[ requirements ]

latest FreeXperia Project CM7 ROM (available from here: http://xdaforums.com/showthread.php?t=1128216)

bootloader unlocked

working fastboot

u have read this: [How-To] Safely test custom kernels / custom ROMs and get back to stock SE 2.3 ROM

android app for overclocking like SetCPU (paid) or NoFrills CPU Control (free) OR use CPU Setting under CyanogenMod Settings (Performance)

NoFrills CPU Control (free) to select I/O scheduler

VDD control app: IncrediControl

[OPTIONAL] CIFS Manager (free)

[OPTIONAL] Swapper 2 (free)

[OPTIONAL] xCharge Reboot Otions (paid) [app to reboot into recovery/fastboot mode]

[ how to install ]

download the boot.img

save the boot.img in the folder with fastboot binaries (fastboot.exe files)

power down device

start device in fastboot mode

use the following command to flash the boot.img

fastboot flash boot boot.img

reboot phone and enjoy the kernel ;)

FOR OVERCLOCKING

start SetCPU/NoFrills CPU Control app on ur phone (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)

now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit

DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY

SLOWLY increase the frequency one notch at a time and do stability/testing for few hours
