[Q] Install custom recovery on my s3 3g? topic

I'm using a s3 3g korean which known as Sk 3G or shw-m440s. I've searched for its custom recovery but nothing found :confused: there's only for s3 international i9300 or other, not shw-m440s. I'm intend to install by gt-i9300's one. So anyone can help me to install?
