i have a 3.1oea psp and i want to downgrage it to a 1.5 due to the fact that they seem to be worth more on ebay and i am partin mine out and sellin it to buy a used one. how do i do that? i need step by step instructions due to the fact that my psp's backlight doesnot work and i can not see anything thanks

so i should be able to just get the 1.5 update and run it and it should work?

personally i wouldnt downgrade - 1.5s may seem to be worth more but how often do you see an oe firmware on ebay?... (they sell quickly)
