[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

they should be (post a link ill check).via ODIN, install UCUAMDB, then UCUAMDL, root and install custom recovery, and freeze the update processes (i forget what they are called, im looking for them now) with titanium backup so that it does not auto update to MF3.
if you happen to know the process names or find them, please PM me im making a thread about it.

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

When you finish downloading and flash firmware by oding go ahad and root ifno here : http://forum.xda-developers.com/showthread.php?t=2314494 then install GooManager from play store https://play.google.com/store/apps/details?id=com.s0up.goomanager&hl=en open and from menu choose install script. good luck

All of the information in this thread is readily available in the stickies located in the "General" section. Looking at those threads might save you a lot of time, some potential problems down the road, and help from making mistakes that have already been mentioned. Good luck.

The firmware from (http://www.sammobile.com/firmwares/1/?model=SGH-I337&pcode=0#firmware) was spot on. Used Odin to restore. Already re-rooted and froze a few of the update apps. Thanks all for the help, added [Solved] and altered the title to help guide searches

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:

LETS BEGIN!!!
Download the Firmware from the Post below
After that unzip it and you will see 2 files, just put your attention to the tar.md5 files

Now you need to install Samsung Kies. (Link also Below)
After installing kies go to the Odin3 Folder, Right click on it and hit "Run as Administrator"
Now that your done with the PC's Part. Put your attention on your tablet and shutdown/Power Off
After that press Volume Down and Home for a few seconds until you get into a screen with a Warning, just press Volume Up to continue.
And after that connect your phone to your PC via USB and Odin should automatically detect it.
An ID:COM[Number] will show in a box on the upper right and then click on PDA and go to the directory of where you put the unziped firmware folder you downloaded from SamMobile. Select the tar.md5 file.
After that make sure you dont have re-partition checked. Double check if you need to and hit "START"
PLEASE DONT REMOVE YOUR PHONE UNTIL YOU SEE A "PASS" MESSAGE IN THE BOX.
After that it should reboot and you now have Android 4.4.2 Kitkat on your GT-N5100!

I would not flash official 4.4.2 kitkat with odin, over kies or over ota. You will get kitkat bootloader with knox, no write permissions for your apps to sd card, no working rooting method which would not trigger knox and void your warranty.
The rooting method he linked does not work for Exynos 4412 devices. Read the comments to the original geohots post in s5 forum or at least the towelroot thread in this section.

Yeah it doesn't work, use CF-Auto-Root. Works perfectly,but you will see SuperSU Force closing or in some cases, it is not installed to fix this, install/update SuperSU
If and onlyif it doesn't work, try again.

Sorry for the newbie question but how can I efficiently and completely backup my device? Any apps/software I can use? I know that I can just make a copy of all my photos, videos, etc to my laptop but how about my apps and its data? Will they be deleted after flashing this firmware?

I've got a problem here .
My simcard doesn't work .
It keep saying emergency calls only
Sent from my GT-I8262 using XDA Free mobile app

efs problematic after flashing firmware N5100
HI, its my first post on xda and new to this world so i will try to be reasonable here.
i followed the steps mentioned in this thread except one, i.e. i didnt make a backup. Now my n5100 wont move beyond initial samsung logo and the recovery mode says "cannot mount / efs"
i also found a thread which makes some excellent points (see below), but i would still like to know if any of you tried this and had a similar problem. if so, did you find a DIY method

"Old" I337 Galaxy S4 failed to root and now won't boot normally

I have two ATT I337's and wanted to root them both. The first and newest one worked fine but it has a busted screen and is locked. It was my test run and went very well except for the wifi problem that many others had trying to load towelroot from the net. Btw, it would be helpful to all going forward if someone would edit those instructions to download say towelroot first!!! I found a solution that I will post later.
Unfortunately my second and primary phone failed early in the process. After I loaded NC1_Stock, it would only boot to either the Recovery menu or the Odin menu. I have tried loading NC1 again, tried NJ4, tried safe mode (will not load), pulling the batt, factory wipe (ouch) and then tried emergency recovery in Kies. NOTHING is working. I did notice that the sticker in this I337 has NO serial number! So with Kies I used the serial from my broken one, on the second one. Unlike my other one which has a serial number on the sticker. So I am not sure if this is an older model, a refurb or what.
I must admit that I did NOT check the original firmware version when I started this process.
In any case I am looking for ANY options to get my i337 working again. Are there any other firmware versions to try? (link pls) Anyone? A phone that only goes into recovery or Odin mode is not much fun!

Honestly, I'm not sure what you did with the two phones with IMEI and stuff lol.
You have to back to NB1 firmware and work from there. Follow this guide until 3rd section on whichever phone you can Odin.
Make sure to completely close or remove Kies software. It's known to cause problems with Odin.

I have gone back to NB1 multiple times(see orig post) and I get the same result. How do I disable Kies if I can only get to recovery or Odin menus? No matter what I do, I can only get to those two menus.

I don't see any mention of NB1 in your original post. If you use the guide I linked to, you don't need to do anything with NC1. You flash NB1 and go straight to OC3.
Just to be sure, you're using this Odin (3.09), right? Because that's the one you need. By disabling Kies, I mean just close the program or remove it from your computer. Both Kies and Odin are independent so you don't need Kies to use Odin and vice versa.

OC3
Apologies. I did not notice that you were saying NB1 instead of NC1. I was able to recover by loading NB1. Thanks! I am using odin 309.
I did try going to NJ4 after recovery, but I lose wifi. Where do I get OC3???

Found it in the link from your first post. After reading through the process I am not sure I really want to go to OC3. Any issue with staying on NB1? Is there a more stable 4.x.x release that I should go to?

OC3 is newest Android version 5.0 (Lollipop). Some people say it eats more battery, but I don't feel any difference. To me, it feel more smoother, faster, and much more fluid. Even my father, who is not tech savvy at all, told me it was faster than before. It's as stable as any 4.x.x. I'd say the update is worth it.
The guide feels longer than it actually takes. You only need to follow sections 1-3 if you want OC3 update. Actually only Section 2 Section 3 since you already have NB1 working. Section 4 is optional. You'll be done within 10 minute max. :good:

You did mean section 3 right? "Upgrading to ROOTED STOCK OC3 (Lollipop) using "keep root" method". Maybe I will give it a try. The download took a while and I still need to go the whole G+ thing.

Yep, I meant Section 3 Root your NB1 if it's not already.
You can avoid G+ thing and download the Flashfire APK directly from here.

Repair malfunctioning Samsumg S4

I have a AT&T Samsung S4 that I would like to give to my daughter. Unfortunately, the S4 is out of whack. First, I keep receiving the message "The device has detected an application attempting to perform actions that are not permitted. These actions have been blocked. It is recommended that you restart your device." Second, Wi-Fi will not turn on. When I try to activate Wi-Fi from the pull down screen, it blinks green and then goes back to gray. Third, I cannot delete any of Knox apps. There is no option that allows me to delete the Know apps, just the option to force stop. Considering that I don't have cellular service (because the purpose of the S4 is just to use on Wi-Fi and download apps for my daughter), I can't really download apps without Wi-Fi.
Is there any way I can get my S4 to function properly again, such as reinstalling software? I'm not tech savvy, so I apologize. A lot of the threads I've come across only address one of the issues. Your assistance is greatly appreciated.

The wi-fi chip could be defective. I also have an i337 sitting in my desk that has no wifi.
You cannot delete knox apps without root.
Did you try a factory reset?

Yes, I did a factory reset. Is there a way to root the device without WiFi access? Given that I can't access WiFi, I can't access the Play store to download the apps I need to root.

You can root the device. But you need to be in stable condition first, like working everything fine and no system message popping up.
Could you tell me your android version, baseband, bootloader etc.. so that I can tell you the directions you need to take.

Look at this thread to get back to stock: http://forum.xda-developers.com/showthread.php?t=2616221

Android Version = 4.3
Baseband = I337UCUFNC1
Build No. = JSS15J.I337UCUEMK2
Kernel Version = 3.40-1921628
Secure Boot Status = Samsung
I hope this is helpful and thank you for your time and assistance with this matter.

You could try smartswitch or Kies to perform a factory restore. If that doesn't work, this thread may help: http://forum.xda-developers.com/showthread.php?t=2616221

It appears that your are on Jellybean 4.3 OS with Kit-kat NC1 modem.
You have several choices.
Like audit13 said you try smartswitch or Kies to perform a factory restore .
If that is not solved your problem you can flash the firmware via odin.
If you are not familiar with using odin this guide explain about the odin.
In that guide you will find the sections about how to get back to MK2 stock and links for the necessary files.
Once you were back on the MK2 stock see whether your wifi is working. If you want to stay on MK2 and root the phone you can use saferoot to root the phone. Here is the link for root.
You could also upgrade your android OS to NC1 Kitkat too. Then you could use Towel root to root the phone.

Thanks for all your help. Unfortunately, I tried the Odin method and during the process i received the Failed message in Odin. I suppose I'm SOL.

Can you post the screen shot of the odin message?

Did you try flashing the latest stock firmware from sammobile.com located here: http://www.sammobile.com/firmwares/database/SGH-I337/ ?

Here's the screenshot of the failed message.

If you download roms from sammobile.com, only unzip the file once and flash in ap.
Since it is stopping at the aboot.mbn file, either the rom you are flashing has an outdated bootloader or the rom is not for your phone.

How would I flash it? Odin?

Yes, ROMs from sammobile are flashed using Odin. Unzip the file once to yield a tar.md5 file. Then, this file is flashed in ap.

Yes I tried the latest stock firmware today and same problem...received Odin message "failed." Given that I cant seem to get back to stock via Odin, I'll probably trash the phone. Thanks for everyone's patience and help.

Dont' give up yet. You could install safestrap to get close to stock.

okay, so i follow safe strap instructions and bypass the odin steps in that thread? thanks for your help.

and just one last note...i cant even get passed the laoding screen. it is stuck so not sure safe strap will work if i cant download the app and get it the phone

What loading screen is it stuck at?
Maybe take it to a cell repair shop to see how much it would cost to force flash the firmware via jtag cable.
