Hardmod failed- help!

I failed miserably in hardmodding my battery into pandora, but I do posess a magic memory stick. Is there any hope of a penniless bum downgrading for free still, or will I have to buy a tool battery? What I'm basically asking is, is there any way to enable flash0 access through usb on ofw? I'm running 3.50 on a fat, if that helps. Non ta-2086 or whatever the code is, I forget.

If you have a friend with a cfw enabled psp phat yes you can, but otherwise I dont know of any.

that's why I said being really careful

But yeah, now you need a friend with a cfw psp
