Just days after Grand Theft Auto: Liberty City Stories was again used to compromise Sony's PSP firmware (v3.03), a new downgrader application has been released. Those wishing to return -- perhaps for the first time -- to the storied glory of firmware v1.50 need only this trusty guide, Eboots of firmwares 1.50 & 3.03, and an original (unpatched) copy of GTA:LCS (not worth $400).
Downgraders will likely make a quick upgrade to Dark_AleX's custom firmware for a far less restricted (but piracy-prone) PSP experience. Sony is no doubt working quickly to re-secure its porous handheld.
