The fine folks at N00bz
have crafted yet another ingenious work of homebrew. This time, it's a program that can recover lost, "bricked" PSP systems from the void -- an unbricker called "Pandora's Battery
." According to N00bz, "It's the culmination of years of behind-the-scenes research and development by some of the top names in PSP hacking, under the name of the Prometheus project."
It appears that the Prometheus project has the top names in the PSP scene: Adrahil, Booster, Cswindle, Dark_AleX, Ditlew, Fanjita, Joek2100, Jim, Mathieulh, Nem, Psp250, Skylark, TyRaNiD. The release of Pandora's battery was supposed to come later, around the time of PSP-2000's launch. However, it appeared that the program was leaked early, and being sold for profit, something that irked the team greatly. "In order to prevent small fortunes being made by leeches, we are giving this unbricker away for free."
Make sure to follow the instructions included with the package carefully. Once you successfully run this unbricker, you'll have a PSP with firmware 1.50 which is ideal for homebrew.
