This tutorial is for people that want to downgrade to 6.20/6.35 [Image: ouPJWy] [This downgrader only works on firmwares 6.31 / 6.35 / 6.38 / 6.39 / 6.60] (Note: If you are on 6.61 or higher your out of luck)

To start select your PSP® to download a OFW: (Note: This is OFW 6.20 because a HEN is available for it)

[Image: buttonspsp3000.png] [Image: ouPJWy] [Image: buttonspspgo.png]


When you have have finished downloading, You will find a file named EBOOT.PBP.


1: Using your PC, create a folder named "PSP". Within the "PSP" folder, create a folder named "GAME". Within the "GAME" folder, create a folder named "UPDATE". (Folder names must be in all uppercase letters).

       [Image: memorysticko.png][Image: linez.png][Image: folder1l.png][Image: linez.png][Image: folder1l.png][Image: linez.png][Image: folder1l.png][Image: linez.png][Image: pbph.png]
MEMORY STICK         PSP                 GAME               UPDATE            EBOOT

2: Copy the EBOOT.PBP you downloaded to your UPDATE folder.


Now you have to download a downgrader to downgrade your PSP®'s firmware to 6.20 OFW. (This downgrader works only for 6.31 OFW / 6.35 OFW / 6.38 OFW / 6.39 OFW / 6.60 OFW)

To start [Image: ps_btn_dwnld_off.jpg]


Now extract Downgrader.zip file using 7zip or winRAR. You will then find a folder named PSP open it up and you will see a folder named GAME open that up and you will see a folder named Downgrader

Now copy the Downgrader folder to your PSP GAME folder.

RE: 6.XX Downgrader v4.1
Doesn't Work. My 3k 4G won't downgrade. i put the 620 eboot in the update folder and started the downgrader. It said to push X and it jus takes me back to the XMB. By the way I'm on 660 OFW, i can't get 660 Pro to run so i figured i would go back to 620 cfw.
