To downgrade (and get a custom firmware) or unbrick your PSP, u need the Pandora's Battery. There is three ways to get the Pandora Battery.
1. Find a someone who has a Custom Firmware that is willing to let you borrow their psp. You will use their psp to softmod the battery. Meaning using software to make the Pandora. If you willing to do this, follow this guide:

2. Hardmod the battery. Meaning that you have to open that battery up, and pulling out a pin. Note that if you pull the wrong one, your battery would be messed. If you are willing to do this, follow this guide
