How to Jailbreak iOS 5.1.1 Untethered with Redsn0w

Jun 4, 2012 - 145 Comments

Jailbreak iOS 5.1.1 Untethered with Redsn0w

The recently released update to Redsn0w 0.9.12 brings the untethered jailbreak to virtually all iOS 5.1.1 users. The latest version of redsn0w has two paths to the untethered jailbreak and which you use will depend on your iOS device, with A5 hardware being the simplest and other hardware requiring the traditional DFU mode method. Neither is particularly challenging, here they are grouped by device, the instructions below cover both.

Super Easy: iPhone 4S, iPad 2, iPad 3

Moderately Easy DFU Method: iPhone 3GS, iPhone 4, iPod touch 3rd and 4th gen, iPad 1

Note: if you are already jailbroken tethered, launch Cydia to search for and install Rocky Raccoon untether. You do not need to rejailbreak your device.

Jailbreaking iOS 5.1.1 Untethered with Redsn0w

Upgrade to iOS 5.1.1 before beginning, quit iTunes beforehand as well. Depending on hardware you may or may not need to go into DFU mode:

  • Download Redsn0w 0.9.12 (direct link for Mac or Windows) and launch redsn0w
  • Connect the iOS device to the computer and click “Jailbreak”
    • For iPhone 4S, iPad 2, and iPad 3, click “Next” and let redsn0w run the jailbreak
    • For iPhone 4 & 3GS, iPod touch 3rd and 4th gen, and iPad 1, put the device into DFU mode: hold Power button for 3 seconds, continue holding Power and now hold the Home button for 5 seconds, release Power button but hold home button for another 15 seconds>
  • Let Redsn0w run and install the jailbreak, the device will reboot itself and you will be able to find Cydia on the home screen to verify the device is jailbroken

When finished, you can reboot the device freely without having to connect it to a computer for a tethered boot. The ability to freely reboot is the primary difference between a tethered vs untethered jailbreak.

  44. n0m0n says:

    I’m not really understanding this does Redsn0w untethered jailbreak a 4s on Verizon with OS 5.1.1?
    I am reading alot of issues with Redsn0w and it appears like ppl are using GreenPoisen with positive results.
    I originally used GreenPoisen and it did jailbreak my device but I did have a few issues.
    So I was going to try Redsn0w to see it it was a better choice
    since some a$$hole stole my device and I am awaiting my replacement so a jailbreak we will go.

    Which jailbreak app is recommended?

  45. Battlesloth says:

    So question, now after succesfully completing the Jailbreak with Cydia installer present and device is rebooted with no issue:

    Problem :

    Device: iPhone 3G
    Ver : 4.2.1 (8C148)
    FW : 05.15.04

    After upgrade there is no service and and SIM will not work in device ? I have researched and fond the information on the OPTUS_AU.IPCC file which I have applied with no success ?

    What is required to have a working phone again ?

    I either get No Signal or a Single Bar out of 5 with no ability to call or recieve calls ?

    Other info point to a Band update to 6.15 but all the info say ” DONT DO IT ” or ” DO IT ” no consistant answer ?

    So how to fix ?

    Mod works and show activated but no Phone or Data on Optus Australia

    Hey Guys!!!,

    I was trying to jailbreak IOS5.1.1 for my iPhone 4s with redsn0w 0.9.12b2, Its showing error “Restore error 207: invalid password when restoring encrypted backup”…..

    Please help if somebody know what is the default password redsn0w uses to restore then I can change the same in iTunes.

    Please help………………….

  64. Jeremy says:

    Really weird. For my Verizon (CDMA) iPhone, I had to download and manually select the IPSW file in Redsn0w before starting the jailbreak. But today I decided to try jailbreaking my friend’s AT&T iPhone (GSM) and the directions were spot on…no having to manually select an IPSW file first. Can anyone else confirm this issue?

  65. raul says:

  67. jessa says:

    Hey guys i just upgraded my iphone3g to the latest redsnow, its a success but it says no service. i have tried installing, uninstall ultrasnow in cydia, reset, and all those methods but still its No service! help! maybe i overlook something or really something with my phone now after all this jail breaking stuff…please help..

    • Michael says:

      Hi Jessa,
      I jail broke my iPhone 3GS and it kept coming up with no service. What you have to do is tick the flash baseband option when you jailbreak. That should work :)

      • Johnell says:

        Hey Michael, mine keeps restarting itself, i havent even had the option do download ultrasnow yet. now that i have run redsnow and opened cydia it says preparing filesystem. im using an iphone 3GS with 5.1.1 on it. still need some help tho because im not getting past this point. Any ideas?

  68. Jeremy says:

    Ok, this isn’t working for my Verizon iPhone 4. Came from a jailbreak of 5.0.1. Restored and updated to 5.1.1 through iTunes. Put phone into DFU mode and verified through iTunes, then shut iTunes down. Ran Redsn0w as Admin and chose Jailbreak option. I’ve done this several times now…it reboots and says “waiting for reboot,” and nothing happens after that. Starting to drive me crazy. Any ideas anyone?

    • Jeremy says:

      So I downloaded the IPSW file for my phone and manually chose it in Redsn0w before jailbreaking. Then it worked. If I remember correctly, I had to do that last time with my 5.0.1 jailbreak. What the deuce? Is this something that experienced jailbreakers just know to do? Because I don’t remember that being in the directions. Or is my phone just retarded? Anyway, it’s working now.

      • Kimi says:

        I had the same problem you were having with the same phone and same company. Can you explain what the IPSW file is.?

  69. duran says:

    works 100%…

  70. adnan says:

    it worked on my iphone 3GS 5.1.1 :) thanks anyway

  71. Bader says:

    Does it really work on IPhone 3GS??? because i read a lot of it and everyone said that redsnow didn’t work on 3GS 5.1.1

  72. fiasko says:

    I am also getting Error 2000. Ipad 2 64GB.
    It gets to 89% during backup and then gives me that error and the jailbreak doesn’t complete. SOmetimes it asks me to go into DFU mode which I didn’t think was necessary anymore. It’s kind of spontaneous.
    Tried different USB slots, uninstalling and reinstalling, itunes, icloud quicktime and other apple software.

  73. keney says:

    Hi Guys !!!

  74. Duncan says:

    Hey, I downloaded the latest version of the redsnow software but after trying to run it with my iPad 3 plugged in it just throws out “error 2000”

    Im running it from my mac, any help would be appreciated.


    • tipakit says:

      From Apple support base:

      “Error 2000-2009 (2001, 2002, 2005, 2006, 2009, and so on)

      If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore. If you are using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that does not resolve the issue, try the USB issue-resolution steps and articles listed for Error 1604 above. If the issue persists, it may be related to conflicting security software.”

      Do that and also try to put the device into DFU mode before beginning next time.

  75. jbfonenidhlp!! says:

    After downloading, how to launch redsnow?

  76. jb says:

    • Stebton says:

      Restore from iTunes backup, what do you think?

      • Rooonga says:

        Same problem here with Iphone 3GS.

        Cannot restore from itunes, it will dowmload and extract the necessary files. Prepare iPhone.. and the the phone will reboot, and go into the recovery loop – showing itunes & usb lead logo.

        At this point I get the message The iphone xxx could not be restored, an unknown error occurred (21) Itunes looses its contact with the phone, and the phone cant be used at all.

        The only way I have found to get out of the recovery mode is to use tinyumberella.

        However, when I use that to get out of recovery mode, the phone goes back to it’s jailbroken state – missing almost all of the iPhone’s usual default aps, including phone, camera, maps, app store and prob many more!

  79. AjTeX says:

    Rather use Absinthe by GreenPoisen … MUCH EASIER!! & takes about 3 minutes. I Jailbreaked 4 diffirent iDevices and all JB first time without any errors!
