Downgrading your iPhone 2.0+ to 1.1.4 firmware
Updated : v1.1
Some users have reported that after installing firmware 1.1.4, the phone doesnt detect the SIM. In this case, the baseband has to be reverted back to the old one. So you have to download one more software called KiPhone and 2 extra steps have been added to show how its done i.e Step 5 and Step 6.
You might be wondering, why I am writing a tutorial about Downgrading an iPhone’s firmware, well 3 days back I got an iPhone 2G from a friend. It was running v2.0 firmware. Since v2.0 firmware doesn`t support the good’ol Installer (Installer : An application used to download and install a wide variety of applications packages hosted online. Something similar to Itunes App Store except this is free 
. Ofcourse data transmission charges are applicable as per your network), I decided to downgrade the firmware to 1.1.4 since there are lots of applications available for download on 1.1.4.
Anyways I decided to run a check on google to find the perfect method to downgrade the firmware and what results were quite disappointing. There were millions of methods and barely any of them worked. (I tried quite a few) So this tutorial is for people like me who wasted hours trying to downgrade their iPhone firmwares but don`t have a clue on how to go about it.
Warning : Vision Master Designs is not responsible, if in any way your phone gets damaged after following this tutorial/procedure. This procedure worked fine for me and so I am posting a simple workaround for people struggling to find a solution on downgrading their phones.
This Procedure is for the 1st generation iPhones
By the way, thanks to apple, your phone can always be restored via iTunes(in the locked state), if anything goes wrong. This Procedure works for both v2.0.0 and v2.0.1
If any queries, you can always post a comment. So read on !
First of, you require the following Softwares.
- Apple iTunes 7.5 : Click Here for a direct Link from Apple
-
ZiPhone 3.0 : Used to Jailbreak,Unlock,Activate and downgrade baseband if necessary, with just a click of a button.
Click Here to Download the Windows version
Click Here to Download the MAC version -
KiPhone : Download KiPhone to help you restore your iphone’s baseband version.
For Windows – Click Here
For Mac – Click Here - Firmware 1.1.4 : Click Here to download
Note : If you have any other version of iTunes installed i.e apart from 7.5, please uninstall it !! Even though you have the latest version of iTunes (i.e 7.7.1) please uninstall it and install iTunes 7.5. Also Delete the iTunes Library.itl located in My Documents -> My Music -> iTunes.
In Windows Vista C:\Users\username\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.
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. Your iPhone will display the following image on its screen.
- 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 to your fone 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 the following screen on your iTunes.
Step 3
Click OK. Now keep your “Shift” 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. (Most 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 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.
You will notice that, ZiPhone automatically installs Installer
You can use installer to install various applications.
In the next post, I`ll tell you how to access the iPhone via SSH and install applications via SSH.
Also I`ll give a list of most wanted applications on the iPhone. Till then Cya
Congratulations !

Hello Doan,
Did you follow step 5 & 6. In some iphones, step 5 & 6 are necessary to enable network reception on it. (It downgrades the baseband version).
If you have done steps 5 & 6 and stil it has not working, you have not performed em correctrly, Please repeat the entire procedure again.

Hello AD,
Since some users have posted this problem, I did a bit research on it. It seems your baseband was also upgraded along with the new version, therefore it has to be reverted back.
I have revised the tutorial. I have added 2 new steps (step 5 & step 6) and a software called KiPhone needs to be used. Please read through the tutorial again.
BTW AD, you directly perform Step 5 & Step6 and then perform Step 7 once again. Download KiPhone (link is given above).
Lemme know the results

Thanks for putting in the time and creating an
outstanding guide

Hi Michael,
Thanks for the tutorial, it’s been very helpful. I’ve followed the steps closely and downgraded to 1.1.4. My problem now is similar to what other people have encountered in that the iphone doesn’t recongnise the SIM. The signal bar is there but my SIM provider is not present like it use to be.
I have version 7.5 of itunes. I’ve tried Ziphone several times, sometimes just jailbreaking and activating. I’ve tried in and out of DFU mode but still nothing.
When itunes asks to restore the phone – should you choose it as a new phone or select the older backup version?
Thanks for your help, it’s been the best I’ve read on the internet.
Cheers

Hi Michael, Thx. I did as u said and then 7.5 worked
– Also have completed the complete process of Downgrading and now I am back to 1.1.4 – THANKS TO YOU !!!
Although had few queries… Plz. if you can guide…
1. While I was in 1.0, when I use to set any wallpaper, I could see it behind my icons as well.. now that I am in 1.1.4, I am unable to see it behind the icons, its just visible while the phone is in Lock mode…
2. Is their from any where I can get a list of sources, which are recommended to be added?
3. How can I get VIDEO TONES ?
4. I didn’t get Installer, have downloaded from the above link u mentioned, however how do I get it in my iPhone ?
LAST BUT NOT THE LEAST In ur above Blog u said “In the next post, I`ll tell you how to access the iPhone via SSH and install applications via SSH.
Also I`ll give a list of most wanted applications on the iPhone. Till then Cya”
If its done, can you give the link to it?

Please check your itunes version. It is very important that it must be v7.5 and not any other version (v8.0 being latest)
Secondly please check whether you are in DFU mode.
If you still get an error lemme now

Well, I tried this procedure and got nada. I tried the Ziphone thing, but didn’t want to do the jailbreak and unlock and activate thing. I only want to downgrade to 1.1.4 So, I tried restoring back to 2.0.2. And that’s where I stand.
September 29, 2008 at 5:10 pm
Hello jamesph,
Try using ZiPhone once again. Open up ZiPhone with your fone connected in DFU mode and then unlock

September 21, 2008 at 2:39 pm
make sure you are using an original firmware (not one created from pwnagetool or any custom ipsw.
after you try a restore and it gives ou a 16xx error. exit dfu mode from the phone and restart back into it.
try restoring it again and you should have some luck
September 19, 2008 at 5:27 pm
Please check your itunes version. Please remove any trace of previously installed itunes. If you had the latest itunes installed before installing itunes 7.5, please remove the library files situated inside your My Documents folder.
Please read the tutorial again.
Now once again, uninstall any itunes you have, remove the library files, and then install itunes downloaded from the link given in this post

hello fad,
This tutorial is not for iphone 3G, btw yes, you can downgrade using this method. A lot of people have been successful in doing so.
if you are not able to do so, you can always put the same version back using itunes restore.
