Good news for those still sittin’ on firmware 3.41 or lower: drizzt has released fuckPSN v0.5, which
adds support for older PS3 firmwares. Also you should know this…
Previously, in this guide, we asked you to create a backup of CA24.cer and replace the original with
the one provided. Now this is where that backup comes in handy because you’ll be restoring the
original CA24.cer and now we’re working with CA27.cer, which is included. So create a backup of
the original CA27.cer first … you never know when you’ll need it.
Other tips: if fuckPSN does not start or prints “Address already in use” — then you should close or
stop any services using port 80 or 443 on your PC; try also closing Skype and disabling ICS if you
use it.
