um i am downgrading my psp soon ive downgraded my brothers and it was pretty easy just took a long time to get it rite lol but yes the pandora thing works. and im not sure about reusing the memory stick i used someone elses also you should downgrade to 1.50 then youy can realy go anywhere from there like custom firmwares
-hope it helped a lil bit

I'd just use a hard mod on the battery, lifting Pin 4 or 5 I think it was...and as for the FW, I'd go with Custom 3.52 last revision...newer ones have a few issues....You can still use the memory stick like a normal one...at least I can use mine, and make sure you put the Homebrew files in the right folders, Good Luck
