Pandora's Battery ??

Hi all I have a bricked PSP that was bricked during a 1.5 downgrade and was wondering if anyone knows if the Dark_Alex 2.71 generic downgrader affects the IDstorage about 75% of the way through the downgrade my PSP got knocked down the AC cord came out and so did the battery Is there any hope for my PSP ??
Thanks :(

I heard that if yew have a corrupted IDstorage, you can use the downgrade option while using Pandoras Battery and it will unbrick just fine. Hope that helps
