    Default Guide of How I Downgraded from 1.1.2 > 1.1.1

    For Windows

    DO NOT USE THIS TUTORIAL IF YOUR PHONE CAME SHIPPED OR YOU BOUGHT A PHONE WITH THE 1.1.2 FIRMWARE!!

    Download pack without the firmware files inside:http://rapid_share.com/files/7003943...2_Complete.rar (remove the underscore between rapid and share... easy way = right click the link and click copy link location and paste it into a different tap or window and then delete the underscore between rapid and share)

    Okay now you have a 1.1.2 phone that got there from an update not out of the box.

    Start by plugging it into itunes in restore mode (hold home and sleep)

    iTunes will recognize it right away. You will see a restore button. Hold shift and click restore. Navigate to your 1.1.1 firmware file.

    Let it sit through and eventually you will get a 1015 error. Thats perfect. Now you have a 1.1.1 phone with the 1.1.2 modem firmware. We'll handle that later.

    Enter DFU mode. Best solution is to use iBrickr or else its pretty tricky. You have to hold home and sleep and when the screen turns black let go of sleep and keep holding home. iTunes will recognize this and you will shift+click restore and navigate to 1.0.2 firmware files. Let it sit through and you will get a 1013 error and the yellow triange should pop up. Perfect.

    Now click wiNstallerGUI from the package above. Click activate and it should activate the phone as well as jailbreak it. Then hit install application and navigate to the installer.app folder inside the first wiNstaller folder in the downloaded pack. You should now have a 1.0.2 phone still with the 1.1.2 modem firmware but ur activated, jailbroken, and you have installer installed.

    Tap installer and update it. Install Community Sources, than BSD Subsystem, and than OpenSSH. Install WinSCP and click it. Connect to the internet on your iphone and than click the blue arrow next to it and write down the IP. In WinSCP for the host name type in your IP for username type root and for password type dottie. Change file protocal to SCP.

    Navigate to /usr/bin which is in the root of the phone which looks like this: /
    Transfer all the files in the Baseband folder into /usr/bin

    Close WinSCP and open putty. Type in your IP again into hostname and click ok. Type in root and the when it asks for the password type dottie (you wont see the letters when you type, but I assure you, you are typing.)

    Type this into putty and hit enter after each line. Capitals matter.

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

    cd /usr/bin

    chmod +x ieraser

    chmod +x bbupdater

    ieraser

    a crap load of stuff should come up... thats good.. when thats done type

    bbupdater -v

    It should say cant ping to baseband or cant respond to baseband something in that nature i forget exactly. This is good.

    now type:

    bbupdater -f *.fls -e *.eep

    After a 2-3 minute wait it should be done. Now type:

    bbupdater -v (yes again)

    it should show 3.14_08 or whatever the modem firmware for 1.0.2 is

    YAYYY lol

    Now restore to 1.0.2 (just a refresh to get rid of unwanted files)
    Now restore to 1.1.1 and continue on with ur jailbreak unlock process.
    slide emergency tap *#307# and hit call than it should call ur phone erase it and type 0... than hit call > accept > hold > deny... you should be at contacts now. Type a name and for URL type prefs://f and another url jailbreakme.com
    Hit prefs://f and connect to a wifi address.
    Go back home home press 0 > call > accept > hold >deny
    Go back to that contact and now hit jailbreakme.com and scroll down and install appsnapp.

    now ur phone is activated, jailbroken, and has installer.

    Go into installer and install BSD Subsystem. Now go to sources, press edit, then press add. Type i.unlock.no/
    So it should look lke http://i.unlock.no/
    Now there should be unlocking tools in "install" install anysim... set auto lock to never and tap anysim... follow the directions, and your done.

    Voila now you have a 1.1.1 firmware phone with the 1.1.1 modem firmware and its jailbroken, activated, and unlock.

    Please point out any errors I made!

    Thanks,
    Zach

    I verify this is working 100%!!! Great tutorial!! This should be made a sticky instead of the other tutorials that send you all over the internet. The file he attached contains EVERYTHING you need for even noobs to do this perfectly!

    I'm having a very hard time getting the linked file. You instruct that one should remove the underscore but you have two underscores in the link. I tried removing, one, the other, and both and I can not find the file. I also tried deleting the extra periods and every other combination I could think of.

    Thanks!

    One more noob question.

    My iPhone came from the factory with 1.1.1. I Jailbreak'd and AnySIM 1.1'd it a few days ago. I didn't comprehend what the warning "Only works for iTunes activated iPhones!" meant on the 1.1.2 Jailbreak instructions and I decided to upgrade. Everything went fine, and I now have a Jailbreak'd 1.1.2 iPhone (at least I think I do). The problem is it is locked at the slide-for-emergency-calls. I can still use the *#307# trick to access my contacts and the web but if I try to go to the home screen I am kicked back to the slide-for-emergency-calls screen.

    I would like to revert back to either fresh from the factory settings or 1.1.1, or anything that will allow me to use my phone again...as a phone.

    Is this guide designed to work under the conditions described above?

    Thanks, you guys are great.

    Yes if your phone came 1.1.1 out of the box you can follow these directions to get back to 1.1.1.. dont forget to sync with itunes before so you can back up all your stuff

    Yes if you follow what Zach posted at the top, you will restore your 1.1.2 upgraded phone to a working 1.1.1 status. Follow everything in the guide above.

    i think this is little bit easy.

    1. using ibrickr to downgrade your OTB 1.1.2 to 1.0.2
    2. Using winstaller to activate and jailbreak and install Apptap
    3. Install BSD system and vt100 terminal. adding source www.markmon.mine.nu:90/iphone/repo/repo.plist to apptap
    4. then install the 1.1.2 to 1.0.2 baseband script
    5. Type the following commands:
    cd /usr/bin
    restorebb
    5. update to 1.1.1 then using appsnap to unlock your phone with anysim 1.1

    vboyz: I don't think that would work for OTB 1.1.2 because of the new bootloader (4.6 instead of 3.9), so it won't be able to downgrade the baseband or unlock it using anysim 1.2u (or any other version so far).
