    Default Downgrade to 1.50 firmware?

    Can it be done if I have M33 3.90 running currently on a fat original PSP? And let me know how to as I haven't really toyed with it lately so I'm pretty much a noob.

    You could do it via Pandora yeah.

    Do you have a Pandora/Tool battery and magic memory stick set up?

    No, mine came with 1.5 firmware on it. Fat PSP I thought did not need that battery tool.
