    Change your thread title to " Downgrade 4.05 firmware".

    You need to get a custom firmware to run homebrew.

    To downgrade (and get a custom firmware) or unbrick your PSP, u need the Pandora's Battery. There is three ways to get the Pandora Battery.

    1. Find a someone who has a Custom Firmware that is willing to let you borrow their psp. You will use their psp to softmod the battery. Meaning using software to make the Pandora. If you willing to do this, follow this guide:
    GUIDE

    2. Hardmod the battery. Meaning that you have to open that battery up, and pulling out a pin. Note that if you pull the wrong one, your battery would be messed. If you are willing to do this, follow this guide
    GUIDE

    3. The most safest way, is to buy the DATEL tool battery. It is already a premade pandora battery. If so, follow this guide or use the same guide on the second step.

    Dude...Don't even help people like this next time. You work way too hard here :). I don't think they deserve it. It's not being mean, it's just stopping the overflow of people asking the same repetitive question...
    Or, if you want to help, direct them to a Pandora guide...

    also make sure the settings in recovery menu (Plain modules in UMD/ISO and Execute BOOT.BIN in UMD/ISO are both disabled.
    Oh, and remember that your Configuration should be 3.71 kernel.
