I was trying too mod the description on a .SFO file on my psp. I took the file and put it on my computer and downloaded PBP unpacker and opened up the file, i took the savedata_detail key and attempted too mod some numbers in it, i then saved the file and put it back on my psp too find corrupted data....... Help plz?

I too have had simular problems. Are you sure you haven't misspelled the file. Try this, save all your files to your computer. After all of your files are transfered,format your memory stick. When it's finished formatting return the saved files from your computer and try to use the file again. Or else just redownload the file and try again. If that doesn't work get a pandora battery and download a custom firmware. Apply it then check the file it should work then. If not then I don't know what will.

if you have 2.82 you don't need a pandora battery...or pandora memorystick. Just download a downgrader and downgrade it to 1.5. If you want custom firmware, follow a tutorial on how to bring it from 1.5 to m-33
