159w ago - A few days back we reported on the PS JailBreak Downgrade file leak, and today Hansi of PSXCare.com (linked above) has followed up on some previous work and shared a video of a PS3 downgrading with PS Downgrade and a Beagle 480 USB protocol analyzer.
159w ago - A few days back an FLA file and some instructions were posted to compliment the previously released update software for the PSJailBreak Team's PSDowngrade product, and today the PS JailBreak downgrade files have been leaked through a nice but anonymous source on IRC.
