iPhone 3G Error 3194 when Restoring with iTunes…

Apple just updated its Firmware version into iOS 4.0.1 that has cosmetic signal bar changes that will make your signal more accurate, they said, and with the first and second bar higher than before so it can be seen clearly.

Sadly enough, for you guys who wanted to erase or restore your iPhone 3G into iOS 4 using iTunes 9.2 will be out of luck, since Apple is no longer signing the version 4.0 anymore. Instead if you insist on restoring your iPhone 3G into iOS 4.0 instead of 4.0.1, you’ll have error 3194 on iTunes saying that your Device is not eligible for this build, bla.. bla..

This is unfortunate, you can not upgrade your iPhone 3G officially, but.

You can still restore it unofficially.
Basically when iTunes showing “Verifying with Apple bla…”, that means iTunes is checking for signature from Apple’s signature server. And guess what, Apple no longer sign your iOS 4.0 firmware which makes your device is not elligible for restore, unless you update with iOS 4.0.1, this is one way for apple to force its customer to upgrade into the latest firmware, so all hacks will be elliminated if one is provided in Apple’s latest firmware version.

Now, we can bypass this signature checking when iTunes contacting Apple by changing the server from Apple’s Signature Server into Cydia’s clone of Apple Server.

It’s easy (for Windows):
1. Fired up your cmd.exe, and make sure you have administrator privileges.
2. Type this is: CD \WINDOWS\SYSTEM32\DRIVERS\ETC
3. Type this: edit hosts
4. Add this to the last line: 74.208.10.249 gs.apple.com
5. [UPDATE]: Save the file (People asked me to add this, it’s a common knowledge tho when you change a file you must save it)
6. Restart your iTunes.
7. Put your iPhone 3G in recovery mode, by turn off the device first and pull the plug from your PC. Then press Home Button and connect your iPhone into your PC, then wait until the Recovery Icon shows up (iTunes icon with cable above it).
8. Now, restore your iPhone with your firmware iOS 4.0 (in windows using Shift + Restore, in mac using Options + Restore)
9. Voila, it will be restored succesfully, it’s fully working on my iPhone 3G.

You should notice the number 4 step is the bypass server, by pointing Apple Authentication domain into Cydia’s Server IP Address, this is trivial in unix, and thankfully, we can do this in Windows.

On Mac, it’s the same, except for the cmd.exe and the cd thing should be into /etc/hosts…

Enjoy your Jailbreak Restore…

[UPDATE]
The use of Cydia server doesn’t need you to download any software, but if you still having error using Cydia server, you can download TinyUmbrella from thefirmwareumbrella.blogspot.com

You can then start its TSS server and replace the step number 4 with :

127.0.0.1 gs.apple.com

And still on the very same hosts file. Some people called it stupid, but this is simple way to bypass the iTunes from connecting to the real Apple Server, if you have better way to do this, just tell me…

      The easy way is for you to create a shortcut on your Desktop by right click on the Desktop, then choose New -> Shortcut, then fill cmd.exe.
      Now after the shortcut created, right click it, and choose, Run As Administrator, this way you can edit system files with no problem. The rest is just like my post.

      Hope this will help, if otherwise, I can help you, just put a comment and I will reply, or if you want fast reply just send it to my email, syuaibi [at] yahoo [dot] com.

    I went to the the directory \WINDOWS\SYSTEM32\DRIVERS\ETC and manually added the line on notepad instead of using cmd. Everything worked great. Will this also work with ios 4.0.1 now that it’s also not signed?

    Hi just a few questions…does it work for IPhone 3GS version 4.0.2?

    Also, after ’4. Add this to the last line: 74.208.10.249 gs.apple.com –> do you need to save or close the box?”

    Help is much much appreciated!

    • azacode
      September 20, 2010 at 1:12 am | #38

      It works for 4.0.2 as long as you have Cydia stores your shsh,just visit cydia to save your shsh

    • azacode
      September 20, 2010 at 1:14 am | #39

  27. nadz
    September 20, 2010 at 1:51 am | #42

    This is incomplete. Do you have to press enter after the CD \WINDOWS\SYSTEM32\DRIVERS\ETC ? Do you press another enter after you type “edit hosts”? Because when I do that I enter into a blue screen and then I type the 74…gs.apple.com line at the end and it does nothing when i press enter – so what is there to do after that?? Do you have to SAVE it? Because it’s not in your procedure. I don’t know what all these guys KNOW that ordinary people like I dont. If I type-type-add like what you say here though without pressing “Enter” or do nothing else but
    TYPE
    TYPE; and
    ADD
    it says “not found…” of course. Please complete the procedure for me including the basics…thanks

    September 20, 2010 at 1:58 am | #43

    I added the code at the bottom but still can’t restore to 4.0.2 or earlier from 4.1. I have a 3G and my SHSH’s are on file with Cydia last time I checked my JB before updating. I saved the host file. Is there anything I could be doing wrong?

    • azacode
      September 21, 2010 at 2:18 am | #45

      Reopen the hosts file on its directory see if everything is there. And try to restart your iTunes,if that still not working try to ping the ip address that you type in hosts file if it ok you’ll have some data transferred to cydia server,if not then you might have problem with your connection,check your network and firewall,then restart your computer and try again. It should be working,if its working on the other why woudnt it work in your computer,then it must be something wrong with your settings.

      Sorry too my friend, please read carefully my post, and check the date of my post, before making comments.

      I did mention that this is for SHSH that stored by Cydia. local SSH files is for when you use TinyUmbrella.
      If you want to use local SHSH file, just use TinyUmbrella. It’s not a stupid idea, since even saurik using it. It’s a simple bypass method. It’s not a high tech method. So feel free for use or not using it by all means.

      And by the way this is only safe keeping for my iPhone 3G.

    • azacode
      October 2, 2010 at 3:49 pm | #59

      You can use notepad, like this:

      Start Menu, then Find for Accesories, right click Notepad, choose Run As Administrator

      then in Notepad, File->Open, in the file name type the path:
      C:\Windows\System32\Drivers\etc

      In the file type next to it, change it from Text Documents, with All Files (*.*), then open file: hosts

      Then follow my steps again number 4, and don’t forget to save.

      Restart your iTunes, if it’s still not working, restart, if it’s still not working, use TinyUmbrella instead.

      I use my steps all the time until now, it always works like a charm.
      Sorry, my background is Unix, so I like cmd.exe better than Notepad.

      But, use notepad for your convinience.

      Hope this help..

    Might be worth stating explicitly for new viewers that this relies on cached SHSH blobs from your own unit.

    • azacode
      October 6, 2010 at 2:34 pm | #61

      It was using Cydia’s server to store your iPhone SHSH blobs. I thought I made it clear on my post. Everytime you open Cydia, you must see that Cydia wrote your SHSH for every iOS version on the top. Just open Cydia, and your life will be easier.

    • azacode
      October 19, 2010 at 8:34 am | #69

      It’s not for jailbreak It’s for restore your iPhone to lower or higher version of stock iOS firmware that Apple no longer signed.

      For jailbreak use greenpois0n, PwnageTool, Limer4in, or you can craft yourself a code to do the jailbreak

  48. October 18, 2010 at 3:12 am | #70

    I’m a first time jailbreaker, got really confused about how to enter in the correct code commands in cdm or even notepad, to bypass apple signature for restoring Iphone 3G to iOS4.0, i’ve read & reread your instructions, still just confused how to execute them properly, thx in advance.

  49. October 19, 2010 at 7:41 am | #71

    Soooo cool! So EZ! Thanks
    Marcus just type in the correct commands then add a new line at the end like the instructions say. It worked for me once I saved it. Is it when you restore that you are having an issue? Make sure you have saved the ipsw file. Here is where I downloaded the file
    http://www.iclarified.com/entry/index.php?enid=750
    click on the file then hit ‘save as’ and change the zip to ‘ipsw’. Then when you are in itunes and click on shift and restore you will just need to find that file -click on it and wallah! you should be good to go. Good luck!

    so i tried to reset my jailbroken iphone (firmware 4.0.1) and when i did it, it reboots and goes to the apple logo and gets stuck there. umm dont know what to do really, i dont want to update it to 4.1 because they say its not jailbreakable. so im stuck here lost. i tried to restore it using a method of plugging it in to the itunes and restoring it with the shift thing but when i go to hosts n try to add 74.208.105.171 gs.apple.com it says “Cannot Create the c:\WINDOWS\system32\drivers\etc\hosts file. Make sure the path and filename are correct.” also it says in itunes that error 3194…any suggestions?

    • azacode
      November 8, 2010 at 9:20 am | #80

      Jailbreak it with 4.1 using PwnageTool, it’s Jailbreakable, use PwnageTool, so you won’t loose your baseband, and remember, use PwnageTool’s or RedSn0w’s (in windows) DFU button to make your iPhone to DFU mode, so it can be restored using custom PwnageTool iOS 4.1 firmware, I did it, mine is iPhone 3G iOS 4.1 using PwnageTool with baseband intact 5.13.04. iOS 4.0.1 for iPhone is so slow compared with 4.1.

      Cool, but, don’t try this with iPhone 4 on iOS 4.2.1, some people reported it was a recovery loop using cydia’s server and tiny umbrella.

      Yes, greedy Apple, and yet we use its products… irony..

    Hello azacode,yesterday i tried to unlock my iphone and as you know, you have to have the ipad firmware and now i have the same error as everyone and i tried everything possible!
    Can you please help me out?
    thank you

      December 1, 2010 at 6:17 am | #95

      What baseband version do you have right now? If you have Basebasend > 5.13.04, downgrading your iPhone won’t make your unlock works, unless you upgrade your baseband into 6 which is iPad baseband that has the same vulnerability like BB <=5.13.04.

      I'm not clear of you want to do? If you can give me more detail, I might be able to help…

    Please help

    changed the hosts file, saved successfully.
    trying to upgrade to 4.0.2, still having the 3194 unknown error. Tried to download tiny umbrella tinyumbrella-4.21.01.exe cant run because of java. installed jave, still not able to set up tinyumbrella.

    Any ideas anyone? please. thanks

    • azacode
      December 6, 2010 at 3:02 am | #97

      Do not upgrade to 4.0.2, that’s my suggestion, upgrade to 4.1, use PwnageTool and hit the DFU button to make your iPhone into exploit DFU mode, this so you can restore using iTunes, do not go into DFU yourself, use PwnageTool DFU or RedSn0w DFU.

      As for TinyUmbrella, right click the file then choose Open With, then Choose Java Web Start (if I’m not mistaken).

    Hi azacode, I have done all the things that you have asked us to do. But when the iPhone reboots it again goes to restore mode. After that i have tried to restore it with redsn0w 0.95 but after whole of the process it goes again into recovery mode…please help!

    • azacode
      December 6, 2010 at 3:00 am | #99

      What firmware you are updating to? if you have recovery loop, then use TinyUmbrella to kick out of recovery loop

    Ok im back again. Last time it worked downgrading from 4.1 to 4.0 but now when i want to go from 4.0 to 3.1.3 it doesn’t seem to be working. It had already saved the diversion ip obviously so i tried downgrading straight away but no luck. Tried repeating the whole thing, still no luck and same error. I must be missing something new, it worked before. Thanks in advance

    • azacode

      3.1.3 doesn’t need an SHSH…

      • Simon
        December 6, 2010 at 4:41 pm | #102

        What exactly are you suggesting? I’m gonna try without the cydia bypass server, but I’ve read online that it won’t work that way either.

      • azacode
        December 8, 2010 at 5:07 am | #103

        I downgraded to 3.1.3 so many times, I never need a SHSH for 3.1.3 because it doesn’t use soft blobs, 3.1.3 is already signed by Apple, no need for Signature Window from Apple. Just try to remove all of the changes you made into hosts, and don’t use Cydia or TinyUmbrella. If you already have a custom 3.1.3 using PwnageTool, then it’ll work by making your iPhone into DFU mode. I used custom 3.1.3 firmware baked using PwnageTool, and when restoring your iPhone into 3.1.3 using normal mode or restore mode not working, use DFU mode.

        DFU: Press Sleep + Home for 10 seconds, then after 10 seconds release the sleep button but keep pressing the home button for another 10 seconds, make sure your iPhone connected to your PC, so when your iPhone enter DFU mode, it will automatically detected by iTunes, after you have it on DFU mode, just restore using your 3.1.3 pwnagetool custom firmware.

        This works on me, many times…..

        Hope this help…

    is this what im suppose to do if i tried to unlock it, i followed all the steps and after it rebooted the Cydia icon wasnt working so i decided to restore to see if it help but inside it doesn’t let me use the phone and now its stuck on the “connect to itunes” screen. Then i tried doing what you said but it wont let me save it, it says: cannot create file…please help me…:(

    • azacode
      December 15, 2010 at 8:43 am | #109

      This post is not for unlock, this is for downgrade/upgrade to iOS firmware that Apple no longer signed, like 4.0, 4.01, 4.0.2.
      Your device is not activated, so the connect to iTunes appear. You can use the original sim card and activate with iTunes, if you don’t have any, then use Redsn0w (on Windows or Mac) to jailbreak and activate it. There are plenty tutorials out there that can help you to use Redsn0w, Google is your friend. Then if you want to unlock find tutorial of Ultrasn0w to unlock it, again Google is your friend

      If you can’t use edit, then use notepad. Just open notepad, then run it as administrator, browse to the hosts file, edit it, and save it.

    • azacode
      December 27, 2010 at 9:48 am | #113

      If you can’t use edit, then use notepad, just open notepad, by right clicking it and choose Run As Administrator, thenb browse for the hosts file, edit it, then save it.

      Sorry, I was an old school person, mostly used terminal or cmd to get my jobs done, you can do the similar things using notepad or ultraedit.

    ok so there are some queries i hope u’re able to clarify for me:

    1- I have an Ipod 4G which was running IOS 4.1. Your way will work on it right?

    2- I am downloading the firmware from this site: http://www.felixbruns.de/iPod/firmware/ and I am downloading IOS 4.1. Is that the right way to go?

    3- after I did the ip host thing, I tried to restore the ipod by pressing the same “restore” button on itunes, and the same error showed up. is that normal becoz i used the IOS restore that was downloaded by itunes itself?

    thank you soo much for helping us out :)

    • azacode
      December 28, 2010 at 1:03 am | #117

      1. Under right circumstances, it will work with Cydia’s Signing Server
      2. If you already have iOS 4.1 why would you upgrade to the same iOS 4.1? You can download it from trusted site, I like to download from this website: http://www.iphoneheat.com/2010/10/download-custom-ios-4-1-firmware-ipsw/
      3. Make sure your iPod is in DFU mode if by some way it has error when restoring in normal mode or restore mode. How to make your iPod in DFU mode, read my previous replies. Do not use that restore button, use Shift Restore that will browse the ipsw, and choose your downloaded ipsw. I reccomend this way, rather than downloaded by iTunes.

      • traveller
        December 28, 2010 at 8:23 am | #118

        Azacode,

        I have followed steps 1 to 9 and the same error 3194 is still showing, even with the shift restore.

        I’ll give you an overview on my situation, maybe you can find the problem:

        - got the ipod, jailbroke it with limera1n.
        - installed Cydia and then tried to get some sources to add which showed me “Size missmatch”error on the Ipod.
        - I thought it would be a good idea to restore the device and then try again
        - I restored it from the device itself, not through itunes.
        - It always froze when the Logo of Apple appears with a frozen busy sign and nothing happens
        - so I tried to use your steps 1-9 going into DFU MODE, which is the only mode that is replying now in my phone, and i keep getting the error.
        - IOS 4.1 was runing on the ipod.

        should I be doing something differently? should i give it to Apple to restore it for me? or should i call it dead?:(

        thanks :)

    My problem is a little different than the ones listed here. I have an iphone 3gs that i’m trying to jailbreak. Read that if you download the 4.2.1 fw and you jailbreak to ipad baseband using redsnow you can also unlock. i’ve tried a bunch of different ways and my iphone always turns back on during the process and says iphone is disabled. i’m not sure what to do

    Hello Azacode, have tried your steps a number of times, but still cannot get past the error 3194. When OS4 was launched, then i had upgraded my 3G to OS4.0, however, because of slowness, downgraded it back to 3.1.3. Current modem firmware is 5.13.04. Now i want to go back to 4.0.1 / 4.1, but the error keeps popping up. Have tried in recovery as well as DFU mode. have tried timyumbrella (v 4.21.02) as well. My SSH are saved on Cydia as tinyumbrella gives me a huge list of SSH saved (4.0 to 4.2b3)

    what is it that i am doing wrong? thanx in advance

    • azacode
      January 6, 2011 at 5:03 am | #121

      Open up Cydia, look at the top of the app, see if you’re iOS 4.1 SHSH saved in Cydia, but if you use TinyUmbrella check your iOS 4.1 (the one you want to upgrade to), did you shift + restore (on iTunes Windows) your custom firmware? I prefer you use PwnageTool to upgrade to 4.1, then use PwnageTool to make your iPhone 3G into DFU mode, don’t set the iPhone to DFU yourself, use PwnageTool or Redsn0w DFU button. Then check again your hosts file see, if it’s directing to cydia’s ip (for cydia SHSH), or 12.0.0.1 (for tinyumbrella) for host gs.apple.com.

      If you do it correctly, there’s no way you can fail, I did it tenth times, upgrade and downgrade using Cydia’s and TinyUmbrella. Check and recheck again…

    Azacode,
    I have an non-jailbroken Iphone 3Gs with FW 3.1.2 & BB 05.11 & ITunes 10.1.1 on windows XP. I would like to upgrade my FW to 4.1. I do not have the SHSH files. (As a result, trying the hosts file change with Shift-Restore from ITunes did not work). In your November 8 comment, you mentioned using Pwnage or Redsnow DFU. How would I do this, as the Redsnow instructions say to download ipsw for current version on my iphone? If I can’t install 4.1, would you recommend going to 4.2.1 as Apple is likely coming out with 4.3 soon and the jailbreakers are getting close to doing a perfect jailbreak of 4.2.1. Some of the apps (esp. printer app) I have downloaded unfortunately require IOS 4.0+, which is the primary reason for upgrading the FW.
    Many thanks for your help.

      January 6, 2011 at 5:10 am | #123

      First, if you have non jailbroken iOS 3.1.2, jailbreak it first using Spirit. Then open up Cydia, make sure it saved your SHSH, look at the top of Cydia for iOS 4.1 SHSH, if its there then you can upgrade to iOS 4.1, if not, then you’re out of luck, you should upgrade to later version like 4.2.1. If you did have iOS 4.1 SHSH on Cydia, then follow my steps to upgrde to iOS 4.1 using Cydia Signing server.

  79. Thankful
    January 10, 2011 at 11:26 am | #124

    Did the edit hosts with notepad, restarted iTunes, Shift+Restore, choose the IPSW file and it worked!

    PS: duplicate the IPSW file onto the Desktop just in case cus iTunes deletes the one in the “iPhone Software Updates” folder if you click “Restore” without holding on to “Shift”

    and thanks azacode! :)

    lonziv, if you read this, please do not put any false information regarding error 3194 to users, you took advantage of people having problems, and that is not cool, by directing them into your website. Your web won’t fix the error. And yet, you asked people to download things which is not related to error 3194, people if you are opening this web: http://www.error3194.com, please do not download anything from the website, or do not open that website, my post is not asking you to download things for my own benefits, and free of spyware, or malware homepage.

    YOU WON’T FIX DOWNGRADE ERROR BY OPENING THAT WEBSITE. AND LONZIV OR ANY OTHER PEOPLE, DON’T PUT YOUR DAMN LINKS ON MY POST FOR YOUR OWN BENEFITS, JUST BECAUSE A LOT OF PEOPLE HAVING PROBLEMS SO YOU CAN HAVE A LOT OF THEM VISIT YOUR LINK. THAT IS NOT COOL, MAKE YOUR OWN, DON’T USE MY POST.
