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.
Sorry, but no.
There is no way you can downgrade a PSP-300 or PSPgo at the moment.
It is not yet possible to downgrade a PSP 3000 series.
No, PSP 3000's cannot be downgraded.
You can't do it.
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 There is no way to downgrade a PSP 3000 to 5.03(The only firmware available for using Custom Firmware). Probably in the future.
NO NOT IF YOU HAVE A NEWER PSP 2000 OR 3000 AND GO but older psp 2000 and all 1000 can downgrade with Pandora battery then hack it and then download 6.35 cfw and install
No, to access the PSN, you need the latest firmware update.
You can't, even with the battery.
I really don't know. All I know after many searching the only way to do that is Pandora battries. I don't want to do this Pasndora battries thing. Answer 2: If its a PSP 3000, then the only way you be able to downgrade is if you ship it in to the Pandora battery company and let them downgrade it to 5.02 or sell your PSP 3000 for a PSP 2000 or 1000 and buy a Pandora Battery Pandora battery is used to go into recovery mode every time you power up the PSP. It does not screw up your PSP.
