How to get back to 2.71?

[zompton]

I downgraded my psp to 1.5 using the downgrader. I see no use for the version because the n64 emu doesnt have any "playable" games. Can i simplily use one of my umd's to upgrade back to 2.71?

You can that if any of your UMDs have the 2.71 update, or you can download the 2.71 update package from here. But why would you want to go back to the offical 2.71 firmware anyway? You should install the custom firmware 2.71 SE-B instead becuase you can play virtually all homebrew on that.

Or you can just use devhook on 1.5
