Start by fully turn off your PSP by holding the power button for a couple of seconds. After the screen goes dark, you know it’s off, and you can let go. Then press the big R button on top, and hold it. Next turn on the PSP (still holding the R button!), and you will see the recovery menu. Simple, eh?
