    Download Recovery folder (Double click on pic)

    Download mirror
    Download mirror

    Instructions
    *Place folder in (PSP/GAME/RECOVERY) for Going back to 1.50 from any SE or OE firmware PSP
    ok now
    *turn PSP off (hold power switch for at least 10 sec)
    *Turn PSP back on while holding "R" (you will get a Purple or Baby Blue Screen for 3.03oe-c screen this is the recovery main menu)
    *Toggle the USB connectivity.(enable it) now transfer the recovery Folder to (if you haven't already) PSP/GAME/ after copying that Disable the USB
    *Select the 3rd option " Run Program at PSP/GAME/RECOVERY/EBOOT.PBP" 6. Read the agreement, and follow the instructions
    Best of luck to you. and you will have 1.50 soon

    Shutdown your PSP hold onto power button for 5 seconds. When turn on imediately hold down the Right trigger, a blue screen will pop up, look for the recover option, be sure to have the boot file in correct location.
