Homebrew users banned from upgrading
via PSP Fanboy
Many PSP Homebrewers seem upset that they can't upgrade to Sony's latest official firmware. Why? Because they've been using custom firmware on TA-082 PSPs. The 3.30 firmware installer doesn't seem to run on these modified systems, giving a mysterious 'DRNffffffd7 error code." These glitches seem to mirror the many found when Ratchet & Clank was released. So much for respecting the homebrew scene, huh?
Firmware 3.30 gives users some important functionality, such as official support for full-resolution videos and free internet access at T-Mobile Hotspots nationwide. For now, it seems as though users of custom firmware will have to wait until Dark_Alex and the rest of the homebrew community work their magic again.
