By the way, GREAT tutorial, really easy to follow, and i didn't brick my psp YAY!

You basically just install the original theme, or another custom theme, over the top of your current one.
But sometimes you may not overwrite all the necessary files, so typically you put the original files (remember the backing up step?) back onto flash0, before flashing your custom theme.
I hope you got it :P  Good luck!
