Use the rootable one in your case. See the other link I gave you also. You can't flash Twrp on your device. You'll need to use safestrap

Thanks a lot for this, it worked, what should i use for root now? i think im leaving the stock rom or i need to install another rom for rooting?

[Q] [Solved] TWRP Restore / I337UCUAMDL Odin Restore

Hello all
So I have been doing some flashing and I wanted to restore to the original stock ROM that I made a backup of (via TWRP) right after I rooted my device using the Casual tool in the dev forum but I had a question just to make sure I don't botch anything before I go for the restore:
I am coming from CleanROM 1.5 the MF3 based ROM -- I'm assuming the ROM didn't touch the bootloader
1) I performed an Odin recovery of the I337UCUAMDB baseband version of the OS (factory) from the Dev Forum
2) My original backup was of the I337UCUAMDL baseband version -- Am I able to perform a TWRP restore without causing any problems here?
3) Do I have do Loki-Doki after I restore?
I would try this myself but I really don't want to risk a hard brick in case this isn't the correct way - thanks for the advice in advance all.
An Alternative to this would be to obtain the Odin PDA file for the I337UCUAMDL baseband firmware which I have been unable to locate
Alright well I just went ahead with the restore and The baseband version stayed the same despite the fact that the backup was originally from the MDL baseband. Is there anywhere I can download the Odin file to flash the MDL firmware?
No one's helped me with my problem, so might as well help you out lol! Here's a link for MDL http://storagecow.eu/Xda/AT&T S4/St...s.com-SGH-I337-ATT-I337UCUAMDL-1367050591.zip Flash with Odin
I just did some digging around and actually found this awesome website and I am downloading the MDL right now
http://www.sammobile.com/firmwares/1/?model=SGH-I337&pcode=0#firmware
I do believe that this is legitimate - if not someone please correct me. Have 2 hours until the download is finished anyways lol

Thanks for the offer -- but as long as the steps are essentially the same as Adam's Factory Stock thread in Android Development then I should be alright! I'm assuming that is the case

Yes, Currently have the MDB installed and running, going to enter download mode and flash MDL via ODIN and basically my plan was to freeze the AT&T auto-update checker application - I have frozen it before and I'm guessing that is the first application in the chain that initiates the update. I'll keep ya posted the MDL is still downloading lol

I337 AT&T S4 - Return to Stock (No WiFi)

I recently bit off more than I could chew with my S4 (I337). I had 4.4.2 KitKat on it and wanted to root it to add teathering. I decided thought there was no root for 4.4.2 so I thought I would try downgrading to 4.3 then root. This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.
Had this issue before on my Bell Canada S4, but don't recall exact way to fix it.
Think the solution was to find an older (might be newer) stock. I think I used a different version like the Telus Canada version as well and it ended up working. Then you update through kies after.

Wifi does not work because of the modem/kernel mismatch, i.e. MDB modem and MK2 kernel. Not sure what your goal was when you began flashing your phone but since you fortunately did not flash teh MK2 bootloader you are still able to locate the MDB full odin tar and flash back to stock which will resolve your issue.

It depends on what you are trying to accomplish. Are you trying to upgrade to MK2 or higher while maintaining your unlocked MDB bootloader?

If you don't care about losing your MDB unlocked bootloader you can get to the latest kitkat firmware by flashing the NB1 full odin tar from here:
http://forum.xda-developers.com/showthread.php?t=2674223, then once flashing is complete go to settings/more/about phone/software update then take the ota update to NC1 which is the latest kitkat version for our phone.
But what I would do is keep your unlocked MDB bootloader and since you already flashed the MK2 AP file you can get your phone running well again by flashing the MK2 modem: https://mega.co.nz/#!pwESna5I!YK7EKG37xXIG1ReB-Z-mfSMoXNkXQ9t2EdMK9ofgJKg
From there, there are still a number of options available to get to kitkat which I won't get into.

excited to give this a try. rooted with the downgrade method a couple months ago but left with a non-wifi device. my only issue is that the thread says it's for I337UCUFNC1 and our devices are on jss15j.i337ucuemk2. will this fix still work? I've heard on other threads on the subject that the modem kernel doesn't match up with the flashed rom or build number or something.

Do you already fix it??? cause i have the same problem
Same question, different thread!
Not even an hour ago did I answer the same question in a different thread: How do I get WiFi working on my S4?
Well here you go.
My original answer: http://forum.xda-developers.com/gal...-4-4-2-nb1-t2850878/post54978150#post54978150
The problem is, in order to get WiFi working, you need to install the NB1 modules, but to do that, you need to install Safestrap. However, you can not install Safestrap because the app keeps closing on you. There is a simple fix to this, which I will explain later. For now, just read this WHOLE post BEFORE you do anything, and keep in mind that I am NOT held liable if you mess up your phone. Use this at your own risk.
1.) Root your phone
If you're already rooted with something like SuperSU or Superuser, skip this. If not, read ahead. Download and install the Towelroot APK file attached to this post, open it, and click 'make it ra1n'. If your phone didn't reboot, now you have root (they need to trademark that). Now, down below, I also included the APK for SuperSU. Download and install it. Now open it. When you open it, let it install the 'Normal' way, not via the 'TWRP/CWM' way. Also, when it asks you to disable KNOX, say yes, wait a couple of minutes (it will still be loading) and reboot your phone. Open up SuperSU again, click 'Yes' to disable KNOX again, and now you have a good base to start from.
2.) Install Safestrap AFTER fixing the error
The error your are getting is easily fixed. Go to the Play Store and install 'SELinux Mode Changer'. Open it, grant it root access, and change the mode to 'Permissive'. Now, open up Safestrap again (you mentioned you already installed it), and it shouldn't force close. Click 'Install', and if the 'Reboot to Recovery' option below is not grayed out after that then it worked.
3.) Download and install the NB1 modules
On your phone, download the included NB1 modules ZIP file I attached for you, and once that is done you need to reboot. After the Galaxy S4 logo, you'll see a screen that says 'SAFESTRAP: DISABLED' and there will be a little robot. TIP: To enter Safestrap, press the menu button (physical, hardware key) under 'Recovery' at that screen. To continue to Android, press the back key (again, physical) under the 'System' tab. For now, press the menu button under 'Recovery'. Now, click 'Install' which should be in red, click 'Add zips', and navigate to your Downloads folder. Now click on the NB1 modules ZIP you just downloaded. Swipe to install, and reboot. This time, hit the back key under 'System'.
All done!
Now, Android should (and will) boot up, and you'll have working WiFi! If, for some odd reason, you don't have WiFi- do NOT panic! Just search around for the MF3 modules and flash those! All is good, all is good. A lot of this guide was taken from my post about my personal method of SIM unlocking the AT&T Galaxy S4 without the dialer codes or an AT&T SIM. It was just modified a little to work for you.
Remember, hit thanks!

Those are my exact words. Also, the attached files (NB1 modules, SuperSU, Towelroot, etc.) can be found attached to my post in the link above. Have a good night, and best of luck! :good::good::good:

[Q] No Recovery Mode

I have an i337 NC1 build Galaxy S4 (AT&T). I'm totally new to custom roming, but I wanted to give it a shot for fun. I tried using towelroot along with SuperSu, and TWRP Manager to flash TWRP onto my phone because it supposedly worked on NC1. Apparently I did something wrong because I no longer have a recovery mode. It just gives the downloading/target screen when I try to access it. Am I screwed or is there some possible way for me to fix this? Thanks!

Also, using volume up or down to enter recovery mode?

You can't just install a recovery just like that because at&t has a locked bootloader. You will probably need something like safestrap.
Go to the proper forum for help.

That's a completely different problem. Sounds more like a hardware failure. But you should make your own thread with way more information if you want people to take a closer look.

Ah, right. Forgot about AT&T not exactly being so customize friendly, unlike the non-AT&T phones. Scratch what I said in my above post. AT&T phones have more restrictions (security) when it comes to flashing, etc. Use the link above and make sure you find a proper thread that will help you out.

What was the current system you had NB1 Or NC1? I have reflashed my phone plenty of times and if the screen is turning on it's only soft bricked
By the way, you cannot unlock your bootloader! You must use safestrap 3.72 for 4.4.2 for a recovery
I guess it don't matter. Check out this thread

Sounds like you need to flash Odin then start over with the root and rom process. Start here http://forum.xda-developers.com/showthread.php?p=55338138

What was the current system you had NB1 Or NC1? I have reflashed my phone plenty of times and if the screen is turning on it's only soft bricked
By the way, you cannot unlock your bootloader! You must use safestrap 3.72 for 4.4.2 for a recovery
I guess it don't matter. Check out this thread

thank you for pointing me to this post . i was actually able to get out of that black screen by holding the power button n volume button :laugh::good::highfive:
if you are mdl and rooted with a good recovery, you got that message after flashing cwm or any other recovery/rom/kernel that is not loki'd.
research loki-doki. it is an exploit we on mdl need to flash after flashing a non loki'd "file". it bypasses sammy's security check.
most TW roms here in att forum are already loki'd
a lot of like TWRP 2.5.0.2 recovery. i have flashable zip if interested--if you do flash it don't fomat data where you have to select "Yes" and if get a warning root was lost, tap on "Do Not Fix". a couple bugs in it that have been fixed in newer versions, but other than that I have no issues flashing any roms--
:good:

AT&T Galaxy S4 Recovery fails at 24%

My s4 was rooted about a year ago with the logo SAMSUNG and Unlocked with an open lock below it when it boots up. I gave this phone to my girlfriends daughter and forgot to tell her not to try and update it. I don't remember the way i rooted it or what software it had on it at the time.
So when I go to recovery after it loads into an AT&T logo and tries to install it and it gets to 24%. After this it bootloops. Any help would be appreciated. My phone model is SGH-I337 , also not sure of what the original firmware is.

Open lock symbol means your phone is rooted not unlocked.
If you could go to the recovery mode (voloume-up+home+power) it would tell you your firmware version. You could try clear cache, factory reset in recovery mode. If it still gives you the bootloop, you might need to flash the firmware via odin.
You can find instructions and necessary files in here and here.
No recovery options
Sorry I left that part out. When it goes to recovery i get the blue text that say recovery then it goes straight to the AT&T installing. So no recovery options. I can still get to the Odin dowloading screen though and it says im running Samsung Original software

One reason I asked you to go to the recovery option was to know what version of firmware you were on before .
Do you remember you were on jelly bean or kick-kat or lollipop? If you do you can find the firmware for jelly bean and kit-kat on the links I mentioned in the previous message.
If you could not recall your firmware, the latest odin flashable firmware we have is kit-kat NB1.
You can flash that one to revive your phone. Then use twoel root to root the phone. After that you can go to lollipop if you want. All the instructions are there.
Woop Woop!

It worked. I have tried so many different firmware and kit-kat NB1 worked perfectly. Thank you so much, my girlfriends daughter will be so happy. I think i will leave it unrooted for now. I hope this post helps someone else in the future.

I am glad that it works out for you.
Rooting is so easy from that point. Just get towel root and root it. The link also included in my previous post. After the root you might need to disable the AT&T OTA update too. The instructions are also in that post too.
