Back to original software

[fstilts]

Hello,

Sorry I'm new to this psp thing. I have a 1000 phat I think its called.
It won't upload the newest PSP software I keep getting a drnffff error.

Anyone know how to revert this to the original software that came with it.
So I can upgrade an play my games.

Oh sorry I don't know if it helps but I bought this second hand.

thank

I think it's a matter of firmware too.
To verify what firmware is installed juts go to Setting-system setting-information about system (something like that... I don't have the english firmware

hope it helps
