I seriously do not recommend Android 4.4.4 ROM because it's the worst thing I ever seen first most of apps aren't compatible they say that app could not install or they will crash for no reason also sometimes there's no root access but any other ROM works perfectly fine (if you're reading this and you want Android 4 experience or you just want to run old Android apps just use old version of BlueStacks or nox or any other Android 4 emulator because this isn't for you)
