Unroot NC1 AT&T 4.4 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Alright, as many know, we can root our phones with this method ( http://forum.xda-developers.com/showthread.php?t=2730144). Of course, I used the third post and everything is running fine and dandy. No problems at all. My question is, is there a possible unroot method for this specific occasion? If not at the moment, please post here when found. Thanks. [emoji106]

Unroot

Is it possible to fully unroot to back to mf3 stock so I can update to 4.3? I have looked everywhere. I need to know A.S.A.P
Yes. If you use the files in this thread http://forum.xda-developers.com/showthread.php?t=2502003 it will restore you to stock (unrooted) 4.2.2 MF3. Then you can run the OTA update to 4.3. That was what finally worked for me after trying everything else. (I was running rooted MF3.)
Do I download the files in the first link? And where are the instructions?
You need odin 3.07 and the mf3 tar files.

I just read in a different thread that if rooter mf3 owners revert to stock and run the official update than said owner will not be able to root. The actual words used were "permanently unrooted" this is a loose term, perm until proven otherwise. Based on this, make sure you understand this.

I remember reading about a root method for 4.3. I'll see if I can find the link.
Edit: It seems as though I was mistaken.

HORiZON I recall the same but the possible method I saw was the questionable method from recent verizon update.

[Q] AT&T Galaxy S4 4.3 Build Ending with MK2

Hi there,
Sorry, I am new to XDA.
Is there a root available for AT&T Samsung Galaxy S4 i337 which have been upgraded to 4.3 OTA. The build number ends with MK2 ?
I have looked at other threads but can't seem to find one of those straight forward tutorials for 4.3
Can anyone guide me in the right direction. Thanks.

somone can correct me if i'm wrong, but i dont think there is a safe way to do it right now. There is only vroot kingo, which are both unsafe as one pulls your binaries from your computer and the other pulls your IMEI and sends it to the china server.

Yes there is. I just Rooted mine yesterday. Go to kingoapp.com and download ver. 1.1.5.1792. I had to run through it twice, but now I can utilize the apps I couldn't before, like SuperUser & AdBlock.

Mal-Ware exists on vRoot, not KingoApp. It's clean and I have root.
So if i root with kingo will i be able to flash a rom? or does at&t have a locked bootloader?

Please follow this link. Kingo, vroot etc. aren't worth the worry. This method is fast and efficient. Anyone who tells you root isn't worth it doesn't know what they are talking about. At the very least you can delete the bloatware!

Question on how to update from rooted MF3 to MK2

I need help with updating my Galaxy S4. I tried the search but still confused.
I have rooted Galaxy S4 with MF3 and want to update to MK2 but since my phone is rooted with custom recovery (TWRP), I am not able to update OTA. What is the best way to update my phone to MK2 and root it again?
Sent from my SM-N900V using Xparent BlueTapatalk 2
I used the Odin mf3 tar files to go completely back to stock then flashed the mk2 update.img found in the att general section. Make sure you use it in the stock recovery...volume up when booting to get there. Then you can use safe root to get root back. Pretty easy actually. All posts are in the general thread. First page.

I have a similar question: I just bought S4 I337 on Ebay, and it has 4.2.2 (MF3) firmware, and SuperSU installed. I have root access. OTA software update from AT&T fails at 25%.
Does root access prevent the update? I tried "disabling and hiding" Superuser option in SuperSU settings, but it didn't help.
I'm getting ready to try permanent unroot, please let me know if there are any other options.

There is a way to keep root but I'm not sure how to do it. I think it's enable survival mode and uninstall root. But yes, root access will prevent ota. The mk2 safe root is incredibly easy and safe. Just need a computer. A lot better than the damn sd card 4.2 root.

I need the run down

I'm a tad confused as to how I'm supposed to go from mf3 to kit Kat while keeping root. If anyone could help out it would be great. I'd also like to know if staying on mf3 BL is better incase the bootloader is exploited again. Or is the work being done on current BLs.

Your best bet is to go to MK2. Work is taking place across different bootloaders, but a good amount of work is on MK2 including Hashcode's kexec exploit which functions on the root method for MK2 that allows the kernel memory to be modified. You can sideload the MK2 OTA or just flash the ODIN files if you don't mind wiping the internal data/storage. Once that's done, install Safestrap, and using the different guides you can either go to KeepRoot OTA to put yourself on the stock system with root or flash any 4.4.2 TouchWiz ROM with the KitKat Magic Toolkit.
Links? I'm searching but would appreciate the help.

●●Since you did it, what ROM you use?
I have tested all the Roms given in the all things att thread (link given earlier) and all of them work. I am now using black box 3.0 for its AOSP look and feel.

Since you have MF3, you have a locked bootloader and so lot of things are restricted. We do not have a direct root method for kitkat and so the only go is to install a pre-rooted kitkat rom.
Your best bet is to odin flash MK2, root, install safestrap and use the kitkat magic tool to install a kitkat rom.
Using Odin is simple.
Run odin in admin mode (right click and select "run as administrator")
Under options, only "Auto Reboot" and "F.Reset Time" should be selected.
Click on "BL" button and select the "BL_I337UCUEMK2_1921628_REV06_user_low_ship_MULTI_CERT.tar.md5" file from the MK2 extract.
Do the same for AP, CP and CSC
Put the phone in download mode
"adb reboot download" or
power-off the phone and press power, home and volume down buttons together. Hold it till you get the warning screen where you have to press volume up key.
Connect it to the computer. Odin should recognize and you should see an "Added!!" message in odin.
Hit the start button.
You should now have a clean stock MK2 firmware. Remember that this will wipe all your data.
Root: Use saferoot to root.
Safestrap: Install Safestrap v3.72 APK. Open the app and select install recovery.
Note: Safestrap is a special recovery that is available during the normal boot process. The stock recovery is still available and can be entered by pressing home and volume up when powering up the phone.
Entering safestrap recovery: Reboot the phone and when you see the safestrap screen, press the capacitive menu button (touch screen doesnt work).
Follow Kitkat magic tool and install the choice your rom from the All things AT&T MK2 and NB1 thread.

So you can use Black Box 3.0 on your AT&T i337? I saw on the list that it says "XXUFNB8 -- i9505" and figured that it would be risky to run it on my i337. Are there any extra steps that you have to take to get it to work?
I haven't made the jump from mf3 yet but Black Box 3 is looking pretty tempting.
Error
So I downloaded the MK2 AIO Tar file and then placed each file into their respective slots.
I keep encountering this error:
Invalid Percent of Drawing download progress bar!
Now this is happening every single time I use Odin 3 V 3.09.
I am redownloading the MK2 files and instead picking the download with the 4 separate players.
Hopefully this is resolved with the new download but if you guys have any suggestions lets me know.
Trying again now with the multiple file version. Seems to be working like a charm.

Any ROM listed in the All things AT&T MK2 and NB1 thread will work on ATT I337. The thread is for this phone.
You have to first upgrade to MK2 by flashing the full odin image from the thread and then use KitKat magic tool to install kitkat Roms.
Wifi isn't working. I flashed the mk2 modules but Nada. Do I need nc1 modules and if so where do I download it.

[Q] Any way to root AT&T S4 on NC1 4.4?

Missed android so I traded my iPhone 5 for an S4. It was already updated and on NC1. Need root for an app that I use at work a lot through the day. Can someone either guide me step-by-step or give me the links to do it? Thanks in advance.
Look in the general forum for index, all things mk2, nb1. Treat nc1 just like nb1. You'll have to down grade, install safestrap and then flash a rooted rom.
