For using towelroot, flash any version of 4.4.2 lower than the XXUGNG8 which does not have KNOX 2.0
Then towelroot

Haha yes buddy..INDEED!
But ONLY ORIGINAL SAMSUNG STOCK FIRMWARES and custom RECOVERIES.
If you need to flash any custom roms, flash via custom recovery. Not all custom roms are odin compatable.

[Q] Unroot Galaxy S4 (i9505) from Omega Rom

Hello.
Thankfully before some months i bought my S4 and I rooted to Omega rom with your help.
Now I am sick of it and I want to sell the mobile.
How will I restore to completely default system so the warranty from Samsung is back?

on my i9056 i flashed 4.4.2 stock from 4.3 rooted by towelroot throught ODIN and i have KNOX intact now :good:
Official firmwares never trip knox.
It is always safe to flash the OFFICIAL firmware.

Why unroot again and again if you have to flash a stock rom?
Just flash a stock rom and youre unrooted
But remember. Knox 2.0 wont let you use towelroot.

If knox 2.0 is in 4.4.2 then how can you avoid it when updating to 4.4.2?

Knox 2.0 is not in 4.4.2 it is an update that rolled out a few weeks ago.
Not sure if once in 2.0 it can be downgraded by flashing a previous 4.4.2 rom.
It has many new updates like the pattern lock and simplified method of transfer of data from our phone to the knox containers.
It looks like this now

I've only updated to 4.4.2, never updated or run knox-i have the app disabled-but it's listed as being 2.0.0 in Manage Apps, with no updates to uninstall as I've not updated it., yet it's still already 2.0.

Well i call it knox 2.0 because when i had a 100mb upgrade, it stated that your phone is going to upgrade to 2.0 with a kids mode functionality.
Rest even I have never noticed the version no. Just many UI changes from knox 1.0 to 2.0.
Plus Even samsung calls it 2.0. It was stated on the samsung's website that it knew about towel root exploiting the linux kernel and it shall resolve this in an update.
Rest idk what that update was. I clearly remember samsung calling it knox 2.0 upgrade update.

So you had a 100mb non-4.4.2 update? I'm sure you mean knox 2.0 was in the ota for 4.4.2, which I think can be rooted. Are you sure 2.0 can't be towelrooted?

Well yes. I am already on 4.4.2. Received the uodate 2 days back.
PURELY KNOX 2.0 update.
Well many people,including my sister did that upgrade and towelroot stopped rooting. And many are complaining now that towelroot has stopped working.
That is why I blame the update.
I cannot use towelroot altogether as it does not work on i9500.

Brilliant, thanks. I've been on xxugne8 4.4.2 build date May 21st since I got this phone in the uk about 2 weeks ago but can't find it listed on sam, perhaps I just had an early update? I guess no way to root without typing knox on post-june kernels as towelroot now @google :/

Well maybe. Because samsung was keen on stopping towelroot anyhow. They patched the linux kernels.

ok, so:
upgrade to 4.4.2 with Odin will update it without tripping KNOX, just no to upgrade KNOX to 2.0 when receive this update, and the towelroot will work.
If necessary, for warranty reasons, re-install 4.4.2 with Odin will unroot it and have stock ROM as brand new.
Correct?

What exactly do you want mate?
If you flash the official firmware agaim you'll be able to upgrade your phone via kies or get OTA updates.
If you install a custom rom, you wont be able to get anything and in addition burn the knox efuse.
Plus we, at XDA wont recommend you one. You have to search for yourself which rom fits your requirements the best. Each rom has something unique.
Check the developers thread, read about the bugs and fixes and then we think you are wise enough to decide on your own

Download the official firmware from sammobile.com for your model no.
Flash it via odin
Youre done
But you will loose root access. For that, use towelroot. ^_^

Does towelroot set the device software flash to custom preventing future otas?

[Q] So I just bought my S4..

Hi everyone. I just bought my SGS4 today (i9505) and I want to know how to proceed before messing around. I searched a lot on the forums and on the internet but I can't figure out what to do.
I'm currently on 4.2.2 and I'd like to flash a custom rom without voiding the knox counter. How should I do?
Thanks in advance

Ok so.. Before rooting with Towelroot, should I upgrade to the latest available firmware? Also, once I want to go back to stock, how should I do?

Sry I've read you are on Version 4.4.2. My mistake.
So you currently run Android 4.2.2. Do you have the Knox bootloader already? It is inverted to all firmware builds MGG or higher.
When you don't have the Knox bootloader you can flash everything you want to and you are still able to reset the counter with triangle away.
When you are on the new Knox bootloader i would recommend you to upgrade to the latest Android version and then use the link I posted.

My build version ends with UDMGG so I believe I have knox. Before updating.. is it possible to revert to stock (for warranty pourposes) with the method you linked me?

You can mess around by safely using custom roms without tripping knox to.
The i9505 supports that too.

Just flash stock rom via and youre done.
But remember once knox is tripped (0x1) you cannot make it okay.
That is why I said you can safely "mess around" with your i9505 by flashing custom roms without tripping knox.

Thank you sir.. Just to clarify: I could use the same method to flash the stock image? If this is correct, could you provide a link to these stock images?
Sorry for being such hesitant, but I don't want to screw up with my warranty. At least, not yet.
