Overclock Xperia Arc To 1.9Ghz With DoomKernel Custom Kernel

The Sony Ericsson Xperia Arc is a beautiful piece of hardware, that did not get the attention it deserved in terms of development effort. With not many custom ROMs or mods out there for this Android device, releases like custom kernels, rather OC kernels fast make headlines amongst the Arc fans. One of these kernels is the new DooMKernel OC kernel by XDA-Developers forum member DooMLord which pushes the phone’s CPU to a massive 1.9Ghz! The kernel is meant for the stock SE 4.0.A.2.368 firmware.

Like what you see? Here’s how you can get this kernel up and running on your device.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.

Requirements:

• Xperia Arc with an Unlocked bootloader. See our guide on unlocking the Arc’s bootloader.
• ADB installed on your system. See our guide on what is ADB and how to install it.
• DooMKernel.

Instructions:

1. To begin, download the kernel from the link above and copy it to the tools folder in the Android SDK where fastboot.exe is.
2. Put the phone in fastboot mode and connect it to the computer.
3. Now run command prompt or terminal and navigate to the tools folder and enter the following command:

   fastboot flash boot boot.img

4. This should flash the kernel to your phone, so reboot the phone now.

That is it! Your phone should now reboot with the new kernel in place and you should also have root access. To overclock, use SetCPU or NoFrills CPU Control from the Market.
