Need Help! Brick? Installed TWRP! Now stuck!

I am currently stuck. My phone only loads up to "Downloading".

I was trying to install TWRP Recovery using this page: TeamWin Projects - TWRP 2.6 - Samsung Galaxy S4 (Verizon) | TeamWin

I couldn't get Goo Manager to actually download the file, so I did it manually and then used the dd command in Terminal emulator. Please help!!!!

1st things 1st. Is your device MDK? ME7? Or what?

It was MJ7

Ah! There's the problem. You will be lucky to even get root. The bootloader is locked down tight and there is no way around it. It will not allow you to install a custom recovery. Your only hope if rooted would be Safestrap if it becomes available for MJ7. You, my friend, are pretty much SOL.

It boots into the screen that has a green android and says "Downloading... Do not turn off target!!"

At the top it says in really small letters,
Could not do normal boot.

Looks like you have to flash a stock rom with either kies or odin.

[ODIN][TAR] VRUEMK2 Emergency and No-Wipe Odin tars - xda-developers

Posted this link in another thread, but I had the same message. Was freaking out until this worked. Didn't even need to wipe my data.

Use odin and flash stock VRUEMK2 I'd do the full aka emergency repair. I used this to uninstall safestrap after trying out hyperdrive rom. I'm now completely stock (rooted) MK2. Just be sure to download the correct stock file. If doing the full wipe, don't forget to download the included Pit file. Be sure to Learn how to use odin. odin is your friend
 
I found the non wipe.tar worked just fine. If it fails, then wipe the device. Just make sure to backup the system using your computer if possible if you haven't made a backup already.
