If you're using windows, here's the simpliest way to install kernels:
Install drivers.
Download and extract these files to some folder.
Place boot.img to the same folder.
Execute flash.cmd.
Turn off your phone, hold volume up button and connect it to pc.
When everything is ready close cmd window and turn on the phone.
If something is wrong try "advanced/wipe dalvik cache" in recovery.
Si necesitas ayuda avisa y de nada ^^
