How To: Unlock iOS 5.1.1 On iPhone 4 And iPhone 3GS Using UltraSn0w 1.2.7 [CYDIA]

by 252 Comments

Earlier today we told you that UltraSn0w was updated to version 1.2.7 to support unlocking the iOS 5.1.1 firmware. Although we showed you how to unlock your iPhone 4 or iPhone 3GS already on the iOS 5.1.1 firmware using a hacked together version of UltraSn0w, dubbed UltraSn0w Fixer For 5.1.1, using the official solution is always a better idea as it is more stable and reliable. Thus, in this how to guide we will show you how to unlock your iPhone 4 or iPhone 3GS running the iOS 5.1.1 firmware using UltraSn0w 1.2.7.

UltraSn0w 1.2.7 Supported iPhone Basebands 

  • iPhone 4 on baseband 01.59.00
  • iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00

*In order to see if you have one of the supported basebands on your iPhone 4 or iPhone 3GS you will need to go into the Settings.app > General > About and look for the Modem Firmware field.

How To Unlock iPhone With UltraSn0w 1.2.7

Step 1: You must already be running the iOS 5.1.1 firmware on your iPhone 4 or iPhone 3GS, and you must also be Jailbroken on the iOS 5.1.1 firmware. If your iPhone is not Jailbroken please click here.

Step 2: After your iPhone is running the iOS 5.1.1 firmware and is Jailbroken you will need to simply launch Cydia from your SpringBoard.

Step 3: Once Cydia is up and running you will need to go into the Sources page. To go into the Sources page tap Manage followed by Sources.

Step 4: Typically, the UltraSn0w repo is included with Cydia. If not, tap the Edit button followed by the Add button and you will be prompted to add a URL source. Type:

http://repo666.ultrasn0w.com

Followed by tapping the Add Source button.

Step 5: Cydia will automatically refresh and update sources.

Step 6: After Cydia is done refreshing sources. Tap the Search tab on the bottom tab bar and search for UltraSn0w. Once UltraSn0w appears, tap on it and you should see version 1.2.7. Read through the description and tap the install button to install UltraSn0w 1.2.7 to your iPhone 4 or iPhone 3GS  running the iOS 5.1.1 firmware.

Note: In case you are not familiar with UltraSn0w, it is a software unlock for your iPhone meaning you can use your iPhone with any carrier by simply inserting the SIM card.

Ultrasn0w 1.2.7 iOS 5.1.1 unlock

Step 7: When UltraSn0w is installed you must restart your iPhone, plug in your unofficial SIM card and wait for your iPhone to connect to your network.

Congratulations! You should now have an unlocked iPhone 4 or iPhone 3GS running the iOS 5.1.1 firmware. If you have any further questions or thoughts please leave them in the comments section below.

    You need to search for “update iphone 3gs basedband to 6.15.00” it’s going to be either pwange or redsnow will give you the ability to get this done & then ultrasnow will give you the ability to unlock your iphone. Good luck. 

  7. Campflo says

    Keep looking for sam to become available again or get a gevey sim. I have used one in the past but I went & did an update & lost that ability but was lucky enough to catch the sam unlock so I’m ok again. Good luck. 

  9. Gadalla97 says

    Now i want to upgrade to iOS 5.1.1 without changing the Baseband.
    Please help

  14. V O N N I E ™ says

    Since there is no unlock for BB 4.12.01, how can we downgrade it back to 01.59.00? then be able to preserve it then upgrade back to the 5.1.1 with the preserve 01.59.00 to be able to follow this step? Help!!

  15. Rahul Bagga says

  16. Penishead65 says

  20. Kevin says

    It deosn’t still work for my iphone 3gs. Searching…. for signal still there.

  22. Zuramachavariani says

    iphone 3gs ios5.1.1 jailbroken untetherd baseband 06.15.00 serching ,serching, serching 5 minute and than no servise. help please?!

  25. Ron says

    here too 3GS with old bootrom baseband 6.15.00 ultrasn0w totally fucked and not working.. please roll back to the previous version so i can get my two phones going again.

  27. boroda says

    Reflash your phone with iTunes. Then, using redsnow select 5.1.1 ipsw and click jailbreak. Check install cydia and install ipad baseband. And next use this instruction to unlock with ultrasnow.

  28. Trevy gunz says

    iphone 3gs 5.1.1 bb 6.15.00. did everything as per this post. DOES NOT WORK!! 

  30. Freddie Jarrett says

    for everyone having the problem saying searching… I was too and tried everything i could find and then i just tried making a call. it didnt go through but after it recognized the sim. So just try to make a call.

  31. Eric Hennig says

    k so like i have firmware 06.15.00 and my firmware is 5.1.1 but my service still just says searching, any adivice or help?

  33. Guru says

    Amjad…restore the 3GS with 5.1.1 custom OS built using Sn0wbreeze expert mode. In expert mode do select general option and in that select the check box for hactivation.

  34. Guru says

    First check the manufacturing date of your 3GS. It should not be greater than 2011 and 28th week. If it is greaten than 2011, 28th week, then please do not use ipad baseband 6.15.00. It will damage your 3gs permanantly. You can find this by checking the 3rd, 4th and 5th digits of the serial number. 
    if the digits are 129 means. 1 stands for 2011 and 29 stands for 28th week.Another example 045, 0 stands for 2010 and 45 stands for 45th week.

  36. Syed200 says

     I had the same problems with my 3gs on bb 6.15.00 and this worked to resolve the problem I was having with the unlock

  38. Sauravp95 says

    not working for my iphone 3gs . Modern firmware – 06.15.00 and ios 5.1.1 . my location – india .
    bought my iphone from the U.S.A

  41. Calvin says

    After jaibreak apparently successful, I tried unlocking iPhone 3gs following your instructions above and it did not work. I am using baseband 06.15.00 running iOS 5.1.1  – My iphone was just fine before restoring contacts using iTunes back up – Looks like it updated/upgraded the software and after that, my phone was locked again… I have looked everywhere online. This is the third time that I try unlocking using ultrasn0w – 1.2.7 and its fixers available online…  Can anyone help solving this mistery? Thank you.

    E-mail me: email2cal@gmail.com

  42. Dgeedubz says

    also try using redsnow, then go to extras then customer ipsw it will create one with no baseband then carry on as usual

  43. Dgeedubz says

    iphone 3gs jailbroken on ios 5.1.1 with bb 06.15.00. this is disappointing after finding out the dev team had done a great job with updating redsnow, i try it and this happens. please dev team can you fix this error or at least make it public that it does not work on some devices, THANK YOU very much otherwise BUT please if some one finds out how to fix this searching searching searching… no service problem please let us all know 

  44. mmm89 says

    The same thing for me… iPhone 3GS, iOS 5.1.1, BB 06.15.00 and not working the ultrasn0w unlock… searching, searching, and nothing… Please update!!! 

  46. Lawmanf5 says

    i just cut my t mobile simcard put it in and when i turn it on it says no sim, so does this mean im screwed and dont have a phone now?!

  47. hwgomez says

    I did all process, and i have the baseband 06.15.00, but the sim card no service

  49. Ggsgdgd says

    this worked for me as well. i tried everything. jailbroke and restored 5 times before i saw your post. finally it worked. thanks

  50. montassar abidi says

    unfortunately, i have an iphone 4 with baseband 04.12.01, there is no any solution to upgrade baseband or downgrade it ?

  52. Puneet_relhan86 says

    Using Iphone 4 having iOs 5.1.1 having baseband  4.12.01 but after above steps my iphone is showing invalid sim. 

  53. Rizzlat says

    Is there something wrong with ultrasn0w 1.2.7 on BB 06.15.00?
    Does not work…….

  55. Duy Tran says

    Iphone 3gs 5.1.1 unlock with redsnow 0.9.10b6 and used 5.1 firmware, untethered with rocky racoon 5.1.1 and already install ultrasnow 1.2.7, it keep searching but no service

  60. Naija says

    I have tried to use it, but it does not get installed fully on my iphone 4s (5.1.1) which is already jailbroken. When i install ultrasnOw, it runs a script with two red errors at the bottom. The the phone gets springboarded and it asks me to forcibly remove ultrasnow.

    So how do i lock the iphone 4s which has already jailbroken?

    ( i have already tried using gaveys sim method and that dosnt work as the iphone 4s gets locked again and again)

  63. MikeyUM says

    Download redsn0w 0.9.14b1 then do jailbreak method, and select instal iPad baseband, after you have install they your BB will be 06.15.00, then do again jailbreak and now you can select downgrade baseband and you will have now the BB 05.13.01 and now in cydi just install ultrasn0w and your all set up

  65. Xxdaamx says

    you can place the cut simcard in your previous phone by putting back the parts that you cut out in the simcard tray, that worked for me 

  66. Dustybee says

    Please help!!!!!
    I got a 3GS from a repair shop that lost my phone when it was there for repair. They told me it was jailbroken and unlocked only when I got it, it still had someone else’s info in it and when I used my Fido card in it, there was no service. It was still showing in the about section the original. I then nOticed that it was on the BB 06.15.00. I restored the phone with redsnow Pwnd Dfu and restored to factory firmware 5.1.1 with iTunes and jail broke, still no service using ultrasnow 1.2.7. I then got the new redsnow and jailbroken with the iPad baseband, no service. I then downgraded the baseband to 05.13.04, no service. I created a custom ipsw with redsnow to preserve my baseband and entered Dfu restored with my custom ipsw in iTunes, no service. Most recently I restored back to a factory 5.1.1 baseband 5.16 and jailbroken with cydia, ultrasnow and ultrasnow fixer, no fn service.
    Is this phone bricked or is it possible I have missed something in the last 2 weeks
    Pls help
    I phone 3GS old bootrom (920)
    Currently on 5.1.1 bb 05.16

  73. Phonetech1985 says

     try opening the iphone and check next to the antenna connection on the right bottom corner the connector is a flex cable remove the flex cable when you are finished removing the cable there should be about 3 diodes next to the antenna connection on the mother board if one is missing just replace it or connect the 2 pins there where it is missing with a small piece of soldering and that will solve the problem other wise if that is not the problem check the phone and see if either the wifi bluetooth or imei number is missing meaning the baseband has been damaged and needs replacing let me know if this helps

  79. Meektown says

    Hello

    I have my baseband preserved on 01.59.00 and I am currently on iOS 4.0.1.
    Previously I was unable to update and then unlock. With this new realease of UltraSn0w, will I be able to finally upgrade?

    Thanks DEV Team for all that you do!

  82. ssnowflake says

    Would I be able to hook this up to Virgin Mobile in the US? They don’t use sims, would that be a problem?

  83. Broncologist says

  115. Anonimo says

    I had the same problem. 

    With RedSn0w, install again baseband 6.15.00 (This is the trick, install again ipad baseband 6.15.00). Then install Ultrasn0w fixer for 5.1 and finally Ultrasn0w.
    It works like a charm. I have an iPhone 3GS 5.1.1 with ipad baseband 6.15.00 and works perfect, with ultrasn0w 1.2.7.

    Sorry my english.

  125. Pavan says

    I had the same problem , it used to say Searching ,searching but now it got resolved
    .
    I have Iphone 3GS, 6.15.00 BaseBand. as per the 1st step I have used original itunes 5.1.1 ipsw to restore but some sites have suggested creating a custom ipsw using redsnow. I  have not done that the first time but my BaseBand was still 06.15.00 after the restore and jailbreak.
    However downgrading my baseband from 06.15.00  using redsnow Ipad  baseband option.
    my baseband is now 05.13.04

    I have used just the UltraSnow 1.2.7 and thats it. Ultrasn0w fixer for 5.1 is not needed.
    And soon after it recognized my service.

    Thank you Jaden, the article is really good.

  126. Pavanb_4u says

    I had the same problem, try downgrading your baseband using redsnow , it worked for me. I used to have the same 06.15.00 and I have downgraded it using redsnow . it worked like a charm

    Quick question. What do you mean by “Plug in your unofficial sim card” ?
    I thought that you cant take out the backing of an iPhone so how would the sim card be replaced?
