    Are you sure you're using a vanilla 5.00 firmware file?

    That's also an option, yeah.
    Try using a PBP from a different source - if the checksum doesn't match then it's probably borked.

    Are you using a genuine Memory Stick? Are you running any plugins that might interfere with the application?

    Taken straight from the sticky: http://gbatemp.net/threads/how-to-softmod-hack-your-psp.293978/

    Now, you have to reflash 5.00. I had 5.50 Prome-2 way back when on my 1000 model when I first got it, and the only way off of it was to reflash. By trying to officially update, you may have accidentally caused a partial brick. If you can still power on to boot Hellcat's Recovery Flasher though, do it. If you can't and you did brick, the only recovery is through a magic memory stick and a pandora battery, which, lucky for you, the 1000 model is compatible with. To note though, you do need a legit produo stick to create a magic memory stick, as fake cards and adapters won't be magicgate compatible (or at the least, they are highly unlikely to be).

    I do hope you can just run the recovery flasher. It really is super simple and the easiest way to go. If you have to start playing with a pandora battery and such, it will just cost you money and more time all because you jumped the gun and did what basically all old CFW warned you never to ever do, which is why they faked the firmware number to begin with.

    Edit: To note, if the recovery flasher is failing, odds are you really screwed something up. I'd suggest getting a pandora and a produo stick (a legit one), or just buying another PSP. Whichever is easier for you. All PSP models can be hacked to the exact same CFW at this point, so if you can find another model on the cheap, you may be best off going for it.
