    Exclamation 1.1.2 downgrade to 1.1.1 (or 1.0.2) with baseband downgrade! UNBRICK IT! EURO!

    It may also work for Euro iphones running 1.1.2, not 100%, but don't see why not!

    It seems that the new baseband will not work on 1.1.1, and since it doesn't seem that 1.1.2 can be jailbreaked or activated, those of you who upgraded to 1.1.2 and now have bricks (or semi-bricks if you downgraded to 1.1.1 and can not use phone functions) will have to restore the baseband. Here are the steps and the rar file includes everything you will need, except for the 1.1.1 and 1.0.2 firmware files, which can be downloaded below:

    1) If on 1.1.2, You will now need to go into restore mode on the phone (Hold both buttons, then let go of the power button when the phone turns off and keep holding the home button for a few more seconds, until iTunes says to restore) and downgrade using SHIFT-Restore to 1.1.1

    2) When in 1.1.1, You will now need to go into restore mode on the phone (Hold both buttons, then let go of the power button when the phone turns off and keep holding the home button for a few more seconds, until iTunes says to restore) and downgrade using SHIFT-Restore to 1.0.2

    3) Jailbreak and activate the phone using WINSTALLER (open WinstallerGUI.exe and click on activate)

    4) Install Installer.app using WINSTALLER by clicking on 'Install Application', then selecting the Installer.app folder

    5) Run Installer on your phone, (update if necessary) and install Community Sources (from Sources), BSD Subsystem (from System) and OpenSSH (from System) in that order.

    6) Using WinSCP, connect to your iPhone (user: root password:dottie) and upload:

    ICE03.14.08_G.eep
    ICE03.14.08_G.fls
    iEraser
    bbupdater
    secpack
    secpack.bin

    to /usr/bin on your iPhone.


    7) Using PuTTY, connect to your iphone (again user: root pass:dottie).

    Type in the following: (pressing the ENTER button after each line)

    launchctl

    unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist

    Now type in:

    cd /usr/bin

    chmod +x ieraser

    chmod +x bbupdater

    ieraser

    bbupdater -v

    At this point bbupdater will return saying that it could not ping the baseband. This is good and means it was successfully deleted.


    8) Overwrite with the new baseband by typing in the following:

    bbupdater -f *.fls -e *.eep

    It will run its course. When finished type in:

    bbupdater -v

    It should tell you that you have modem version 03.14.08_G.


    9) You will now need to go back into restore mode on the phone (Hold both buttons, then let go of the power button when the phone turns off and keep holding the home button for a few more seconds, until iTunes says to restore) and using the SHIFT-Restore method, restore to 1.02.

    10) You can now restore to 1.1.1 and use the *#307# method and jailbreakme.com to unlock.

    11) If you unlocked using AnySIM, you will need to reinstall it (In installer.app, add 'i.unlock.no/' (make sure to include that last slash) to your sources, and then you will have a new category called unlocking tools, in which you can install anysim, but make sure to install BSD subsystem again first!

    1.1.2 can be jailbreaked from a Mac using oktoprep and iPhuc. See directions here:

    I was also able to activate 1.1.2 by simply using a hacked lockdownd from 1.1.1.

    (Unlocking 1.1.2, however, I have not yet had success with, so I appreciate the information above. Something went wrong when I used AnySIM 1.2 and now my phone doesn't see any networks)
