Default [Q] Change Kernel Boot Splash Logo

Hi All,

How to change kernel boot splash logo?

Facts:
I have LG Optimus 2x (P990). Current ICS kernel have two LG icons splash logo. I'm building my own CM10.1 kang, so I have kernel & android source codes.

What did I tried:
1) initlogo.rle
My ramdisk do not contain any initlogo.rle file. I created new CM10.1 build including my new initlogo.rle. Nothing changed, LG splash logo still remains there.

2) BOOT_LOGO defconfig
I enabled BOOT_LOGO defconfig and replaced 224.ppm picture. Again, nothing happen.

I wonder where can be current splash screen logo located and how can I override it.

I asked same question in our forum, but looks like nobody knows answer. I'm posting it here in hope that maybe somebody solve similar case for other device or maybe have any idea which can help me.

Please, any idea is welcomed! Thanks
