sorry dude but the only way to downgrade a psp 5.5 is to use a Pandora battery, they cost about 8 dollars at dealextreme.com
or you can plug your PRO DUO stick into the computer and download the version you want. Before you download the the version you have to save it to folders PSP>GAME>UPDATE. Every folder must be in caps. then you put the memory stick into the psp and start the psp. make Sure your battery is fully charged and you must plug the psp into the wall before you take the next step. If you do not follow the instructions located in the the previous sentence or cancel the version from downloading while its downloading it could damage your files. now you go to the games menu and go to memory stick then you will see PSP update ver.... Then you click on it and it will start
Yes, you can. But you must be very careful while downgrading because it can brick your PSP.
Yes but you must "Hack" Your PSP which is not illegal but doing so incorrectly can permanently destroy 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.

what you need to do is downgrade then upgrade to the official firmware -- Erm, why would you WANT ofw? The POINT of CFW is that your PSP is free of Sony. I say, upgrade ur CFW to 5.00 m33.. -RLcTstealth
You can't do it.
I'm sorry, but you can not downgrade it back to firmware 6.2 Any firmware after around version 5.5 cannot be downgraded i think. It also depends whether you have a psp 2000 or psp 3000 I have a psp 3000 and it was too late for me to downgrade
You need your PSP to be upgraded to the latest firmware, in order to access the PSN and download games.
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.
