How to downgrade my psp

Problem:

i dnt know ho to dow grade my psp how can i do this

Solution:

1. The easiest thing to do is buy a Pandora Battery (~$10). Then you need a Magic Memory stick which you can easily make (type it on YouTube). And you can downgrade any Firmware, and it automatically installs custom firmware, which you can play ISO/CSO games!
2. If you create a pandora battery BE CAREFUL! EVERY TIME YOU BOOT THE SYSTEM ON WITH THE PANDORA BATTERY YOU WILL GET THE SCREEN TO FLASH THE SYSTEM! YOU HAVE TO TURN IT ON WITH THE WALL CAHRGER THEN PUT THE BATTERY IN! BE SURE TO GET A NEW BATTERY BEFORE CREATING THE PANDORA BATTERY!
3. you can buy or create a Pandora battery/ Datel tool battery.
