How to Install Kernel on Galaxy S2!

What is a kernel a lot of people ask me who are new to Galaxy S2 and Android smartphones.  Kernel is basically the underlying layer that runs your whole operating system, think of it as “MS-DOS” that runs on Windows.

By installing a custom kernel, you can make your phone do more things like overclocking, custom boot animations, and more.  A lot of times, you can install(flash) a new kernel on your stock ROM or custom ROM although sometimes some kernels may not be compatible with the ROM you are running on.

For those of you who want to try out new kernels on your phone, here’s how to install the kernel using ClockworkMod Recovery.

These instructions assume that your Galaxy S2 has been rooted and you have ClockworkMod Recovery installed already.  If you don’t have these, please follow How to Root Galay S2 or How to Root AT&T Galaxy S2 (if you have AT&T version) first.

*NOTE – Make sure you make a backup of your ROM in ClockworkMod Recovery before installation of any kernel as that will allow you to go back and restore your previous kernel and ROM if something goes wrong.

Step 1. Download the kernel you want to install (it should be a zip file) and copy over to the internal storage or external microSD card of your Galaxy S2.

Step 2. For AT&T Galaxy S2, make sure to unplug your microUSB cable as otherwise you will boot into download mode.   Then hold down Volume down, Volume up, and Power button at the same time until you see ClockworkMod Recovery menus.  It may be in orange or blue color.

Step 3. Once in ClockworkMod Recovery, choose “Install zip from sd card”.

You can use Volume buttons to move up and down and Home button or Power button to choose. (This may depend on what version of CWM you are running.)

Step 4. Next choose “choose zip from sdcard”.

Step 5. Choose the kernel zip file you copied over earlier.

Step 6. Choose “Yes”.

Step 7. If you get a successful install message, you are done installing the new kernel.

Step 8. Hit back button to get to the main menu and select “reboot system now”.

Step 9. Your phone should reboot with the new kernel.  If for some reason your kernel ends you up in a bootloop, just do a restore back in ClockworkMod Recovery.

*NOTE – Make sure you make a backup of your ROM in ClockworkMod Recovery before installation of any kernel as that will allow you to go back and restore your previous kernel and ROM if something goes wrong.
