Yes, it even has pictures. I asked for help on here and got a bad response (after waiting 2 days for one of course), and looked through your "guides". With no luck, and yes, I did that guide perfectly, I turned to google and came across something amazing.
This Guide. http://www.dcemu.co.uk/vbulletin/showthread.php?t=86997
yes it's an older version, but it gets the job done in less than 20 minutes. All I wanted was my friends PSP to be fixed, and that's what I got. So if anyone is having trouble with these "guides" take a look into that guys thread. It will definitely help you.
Make sure your cfw PSP is 1.5 enabled.
