There is no way you can downgrade a PSP-300 or PSPgo at the moment.
You cannot downgrade 6.31 on psp 3000
The PSP-3000 cannot be hacked if it has OFW 6.31. There is a way to flash a PSP-3000, using a homebrew enabler, but it only works on OFW 5.03.
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, PSP 3000's cannot be downgraded.
You can't do it.
what you need to do is downgrade then upgrade to the official firmware -- Erm, why would you WANT ofw? The POINT of CFW is that your PSP is free of Sony. I say, upgrade ur CFW to 5.00 m33.. -RLcTstealth
You cannot last OFW when you can play isos is 5.03....
no and i want to ask a question HAVE YOU GOT NFS PS ON YOUR PSP I DO AND IM HALF WAY THREW
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
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
No so far Dark Alex the main creator of psp cfw did not make it for any psp ofw to be downgraded if its past about 4.** ofw. hope this helpes :^) if you go onto google you can find something called chickHEN R2 it will turn the firmware into custom firmware. hope that helps
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.
