Question about Sony PSP-3000 Black Console
As far as we know right now, there is no way to downgrade a PSP 3000.
The older PSP 1000 and PSP 2000 systems could accept a special battery called a Pandora's battery and a special memory card with the PSP firmware. This battery would force the PSP to turn on and boot from the memory card. The special software on the memory card would load new system software of your choice (that exists on the memory card) onto your PSP. This includes older firmware or custom firmware.
As far as I know, there is no pandora's battery for the PSP-3000.
