Unroot AT&T S4 with MF3 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I am trying to unroot my AT&T Galaxy S4 back to stock so I can apply the OTA updates. Currently I am rooted and running MF3 and cannot apply any of the OTA updates, fails at 25%
So if I want to unroot do I Odin the MF3 tar files or would it be better to Odin back to the MDL version? Then I should be able to apply the updates?

Why don't you just Odin the nb1 tar files and forget the ota?

I thought about doing that but was not sure if it was possible since since I was rooted. Was afraid of bricking the phone. So if I Odin NB1, how do I unroot the phone? Do I need to do anything before flashing that tar file?

Just flash in Odin. It'll put the new firmware on and remove root. You don't have to unroot first

Possible to unroot mf3 to update to 4.3?

Basically looking to go back to default factory settings, don't have the stock recovery anymore or a custom one, do not see if there's a official firmware that I can run
Would anyone be able to direct me in the right direction
Thanks
So your recovery is gone? Same thing happened to me before. Unfreeze any apps (if you froze any) take your phone to Best Buy and say Kies broke your phone. They can re-flash your phone which will unroot it and you get your recovery back. Then install the update.

Yes use the MF3 files in Odin and if you like root than re root and install Supersu pro to use survival mode and take the OTA Update and it will keep root for you . completely safe

I used the MF3 Odin files to Flash back to stock MF3 and re rooted to use Supersu survival mode and I took the OTA Update .safest way to root MK2. It can in fact be done

Want to restore to stock MF3 without Odin

I'm currently on MF3 but stupidly I deleted at&t apps and bloatware which means I can't update update to 4.4.2. I want to know if there's anyway that I can restore stock MF3 without Odin. I don't have access to a computer
anyone?

New firmware for SGHI337

I have an unlocked SGH - I337UCUAMDL running on 4.2.2. I tried updating it OTA but it failed. I am assuming it was because it is unlocked.
Is there an alternate version of this that I can download and flash through Odin?

If you have mdl why do you want to upgrade the firmware? You currently can use twrp and flash roms based on 4.4.2. If you upgrade with Odin or ota you'll lose that ability for ever.

In that case, look in the general forum for the nb1 Odin flashable tar file and flash that in Odin. You can then ota up from there.

1. Rootable is just that, you'll be able to root it using towelroot. The normal nb1 is not rootable. The nc1 firmware is rootable with towel root too. So you could flash the non-rootable, then ota to nc1 and root it
2. If you're sim unlocked flash with Odin will not lock it.

[Q] i337 4.4.4 Rooted. How to Unroot and return to factory

I saw a thread on how to unroot s4 on 4.4.4, but I can't find it anywhere. It's my wife's phone so I just want it to be returned to stock if possible so she can update to any new updates that come out soon. I used the odin towelroot method to root. I'm using safestrap as well. Any help would be great

Flash the nb1 tar file in Odin. Back up first off the internal sd card. http://forum.xda-developers.com/showthread.php?p=56453100
