    Default Cannot downgrade iphone 3.1.2 to 1.1.4

    I have been trying to downgrade my 1st generation iphone from 3.1.2 to 1.1.4 (wireless not working issues). However, when i put the iphone in the dfu mode and connect to itunes 7.2.6 or 8.0 or 8.2 i keep getting the error "the ipod software update server could not be contacted"

    I have tried all the suggestions posted on the internet including modifying hosts file but it seems apple has blocked the old versions of itunes from contacting its server when it discovers an iphone in dfu mode. When i connect the iphone in dfu mode to a new version of itunes it recognizes the phone in dfu mode.

    Any help in bypassing this issue to be able to restore iphone to 1.1.4 would be greatly appreciated.

    My details
    Mac OS 10.6 / Windows 7
    Iphone 2G, Model MA712LL, Firmware 04.05.04_G

    First of, you require the following Softwares:

    - Apple iTunes 7.5 (Here)
    - ZiPhone 3.0 (Here)
    - KiPhone : Download KiPhone to help you restore your iphone’s baseband version. (Windows, Mac)
    - Firmware 1.1.4

    Note : If you have any other version of iTunes installed i.e apart from 7.5, please uninstall it! Also Delete the iTunes Library. It's located in My Documents -> My Music -> iTunes. In Windows Vista C:\Users\username\Music\iTunes. On the Mac: User/Music/iTunes

    Step 1

    Assuming you have installed iTunes 7.5 and rebooted your computer. Open up the taskmanager i.e Ctrl+Alt+Del and goto processes. End Task iTunesHelper.exe. On the Mac, go to Utilities/Activity Monitor.

    Step 2

    Connect the iphone via the USB cable. See whether iTunes detects the iPhone. Either ways, whether it detects the phone or not, open up iTunes. Now you have to put your iPhone into DFU mode.

    Step 2.1 – DFU MODE

    This is very important. Please note that there are 2 modes in which your iPhone can be put on while restoring any firmware.

    Recovery Mode: This is the mode where you see the cable connector with the itunes logo image on the iPhone.

    DFU Mode: This mode is used while flashing your iPhone with a new firmware or a old firmware. It is independent of iTunes as well. Most people have the problem of entering into the DFU mode. The main way to distinguish between Recovery mode and the DFU mode is, from the screen of the iPhone. In DFU mode, the screen is completely blank unlike recovery mode.


    Method to get into DFU mode :

    - Please first switch of your fone.
    - See if your phone is connected to your computer. Start iTunes.
    - Press the home button and the sleep/wake button together. Keep both of them pressed. Start counting till 10.
    - After you finish counting till 10, release from the sleep/wake button. only the sleep/wake button. But please keep your home button still pressed!
    - Keep the home button pressed till you see iTunes displaying this message: iPhone in restore mode.


    Step 3

    Click OK. Now keep your “Shift/Option” Key pressed and click on the Restore button. You`ll see that a browse window popped up. Select the iPhone1,1_1.1.4_4A102_Restore.ipsw which we downloaded. Click on Ok. You`ll see that the firmware file is being extracted and Installed.

    Finally during the verification stage, you will encounter an error. (Probably 10xx error).

    Note: As long is it is not a 16xx error, there is nothing to worry about. If you encounter any of the 16xx errors, then there is a 90% chance that you are not using the correct iTunes version.

    Step 4

    After you encounter the 10xx error, you will notice the screen of iPhone is that of the “Recovery Mode” i.e you`ll see the above Recovery mode image on the screen of your iPhone.
    Provided you see this image on your iPhone, Restore the firmware again.

    Thats right, restore the firmware once again.

    Keep the shift/option key pressed and then select the firmware file and restore AGAIN ! –> Very Important

    Step 5

    If you encounter the same error after the second restore, no problem. Quit iTunes.
    Now you have the 1.1.4 firmware with the wrong baseband. To correct it, Open KiPhone. Please unzip all the files into a folder before starting Kiphone.

    Run KiPhone with options
    - Debug Boot – CHECKED
    - iErase – CHECKED
    - downgrade – UNCHECKED

    Step 6

    Once you have performed the task with kiphone, run Itunes 7.5 again and restore the 1.1.4 firmware once again. Now the firmware with the correct baseband will be written. You may have to put your phone into recovery mode/DFU mode if its not being detected by iTunes. Finally to Unlock the iphone follow Step 7.

    Step 7

    Open up ZiPhone 3.0. Click on “Do it ALL” as shown below.


    You`ll see lot of white text scrolling by, once the procedure is finished, you will have a UNLOCKED, JAILBROKEN iPhone with firmware 1.1.4.
