How to Downgrade PSP Version Software
The Sony Playstation Portable is portable video game console released in 2005. It plays games through a universal media disk (UMD) drive on the rear of the device, and uses Sony firmware as its operating system. Sony frequently updates its PSP firmware to include and exclude certain features and securities. Once you upgrade your PSP's firmware, there is only one way to downgrade the firmware back to the original, and that is with a Pandora battery.
