    Default Jailbrake my iphone 3g f/w 3.1.3 baseband 05.12.01....?
    Hi

    ive been researching this jailbrake and i no you can jailbrake the version and firmware i have on my fone it is version 3.1.3 model mb 16gb and checked using this version of software like forcast etc and it says its jailbrakable.

    i used snowbreeze to try to jail my my 3g iphone...all going well created my ispw or whatever its called lol and put my fone into recovery mode like the tutorial said, and i open itunes, held down shift key clicked on restore then a box open so i had to select my firmware that blacksnow create from the original firmware i download all going well then a error code 1600 poped up and just stop the jailbrake....what has caused this??

    also would switching the redsnow 0.9.2 work and selecting firmware 3.12 for my 3.1.3? as i saw another post do this many thanks

    i have an iphone 3g
    model mb496b
    firmware 3.1.3 (7e18)
    baseband 5.12

    thanks

    You first have to downgrade it to 3.1.2, then use either redsn0w or blackra1n. A stock firmware will not accept a custom firmware. You can down grade by downloading an official 3.1.2 then use the shift click restore method to install it.

    Yup you can downgrade without any problem. It's the 3gs phones that need the shsh blobs. Your 3g is downgradable to any firmware.

    You can downgrade using the same method you were trying to use to load the custom sn0wbreeze firmware. Instead of selecting the custom firmware when you hold shift+click restore just select a 3.1.2 firmware.

    The error 1600 is caused by trying to load a custom firmware on a nonjailbroken phone. Only jailbroken phones can accept custom firmware.

    You shouldn't even need to put the phone in dfu mode.

    Yup just download an original 3.1.2 and select that in iTunes. You shouldn't even need to put the phone in dfu. Once that's installed you can use either redsn0w or blackra1n to jailbreak.

    Try it in dfu mode. Turn the phone off, Hold home and Power for 10 seconds then release power while continuing to hold home for another 5 seconds.

    They are different operational states of the iPhone. The visible difference is that recovery mode will show a usb cord and an iTunes logo, DFU mode is just a black screen

    Yes that's what it should say if you are in DFU. Is the screen on the phone completely black?

    ModMyi Forums - Downloads - iPhone 3G 3.1.2

    Try doing it with this firmware. It's an official 3.1.2 from this site.

    They SHOULD be the same, but it never hurts to try a different one

    What version of iTunes are you using?
