I recently lost my memory stick with my custom firmware data on it as well as my newer PSP (The screen and buttons broke.) Due to the fact that I used my memory stick with both of my PSP systems, I'm unable to access what I once had. I'm currently unable to update my CFW as well.
I was wondering if there was any way to uninstall my 2000's CFW to reinstall one that I recognize, aside from using a Pandora Battery.
