How do I unroot when on stock (rooted) 4.3 firmware?

I am on firmware 4.3 that I rooted a while ago. I would like to unroot 4.3 however I cannot figure out how. I thought I could flash stock 4.3 via Odin but there are no .tar versions of 4.3. Help?

Do you have the full stock version of 4.3 or the modified (unrooted) version? You can check your phone's settings and build number to see if it's MJB or MJ2. You can try unrooting from the SuperSU app. The definitive solution to unrooting is indeed to flash a complete stock image. An Odin flashable *.tar file was recently developed. There have, however, been reports on outcome. You can flash custom recovery to your phone (either of CWM or TWRP) and use the instructions in the thread below to download and flash a complete stock restore.

[Q]Need clarification for rooted rogers note 2, android 4.4

Hello, I recently just updated my Rogers SGH-i317M to 4.3, which then downloaded a system update which put it at 4.4. I was running Jedi X20, which is based on 4.1.2, when I first tried updating, I flashed the "4.3param_tz" file in odin, and was left with an error screen saying I need to recover using Kies, so I downloaded the official release, flashed via odin, and thats how I got to where I am now. I want to try the "Ditto Note 3" rom, "Sky Note Air 4.3", "Mean Bean" and "Beanstalk". My main question is, can I just start flashing these roms like I was before on 4.1.2, or do I need to use the specific kernel listed on their page? Before you needed a specific kernel to run a touchwiz rom or an aosp rom, so is it still the same? Or can I use my stock 4.4 kernel and try both aosp and tw roms now? If so could you point out the kernels I would need? And educate me on anything else I should know about before flashing 4.3 and 4.4 roms, (I'm not worried about warranty), this would be greatly appreciated. Thanks for your time in reading this and helping me out, much appreciated!!

Regardless of where u are, I'd Odin to Rogers stock KK 4.4.2. Then Odin Twrp recovery, boot into twrp recovery and flash SU v.1.99. Finally choose your rom and flash away. This way you are on the lastest KK 4.4.2 Bootloader and KK Modem/Baseband.

I did all that except flash SU 1.99, so I tried flashing SKynote Air and it didnt work, upon restarting my phone it said no os is available. So I tried restoring from the backup I made of the official 4.4.2 Samsung rom in twrp, didn't work. Tried Odin, didn't work. Then I tried flashing the Skynote rom again and it worked. So I'm afraid of flashing any other roms now.

Downgrading from 4.4.x to 4.3

I was wondering if I may run into any problems by doing this.
I know that on an AT&T phone (i747), if you do that, you may lose your modem and needs to be reflashed (you get a null IMEI)
Is it the same on a SGH-T999? I was planning to flash this ROM:

Thanks

There is no 4.4.2 to downgrade from for the T999.
If you just have a 4.4.2 Rom, you don't need to do anything.
The firmware you linked is the latest available so you can flash it regardless of what you have now.

There is no 4.4.2 update for the T999 so yes you can flash it but it is not a ROM, it is firmware, please do not confuse these two they are very different!

Yeah... I'm afraid I am confused. What I did was to flash this:
http://forum.xda-developers.com/showthread.php?t=2690947
Isn't that a ROM?
However I would like to go back to 4.3, so I was just wondering if I could have any problems.
Sorry for the noob questions. I think it was clear to me, but I'm afraid it's not...
Thanks

Yes that is a rom, what you linked to in the first post is firmware which contains more than just the system and that is where you run into problems when downgrading

So if I'm on 4.4.4 right now, is there a way to go back to 4.3?

Yes, flash the link you provided in the first post or flash a 4.3 rom.. Understand this, flashing a rom will not determine if you can downgrade or not, flashing firmware will. Since there is no 4.4 firmware for the T999 you can still flash the 4.3 firmware. If there was a 4.4 firmware and you took the OTA or updated via Odin then the only thing you could do is flash a 4.3 rom, firmware will not be an option
Edit: oh and btw I accidently pressed the thanks button so you got a free one

Thanks. I understand better now. I have always been kind of confused between ROMs and firmwares.
PS: I triple thanked you.

upgrade from

Recently brought my GS3 I747M back to life from a hard brick... and I flashed it to stock 4.0.4 rom via odin when doing so.Would I be able to upgrade it directly to stock 4.4.2 using odin? Or do I need to upgrade it to earlier version first, like 4.1 and 4.3? (phone is already rooted, so cant do it thru OTA). Thanks!

You can flash it with odin, but will need to factory reset too.

sure worked, thanks!

How To Update and Root to 4.4.4

Hi, sorry this is probably a noob question but I've been reading through the forums and got confused how to update my rooted s4. Normally I would just install the custom rom with the update but it seems like this isnt the case right now.
I'm currently on 4.2.2, rooted, and have wicked as my rom. How would I update to 4.4.4? From what I understand there is a new modem and firmware... something to do with NH7? Can someone explain to me what NH7 does. Thanks for all your help!

NH7 is the newest firmware based on 4.4.4 and it is recommended if you plan of using 4.4.4 tw roms. To update it just download the NH7 firmware from general thread and flash it with Odin, after that you can use cf-auto root to root, or if you're just planning to flash a ROM then just flash recovery and then flash ROM.. If you care about tripping your Knox counter then just know that flashing recovery or rooting will trip it

You mention that you want to update and that under normal circumstances you would simply flash the an updated custom ROM... yet you say you've read it isn't that simple, right?
You are correct, it isn't THAT simple, but it is ALMOST that simple. Being as that you are still on the old 4.2.2 pre-KNOX bootloader and all, you can flash and flash and flash all day long and a single use of Triangle Away is all you'd need to still be able to revert your device back to 100% stock, both firmware AND flash counters if you ever needed to for some reason. If you use Odin, Kies, or take an OTA update you will lose that ability. Anything you flash once you go through official channels to update will trip your KNOX counter... and that cannot be reset. The problems you've read about simply flashing an updated custom ROM is that you will have problems with data.
The data drops can be avoided by flashing the newest modem, which would be NH7. Understand though, that method only updates your GSM modem; your LTE modem would be unaffected. This would only be a problem though if you are having trouble receiving LTE where others with the same carrier can get it with no problem. If you aren't having any problems with LTE, then I would recommend to simply update your GSM modem and use the custom recovery of your choice (ClockWorkMod, Philz Touch, or TWRP) to flash any of the ROMs in the T-Mobile GS4 Android Development section.
To update your GSM modem, follow the instructions in this thread. That thread is for updating to the 4.4.2 NB4 modem, which that modem would actually be all you need; but if you wish to have the NH7 modem, just use the modem.bin ONLY file from this post instead of the modem package included in the tutorial thread. After that little bit of work, you can flash any Android version you want; from 4.2.2 all the way up to 4.4.4... AOSP, TouchWiz, or the Google Play Edition ROMs.

So from what I understand...
1. Update the modem not firmware
2. Flash ROM
So I don't need to re-root?

You are correct.
No need to re-root.
