You can't do it.
It s not possible to "Downgrade" A Psp that has already been patched Improved Answer: You can easily downgrade it without the Pandora battery since you didn't update your PSP passed 5.02. I suggest you don't downgrade since it would be worthless to do so.
yes u will have to downgrade
download
NOPE, SORRY. Answer 2: lol yes you can downgrade it easily as long you don't update your PSP passed 5.02 which you haven't yet, I suggest you keep it at this version for now if you custom firmware your PSP.
Downgrade your PSP system to version 1.5 by turning your PSP battery into a Pandora's battery. You need are an original PSP battery (with more than 50% charge) and a Memory Stick Pro Duo with 1GB memory or above Users can downgrade their PSP to version 1.5 because they can upgrade their PSP to any version from 1.5. If you upgrade your PSP to version 3.51, you can play any downloaded games and run any applications.

Right now there isn't. If you want to get custom firmware for psp version 6.20 you need to downgrade to custom firmware using a Pandora battery.
You Can Do It Using Pandora Battery.
