You must have a pandora battery in order to downgrade your PSP firmware.
- Reformat your memory stick.
- Take out your PSP Memory Stick and pandora battery, then put back in your PSP Memory Stick first, and put your battery back in.
- Turn your PSP power on, when you see three options; select the Downgrade option, your PSP will be downgraded in a very short time and it will be automatically shut down afterwards.
- Turn your PSP on again, and you will see a blue screen. But no worries, you can just press the O key, and your PSP system is already version 1.5!
