Backup your SD, Wipe Everything, Mount SD in Recovery, Copy ROM,Kernel,Gapps, and Flash them in this Order. Make sure you also have the right Radio. Check the thread I am linking below.
Use Odin, Flash radio but be careful when doing this. That thread has all the info you will need.
If you do not have the latest radio, Flash it before Flashing the ROM/Kernel.
When you flash kernel, use Default settings in the Aroma installer, don't try to tweak anything. Once you are done, reboot, and it should work just fine.
