I want to get to 2.71se so that i can start with this downgrading stuff. I have a TA whatever notherboard, but i guess recent news says that it doesnt mater anymore. The tutorial assumes you are running a 2.71 psp, however minei s a 2.6 and I don't want to mess anything up...Can anyone help me? I just want to play my final fanftasy tactics on my psp because its been collecting dust ever since my ps1 broke . Any help, or if you could point me in the right direction it would be great. Basically I want to downgrade to 1.5 and be able to run custom firmwares.
