ok, im tryin to downgrade my cousins psp (3.52) and i got 3.40oe-a. like i followed all the steps, but it tells me to "Execute 'msipl' application on the PC with the msipl.bin to write the IPL to memory stick." but when i try and open it nuthin happens, am i supposed to put it on the psp's root or sumthing. cuz it will make the battery into a pandora thing, but when i put it in his psp the screen stays black, i know i aint brick it because when i use my battery or plug it works fine,and i can put the battery back to normal and it works fine then, can someone tell if im doin sumthin wrong, or give me a link to sumthin they used please
