You'll need odin along with at factory stock ROM image.
Battery pull, then start up in bootloader mode:
> Hold down volume down and the home button, then press and hold the power button. (You're holding three buttons.)
> When the phone vibrates, release power, then release the volume/home buttons.
> Press volume up.
Now you're in bootloader mode.
Grab the factory ROM and Odin3 3.09 and start up ODIN. Plug in your phone and ODIN should recognize it.
Use the "AP" button to open the ROM you need to flash, wait until the MD5 is verified, then hit Start.
Probably the best ROM to flash is the MJ7 Emergency Recovery
ROM as it'll wipe everything on your phone, including your personal data.
My Android devices:
vzw Samsung Galaxy S4 stock MJ7, now rooted!
Samsung Galaxy Tab 2 10.1, also stock but rooted.
VZ Droid Incredible 2 rooted but otherwise stock.
