Access your recovery menu (Turn your PSP off, hold the right shoulder button and turn your psp on keeping the right shoulder button pressed)

Go to Configuration/and change "XMB Usb Device" to (Currently: Flash 0)

Connect the PSP to your pc and Select "Advanced" then "Toggle USB (Flash0) this should make the psp show as a removable device in my computer, open it up and go to vsh/ect and edit the "version.txt" their, you just need to change the 9.90 to any number lower than the fw your trying to upgrade to

do no touch any other files or you could brick your psp
