[guide]changing themes on any cyanogenmod devices

Once you've installed CyanogenMod on your device, you can change its themes through the base theme settings. The settings let you freely choose from your wallpapers, your navigation bar and even boot animation(BA). Although you can change your wallpaper as barely as in original Android, i believe you can't do the same thing with others. And that's why i'm showing you how to do it, even if you're a noob(actually these are for noobs only).
First ever ever ever, if your device is not CyanogenModded, then quit it! This ain't for you guys! Shoo shoo!
Second, you need to have the theme pack or BA app installed through .apk file that has the theme or BA that you wanted. You can find theme packs either on the Play Store or the internet. But i'm pretty sure you won't find any BA apps on the Play Store. Since it is usually derived in an .apk file, so it's plentiful on the Internet, individually. But there are apps that includes BA packages on the Internet for you to download, but it is a hot mess so i recommend you should stay with the Internet.
After you downloaded them, go to the Themes settings(not in the Settings, ok?).Choose the features you want to change, then choose the one you just downloaded. You just need to recognise the default one with yours. Apply and enjoy theming!
