[Guide] iPhone 2.x to 1.1.4 downgrade

[»X«]

If like me, you thought that you could download version 2.0 of the firmware on a jailbroken iPhone (1.1.4) and get all the features, then you were in for a huge fall from grace. I found this out the hard way after spending no less than 18 hours SOLID on the internet, googling, posting on forums etc to get answers.

Now I thought I would make a guide to help people who might be in the same boat.

Don't forget, this shouldn't apply if your on the supported carriers, i.e. AT&T or O2. The iPhone should still work with them, but if not, then this guide will help.

This guide is for you if:

You can't seem to downgrade from 2.0 to 1.1.4, you did but you can't make or receive calls, if that's you skip to Step 6.

Shopping list

You will need the following:

iTunes 7.5 (NOT 7.7)

iLiberty+Windows / Mac < Not essential, feel free to use ZiPhone if it gets the job done.

iPhone1,1_1.1.4_4A102_Restore.ipsw firmware.

KiPhone Windows / Mac (Patched version of ZiPhone)

A Little bit of luck (Sorry, no download link yet ;) )

(Update: More KiPhone Download Links (Thanks MioN)- 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 you're ok.

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.

Make sure also that it truly is in DFU mode and not just off. Check this by using iLiberty. bottom right corner of the window should say DFU mode. If its states disconnected, you have turned it off, obviously.

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, I realised 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,

KiPhone!!

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!

Phew.

Any questions, feel free to ask, I feel I've assimilated too much information on this in the past 24 hours.

FAQ:

I cannot kick out of restore mode what should i do? You don't need to. Not to downgrade the baseband. Don't worry.

I downloaded itune 7.5 when i try to run it a screen pops up saying that iTunes Library.itl cannot be read because it was created by a newer version of iTunes. Simple. Close iTunes. Find the iTunes folder on your hard drive where your library is stored (usually in your music directory). Rename it to iTunes2 or something else. Run iTunes. Once you are done you can delete the newly made iTunes folder and rename your old one back (before you install the latest version).

I keep getting an error 1604 after step 4: Try this article for advice.

I'm having trouble getting KiPhone to find the iPhone: This is because iTunes needs to read the newly restored phone. Try running iTunes first. Also restarting both the iPhone and PC helped others and swap USB if all else fails.

I have followed the guide but I cant make or receive calls!: This is because you havent downgraded the baseband. This step is vital is a working iPhone. Repeat all the steps again.

IMPORTANT

If your still having the 1604 error, try this.

Restore to 1.1.4 and jailbreak the iPhone. Forget the baseband side of things. Use your iPhone+Installer.app to download openSSH.

SSH into your iphone. If you dont know how to, google it. Plenty of internet guides.

Once your into your iPhone,delete the /System/Library/PrivateFrameworks/MobileDevice.framework folder itself. Restore your phone once again to 1.1.4 and retry the guide.

Since 2.0.1 is now out and its already jailbroken etc for us 2G owners, this guide isnt needed really. 2.0.1 is miles better than 2.0 and in turn 1.1.4. The only thing you will miss is a proper installer.app. But hopefully a new version will come out soon!

Good luck!

[»X«]

Very welcome. I know how annoying it is. I joke not when I say I tried for 12 hours solid to fix this. But all is done!

[Andrew Lyle Global Moderator]

thanks! This may come in handy if I accidentally mess something up during the upgrade

[antpooh]

This worked for me to a point. I got the iphone back 1.1.4 but for some reason I can't put music and ringtones on my iphone. When I go to drag and drop onto my iphone I get a circle with line through icon and wont let me add the files to my iphone. Any help?

[funkadelic]

I did all the steps...and the screen turn to white and i was installing the update when suddenly came a 1601 error or something like that.... and i was unable to continue with the process... and ideas...

----

I need hellppp please..

[Bachus]

I went step by step, until Step 5, when I ran iLiberti+.

When I press "Jump out of recovery mode" it never change from a flashing recovery mode, to disconnected.

I also tried with hard reset, the same thing...

Any idea?

I slept for 2 hours, I need to sleep ;(

Thank you

Great post +_X

Like many other Gen 1 iPhone users, when I try to Restore to 1.1.4 I get the Unknown Error (20) just after the File is extracted and can go no further.

Yes, iPhone was in DFU Mode.

I am using iTunes 7.5

I Press the <Shift> Key and clicking Restore

Open File 1.1.4

File extracts fine but the very next screen gives me the ........unknown Error (20)

It loads file Ver 2.0 just fine ...just that it remains Locked with the Emergency number only.

Any one else that is getting Error (20) able to downgrade to Ver 1.1.4? If so, what process was used.

Any assistance would be greatly appreciated.

If you get 16XX Error you just need a new version of Apple Mobile Device Support.

You can get this package from software update , choosing "install and keep package" when updating iTunes to 7.7 (Pkg will be located in Downloads/iTunes

This worked for me to a point. I got the iphone back 1.1.4 but for some reason I can't put music and ringtones on my iphone. When I go to drag and drop onto my iphone I get a circle with line through icon and wont let me add the files to my iphone. Any help?

Have you tried restoring the phone?

OK so are you currently stuck on 2.0? If so try a restore to 2.0 and then try 1.1.4 - sounds like a problem on the upgrade to 2.0 so try it again and then try going back using the method above. Did you use the early link to upgrade to 2.0 or did you upgrade via iTunes?

Use this to get to 2.0 again properly:

http://appldnld.apple.com.edgesuite.net/co...47_Restore.ipsw

you may have flashed iPhone1,2_2.0_5A347_Restore.ipsw which is meant for the 3G iPhone only

I have tried Restore on it's own and that gets me to the Activation Screen. Ver 2.0. No software available to crack it yet (my words).

Then I uninstalled iTunes 7.7 and installed 7.5 and tried Restoring 1.1.4 and this is when I get the Error (20).

I have been trying Itunes 7.7, 7.6, 7.5, 7.4 and they all give me the Error (20).

I have been trying for over 24 hours. I am new to Apple and iPhones...but learning fast. LOL

I have googled Error (20) for the iPhone and there are a lot of Blogs and sites with members reporting this Error code (20). Gen 1 iPhones only and it is happening to PC as as well as MAC users as well.

I am more comfortable using a V-Bulletin than a Blog site so I registered here with hopes of getting my iPhone back up and running.

Any ohter thoughts?

Initially I updated to V2.0 using the iTunes upgrade.

Thanks........but I am aware that the proper file to use is the iPhone 1,1_2.0 (gen 1). and not the iPhone 1, 2_2.0. I thought that may have been the problem at 1st so I restored it with the 1,1_2.0, then tried 1.1.4

I have Restored this file and attempted the 1.1.4 for no less than 40 times easily. Tried with Sim card out as well.

I just keep getting the Error (20) everytime I try to restore Firmware 1.1.4. I even went to other sites to try other files, hoping that the ones I tried were corrupt. But Alas.......that darn Error (20) keeps popping up.

OK, did you try and restore to that ipsw I just posted? I think historically (from what I can remember) people got that Error code 20 when they tried to upgrade their iPod Touch devices to iPhone software

[gaile]

Thank you so much.I have spent 48 hours trying to get my phone back and you provided the solution.Definately learnt my lesson the hard way not to install software until you get the green light

[tech07]

I checked out the link you sent and the file is the same that I have on my hard drive, which I loaded several times. As mentioned before, this file goes in fine and gets me to the Emergency Telephone number and in iTunes, it asks me to activate it.

It is when I try to restore to 1.1.4 on the iPhone in DFU mode that I get the error Message (20)

Here is the file I have been using: iPhone1,1_2.0_5A347_Restore.ipsw C/P from my harddrive

Thank you so much.I have spent 48 hours trying to get my phone back and you provided the solution.Definately learnt my lesson the hard way not to install software until you get the green light

Amen to that gaile.

I will never ever do that again........it is a shame to see the iphone in it's case........rendered totally useless.......until it can be revived again.

OK, are you sure you are in DFU mode and not just restore mode?

1. Turn on iPhone

2. Connect to PC/Mac

3. Open iTunes

4. Hold down power and home buttons

5. Wait untill red slider appears to shut down iPhone - keep holding the buttons.

6.Wait untill the iPhone shuts down

7. Release power button, keep home button pressed (if the Apple logo appeared you didn't release the power button quick enough - try again!)

8. Wait about 7 seconds - iTunes should say there is an iPhone connected in "restore mode"

Yes.

I am definitely in DFU mode.

When my USB notification comes up it recognizes that it is in restore mode and iTunes gives me the 2 options. Update or restore. When I was not in DFU mode I would not get iTunes to log onto the iPhone.

So to answer your question yes. As I mentioned before, I can restore Firmware 2.0 just fine. When I try to restore to 1.1.4, I get the Error (20) Message.

I sent you a PM

[ruchir]

Just wanted to let you know that my house mate loves me thanks to you! Thank you for the details, they were fairly straightforward and I succesfully unlocked his iPhone for him.

Cheers!

[Biofreak]

So i got to 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.

What do you mean by try again? Do you mean i need to restore 1.1.4 update again, each time it fails to kick it back from recovery mode?

To bad it failed to jump out of recovery mode, hopefully 2nd attempt will work. :(

Some additional help would be great, thanks.

EDIT: 2nd attempt worked.

Going on.

Update: Everything worked, thanks a lot.

If like me, you thought that you could download version 2.0 of the firmware on a jailbroken iPhone (1.1.4) and get all the features, then you were in for a huge fall from grace.

Step 7:

This is the hard part, run iLiberty+, select what options you want, select "Go For it" and wait. Once done you will be back using your trusty 1.1.4 iPhone in no time.

Phew.

Any questions, feel free to ask, I feel I've assimilated too much information on this in the past 24 hours.

i got a 1601 error what shall i do??

[»X«]

In my experience, using iTunes 7.7 causes problems, so make sure your not using that.

ALso, once in DFU mode there should be no reason why you cant downgrade.

If it keeps failing, try re-downloading the firmware file using another browser.

But I cant really suggest much else, since this way was the only way it worked for me.

Have you tried restoring the phone?

I tried this with itunes 7.5 and restored to 1.1.4 and didn't work, i still can't add songs to my iphone. Anyone know what the problem is and how do I fix this?

---

Okay now this is strange, I just clicked on the main iphone page in iphone and clicked sync all ringtones and then clicked sync, and all my ringstones that I made were added to my iphone. So my assumption would be that I can do that with my music as well. But I can't drag and drop to add the music I want to my IPhone. Is there soemthing preventing it that I can turn off that'll let me do it manually?
