Boot into recovery mode. (Power down by holding the power button up completely until the green LED goes off, then power back on while holding down the Right trigger.)

Select configuration by scrolling down to it and pressing the x button

Note what is says for "game folder homebrew (currently x.xx kernel)"

It might say 3.03. If it does change it to 1.50 by highlighting it (scroll down to it) and then press x. That toggles it to 1.50 or 3.03.

Default selection is "back" press x.

Scroll up to exit press x or select toggle USB to move all your hb into the "ms0:/psp/game150" folder.

Happy homebrewing!
