Running 1.5 / Any other firmware from the MS [Using Pandora] Guide

[Cloudhunter]

Was wondering...

Could the Pandora battery be used to downgrade any PSP? If you purposely bricked a 3.60, or you might not even have to, then ran the pandora battery on it, you could start at 1.5? Is it that easy?

Yes, and you don't even have to brick to do it

Well the downgrader remember actually worked on a SLIM PSP, it crashed when loading the battery but that means it WILL work, after a bit of coding the SLIM PSP could perhaps one day soon be loading 1.50 firmware using this same method...

...Its a great find and the homebrew scene can thrive off this when the SLIM PSP is to be released, I for 1 will work on it

Source this, every report I've seen says it doesn't work.
