Hi all, in my haste, I upgraded to 3.73 when I wanted to play some ISO games from my buddy. I am using the FAT PSP. In short, would like to seek any advice if I can do the downgrade if I choose not to use the battery/memory card method? Also, was reading this post, and was hoping to get similar, simple instructions if possible on how to do the downgrade -> http://forums.afterdawn.com/thread_view.cfm/594575. Any advice will be deeply appreciated. Thanks so much.
