If you are also a Galaxy S4/S4 Mini user and wish to taste the early Android Lollipop version via unofficial CyanogenMod 12 beta, check out the installation guide.

The same guide can be used to install CM12 builds on Galaxy S4 as well as S4 Mini. Users of respective models should verify the model number of the devices and install the custom build.

Points to remember

As the tutorial might wipe out all data of the phone, create a backup using custom recoveries such as ClockworkMod or, TWRP.

Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Go to Settings>> About phone. Scroll down to Build number, Tap seven times on the build number. The Developer options under Settings should appear now. You can now enable USB debugging mode.]

The Galaxy S4 Mini should have above 80% of battery charge to avoid unusual shut down due to lack of battery, which could damage the device.

The phone should be rooted and have the latest version of ClockworkMod recovery.

The unofficial CyanogenMod 12 ROMs based on Android 5.0 work with Galaxy S4 I9500 or Galaxy S4 Mini (3G/LTE). Applying these on any incorrect variant might brick the device. Verify the model number of the smartphone by navigating to Settings>> About phone>> Model number and install firmware based on the model number of the device.
