I got a new PS Vita 2000 because I wanted to use it for homebrew, so I got started according to the steps listed on vita.hacks.guide. Things were going well until it was time to use Modoru to start the downgrading process, once it goes from Modoru to the Settings thing it tosses an error telling me "the file is corrupt" before the entire system reboots, and the system information in the settings reveals that the console is still on version 3.73. Anyone here know what's going on and/or what to do? By the way. the factory firmware was somewhere around 2.50.
