MacBook pro 2009 15 inch 5.4 to oclp help please

I understand that oclp will not run until I can update to Yosemite first. But following all the youtube can't get there

Any specific tips would be welcome. I can't even get the machine to reset using cmd-ahift-r. It just boots without offering a menu to reset so that I can load Yosemite install. And then after that useboclp to get it to Monterey It has 4gb and original hard drive and 2.5 mhz intel. If it works may add sad and memory
