if you have a backup of your flash1 then try to restore that via recovery menu, if you dont then last time i checked there's a backup in the flash0 if you look close enough for it, i would be more specific but i dont have my psp offhand right now. just try to recover the firmware then reset the settings. once you make sure everything is working again, then customize it to how you like. if it keeps resetting, then you might want to consider changing what psp firmware you're using and use something like one of the Dark_Alex custom firmwares thjat reformat the psp prior to installing.
