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.

I was wondering if a new method to install the last OTA was out. I didnt feel comfortable doing the methods I saw before. Like doing a backup then going stock then reinstalling root. Im hoping there is a apk file and only needing to install that and be done. I looked and couldnt find anything but that is probably my fault. Lol

Easiest way is to download the firmware from here http://forum.xda-developers.com/showthread.php?p=43418277 then download the app mobile odin from the play store. Then use the app to flash the tar file and then you are on the mf9 baseband and firmware. Then flash the mf9 rom and you have the entire OTA update.

Seriously? If you are rooted. Just flash mf9 stock rooted ROM.

Like windows, the best way is to do a full install and not an upgrade. Use PC Odin to flash the official full mf9 md5 tar. Reroot it. PC Odin seems to do a more thorough job than mobile Odin pro app. IMO, back up everything then do a full flash. The file is like 2.2gb. Yes that patch upgrade might work but you will have better performance and less problems if you do a full install tar.md5. I haven't messed with the full zip cwm flash, so I can't vouch for it. I have done what I explained and noticed better performance than just taking the update file. Yes it's more work but I, and a few other people, agree it's worth the extra time spent. Titanium backup can help speed things up, but doing the full job is better IMO.

Flashing the rom does not give you the modem/firmware.

Bet he was referring to this method or similar: http://forum.xda-developers.com/showthread.php?t=2357471
Which IMO the steps listed by crawrj in post #2 is still the easiest/fastest way to get to stock rooted MF9. But to each his own.
Yeah, I was ready on the mf9 rom, so just downloaded the firmware tar and used mobile odin for that. Haven't noticed any performance issues or anything, although I have nothing to compare it to other than different roms.

Ok. Here is what I have done and where I am at. First off I consider myself a noob. I am rooted with odex. I used the method from qbking77. My build was mdl on both lines under about phone. No issues there at all.
So last night I downloaded the MF9 zip file. Not the ones from craw. I used oden. I had to update the one file in note pad. I then put the MF9 file in the pda field on odin and installed. It installed and said passed. Now under about phone the build says MF9 and the other is mdl. No biggie there. Now the new rom is not taking. Im getting the stupid knox message and will delete that. My wifi is not working. I did read that a guy flashes the new rom and kernel and everything was fine. I go into twrp to flash the rom but cannot find it. I am assuming it starts off with mf9 in file name. This is where I need help and that help dumbed down for me. I just want the app to sd and the camera update.

To get WiFi to work you just need to.flash a new kernel. Go with agat or ktoonz. You need to be on MF9 based ROM to have the apps to SD and the camera update.
To update your baseband you need to flash the update modem zip. I'll try to get you a link.

I'm not entirely sure what you're asking here.
Sent from my SPH-L720 using xda premium
I've had bad luck with every custom kernel. Some, after flashing, the phone heats up and won't cool down. All of them seem to make my keyboard flip out.
For using Mobile Odin pro, it finished the flash much faster than PC Odin, so I wonder if it did everything properly. With my previous phone, e4gt, it wouldn't flash modems. I don't know if it works or not with this phone. I haven't tested. Tested meaning purposely flash a md5 with a different baseband to see if it actually changed it.
Let me see if I can say this better cause I am a noob. I am running odex rooted. Basically stock. I want MF9. I installed MF9 and it shows that under about device. Now when the phone boots it is still running 4.2. 4.3 is not running. When i finally got 4.3 to run all my apps and everything was gone. I freak out and installed a backup so now im back to 4.2. Now on 4.2 and 4.3 my wifi is not working. So what I need help with is getting 4.3 to run and my wifi to work.

What the heck are you talking about? 4.2.2 is the only software available for the Sprint S4. The MF9 update does not update your android version to 4.3. It is just a service update to touch wiz to improve performance and add some features. 4.3 android is a work in progress on our phones and not 100% functioning.

Sorry, I'm doing all this copy paste on the phone.
I was rooted on 4.3 and then I unrooted abd did it a update to nb1. Now when I try to use ISIS it says phone has been rooted. I know there is a work around but you have to be rooted for it. Is there a way I can remove whatever file ISIS is seeing that is making it think three phone is rooted when it's not.
Are you sure you're on NB1?If you're not, you will have to get pure stock 4.3 and flash via Odin

Yea I am on NB1, I was thinking of going back to MK2 doing a full unroot with removal of the backed up superuser. Then upgrading back to NB1. I will try it tonight to see if that will work.
You won't be able to downgrade to MK2

Post 2 has everything you need to root your devce and install a new Rom.
http://forum.xda-developers.com/showthread.php?t=2314494
If you want to just update and not care about rerooting ever again, you can download the stock rom and install it via odin. It will unroot your phone in the process.

Right. Just remember that you lose any advantages for rooting that MF3 has over MK2.
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]
The safest way is to flash full Odin nb1 stock located on post 2 of the following thread

this root seems alot more complicated than the one for MF3.
The direct root for NC1 is called towelroot. That thread also mentions this.

Turn on your OTA. Within one or two days AT&T will update your phone to 4.4.2 and NC1 firmware. Then you use towelroot .
If the OTA did not happen within two days, you might need to odin the stock MF3 then use the update software function to get OTA.
I turned in the ota and it downloaded the update but it won't update it. It keeps failing and it says my firmware in up to date and u have to wait 23 hours to do it again.

Sometimes, if you have rooted rom, it could happen.
Like I said, wait one or two days to see whether OTA successfully updated. If not you need to odin the stock MF3 to get OTA working..

So every time I want an OTA, I odin the stock rom.
