It is not yet possible to downgrade a PSP 3000 series.
You can't do it.
PSP 2000 is the second PSP Version also known as the PSP slim. There is a newer version called PSP 3000 which more things were added to.
There is no such thing as a 'PSP 3000' game, no game is version specific like that. Any UMD game will work on the 1000, 2000 or 3000 without consideration of the specific version because they're all basically the same.
They are virtually identical. The 3000's lower buttons are rounder, rather than semi-circular on the 2000. The 3000 has an 'advanced' screen, and a built-in microphone.
The PSP 3000 is a much later version compared to the PSP Slim and Lite (or 2000).The main improvements in the PSP 3000 includes a better screen colour and build in mic.I personally like the PSP 3000 more as I find the colours on the PSP 3000 better compared to the PSP2000.

There are no such things as version specific 'PSP1000 games', there are only PSP games, and the UMDs can be played exactly the same on PSP 1000, 2000, 3000 and E1000, but not the GO which lacks a UMD drive.

There is no difference,it's only the model number.The European version is 3000 where as in Asia it is 3004.
