Use Hellcat Recovery Flasher v1.65 to flash an 5.00 OFW then you can follow this tutorial updating to 6.60 and finally installing the CFW. Flashing OFW can be risky so keep that in mind, do so at your own risk. PSP Recovery Pack Download - this includes the 5.00 update and a 5.00 CFW. I believe from 5.00 CFW you will have no problems updating, although it has been a long time since i did anything with the PSP, so can't be 100%. Just trying to help you the best I can.
