How to Downgrade your iPhone 2.0 to 1.14 [Updated]
This is a great guide on how to downgrade your iPhone from 2.0 to 1.1.4. Here’s a step by step guide written by _X_ for anyone whose looking to downgrade from 2.0 to 1.14!

Requirements (With Download Links):
iTunes 7.5 (You don’t need iTunes 7.7 for this)
iLiberty+Windows / Mac Version
iPhone1,1_1.1.4_4A102_Restore.ipsw firmware -
KiPhone Windows / Mac (Patched version of ZiPhone) -
(Update: More KiPhone Download Links – Download for Windows – Download for MAC OS X)
Step 1:
Uninstall iTunes 7.7 if you have it and restart your computer
Step 2:
Install iTunes 7.5, iLiberty+ & KiPhone. Make sure only iTunes is running.
Step 3:
Your iPhone should be in 2 states, either stuck on the “Slide to make emergency calls” screen, or you tried to restore before and it’s stuck on the new look “connect to iTunes” screen. Either way, it’s fine.
Enter the phone in DFU mode (You must have the iPhone connected to the computer and iTunes running). To do this, hold the power & the home button down for 9 seconds.
Why 9? Well people say 10, but it depends how slow you are at counting. Too short and it doesn’t work, too long and the apple logo appears.
When you hit about 6/7 the screen should turn off, leave it for 2 more seconds and release the power button, STILL holding the home button. If all went well, you should NOT see an apple logo, the screen should be dead. Keep holding home until windows/Mac informs you that it’s found new hardware, OR iTunes tells you that your iPhone is in recovery mode. Remember, screen should be blank.
If you see an apple logo, repeat the process for less time until you get it right. Took me a little time.
Step 4:
Shift/Option click the restore button in iTunes and select the iPhone1,1_1.1.4 firmware you downloaded.
Fingers crossed it should restore back to 1.1.4.
However, you WILL get an error message when restore is complete, something like (1005) or (1150) I can’t remember. That’s a good sign.
Step 5:
Your phone now should be “stuck” in restore mode, you should see the old type “connect to iTunes” screen.
Close iTunes and run iLiberty+. Click the Other Tools tab and select Jump out of recovery mode.
Keep your eye on the bottom right of the Liberty window; it should change from a flashing recovery mode, to disconnected, within about 5/10 seconds. If it does, that’s a good sign. If it doesn’t, you may need to hard reset the iPhone (holding power and home until screen goes off) and try again.
Once it kicks it out of recovery mode you should see the slide for emergency calls screen on 1.1.4.
After investigation, we realized, you don’t need to kick the phone out of recovery mode to use KiPhone. So you can skip this step altogether.
Step 6:
This is crucial and here’s a little back-story.
When you updated to 2.0, what a lot of people didn’t realize, me included, is that it includes a new baseband file. This is the file which allows your iPhone to make/receive calls, text’s etc. This is what caused me hours and hours of trouble as I couldn’t figure out a way to erase it. The answer was sent to me on another forum and that is,
Now here’s the problem. This guide is what I did up to this point, but what I then went on to do was to jailbreak the iPhone, Google some more and then I found I needed KiPhone.
You shouldn’t need to jailbreak it to run KiPhone but if it fails to work, try it.
Run KiPhone and select downgrade baseband and debug boot. Hit start and your iPhone should restart and you should see lines of scrolling txt. It took a while, 5 minutes or so. (The only way I know of seeing if it worked instantly was by jailbreaking it first, that choice is up to you). Once done you will need to restore the iPhone one more time to 1.1.4 using iTunes. Shift clicking restore should do it, no need to put into recovery mode. (Why do you need to restore again? If you just jailbreak after downgrading the baseband, you can receive calls but not make any, only send texts but not receive any).
The test if it works is when restore is done; it should give you NO errors.
*If for some reason KiPhone crashes out, restore the 1.1.4 firmware again. I found this problem too but a restore fixed the errors. But failing that, and if you cant be bothered, try simply restarting your computer. Solved it for some people.
Step 7:
Using iLiberty+, select the extra repro’s using the advanced menu. This will give you further options like installing installer.app or reallocating ringtones etc.


Dont forget to click download after you have selected the ones you want!
I hope this helps and once again, I would like to give full credit to “_X_” for writing this wonderful guide for us

Hi I accidently updated my iphone 1.1.4 to 2.0. Thanks to _X_ for his genius and Moin. Credit for both of you. After read all the information from _X_ and Moin, I followed all the step until 6. In step 6, I jailed break with Ziphone 3.0 from http://www.ziphone.org before downgrade with KiPhone and then restored again in iTunes. In step 7 I didn’t used iLiberty, instead I used Ziphone 3.0 to jailbreak for me. So far no problem and everthing work perfectly. Thank you very much to _X_ and Moin and thanks to everyone whos shared their experience here.
AWSOOOOOOOOOOOOOOOOOOOOME !
thank u Big time .. that was very helpful .. just follow the steps carfully = D
Thanks man – it worked beautifully!!! I had upgraded to 2.0.2 using winpwn yesterday – BUT HATED IT!!!
and now thanks to you – I’m back on my fav 1.1.4 and loving it as everything just works amazingly.
1. i followed steps 1 – 4
2. i did step 6, didnt work, so i did step 5
3. when failed in step 6, open iliberty and download everything on the list (the jailbreak and everything).
4. since i did the kiphone thing first already and failed (or so i thought), i didnt do it again.
5. iphone running.
I am stuck at step 6 — running KiPhone. I keep getting stuck at “Searching for IPhone”. I’ve tried restoring 1.1.4 firmware and then running KiPhone again several times. Some story.
I also tried kicking out of recovery mode… Firstly, iLiberty for OSX does not have the “Other Tools tab” to select “Jump out of recovery mode”.
Also tried iNdependence…. nothing quite happens, everything is greyed out. And circle keeps turning, Status: Disconnected, waiting for iphone.
Any ideas?
ok i have been trying to download Kiphone since yesterday but it is not working it tells me ERROR each time !! can someone send it to me or tell me where i can download it from other than rapidshare !
Sam, try http://iphone-freak.com/en/page1/page1.html

How long would you say it should take to comlete Step 4?
I am not getting anything. No error of any kind. Just the message “Restoring iPhone software…”
It has been like this for more than 1 hour…
It shouldn’t take longer than 10 minutes to restore your iphone. You should disconnect and try again from the beginning.

hi, I wanna ask you how to download the itunes 5. My itunes is the older one 7.3.1
I’ve seen that in http://www.apple.com there can only download itunes 8. And I’ve try everything to download the itunes 8, but it always seems can’t
i am using itune 8 and was wondering if these instructions will work with itunes 8. so far it hasn’t so was looking for some help/answers. thanks.
i keep on getting error 1606, please help. also after Step 4 and before Step 6, should the iPhone power be turned on or leave it as it is? whn i run KiPhone, the status says “Searching for iPhone…” and doesn’t really do anything. If you have any info, pls help. much appreciated.
i am sorry the error i am getting is 1601 not 1606. my bad.
FYI…as you can tell i have been trying this for days now and one thing i can tell you; every day has been a day closer. but anyways, i will answer my own question about iTunes compatibility, it will not work; you will have to downgrade your iTunes to 7.5…fyi.
YOU NEED TO USE ITUNES 7.5
omg, you guys are the bomb!!! Advice to everyone out there, i can guarantee you if you follow these instructions, IT WILL WORK!!! Believe me!! It took me a little while, but as they said, patience is the virtue. If you can make through the iLiberty stuff, you’ll have your iPhone back. Thank you so much everyone and especially _X_…i got my iPhone back!!!

Hi all,
I’ve been trying for over 5 hours now. getting really tired and sick of this. My 1.1.4 phone was upgraded by my bro to 2.0 and got locked. I have downloaded everything that needs to be downloaded and have reached up to the step of restoring the phone. I keep getting same 1600 errors saying the phone is not in DFU but it is. iliberty+ even confirms it is. I can’t use Iliberty+ or ziphone because they are greyed out and ziphone says I need to restore the phone 1st whcih I can’t do because the phone keeps coming out of DFU in mid restore (it seems). please help me cuz i’m wrecked tired at this stage… thanks in advance
When I get into kiPhone and click Dowgrade Baseband and Debug Boot I click start and nothing happens except the kiPhone window closes. What do I do?
