Dark-Alex has released a new plugin for PSP CFW users. This plugin fakes the firmware version reported to the PC and PS3 via USB, so that PSN downloader does not reject your CFW PSP.
What’s this?
This is a plugin to fake the version that the psp reports via usb to the PC and PS3. This plugin has been made mainly to avoid the psn downloader complain about firmware version.
Instructions: just copy seplugins to the root, and activate the plugin in recovery. The plugin will fake the version to the one contained in seplugins/usbversion.txt, which by default is set to 4.05,but you can set it to other version.
