yes. just use pandora's battery and magic memory stick. the only time you would need a UMD to downgrade is when u are using GTA LCS (unpatched) or Lumines (unpatched)
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.
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.
There is no way you can downgrade a PSP-300 or PSPgo at the moment.
You can either buy a Pandora's Battery (100% safe) and a Magic Memory Stick, or buy a downgrading UMD disk on eBay (UMD downgraders can brick your PSP). if you upgrade your psp to 5.03 ofw then download chickHEN R2 for psp 5.03 it will get you cfw which is like a downgrade
how to downgrade psp 4.01 version...i used Pandora and magic memmory but no responce from the psp?

A downgrade website for Psp
No, it won't.
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
Insert disk, play. Um if it doesn't work, maybe it's unclean, maybe the disk or the psp is faulty.
