Unlock iPhone 3G, 3GS and iPhone 4 without WIFI [how to]

Hi guys! There are have been a lot of requests on unlock iPhone's that do not have working WIFI. There have been a few other tutorials similar to this but often people find them very unclear and hard to work with. I will do my best to make this as simple as possible.

First of all, there are a few things we need to clear up. For this we will be using Ultrasn0w 1.2.5, this means it will be compatible with the following basebands: 01.59.00, /3GS 05.11.01, 05.12.01, 05.13.04 and 06.15.00. Your iPhone will need to be jailbroken with either Pwnage Tool, or Redsn0w, this will not work with Spirit.

Here we go.

1. Prep - You will need to download the following two files.

DiskAid (ether Mac or PC) Ultrasnow 1.2.7 deb + MobileSubstrate

2. Connect iPhone to computer using USB cable

3. Open (or your iDevice exploring software of choice)

4. Click on the folder 'Root' on the right hand side. Your screen should look the same as below.

5. Next, click on the folder 'Var' in the second window - as shown below

6. Next, click on the folder 'Root' in the next window, again shown below.

7. Then click on the folder 'Media'.

8. Next, if you have a folder named '' already in the next window, skip this step. Otherwise we will need to create one. Right click within the window and select 'New Folder'. Name this folder 'Cydia' (ensure you capitalise the C). Click on the folder you have just created.

9. If you have a folder named 'AutoInstall' already in the next window, skip this step. Otherwise we will need to create one. Right click within the empty window and select 'New Folder'. Name this folder 'AutoInstall' (ensure you capitalise the A and the I). Click on the folder you have just created.

At this step, your screen should look similar to this:

10. Great, we have now setup the folders within your iPhone. We now need to copy both the Ultrasn0w.deb and the MobileSubstrate.deb into the AutoInstall folder. To do this, simply drap them from your desktop into the folder in DiskAid.

11. Simply restart your iPhone twice and Ultrasn0w will be installed and running. (Restarting once installs Ultrasn0w, restarting a second time will start your phone with Ultrasn0w running). Insert your simcard and you will be good to go!

If you have any questions or need clarification with any of the steps, feel free to ask them below and we will answer them as soon as possible!

  • Andy H.

    Very nice instruction. I got mine iphone working like a charm. Thump up!

  • choot

    where did u get the files.

    • Abdullah

      which files u are talking about ?

  • Ovi Williams

    What if you dont have a root file?

    • http://iphoneblogr.com JaeM1llz

      Everybody has a root folder on their phone, it is part of the default filesystem. Make sure you are looking in the right place

  • Vinicius

    How will I get the Ultrasn0w file???

    It’s IMPOSSIBLE to find on the internet…

    • http://iphoneblogr.com JaeM1llz

      The download for Ultrasn0w right in our downloads section.

  • cristi

    what mean mobile subrate files that i should install with ultrasn0w ?? … i can`t find them

    • http://iphoneblogr.com JaeM1llz

      MobileSubstrate is a dependency for the ultrasn0w unlock. It will be automatically downloaded and installed when you install ultrasn0w if you don’t have it installed already.

  • yoanblue

    if i upgrade,jalbreak n unlock use redsnow and take custom firmware from snowbreeze..
    how should i do if my phone tethered?to turn on my iphone again?thx

  • Patrick

    Has there been an update for baseband/modem firmware 05.15.04?

  • Maris

    I have jailbreaked 3G Iphone 4 and also unlocked. Now how to get the WIFI.
    Still showing No Wi-FI
    Appericiate your inputs.

    • http://iphoneblogr.com JaeM1llz

      WiFi just works, you don’t need to “get wifi” maybe there aren’t any wifi networks around you.

  • clos

    did everything right still cant unlock with diskaid is there any other way to unlocke without wifi?

    • http://iphoneblogr.com JaeM1llz

      Just download Ultrasn0w 1.2 from the link above and install it following the steps listed. If you don’t have a Mac, the steps are exactly the same using SSH like WinSCP or you can use a program like iPhoneBrowser.

  • http://www.aumpro.com Pareshh Jhamnani

    Thanks buddy . . u made me very happy . . :)

  • http://iphoneblogr.com JaeM1llz

    Could you please provide us with more information about your device. Did you do a clean restore before jailbreaking? What kind of phone do you have, what firmware is it running, what baseband is it on, what tool did you use to jailbreak? Thanks!

  • anto

    i updated my iphone 3g to 4.2.1 firmware then jailbroke it and followed your instructions now my iphone is stuck with the apple logo for the past 30 mins. ps my baseband is 06.15

    • http://iphoneblogr.com JaeM1llz

      Restore 4.2.1 again and then use the latest greenpois0n to jailbreak

  • cipriutza

    iphone 3g v 4.21 bb 5.11, without wifi worked fine. Thanks

  • zaheer

    my iphone 3g 4.2.1 bb 06.15.00 wifi not connecting . help me please.

    • http://iphoneblogr.com JaeM1llz

      Please try restoring and re-jailbreaking

  • Erick

    Guys, YOU ROCK!!! I’m very happy!! At last I have my iphone working just fine thank to you. I was lost with a lot of guides about this but none of them had worked like yours. Pretty easy! Big Thanks!

  • asana

    I followed your well-designed instructions on my 3G 4.2.1 05.12.01. JB-en with PwnageTool_4.2 and with No WiFi.

    In step 10 I copied/installed ultrasn0w-1.1-1.deb and mobilesubstrate_0.9.3366-1_iphoneos-arm.deb
    Result, after two restarts I get “No Service” in the menu. Is it possible that mobilesubstrate is not a correct version? In Step 10 you instruct to copy it into the “AutoInstall” but it is not supplied / linked to.

    I would appreciate if you could give us a link to the correct mobilesubstrate.
    Also, if you, or anyone, has an idea —other than reinstalling over and over again— for fixing the No WiFi, I would highly appreciate it. Now, my phone is pretty much worthless — without Data service and WiFi.
    Thank you kindly.

  • Sierra

    Hi there,

    I followed your instructions but my Iphone 3GS is still not unlocking from ATT.

    • http://iphoneblogr.com JaeM1llz

      What part is it failing on?

  • tarunjot

    i did all the steps but unable to see the carrier option in setting

    • http://iphoneblogr.com JaeM1llz

      There is no carrier option. After you unlock you just put in your sim card.

  • Avle

    I too, follow all the instructions, and have done it a couple of times, and in my last try, it is stuck on searching… for the last 20 minutes

  • Rachit

    I have an iphone 3g 4.1 with baseband 6.15 , did the steps exactly as told but when is insert the sim my phone is stuck at searching and becomes quite sluggish
    P.S jailbroke using redsnow 0.9.6b5

    • http://iphoneblogr.com JaeM1llz

      Go into Settings>General>About to confirm that your baseband is on 06.15.00 it will be listed next to “modem firmware” then go into Cydia and go to Manage>Packages and make sure that Ultrasn0w 1.2.3 is installed. Then insert your SIM and reboot your phone, should work no problem.

      • Rachit

        When i remove the sim its shows the baseband version 06.15.00 but when i insert the sim card it keeps on searching and at that time the phone becomes very slow and in general>about tab it shows nothing in front of modem firmware nor IMEI nor ICCID but when i remove the sim the phone acts normal and shows the modem firmware and IMEI
        P.S Ultrasnow 0.93 is currently installed , first i had ultras0w 1.2.3 then also the same problem

        • http://iphoneblogr.com JaeM1llz

          Sounds like you have an incompatible SIM card. You should be using ultrasn0w 1.2.3 the latest version

          • Rachit

            yea m using ultrasnow 1.2.3 still it keeps on searching only :(

    Great work it works thanks lot my friend!


  • Sunny


    I have a iPhone 3G which is unlocked & jaibroken (Using Ultrasn0w & Cydia). My iOS version is 4.0.1 & baseband is 05.13.04. How do I upgrade my iOS version to the latest 4.2.1 & still retain the unlock. Currently, I’m also not able to use Wi-Fi from my device. Please help by providing detailed steps without dependency on Wi-Fi (or) provide me the link where I can find the details.


    • http://iphoneblogr.com JaeM1llz

      You can use Pwnage Tool 4.2 or Sn0wbreeze 2.2 to create a custom pre-jailbroken firmware. Any time you restore a custom firmware, your baseband will automatically be preserved. Thanks!

  • ashwin

    thank dud …………..it was great….

  • surya

    I have tried this couple of times but still not working.. on phone it says “Invalid SIM”.
    or not signal…any hints?

    • http://iphoneblogr.com JaeM1llz

      Turn off wifi and reboot the phone then you should get signal. If that doesn’t work try resetting network settings.

  • casio_2000

    I have a jailbreak 4.3.3 iphone with baseband 4.10.01.
    I did the trick and i still dont have any service with my sim card. So i thinks the unlock not working.
    Any help?


    • http://iphoneblogr.com JaeM1llz

      04.10.01 is not an unlockable baseband. You need to update to the iPad baseband 06.15.00 if you want to unlock.

  • EmmaNan

    THANK YOU! I wasted for too much time on other methods today once my jailbroken 3G stopped recognizing wifi after using pwnage tool. I’m now successfully connected to T-Mobile.

    Any suggestions on the wifi issue? I’ve tried airplane mode, turning wifi off and on, manual entry of networks, network reset, hard reset, all to no avail. From my research, it seems like this is a common problem after changing to BB 06.15.00 … since T-Mobile is only on 2G, it would be awesome to have wifi capability back! Any help is appreciated– my skills are mediocre at best, so nothing too fancy.

    • http://iphoneblogr.com JaeM1llz

      Is the wifi icon greyed out? It could be a hardware issue. I would be able to help more if you could provide me with a syslog

      • EmmaNan

        Not grayed out at all– it just doesn’t recognize that there are any wifi connections around, despite there being two open networks here at home that all my other devices have no problem finding and connecting to.

        I recently inherited an iMac G5 that I’m slowly getting into– what’s the best way to get you a syslog using that? Sorry for the lame question, I appreciate your help.

        • http://iphoneblogr.com JaeM1llz

          The syslog is from the phone itself. You need to install syslogd from Cydia and then send me the syslog that your phone generates. You can read more about it on Google.

          • EmmaNan

            Thanks– I’ll work on figuring this out (assuming it works similar to ultrasn0w installation as above) without wifi in Cydia and then I’ll post what I get. Appreciate the tip!

          • EmmaNan

            Alright– I’ve got a syslog for you! Do you want me to paste here or send you the text file?

    it doesnt have root folder on my diskAid.. i know it should but it doesnt. is my iphone broken?

    • http://iphoneblogr.com JaeM1llz

      The phone must be jailbroken in order for you to see the root folder.

  • kola

    i’ve done everything u said but the phone keeps showing the “searching” message… is that a network problem or did i miss something along the way???

    • http://iphoneblogr.com JaeM1llz

      It could mean that you don’t have an unlockable baseband, it could mean you have a corrupt baseband, it could mean that your carrier does not support the iPhone. We really need more information to be able to help you.

      • kola

        Well, I checked for ultrasnow in cydia and its there but its highlighted in red, does that help???

  • tompham

    I bought an used iphone 3g from craiglist this afternoon.  However, the phone could not connect to any wifi.  I couldn’t check when I bought the phone since there was no wifi available at the parking lot when we met.  Since I could have this phone connected to wifi to unlock.  Here is what I did:
    – I upgrad this 3g to firmware 4.2.1 using itunes 

    – then use redsn0w redsn0w_win_0.9.6rc16 to upgraded with ipad band from 5.15.04 to 6.15.00
    – jailbreak using redsn0w_win_0.9.6rc16 again with the above firmware (4.2.1)
    – and follow the instruction here to unlock without wifi
    – the phone kept searching for a while and finally the phone pop – ups a message saying that it was activated 

    Thank you everyone and this site!

      The SAM method was patched in April and there is no need for it on 05.13.04 baseband. If you have no signal just reinstall Ultrasn0w and MobileSubstrate and you will get signal.

      • Ddh

        Both ultraxn0w and MobileSubstrate were put into the iphone via DiskAid … nothing happened?

        • Ddh

          actually, I have one bar but cannot connect and the iphone show no network connection or carrier. It’s strange!

          • JaeM1llz

            Did you put them in the Cydia AutoInstall folder and then open Cydia to install them? Otherwise you can install them manually with iFile or via SSH.


    esta a funcionar. it’s work

    • All

      Does’nt work. I get depnedency problems for com.saur.. and ultrasn0w deb files.
      It needs the mobilesubstrate…. package first to be installed. When I try that one, it says that the com.sautik must be configured first. duh !

    • Prastha

  • mandeep

    i have a iphone 4, 5.0.2 4.11 baseband after launching tethered from redsnow and following your instructions my phone is now on an endless loop of apple icon please help

  • Tony Book

    Sweet! Thank you so much. This worked great…once I had the folders named properly. I first had the folder “Autoinstall” and nothing happened. But in rereading the post, I realized that it should have been “AutoInstall” – that capital i (I) in Install made all the difference.

  • curichin

    Hi there, I have a iphone 3g ver 4.2.1 bb 6.15.00. I jailbroke it using redsn0w and followed the above steps. In the Cydia package, the ultrasnow and mobile substrate are both installed. Does that mean my phone is unlocked? The IMEI code remains the same. I just change my carrier and no longer use this iphone 3g but hope to use it oversea. Can anyone help? Also, there’s always a message “waiting for activation”. But my phone can be connected to itunes. what does that means? Any help would be appreciated. Thanks. :)

  • Eden Prince

  • N@hAwk


    I was close to shredding my iphone after updating it to 4.2.1, baseband 6.15!

    This is what helped me:

    1) Install the files as discribed here.
    2) Check Cydia, serach for “Mobile Substrate”.
    3) If search comes up empty, google for “mobilesubstrate_0.9.3901_iphoneos-arm.deb” and install that. Reboot twice!

    hey …. i have a iphone 3g..4.2.1 on bb 06.15.00 and i followed each step clearly and it didn’t work for me … why??

  • neondelta

    you must use the right redsnow version to reflash your base band guys because sometimes it doesn’t work check first the supported version of firmware and iphone model then do it again ^_^
