I want to install a custom ROM on my new Galaxy S5 mini, but cyanogenmod doesn't have one, nor does paranoidandroid or AOPK.
I never had trouble finding ROMs for my previous phones.
Look on XDA Forums. There might be something there that does what you want. (Flashing a custom ROM just to have a custom ROM is like having a balloon hovering over your head with your name on it - "Hey, look at me, I'm running a custom ROM." Not worth voiding a warranty just for that. Want a different look, just install a different launcher. Different wallpaper. a different icon set.)
