    Default Theory - idea - How to find a hole in the boot loader 4.06
    Hello Everyone,

    I just have a theory that we may be able to try..

    I assume that iTunes can upgrade the baseband through the bootloader (old and new one).


    Now, I have two scenarios.

    1)

    We get an iphone with the old boot loader. Downgrade it to 1.0.2 and downgrade its baseband. (Many guides are available.).

    Then we use iTunes to upgrade it to 1.1.2 with its baseband. In the sametime we have to sniff the data transfered over the USB using a USB sniffer (USB Snoopy or USB Snoop) and then analyze how iTunes accessed the baseband to be upgraded (DFU mode).

    After analysis we would have the key to interact with the bootloader and try it on the new iphones.

    2)

    We get an iphone with the new boot loader and enter DFU mode, and try to update again. Maybe, iTunes would try to update the baseband.. Sniffing the data would give us a way of interacting with the bootloader to write to baseband.

    I am not sure about this, but it worth to try it.
