9g Downgraded to 6.20

Davee uploaded online Downgrader that enables you to downgrade a 9g to 6.20 OFW. Until now 9g was able to downgrade only to OFW above 6.30. How is that possible?

After examining the 4g and 9g modules Davee found out that they have almost no difference. So he was able to find what exacly has changed and to patch it up in order to make the 9g downgrader that support 6.20.

The downgrader, however, is tested only on few PSPs so it’s still kind of dangerous operation and we are not responsible for possible brick. It was reported that 6.20 PRO B9 with permanent patch works just fine and the only thing that is not OK is that PRO B9 thinks the PSP is 4g. This is update of some1?s  Downgrader v4.1 but if you are not with 9g or not downgrading to 6.20 I’ll recommend to use v4.1 instead.

So how to install :

• Add both “Downgrade v5? and “UPDATE” folders to PSP/GAME
• Run the Downgrader from Game-Memory Stick
• Follow the instructions on the screen.
• After the install a blue screen will appear. Press O to restore your settings.(If a white screen splashes instead of the blue one turn off your PSP completely and turn it on again then as fast as you can hit the following combination of buttons : Select+Start+Square+Triangle )
