Phone Samsung Galaxy S4 Problem [Need Help Badly]

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:

and/or

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.
Need some help, advice, something fixed? Hit me up on Hangouts @ es0tericcha0s and check out my site: http://mobilemojo5280.com for more info!
