Here's my guide on how to downgrade your 6.3x firmware or higher PsP to 6.20 pro perma.
This guide can also be used to "update" to 6.20 pro perma from a lower firmware. To do so, just ignore the parts about the downgrader.

1. Download and move this [You must be registered and logged in to see this link.] to your GAME folder.

2. Download [You must be registered and logged in to see this link.] or [You must be registered and logged in to see this link.] and put the eboot.pbp into the "UPDATE" folder that you'll need to create: PsP>GAME>UPDATE

3. Download [You must be registered and logged in to see this link.] Then extract the "PROUPDATE" and "620PRO Permanent" folders to your GAME folder.

4. Now, run the downgrader. When its done(takes about 30 sec's), the ofw 6.20 update screen will appear. Run the update as usual.

5. Now run the "PROUPDATE". When a screen popups, press the "x" button to install pro. When thats done you'll be sent back to the xmb.

6. Final step, run the 620pro perma. When a screen appears choose the option to fully install perma cfw. When thats all done, you'll be sent back to the xmb.

Congrats, you now have 6.20 pro b-10 perma.

Now that you are successfully on this cfw, you can delete the 6.20 ofw, proupdate, downgrader and 620prop perma patch.
