Guys i'm not new in the homebrew buisness, but i kinda got out after i bricked my first psp fm 2.71. Now i've gotten a new one and it has fm 2.80. Is it possible to downgrade it back to 1.5 and then to either 3.30/3.40 OE? If so does the downgrader work for all motherboards? How come i dont see a downgrader on Dark_alex's website? -Peace!
