    @Feenix888

    That guide will not help.

    That is for updating custom firmware to a higher custom firmware.

    @Tito66

    Go HERE and use this guide if you know a friend or family member that has a custom firmware PSP. Ask them to help install custom firmware to the PSP.

    Go HERE if you only have access to your Official firmware PSP.
