There is no way you can downgrade a PSP-300 or PSPgo at the moment.
You cannot last OFW when you can play isos is 5.03....
how to downgrade psp 4.01 version...i used Pandora and magic memmory but no responce from the psp?
No, Pandora Batteries (the only known way to downgrade PSPs) do not work with the PSP-3000, and, as such, you can not downgrade it.
It is not yet possible to downgrade a PSP 3000 series.
well you cant downgrade your psp but if you go to youtube, there are some fantastic videos on how to do it! just type in "how to downgrade psp's" or "psp downgrade"
It s not possible to "Downgrade" A Psp that has already been patched Improved Answer: You can easily downgrade it without the Pandora battery since you didn't update your PSP passed 5.02. I suggest you don't downgrade since it would be worthless to do so.
Yes, any PSP can be flashed using a Pandora's Battery. To flash the PSP to 1.50 you need to have a Classic (not Slim) PSP and a magic memory stick containing the 1.50 Firmware.

I'm sorry, but you can not downgrade it back to firmware 6.2 Any firmware after around version 5.5 cannot be downgraded i think. It also depends whether you have a psp 2000 or psp 3000 I have a psp 3000 and it was too late for me to downgrade
No but you can get money off the slim
