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 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 'Cydia' 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!

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

  2. choot says:

    where did u get the files.

  3. Ovi Williams says:

    What if you dont have a root file?

  4. Vinicius says:

    How will I get the Ultrasn0w file???

    It’s IMPOSSIBLE to find on the internet…

  5. cristi says:

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

    • JaeM1llz says:

      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.

  6. yoanblue says:

    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

  7. Patrick says:

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

  8. Maris says:

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

  9. clos says:

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

    • JaeM1llz says:

      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.

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

  11. JaeM1llz says:

    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!

  12. anto says:

    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

  13. cipriutza says:

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

  14. zaheer says:

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

  15. Erick says:

    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!

  16. asana says:

    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.
    asana

  17. Sierra says:

    Hi there,

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

  18. tarunjot says:

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

  19. Avle says:

    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

  20. Rachit says:

    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

    • JaeM1llz says:

      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 says:

        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

    lot!

  25. Sunny says:

    Hi,

    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.

    Thanks…Sunny

    • JaeM1llz says:

      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!

  26. ashwin says:

    thank dud …………..it was great….

  27. surya says:

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

  28. casio_2000 says:

    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?

    thanks

  29. EmmaNan says:

    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.

    • JaeM1llz says:

      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 says:

        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.

        • JaeM1llz says:

          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 says:

            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 says:

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

  43. kola says:

    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???

    • JaeM1llz says:

      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.

  44. gihan0081 says:

    my iphone 3g 4.2.1 i have base band upgraded 6.15 by using redsn0w 0.9.6b5..also then i re-jailbreake my i phone by using redsn0w 0.9.6rc16.. then i tried today to unlock by using ultrasn0w without using wifi ( my wifi service on the iphone dose not work)..

  64. tompham says:

    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 
    http://www.iclarified.com/entry/index.php?enid=750

    – then use redsn0w redsn0w_win_0.9.6rc16 to upgraded with ipad band from 5.15.04 to 6.15.00
    http://uploading.com/files/ecam8913/redsn0w_win_0.9.6rc16.zip/
    – 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!

      04.10.01 is not compatible with the Ultrasn0w unlock. You will need to buy a Gevey SIM if you wish to unlock.

      As long as you have an Ultrasn0w compatible baseband you can use the 5.1.1 Ultrasn0w fixer found here: http://iphoneblogr.com/2012/05/unlock-with-ultrasn0w-on-5-1-1-with-ultrasn0w-5-1-1-fixer-deb/

    All of this tutorial is the right things we have to do to desimlock a iphone on USB, no wifi cos no network, so no SSH.

    In cydia can see ultrasnow installed but with a row color a few pink, seem is getting a problem.
    Any idea of this particular problem.

    Many thanks.

    Thank You It Worked like charm….

  99. Ddh says:

    Did the process … came down to 5.13.04 … and still no signal?  Running version 4.2.1 on G3.  I wonder if I can install SAM via this same method and if so, where does it go in the packaging system?  Does it go in the same place as the MobileSubstrate.deb and ultrasn0w 1.2.7.deb folders do on this process?

    • JaeM1llz says:

      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 says:

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

        • Ddh says:

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

          • JaeM1llz says:

            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.

      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 !

  122. Tony Book says:

    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.

  123. curichin says:

    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. :)

    THANK YOU MAN!!!!

    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!

    Done!

  135. 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??

  136. neondelta says:

    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 ^_^
