    hi,
    i was wondering if it was possible to downgrade the psp fat's firmware to 1.5 custom firmware, and then restore it to its original firmware?
    thanks

    1.50 isn't a custom firmware, it is the first Sony fimware. What firmware are you currently on?

    i have a psp slim at the moment and a friend of mine has a psp fat and does not want to change the firmware. so was wondering if i can use the psp fat to change the firmware on my psp slim?

    well, to make things easier, you have to change the firmware on the fat psp to custom firmware, so you can get custom firmware on your slim. unless the fat psp already has custom firmware.

    yeah i know you would have to change the firmware on the psp fat in order to get the customer firmware onto the psp slim.
    im asking if it is possible to change the firmware on the psp fat and then reverse the process after i've put the custom firmware on my psp slim?

    it's possible by going back to 1.50 and then updating to the firmware it's at. but i don't know why you'd go back to official, custom fimware is way more versatile, and plays the games more smoothly, since you have access to the cpu speed.

    let your friend try custom firmware. if he doesn't like it, then you can change it back (but once you're on custom, you can't go back. it's that much better)

    does anyone have any idea about how long it'll be till you no longer need a psp fat to upgrade to custom firmware? like just install the custom firmware straight on the psp slim without the need for a psp fat.
