Okay, so long story short AT&T has cockblocked me from recovering my phone. I know, it has a locked bootloader. I get that. But let me start from the beginning. I was rooted (4.3), and my phone auto updated to KK, and essentially soft-bricked my phone. Well, I had to flash my 4.3 firmware (or so I thought) back onto my phone through Odin. The firmware turned out to be 4.2.2, and all of it failed to flash except the modem. It still started up fine, but I couldn't connect to wifi. It wasn't even an option to turn it on. Turns out I was still on 4.3, with a baseband of MF3, and a build number ending in MK2. I didn't know how to fix this, so I've kinda flashed it with all sorts of things hoping it would help. I've tried all variations of 4.2.2 seeing if I can get things to be all either MF3 or MK2, so far no luck. Well today I tried to flash it with MK2 firmware, and it went like 95% through, and failed. Restarted, and it says "System software not authorized by AT&T has been found on your phone."
This is because of the bootloader, I get it.
The 4.2.2 modem is the only thing to successfully flash. Any clues why? Any clues onto how to recover my phone at all? You guys are true geniuses, please help.
Also, my device status is still on "custom" with the unlocked icon.
Any help would be tremendous, as I feel like a complete and utter moron. I have both Windows 7 & Linux Mint my use, so suggest anything. Please. I'm begging you.
I had the same problem i soft bricked my phone by installing MF3 and i was already on MK2. Just download MK2 http://forum.xda-developers.com/showthread.php?t=2621279 flash first only AP_I337UCUEMK2_1921628_REV06_user_low_ship_MULTI_CERT.tar.md5 by using PDA on oDin see if that fixes your problem.

I had the same exact problem. Flashing CWM Recovery got me out of that nasty screen. You don't need to use the recovery - the mere act of installing it seems to have done the trick for me.
In the end I couldn't root but I am glad my phone works.

Andy Ibanez, I love you man! I thought i was in deep muck when i came across your solution. Thank you once again!
It sounds like you had a failed i.e. partial write and /or partition corruption.
Flashing a custom recovery is an expedient fix, but you may still have corrupt partitions that can cause you problems later. You should find the appropriate PIT (partition information) file to match your current firmware and flash that to assure a stable system.
Hey there
I had the same problem. The screen showed the ' firmware issue' message.
I used the odin 3.09 to flash the CF Root again and this time it worked properly.
i didn't loose any files and the root works perfectly
---- Samsung Galaxy S5 SM-G900H user
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.

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:

See the thread I started with a similar problem.
http://forum.xda-developers.com/galaxy-s4-att/help/rogers-samsung-s4-4-2-2-i337m-wifi-t3256535
Would I be able to use this fix?
Gentlemen/Ladies,
I was putting custom roms on my phone last night, trying a few different out. Obviously I misread (or didn't read) some instruction somewhere and ended up with this lovely message when turning my phone on:
"System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help."
So, what are my options? Can I use Odin or ADB or something to at least get the phone back to stock or am I completely effed and have to walk into a Verizon store? I'm open to suggestions and will probably try all of them.
Please advise,
phoyce

I did (tried) as you suggested. Obviously I'm doing something wrong.
I downloaded the stock Verizon Galaxy S4 SCH-i545 VRUAMDK md5 from [galaxys4root.com/galaxy-s4-stock-firmware]. I boot the phone into download mode, open up Odin (3.09) and flashed using the file above. Odin still fails on the first block.
Is this because what I downloaded was for Android 4.2.2 and my phone was/is 4.4? Or am I downloading the wrong file or simply going about this the wrong way?
Thanks a lot for the help, as you can see I'm still learning.

flash a kitkat stock rom via odin
Hello All,
First let me say I've used xda for a number of previous rootings (moto G, moto X), but this was my first attempt with an ATT Galaxy S7 (SM-G930A).
I was able to root the phone without a problem following the exceedingly useful guides posted here. I was set to start removing all the bloatware from the phone manually, when I saw a ROM had been made with the bloatware removed. I attempted to install the Deodexed & Debloated Stock ROM, with the guide at droidviews.
I installed the ROM through FlashFire without a problem. When I went to Download Mode to install the G930A_PF2_Stock_Modem_Recovery_Bootloader.tar.md5 via ODIN, the installation hung.
Now I am softbricked. I can boot into Download or Recovery, but that's it.
I have tried flashing the phone with virtually every stock ROM I can find, but all to no avail. If I am running the PrinceComey ODIN I get a dismatch error; if I am running the latest ODIN it hangs on SetupConnection.
I have installed and reinstalled the Samsung Drivers, performed a factorty reset from Recovery, followed every guide I can find online to return my phone to Stock, all to no avail.
If anyone can offer any assistance, I would be truly grateful. I'm simply trying to get back to Stock (I can then refollow the steps to root and remove the bloatware myself).
Thank you in advance for any assistance that can be offered. This seems like a brilliant forum!
There is a thread with a member with the PK1 files. PM him for a link. This is the latest ROM from AT&T. His name is @QRhinehardt
Try using different versions of Odin. I used odin 3.12 and not the modified version. There is also another version that will ignore the checksum. I softbricked my phone a couple of days ago, this is how I fixed it.

Thank you very much for your reply. I do think the issues is the incorrect firmware - I've used other versions of ODIN and it get a FAIL! (Auth) error after the attempt at .system.img.ext4. I did some research on that and saw some suggestions to use the original pit file. Still to no avail. That said, I do now know the latest version of ODIN has no problems writing to my phone (given the appropriate permissions and files) so if I can get the right firmware I may well be on track.
Thank you again for the tip, and a very Merry Christmas!
