You can not flash custom ROMS or recoveries on 4.3. You are required to have an unlocked bootloader to be able to do such modding. Verizon and Samsung have perma-locked our bootloaders. No way around it as of now.
If you can get into ODIN mode (vol. down + power + home) you should be able to flash the stock VRUCML1 back to your phone through ODIN 3.07 unless you've hard bricked.
Search the forums for the stock image. But first just try to get into download mode (ODIN). Without that your stuck...good luck.
