Default [Q] how to eliminate logo LG GREY on LGP920?

I need file u-boot.bin for lg optimus 3d p920EMU version with no logo LG grey.

I have a" LG P920EMU." I know to use perfectly omap4boot 1. 25. I have resurrected it many times. now I would have the need to change the file U- BOOT. BIN which is located inside" OMAP4BOOT" because they do not want to have more the logo screen LG gray. my question is: where I can find a file U- BOOT. BIN for the P920EMU that does not have the logo LG GREY?
