Downgrading Your iPhone 3.0 To 1.1.4 Firmware

Warning : If you need to downgrade your iPhone 2G running 3.0, this article is for you. Please don’t ask why should you downgrade. MacCiti.com is not responsible, if your phone gets damaged after following this tutorial.

First of, you will need the following software.

1. Apple iTunes 7.5 (Here)
2. ZiPhone 3.0 (Here)
3. KiPhone (Windows, Mac)
4. Firmware 1.1.4 (Google it)

Note : If you have any other version of iTunes installed, please uninstall it. Also delete the iTunes Library located in My Documents -> My Music -> iTunes. In Windows Vista C:\Users\username\Music\iTunes. On the Mac: User/Music/iTunes.

Step 1

Install iTunes 7.5 and reboot your computer. Open taskmanager i.e Ctrl+Alt+Del and go to processes. End task iTunesHelper.exe. On the Mac, go to Utilities/Activity Monitor.

Step 2

Connect the iPhone via USB cable. See whether iTunes detects the iPhone. Either way, open iTunes. Now you have to put your iPhone in 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 in while restoring any firmware.

1. Recovery Mode : This is the mode where you see the cable connector with the itunes logo image on the iPhone. Your iPhone will display the following image on its screen.
2. DFU Mode : This mode is used while flashing your iPhone with a new or a old firmware.

DFU Mode :

1. Turn off your phone.
2. Connect your iPhone to your computer. Start iTunes.
3. Press the home and sleep button together. Keep both of them pressed for 10 seconds.
4. After 10 seconds, release the power button. Please keep your home button pressed.
5. Keep the home button pressed till you see the following screen on your iTunes.

Step 3

Click OK. Now keep your “Shift/Option” Key pressed and click on the restore button in iTunes. Naviagate to iPhone1,1_1.1.4_4A102_Restore.ipsw which you downloaded earlier. 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 (10xx).

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 using the wrong version of iTunes.

Step 4

After you encounter the 10xx error, you will notice the screen of the iPhone is that of the “Recovery Mode”.

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 files into a folder before starting Kiphone.

Run KiPhone with these 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 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 lots of white text scrolling on your iPhone, once the procedure is finished, you will have a UNLOCKED, JAILBROKEN iPhone with firmware 1.1.4.

NOTE: ZiPhone can change IMEI once you are on 1.1.4. You might want to check to make sure it’s legal in your country. Also, you can only use already jailbroken 3.0 (if you decide to change IMEI), otherwise you will revert IMEI back to the original.

Congratulations !
