Asus DRW-24B5ST crossflash to Pioneer PX-891SA

Hello i would like to crossflash my Asus DRW-24B5ST to Pioneer PX-891SA

I know that i need to use official Plextor installator (from where i can download it) and how to do crossflash using unlocked flasher

Thx in advance for any help

PX is for Plextor - not Pioneer!

You right!
Sorry for mistype, any info anyway?
