So, I had tryed to install at root and flash a Rom onto my Samsung Galaxy s4 i337 using MF3. I was running Android 4.2.2 and when I had tried to unroot my device, something happened and I wasn't able to FULLY get the root off my device. A couple days ago, I had wanted to upgrade to the Android KitKat 4.4 so when I completed the process. It went into Download mode, and then just crashed. Right now it shows an error message saying
"System software not authorized by AT&T has been found on my phone. Please turn off your phone and go to the nearest AT&T store for help."
Also in the top left hand corner it says Secure fail:Kernel so obviously it means I am missing a Kernel of some sort.
Please help me!
How were you trying to upgrade - via OTA? So you have not successfully flashed 4.3 or 4.4.2 through Odin, correct? But you should be able to find everything you need here:

There's a couple different ways to go depending on if you are trying to save your bootloader to be able to downgrade again easier, if wanted, or not.

I've been trying to get my phone back on stock rom for hours or at least to the point where I can use it. Ive tried several methods in the past day. However, I have not been able to do it without success. This was all for the purpose of updating to 4.3 since I hadn't updated since I rooted my phone. First I unrooted it through Supersu and tried to apply the update but it wouldnt work so then I factory reset it. I applied the update again but it didnt seem to want to update to 4.3 . So then I went to TWRP and cleaned out the files, but I never checked to it to the system. After that It was stuck into a boot loop. It never got past the Galaxy s4 boot image. I still have a back up of everything after I rooted my phone, but after applying the following system recovery
stockroms.net/file/GalaxyS4/SPH-L720/L720VPUAMDC_L720SPTAMDC_SPR.zip
I am no longer able to use TWRP and my phone is still in the same situation. All I know about my phone without acess to the information in the about phone section is that it is a Verison Galaxy S4 and before I did anything it was on an android 4.2.2 rooted stock. On the box it say its a SPHl720BKK. If anyone could help me that would be greatly appreciated before I hard brick my phone with the little experiance i have.

You're posting in a forum for the SCH-I545. That's a Verizon Galaxy S4.
The SPH-L720 is an international phone, You'll need to post on a forum for that particular variant of the GS4 if you expect any help.
I just received a notice from Verizonwireless that there is a new software update available. So I went ahead and downloaded the update and attempted to install it. After a few seconds a new window opened showing the stupid Android robot laying on its back and the word "error" displayed. Thinking something bogus is going on with my phone I did a factory erase and retried the software update - same results.
Any way to determine what the error is and correct it so I can do the SW update? Out of curiosity I tried using ClockworkMod Rom Manager to install a custom ROM but got the same error indication.
My phone is a Verizon Galaxy S4 with Andriod version 4.3. The baseband version is I545VRUEMK2.
Thanks.

Sounds like your phone has been rooted / modified. This would be why. Samsung + VZW conspire to make it a mess to update officially when you have modded the phone. Just install the update via the PC and Odin. It is more reliable anyway than OTAs. If there is not an official 4.4 Odin version yet, then install the MK2 update that way and then factory reset then take the OTA.
But sounds like you really aren't sure what you are doing because you should NOT be attempting to use ClockWorkMod Rom Manager on a Verizon S4 with that update!! With the whole locked bootloader fiasco, this operation is not permitted as you can only use the SafeStrap recovery system to load custom roms. Really have to read up some more before you get your phone into a situation it might not find it's way out of...

Hi es0tericcha0s - Thanks for pointing out that Rom Manager shouldn't be used on a VZW Galaxy S4. I knew that but totally forgot about that fact.

You're welcome. What you need is here:
http://nasirtech.blogspot.com/2014/04/i545vrufnc5-android-442-kitkat-firmware.html
Or a 100 other places, but that one came up first.
I also find it best to factory reset after the update for best results.
I was trying to update my Verizon Note 2 (SCH-i605) from 4.1.1 to KitKat. Unfortunately, my boot loader was locked and now all I get is a 'System software not authorized by Verizon...' screen at boot. I've try several tutorials using Odin to restore stock but nothing works. Has anyone else had trouble doing this? Is my phone permanently bricked?
can you get the phone in download mode?
also what did you do to get where you are now, we need some more details in order to help.
I got it back up and running. I got into the predicament in the first place by not unlocking my bootloader. I was trying to flash back to stock with a rooted version. When I used the unrooted, it worked fine.
i have a SCH I545 (verizon s4) and i am currently running kit kat 4.4.2 version vrufnk4 with kernal version 3.4.0. I was once rooted but i am no longer rooted and as far as i know everything is stock except the recovery which seems to be different than what i remember was on the phone from factory. The phone also boots with a logo saying custom with an unlocked pad lock. The recovery says android system recovery <3e> at the top and in the middle is an android dude with a red triangle on him and under him it says no command . I had cwm recovery on the device when i was rooting it but don't remember if i got rid of it or left it but i don't believe this is cwm recovery or the factory recovery. But here is my issue, i wanted to update to the new lollipop via the OTA update verizon has issued for my phone and the update came in 2 parts the first part upgraded kit kat to vrufnk4 and the 2nd update was suppose to be the actual lollipop update. The first update to vrufnk4 did fine but when i try the 2nd update to lollipop GOC1 i believe is what it is the instal fails every time. I did try a factory reset via the boot recovery but that did not help.
Thanks for any help you can give me I'm so lost as to what to do to fix this and i just want lollipop on my phone for now possibly root the phone later if i get bored until i can get a s6 edge.
Did you ever get an exact answer? I'm in the exact same situation and don't want to brick my phone. Thanks... back to searching.
I figured it out l. When you plug you phone into your computer there is a Verizon update that pops up you will need to update your phone using that and it will work like a charm. But it's like Verizon updater or something I can't remember but it pops up when you plug your phone in or it did for me. Hope that helps!
I am going crazy trying to resolve my issue. I was tasked with getting CM13 onto a new S4 I545VRUFNK1. The only root that worked was Kingo Root despite several website claiming that towelroot or one click would work, they DID NOT. After installing TWRP and the 3.0.1 recovery, when i go into recover a Verizon message appears saying the software is not authorized so it won't work.
There are several version of this phone which is contributing to the problem. At this point I want to get a stock rom of 4.4.2 and flash it with odin and get it back to the way it was before I tried to do this.
samsmobile won't let me download, samsung-firmware.org only lets me get 3/4 of it and I can't resume it. Everyone wants money for this firmware and even that seems to not work and I probably have to cancel a credit card and dispute the charge
Can someone please either tell me how to bypass the verizon warning so I can get CM13 (i found a thread that talked about editing some system files, but looked very risky) or even better, help me with a download of the firmware, should be 1.5 GB in size so I can reflash with Odin
Please help before I or the phone break
Use samsung kies for the firmware. You will not get cm13 on nk1, stop trying or you will hard brick.

you are never going to get CM or ASOP or any rom that requires a custom bootloader/recovery/kernel to run on the S4
its not possible
