Probabily corrupted flash1 partition. Even a simple Pandora firmware restore will not help you.
The best way to recovery it is reflashing an NAND backup using pandora. If you dont have an NAND backup you should use Nand Tools to repartition your NAND.
If you have a Phat PSP you can restore an NAND image of another person with the Pandora (NOT Despertar Cementerio) but without restoring idstorage keys (restore idstorage keys of another PSP will brick your PSP without any change of restauration) and then install firmware 1.50 again.. but it is an deseperate way to recovery it which i dont recomend.
