I dislike the new version a lot. If I reinstall old version will it stay installed or will Live Update ruin it?

LiveUpdate will install the newer V24. The only thing you can do is disable automatic LiveUpdate. But note that that will also not get you the latest local virus definitions and any security related fixes to your 360.
