I was trying to mod my friends psp slim and i have no idea what went wrong. I made a pandora's battery and then i made the magic memory stick. I popped in the battery downgraded and everything and then fixed the battery with the led pencil thing. Then when i put it back in and turned it back on. It reseted and then the background waves thing came up as long with the date, time, and battery charge level. Nothing else came up at all. I have no clue what i did. I tried re-doing everything and i even tried just installing 3.71. Please help!!!
