Sony’s PSP is a fine piece of hardware but, it has only scratched the surface of what the device can do. Hackers have opened up the PSP’s capabilities, allowing it to do far more than Sony ever envisioned.............
Step 1: The Basics
This "hacking" is nothing but removing sony's lame and idioyic firmware and putting "custom" firmware which is much much more powerful
What will I need for hacking my PSP?
You’ll need the following:
A PSP, either original (”fat”) or updated (”Slim”some slims are not fully hackable there are some ways. but most 2000's work but be sure). If you’re unsure which yours is, you have a “fat” if your UMD drive has an “eject” slider that snaps the drive open. You have a “slim” if you have a notch where you pry the UMD door open with your thumbnail (no mechanical door opener).
A spare memory card (512MB is fine)
A Pandora battery
A Magic Memory Stick
Step 2: Pandora battery
A Pandora battery is a PSP battery that has been modified to force a PSP to enter “service mode” when turned on with the modified battery. Putting the PSP into “service mode” allows software to circumvent the PSP’s security measures, and re-write the PSP’s firmware.
1)Take your battery and open it using a knife or exacto knife
2)look on the main board for the display "ICO4" or "CO4" (depending on your battery)
3) Remove pin #5
here is a picture so you get the idea. You can find pin #5 easily when the ICO4 or CO4
__ (pin 4) __ (pin 8)
__ (pin 3) __ (pin 7)
__ (pin 2) __ (pin 6)
__ (pin 1) __ (pin 5)
4) Close it up, wrap it with tape
