above yours. It can not be reset to zero once it's tripped.

Even if you root and trip knox, although you cannot receive official ota's, you can still use samsung kies to still recieve the updates.

updated OP with answers to questions.

Stupid Knox. This is one "feature" of Samsung devices which makes me less likely to purchase them in the future.

For the new question, flashing any custom recovery with odin or adb will trip knox. Flashing stock should not trip
