How To: Unlock iOS 5.1.1 On iPhone 4, iPhone 3GS With UltraSn0w Fixer For 5.1.1

May 9, 2012 by Jaden Easton-Ellett 139 Comments

Apple released the iOS 5.1.1 firmware two days ago featuring bug fixes and improvements while taking HDR photos. When the iOS 5.1.1 firmware was released we told you to stay away from updating if you relied on a Jailbreak or Unlock. Although we issued a warning, I am sure there are still a select group of people who went ahead and updated anyways.

This isn’t as big of a deal for Jailbreakers, but if you rely on an unlock for your iPhone then not being able to connect to your carrier obviously poses a significant problem. In most cases you should just be able to reinstall UltraSn0w, but because it has not been updated yet this leaves you only one other option – UltraSn0w Fixer for 5.1.1.

What UltraSn0w Fixer for 5.1.1 does is it allows you to unlock your iPhone 4 or iPhone 3GS running iOS 5.1.1 on the following basebands 01.59.00, 04.26.08, 05.11.07, 05.13.01, 05.12.01, 06.15.00. You must also be Jailbroken tethered on the iOS 5.1.1 firmware using RedSn0w 0.9.10b8b. Thus, in this how to guide from iJailbreak.com you will learn how to unlock your iPhone 4 or iPhone 3GS on the iOS 5.1.1 firmware with UltraSn0w Fixer for 5.1.1.

How To Unlock iPhone On iOS 5.1.1

Step 1: The first thing you will need to do is Jailbreak your iPhone on the iOS 5.1.1 firmware by visiting iJailbreak’s How To Jailbreak Section.

Step 2: Now you will need to launch Cydia so we can add the 3rd party repository UltraSn0w Fixer for 5.1.1 is hosted in. When Cydia is up and running go into the Manage tab, Sources section, tap the edit button and then the add button and add the following source:

http://repo.iparelhos.com

UltraSn0w Fixer Guide

Step 3: With the source successfully added you will need to simply go into the iParelHos repo section.

UltraSn0w Fixer for 5.1.1

Once you see UltraSn0w Fixer for 5.1.1 simply install it to your iPhone.

UltraSn0w Fixer for 5.1.1

 

Step 4: When UltraSn0w Fixer has been installed simply go into Cydia’s Search tab and search for UltraSn0w.

UltraSn0w Fixer Guide

After you have searched for it and see it, install it to your iPhone also and reboot.

UltraSn0w Fixer Guide

Congratulations! You have just unlocked your iPhone 4 or iPhone 3GS running the iOS 5.1.1 firmware with UltraSn0w Fixer for 5.1.1. If you are still having troubles make sure you installed UltraSn0w Fixer for 5.1.1 before UltraSn0w. For those that did it in the reverse order you will need to uninstall both packages, reboot your iPhone and follow this how to guide once again. Please leave any further questions or thoughts in the comments section below…

    I figure it out, I just erase the the 1st ultrasn0w and installed the fixer. Now It stuck on searching for carrier? Been waiting over 20 minutes, nothing?

    3 – go cydia => add repo above => install “Ultrasn0w fixer 5.1.1”
    4- install ultrasn0w
    5- go redsn0w again , select 5.1 firmware , and do Install ipad baseband

  29. Hammond Mark says

    May 14, 2012 at 11:29 pm

    Step 5 does not work for me.

    Exploiting….

    Then my phone just boots up as normal and redsnow just hangs.

  30. Hammond Mark says

    May 14, 2012 at 11:45 pm

    I’ve tried this:

    1) Install iOS 5.1.1 with iTunes
    2) Select IPSW 5.1 within redsnow, click back then
    3) Click Jailbreak 

    Exploiting limera 

    *fail*

    iPhone 3GS boots to normal unactivated state.

    Also tried

    1) Install iOS 5.1.1 with iTunes
    2) Jailbreak
    3) Ultrasn0w fix 5.1.1
    4) Ultrasnow
    5) re-install ipod baseband

    *fail*

    same thing as above.

    Followed your 5 steps on my 3GS, but still… Network status goes from ‘searching’ to ‘No Service’ and back…

    I can see Carrier 12.0 and Modem Firmware 06.15.00…

    Untill when will my/our 3GS be useless? Will we ever get the chance te heal the phone? Is there any way to downgrade to a ‘official’ iPhone as we bought it??

    Thx for reply!

    May 17, 2012 at 8:36 am

    tried with latest redsn0w also. my iPhone 3GS was unlocked b4 and the bb is 6.15.00. now after upgrading to iOS 5.1.1(my mistake), i m unable to jailbreak it. its booting to the same Activation stuff. since i don’t hv the original sim, i m unable to see further if cydia is installed or nt…ny kind of suggestion will be appreciated

  38. Us1r says

    May 17, 2012 at 8:41 am

    the installation worked very well for 3Gs BB 6.15.00 for ios 5.1.1 but for one condition you all can try it if you have problem searching issue or no service …go to settings > network > disable 3G (make it off ) after then restart (reboot) your device
    this will work with who have problems with searching issue and no service 100% worked

  39. bgf236 says

    May 17, 2012 at 10:39 am

  41. Luke says

    May 18, 2012 at 1:01 am

    Did all steps, it is showing the carrier as Koodo (which would imply it unlocked) but it is just saying “Searching…”

  42. ricky says

    May 18, 2012 at 3:54 am

    my iPhone 4 is on 04.11.08 which is jailbroken but not unlocked. does my baseband changes if I upgrade to 5.1.1 or 5.1 and unlock? Or is there any way I can change the baseband…?

  50. Fidu Didu says

    May 21, 2012 at 2:45 pm

     you perhaps did not make a custom IPSW through redsnow and restore it through itunes … make sure you do that

  51. Steph Hagarty says

    May 21, 2012 at 8:31 pm

  69. Blinkers says

    May 28, 2012 at 2:34 am

    BB 1.59.00 will only show 1 bar no matter what signal strength you actually have. The fix is to upgrade your BB but you lost the Ultras0w unlock.

  70. Reddevil01 says

    May 28, 2012 at 3:38 am

    I have a iPhone 4 ios 5.1.1 with baseband 4.12.01
    I downloaded the newly Absinthe jailbreak and then followed the steps for UltrasnOw Fixer  5.1.1 and downloaded the UltrasnOw 1.2.5 . Went through the steps as described. After all was done, phone is still locked. An awesome solution to unlock the iphone 4 with a baseband 4.12.01 has been long overdue. A little help please!!!

  86. Ntduy says

    it did not work with iphone 4s 

  87. Frankie Chan says

    May 31, 2012 at 2:17 pm

    I think when you update using Absinthe your baseband is not preserved (can someone confirm this?)

    I think the way to do it is to use sn0wbreeze to jailbreak untethered to 5.1.1 while preserving baseband, and then download the ultrasn0w fixer for 5.1.1

  88. Chester says

    May 31, 2012 at 3:59 pm

    iphone4s 5.1.1. no unlock methoed coming soon?

  89. Andrea Gouvea says

    May 31, 2012 at 4:35 pm

    I have the same baseband and had the same problem. No 3g and no service. It keeps searching forever! =(

  90. Jordtjac says

    June 1, 2012 at 2:31 am

    Guys. I had an epiphany. Those who had the push notification problem not working on iOS 5. The reason behind it is because of Ultrasn0w. Every time i did test without ultrasn0w, my push worked. but as soon as i installed ultrasn0w, they didn’t work anymore. The 5.1.1 fixer works though. I don’t know how to fix it right now.

    Yours is not one of the basebands that this fix supports. The author lists the supported baseband right in the guide. So no one should expect this fix to work unless they are running one of the few basebands that are mentioned. Friendly tip:)

  94. Liquidaze says

    June 1, 2012 at 2:00 pm

    Your baseband isn’t listed in the guide as one of the options do I don’t know why it would be a surprise. This tutorial & fix doesn’t apply to 06.15.00 or 04.12.01 for that matter.

  95. Liquidaze says

    June 1, 2012 at 2:06 pm

    Sorry, I’m wrong. I meant to reply to the 04.12.01 people having issues. 06.15.00 is one of the supposed basebands included in this fix. My apologies.

    thisis only an ultrasn0w fixer for firmwares that dos not suport direct official ultrasn0w app or repo , or for those that crush or give errors. firmware modems like 04.12.01 wont be unlock yet untill ultrasn0w or others repos will find a solution !!

    I used this method to unlock my iphone 3gs 5.1.1. I put sim card in and it said searching…or no service. I put a different sim card in and it worked like a charm. I took the first sim card and put it in my unlocked iphone 3g and it worked fine. Any ideas why the first sim didn’t work in 3gs but worked in 3g. I was hoping to use 3gs with my number and first sim but right now i can’t. Any help would be greatly appreciated. Btw thank you for all the hard work and information. Ive unlocked 10-12 iphones with your help but never ha this problem.
