So iv been reading about dowgrading my psp from 3.60 and I understand that can only happen
by using a pandora battery right?is that the only way?because i dont have a second psp spare
to create a pandora battery so im out of luck?

Yes you have to use the pandora's battery. There is however a method to make the pandora's battery without the need of a second psp. Check the front page, first article for a news post about it. It involves soldering, so if you can't solder then well, your out of luck. :p
