Noob mistake...

I just bought a used PSP and when I got home I updated to 4.0 before reviewing this site for instructions on how to proceed. I checked DA's page and it looks like he only has CFW up to 3.9 M33-2. Is there anyway for me to downgrade to 3.9 and install CFW so I can play ISOs?

WHAT?!?!?!?!?!?!?!?!?!?!? 4.00 IS OUT?!?!?!?!?! SHUTUP UR LIEING!!!!!!!!!


Sorry, I was being a geek

You can just make a pandora and flash a CFW with Desperter Cementario.
What typr of PSP do you have PHat or Slim?

So 4.0 is out? I looked on Sony's site but the update they have for download is 3.95.

You need the Pandora's Battery and Magic Memory Stick.

LOL, I just took a look @ 4.00 and its pretty decent. It lets you play music in games(when 4.0M33 comes out, say good bye to the evil music plugin )

I finally got the plugin working on my firmware! Yea thats leet, I'm glad Sony is getting the cfw ideas and making it official . It will work 100% better.

I have a fat PSP

Thanks for responding guys
