Thread: New iphone 3gs 3.1.3 downgrade idea

    Default New iphone 3gs 3.1.3 downgrade idea
    Hi all,

    Does anyone know where the firmware is kept on the logic board?

    I am going to have a go at re-writing the chip with a previous jailbroken iphone dump editing the devices ID so they stay the same e.g UCID etc.

    Anyone tried this previously?

    Neil.
