Thanks to latest release by homebrew developer Yoshihiro, we can now install custom firmware 5.50 GEN-B2 directly on the PSP without a patch. Yoshihiro has dropped a new version of XGEN Updater And XGEN Pandora DC8 Converter.

This application will let you install the 5.50 GEN-B2 into any PSP Fat and Slim TA-79 > TA-88V2 from any custom firmware or kernel exploit without the need for a patch. For those of you who has the firmware 5.50 installed, simply put your updater on root of you memory stick renamed 5.50PBP. You can also use it to restore any official firmware on the Slim and Fat.

More, you can install any TT’s firmware on PSP Fat when you need to put your eboot.php on roots of your memory stick like the X:/EBOOT.PBP. You can also convert your old DC8 magic memory stick in shiny 5.50 GEN-B2.

To do this, “Just select in the XGEN option Install XGEN pandora and restart your psp don’t forget to put the 5.50 eboot.pbp updater on root of your ms renamed in 550.pbp. to bypass the battery check please connect your AC cord,” according to the developer.

A word of caution though, this application could brick your PSP so be careful when installing it.
