Please read carefully through the steps. There are always some risks when updating your firmware or installing custom firmware. You can minimize these risks by:
- Having at least 80% battery life
- Making sure your battery will not fall out
- Keep the charger plugged in
Please follow the instructions on this page from Sony on how to update your PSP via computer. It is about halfway down the page. Please notice the folder names and folder layout presented on that page. It is important to follow it exactly. Save the file as “EBOOT.PBP”.
