FrancoKernel is a customizable kernel for Android devices. From the less knowledgeable to the most expert user, it combines a series of powerful features to manage and control your device and largely improve your battery life.
There are two methods of installing Franco Kernel on your device. You can either use the FK Kernel Manager to flash the latest kernel version automatically, or you can download and install the kernel by yourself.
Easy method: FK Kernel Manager
Get the FK Kernel Manager app from the Google Play Store.
Open the app and click "Get FrancoKernel", then choose "Auto Flash" from the dropdown menu.
When the download finishes, the Kernel Manager will start the flashing process in the background. The device will reboot automatically with the new kernel when it is complete.
NOTE: If your device isn't supported by Franco Kernel, you can always use the "Manual Flasher" to flash any kernel without having to go to the recovery (if you are rooted, of course).
