    Downgrade a PS3?

    Wouldn't it be possible to downgrade a PS3 using PS3 ProxyServer GUI, a modified version ps3-update.txt, and replacing the updated firmware link with the firmware that you want to downgrade?

    I'm currently on 2.41, and if I say that the latest firmware is 3.00, the PS3 will then request that I download the latest firmware, which is actually is version 1.10. Won't that work? This is just a thought.

    Nope. The only way to downgrade is with an infectus and a back up of your old firmware at the moment.

    No, you can not downgrade a PS3 to FW 1.00

    And, what do you mean by "beta" FW, you mean DEBUG FW?

    The PS3 checks what FW version you are running therefore if you are running 2.41 and try to downgrade to 1.00 it won't allow you. Once you modify a PS3 update to make it think its a higher update version when its really lower doesn't work either because as soon as you do it you will break the signature on the update.

    But can you download BETA FW on the net on your comp, then transfer the file or file(s) on a SD card or USB memory Stick (Drive)?
