OK so I am sure I am having a massive blonde moment here as I have installed custom roms to my phones and tablets many times but any insight would be greatly appreciated, feel free to call me an idiot when you point out the obvious . Everytime I flash C-Rom from CWM I get stuck on the Galaxy S4 initial boot screen.
GT-I9505 (Australia - Telstra)
Rooted (First was Knox safe rooted then tried manually rooted and SuperSU disabling Knox)
Edit: before anyone asks yes I formatted data, did a CWM wipe data, wipe cache and wipe dalvik cache.
Edit2: CM11 + KT kernel flashes and boots fine but as soon as I flash C-Rom and KT it get stuck on the boot logo
