Unfortunately there is not at the moment the only way to do it with a 1000, or 2000 is to use a spare battery. Though you can check if they have any way to use a jigkick battery with a 3000 yet
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, to access the PSN, you need the latest firmware update.
You can't, even with the battery.
There is no way you can downgrade a PSP-300 or PSPgo at the moment.
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
It is not yet possible to downgrade a PSP 3000 series.
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.
No, you can't. And even with a Pandora Battery, you cannot downgrade the 3000 or the late 2000 model.
No. If you have psp 3000 it will but any other psp it will work.
no
it depends on your psp. for example i am using PSP-2000 which i use firmware 4.01 and for my PSP-3000 i am using firmware 5.03.
