I found a 2.71 update (8046_EBOOT.PBP) and I saved it to my pc. Then I made an UPDATE folder under the GAME folder on my memory stick. Next I restarted my PSP and went to the Game icon under memory stick and there is no file there? Any suggestions or tips? Anything will help. I want to downgrade to 1.50 to get the new 3.10 firmware. Thanks!
