hey can ne 1 conferm this?
i read this in some forms look-------->
After going through the process, it'll say the firmware installation failed (with error FFFFFFFF) and to call sony. After one restart, a multi-language "fatal error" screen appears (a la "failed XBOX mod", but in blue). It says that you can press O to reload the shipped firmware. Most people do this. Instead, I simply restarted the PSP.
The first restart after the multi-language "corrupt firmware" screen gave me an error, but one more allowed me to boot fully; the system info saying 1.5, but the browser still in the menu and functional, along with homebrew **coughcough*supermariowo rld*coughcough** working as well.
After, I upgraded to 2.0 AGAIN, and downgraded, AGAIN, and instead pressed O to default to the 1.5 firmware at the error screen. Everything works the same, but with no browser. I wanted it, so I upgraded to 2.0, then did the "dirty" downgrade to keep it.
EDIT: The "Dirty" downgrade also allows one to keep the background change utility, but some settings are missing from the system menu that should be there. I'll keep checking for instability. :PC:
