Assuming you are S-ON, you have a ROM/kernel (boot.img) mismatch... remember that you need to extract and flash the boot.img file manually. Although the best way to flash a ROM is to NOT flash it via custom recovery flashed on the phone, but to place a copy of the latest TWRP/CWM recovery.img in your adb directory and boot into fastboot, then execute "fastboot boot recovery.img" and flash the ROM from there. Doing it in this way eliminates the need to flash the boot image seperately.
I actually figured that out this morning!!! I am now up and running with Jelly Bean on my Rezound!!! Now to learn all the fun things there are to do with it! Thanks for the reply!
