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.
not that i know of. go to psp-hacks.com. that's were i get all my psp hacks.
I'm not sure what you mean by "the mod" but I think you may be referring to a "custom firmware". If so, you can safely format your PSP's memory stick without removing the custom firmware. This is because the custom firmware is stored in the internal PSP flash memory, not on your memory stick. If you want to remove the custom firmware, you will need to just install an official firmware onto the psp. The easiest way to do this is to put in a PSP game that comes with a firmware upgrade and choose that option. Then I would recommend having the psp do a Network Update.
Cause you need to make you PSP Go To the lowest firmware (kinda like downgrade) Then you can install you custom firmware
No.
New version comes out is the best version but i should be custom firmware because without custom firmware you can not play free games in PSP.
Yes. You need custom firmware.
You just need to upgrade your firmware, then you can access the PSN to purchase and download games.
Custom firmware is needed to do it, and if custom firmware is installed on the PSP in use, a plugin can be installed.
Custom Firmware is illegal<-----EDIT:Thats not what he was asking, please asnwer the question
You must have a firmware installed other than the Official Sony firmware in order to use psp-pda. If you need help putting a "Custom Firmware" onto your psp you can find an almost limitless selection of tutorials online. Then you just need to place it in the game folder.
