How To Jailbreak iPhone 4, iPhone 3GS Running iOS 5.1 Using Redsn0w

Jailbreak iPod Touch On iOS 4.2.1 Redsn0w

Apple released iOS 5.1 yesterday, which includes some minor improves and bug fixes.

iPhone Dev team has just released a new version of Redsn0w – Redsn0w 0.9.10b6 that supports iPhone 4iPhone 3GSiPad 1 and 3rd-generation and 4th generation iPod touch.

But if you accidentally upgraded to iOS 5.1 (don’t update to iOS 5.1 if you are on iOS 5.0.1 or lower) and want to jailbreak your iPhone 4 or iPhone 3GS then you’ve come to the right place. We will take you through the step by step procedure to jailbreak your iPhone on iOS 5.0.1 using Redsn0w.

Here are some important points to note before you proceed.

  • This guide is meant for iPhone 4 and iPhone 3GS users. iPod touch 4G and iPod touch 3G users can checkout this guide, while iPad users can checkout this guide.
  • Important note to iPhone unlockers: Please don’t use this guide if you want to preserve your iPhone’s baseband.
  • Redsn0w 0.9.10b6b for Mac and Redsn0w 0.9.10b6b for Windows only supports a tethered jailbreak, which means that you need to connect your iPhone to the computer on every reboot (except iPhone 3GS with older bootrom).
  • Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution and at your own risk.
  • Please do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.
  • If you’ve jailbroken your iPhone then you can use jailbreak apps such as PkgBackup from Cydia to take a backup of all the jailbreak apps and tweaks so you can reinstall them easily after successfully jailbreaking your iPhone rather then installing them individually. However, if you’re moving from iOS 4.x to iOS 5, it may be a good idea to reinstall the jailbreak apps to avoid compatibility issues.
  • After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPhone secure.
  • Please ensure you are running latest version of iTunes i.e. iTunes 10.5 or later.
  • Known issue: iBooks won’t work if you jailbreak your iPod touch using Redsn0w 0.9.10.b6. Dev team is working hard to fix the issue.

You can follow these step-by-step instructions to jailbreak your iPhone 4 and iPhone 3GS with the assumption that you’ve already updated your iPhone to iOS 5.1 (please note Settings –> General –> About –> Version should be 5.1):

Step 1: Download Redsn0w for Windows from this link and Redsn0w for Mac from this link and save the application in a folder named “Redsn0w” on your desktop.

Step 2: Double click the Redsn0w zip file and extract the application to the Redsn0w folder. Navigate back to the Redsn0w folder and launch the Redsn0w application.

Step 3: After launching Redsn0w, click on the Jailbreak button.

Windows 7 users should run the exe in Windows XP compatibility mode (right-click on the Redsn0w exe and select Properties, then select the Compatibility tab and select Run this program in compatibility mode for Windows XP). Windows XP and Windows 7 users should run Redsn0w as ‘Administrator’ (right-click on the Redsn0w exe and select ‘Run as an Administrator’).

Step 4: You will now be prompted plug your iPhone to the computer and switch it OFF. Follow the instructions and click on ‘Next‘ to move to the next screen:

Step 5: You will now need to put your iPhone into the DFU mode. Redsn0w will take you through the necessary steps:

(a) Hold the Power button on iPhone down for 3 seconds:

(b) Now simultaneously hold the Home button and keep the two buttons pressed for 10 seconds:

(c) Now release the Power button while keeping the Home button pressed until Redsn0w detects the device:

Step 6: Your iPhone should reboot now. Please remember to release the Home button.

Step 7: Redsn0w will now start preparing the jailbreak data.

Step 8: You will now be prompted to select the jailbreak options you would like. Make sure Cydia is selected and select ‘Next‘ to continue.

Step 9: You iPhone will be rebooted again and Redsn0w will now begin uploading the new RAM disk and kernel.

Step 10: You will now be notified once the jailbreaking process is complete. Click on the ‘Finish‘ button to exit the application.

Step 11: Your iPhone will reboot once again (which could take approximately 5 minutes). After it has rebooted, your iPhone should be successfully jailbroken. You should find Cydia jailbreak app on your iPod touch’s home screen.

If you’re new to the jailbreaking world and wondering what to do after jailbreaking your iPhone, checkout our jailbreak apps category page to find out the apps you can install on your iPhone using the Cydia app. Please note that some of the jailbreak apps and tweaks may not be compatible with iOS 5.1 so please be cautious while installing them.

Tethered Jailbreak:

Once Redsn0w has finished jailbreaking your iPhone, you will need to boot it tethered, which means that if you need to reboot your iPhone it will be stuck on the Apple logo. All you need to do is rerun Redsn0w and this time click on Extras and then click on Just boot from the list of options and follow the on screen instructions to reboot your iPhone.

Troubleshooting:

How to fix the White/Blank Cydia icon issue:

If you notice the white Cydia icon (which fails to launch) after successfully jailbreaking your iPod touch. Then follow these steps to fix the issue.

  • Launch Redsn0w again.
  • Click on Extras and then click on Just Boot from the list of options.
  • You will now be prompted to plug your iPhone to the computer and switch it off. Follow the instructions in the correct sequence and click on ‘Next‘ to move to the next screen:
  • You will now need to put your iPhone into the DFU mode. Redsn0w will take you through the necessary steps:
    • Hold the Power button on iPhone down for 3 seconds.
    • Now simultaneously hold the iPhone and keep the two buttons pressed for 10 seconds.
    • Now release the Power button while keeping the Home button pressed until Redsn0w detects the device.
  • Your device will reboot and you will see the Pwnage icon on your iPod touch’s screen for few minutes.
  • After your iPhone is successfully rebooted, you will see the regular Cydia icon (brown). You should now be able to launch Cydia without any issue.

Hope this helped. Please don’t forget to let us know how it goes and feel free to drop us a line if you hit any issues.

Update (April 15th, 2012):

Dev team has updated Redsn0w to 0.9.10b6b to fix an issue affecting those users running OS X 10.5.x or earlier. So we have updated the download link.

    After that long wait for a jailbreak on ios5(5.0/5.0.1) I don’t think anyone is dumb enough to upgrade to 5.1

    • http://www.motorbeam.com/ fas

      Well people do it accidentally.

    • http://www.iphonehacks.com/2012/03/jailbreak-iphone-4-iphone-3gs-ios-5-1-using-redsn0w.html Dan

      Hi. So I finally was able to jailbreak my iphone 4 but the only problem is that the cydia icon is white. I followed the directions for redsnow to boot just tethered right now but it gets to the part where its waiting for reboot and my phone reboots but redsnow seems to not notice it and then it just stays at the waiting for reboot till I have to cancel it. Please let me know what I can do

      Thank you

      • Harun

        Hi,
        im afraid you have to restore your your device, in order to restore you have to hold down the power and home button together untill it shows the itunes logo, and then plug your device into the computer and then on itunes hit restore and update

      • mark

        You have to start the iphone 4 using the cydia application. You need to open cydia, use extras, and reboot. IT worked for me.

    • YouLethal

      Heya, Any reason why my Iphone 3gs running on ios 5.1 is jailbroken untethered? I can turn it off and on as I like without having to boot from redsnow. I don’t have semi-tether installed either?

      • Paul

        You must have an old bootrom 3GS. The jailbreak is not tethered for this device. Google 3GS bootrom to find out how to check your bootrom if you so incline.

    • tmartin

      i tried doing this jailbreak, it all seems so familiar but my phone was stuck on the initial startup and i cant get passed the “activation” process, it keeps telling me (no matter what kind of sim card is in there) that it is temporarily unavailable.. is this a phone problem or apple problem!?

    • Lala

      Yeah, I accedently updated to 5.1 is there any way I could possibly go back to 5.0.1?

    • Siraj

      While running the app getting an error that ‘Certain operation (like the A5 jailbreak) are disabled due to incomplete iTunes libraries please be sure that latest iTunes is installed. could not load mobiledevice.dll. I have the latest iTunes installed. Can anyone please solve the problem.

      • NAINOAH

        USE ANOTHER COMPUTER. IT WORKED FOR ME AFTER GETTING SAME ERROR.

  • jOE

    so here’s what happened. yesterday i tried to restore my unlocked 3gs with custom 5.0.1 firmware i created with sn0wbreeze and at the verifying firmware with apple i got an unknown error (6). The phone is now stuck at restore mode. I tried to kick it out of restore mode using the restore fix in redsn0w without luck. i then tried to restore using the custom 5.1 firmware created with redsn0w that just been released. Itunes can’t get pass the verifying process after extracting the file and gives me unknown error (3194). Is there any help??? TIA

    • http://www.iphonehacks.com/ iPhoneHacks

      Check your host file entries and comment anything with *.apple.com as it looks like your computer is pointing to Cydia servers or the other option is to try it on another computer ideally that hasn’t been used for jailbreaking.

      • Joe

        Thanks for the reply but what do you mean by comment anything with *.apple.com? And how do I check for the host file entries? I may try again using different computer today. But if you can elaborate more on the first option that would be great. Thanks again

        • paul

          If you have tiny umbrella installed on your computer, open it and click on Advanced tab. Uncheck “set host to cydia on exit”. Apply changes and reboot computer. You can now restore to 5.1

          • Joe

            Many thanks for the tips paul will give it a rum when I get home from work.

          • CESAR

            OK SO I KEEP HAVING THE SAME PROBLEM JOE DID, AND I KEEP GETTING THE SAME RESULT. I’VE TRIED SEVERAL DIFFERENT DOWNLOADS OF “R.S” AND IT ALWAYS CRASHES WHEN I GET 3 BARS ON THE KERNEL STAGE. I DID THE BLACK/WHITE FROZEN TIP AND THAT GOT ME TO “PATCHING FILES” THEN IT CRASHED. I’VE TRIED “IFAITH” AND IT TELLS ME NOT “ELIGABLE” SINCE MY 5.1 IS A STOCK UPDATE. “S.B.” SAID ITS NOT FOR THE IPHONE 4 (CDMA) I USED UMBRELLA BUT I DON’T SEE ANY BUTTON FOR “APPLY CHANGES”. AM I SUPPOSE TO JUST EXIT AND RE-START MY CPU? CAN SOMEONE PLEASE HELP I’VE SEEN TRYING SINCE THE NEW “IOS” WAS RELEASED. THANKS

      • JOe

        this is what in the host file
        #74.208.10.249 gs.apple.com
        #127.0.0.1 gs.apple.com

        can you please help me?

      • JOe

        after followed the 2nd method (used a different comp) i was successfully update my phone with the custom firmware keeping the bb and now waiting on the update of ultrasn0w thank you iphonehacks and paul

    • George

      Download iREB and run it

  • Axe

    I really hope this 5.1 solves the calling audio bug. It’s damn frustating.

  • Lahey

    No untether = no jailbreak for many.

    It’d be interesting to see how dependent sales on Cydia are on a truly reliable untethered jailbreak. My guess is fewer are bothering to spend money when they have only a tethered jailbreak. It has to come down to money at some point; money changes everything.

    Unless an untethered jailbreak is released I can’t imagine developers would take the time to release something via Cydia.

  • Rey

    i custom restored my iphone 3gs to IOS 5.0.1
    and jail broke it using the latest version of redsnow (0.9.10b6)
    once i put my tmobile sim card into my phone, it doesnt connect to any network
    instead it just tells me that it is ” searching..”

    when i try to select a carrier, it tells me “unable to load network list”
    i would greatly appreciate some help or atleast some advice on what i could to to get my sim card to be read..

    modem firmware: 06.15.00

    • JOe

      i believe that you have to wait for the the update of ultrasn0w because its recent version is not for 5.1 but only support up to 5.0.1. If what mentioned in the other post is correct, new version of ultrasn0w will be released in a few days

    • harshdeep singh

      dude,try the process again while your sim is already in the phone

    • Ali Kilic

  • carla

  • Ashley

    After installing THE jailbreak safari stopt working! So i thought that it would help if i resore my iPhone 4 ! Bute after restore safari still doesnt work and also THE Cydia icon is still on my screen but wont open!

    Could you please help me ?

    • Retribution1888

      Not 100% sure but I think You may have ro reinstall cydia! As I have restored your iPhone to a previous sync

    • Olaf

      You may need to run Redsnow and choose the option to Just Boot.
      Since it’s a tethered JB, that is necessary.

      • Olaf

        Just to add, Redsnow tells you after you JB that you will have go through the Just Boot process. Then Cydia and everything else should work. It did for me and always has in a tethered situation.

      • Max

        Hey, I’m having the same problem and I used redsn0w and used the boot tethered, cydia works fine as does everything else, just no safari. I tap the icon, the loading screen thing comes up, and then instantly dissapeares. Any help?

    • http://www.iphonehacks.com/ iPhoneHacks

      You need to ensure there is no host file entries pointing to Cydia (check etc/hosts).

      • Raymond

        Hi, I upgraded iso 5.1 to my iphone 4 and download redsnow 0.9.10b6b in my mac osx n performed jailbreak tethered.
        Somehow there is no Cydia but somehow the jailbreaked apps are workable.

        So , my question is, based on your comment, for deleting any apps entries pointing to Cydia, may I know how o check in myiphone if there is any remaining file / apps in my iPhone from Cydia ? PLEASE HELP !

  • Mohammed

    I got this message on Cydia ( this device is in the pending TSS queue ) . The jailbreak is ok and finish but still got Message No service . What i can DO Now ?

  • harshdeep singh

    hye, i hav iphone 3gs . i followed instructions and went well until redsn0w said ‘the rest of the process will be done on phone’ n ‘done’ option bt then my phone got swicthed on n da ‘finish’ dint appear on the application and my phone is working well bt version is still 4.1

    • http://www.iphonehacks.com/ iPhoneHacks

      Hey Hardeep,

      The assumption of this guide is that you’re on iOS 5.1. So if you’re on iOS 4.1, you will need to update to iOS 5.1 and then use this guide. But before you upgrade you need to remember that this is a tethered jailbreak so you will need to connect your iPhone to the computer for every reboot (using Redsn0w). This guide is also not meant for unlockers so don’t update to iOS 5.1 if you care about software unlocking your iPhone.

      • Martin

        Ey my phone is updated to v 5.1 so can I follow the instructions to jailbreak my iPhone 4? I have a great amount off apps on my phone which I bought on iTunes will I need to redownload it through the jailbreak store?

  • cynara

    i am trying to download red snow and it keeps saying safari can’t open it because no application is available to open it… i am simply trying to re-install the cydia app on my phone it was deleted but my phone is still jail broken … please help i an extremely aggravated and ready to throw my phone out the window… what am i suppose to d

  • bubba

    ok so i just updated to 5.1 and jailbroke using redsn0w 0.9.10b6, and everytime i try to boot up (with it connected) it says “couldn’t download required IPSW! Please check your internet connection. If your internet is working, you may need an updated version of redsn0w. Error with SHSH blobs!”

    idk what to do now ive tried multiple times and im not very tech savvy so im lost.
    Please help

  • Dan

    Hi,

    I upgraded my 3gs newer bootrom to 5.1 today and now it’s stuck in restore mode loop.
    I’ve tried jailbreaking it but the jailbreak hangs on the black and white text with the full screen showing multiple lines of ‘Please wait…..’
    Also, when trying to restore in itunes I get error code 40 or more recently error 3194.

    Please help.

      Download and open the latest version of TinyUmbrella (v.5.10.08). Start TSS SERVER on it before going through the jailbreaking process. Rejailbreak. Let me know How it work for you!

  • Tom

    Hi guys, I stupidly updated to 5.1 so I’ve followed the above instructions, two problems for me here:
    1: Open Redsn0w and get the message:
    ‘Incomplete iTunes Libraries, Couldn’t load Mobiledevice.dll’.
    2: While ignoring this message and carrying on, the latest version of Redsn0w will not recognise my phone in DFU mode whereas older versions do recognise it, however useless as 5.1 will not work with older versions.

    — I’ve re-installed iTunes (latest version) twice and also downloaded a slightly older version to try.
    — I’ve re-downloaded and re-installed Redsn0w twice however the same error message is coming up.

    — Just need to mention, I have jailbroken before a few times, I’m not new to it and I know how it all works, I’m just having trouble getting past that said error message.

    Thanks in advance.

    • Phil

      Hey Tom,

      I’m a neaby at all this, but I have the same problem has you. Did you solve your problem, and if so would you share it with me??

      Thanks!

      • fais

        hey guys any solution to your problem yet ? i am stuck at the same stage with library files error from red snow

    • khah

      Download iTunesMobileDevice.dll from a site on google.

      Extract it into desktop

      Rename it by right clicking it and left clicking rename Rename it MobileDevice.dll

      Place the file after renaming it into the folder that need’s it. (In my case I needed it in the Redsn0w folder in order to use it.)

      Let me know if this helped you!

  • Yasir

    Ihave updated my iphone 4 to 5.1, when i launch redsn0w 0.9.10b6, it shows an error “Incomplete iTunes Library

  • Falahuddin

    Hey guys..!..I am updating to ios 5.1. I tried updating to 5.0.1, but it was hard with itunes to upgrade to something which was not the latest update. Anyways, Now i have updated successfully, and its time for jailbreak. The 1st problem i face is that i cannat pass the activation screen. If i try to call the emergency number, the call drops. And second, I am unable to put my phone in DFU mode (though i have done it before many times). The redsnow doesnt recognize the phone, while itunes does.

    Help me out of this please..
    Thank you all..

    • Nathan

      What you need to do is put your ipod in dfu mode, open redsn0w, and click “Extras”. Then click “Select IPSW”. (On Windows 7) Select your ipod restore data from: C:/Users/(your username)/AppData/Roaming/Apple Computer/iTunes/iPod Software Updates. If you are running ios 5.1 it should be called Ipod4,1_5.1_*****_Restore.

  • Monish

    Unlocked iphone 4 with ios5.0 using redsnow. Then unlocked using SAM. All was well till i downloaded some cydia apps. Then after a tethered reboot, phone restarted in safe mode and so i deleted all the cydia apps i had downloaded.
    However, the cydia icon disappeared and phone remains in safe mode despite rebooting via tethered redsnow.
    Can someone advise what to do?
    Tks

    • Monish

      Jail broke with redsnow and unlocked using SAM.

    Hey guys can someone please help me, i followed the steps as explained above ba it still says no service i dont know why, Am in The Gambia, West Africa hope it works when am here……..And am having an iphone 4 wiv ios 5.1…Thnx

  • Anish

    I accidentally installed ios 5.1 over ios 4 on my iphone 4. Now when I try to jailbreak using redsnow it is not able to unlock the phone. It gives me “No service” error. How do I actually unlock the iphone 4 with ios 5.1 on it. I could not retain the baseband either. So it changed to 4.12.01. Now I know how to do this upgrade by retaining the baseband but its too late for my case. Any suggestions?

    I jailbroke a 3g last year with no problems, and tonight tried to jailbreak a 3gs. Everything went fine, but when I tap on the Cyndia icon, it spends a ton of time “loading” and then times out. This happens with any app I try to access. Any ideas?

  • sisla

    I have an iPhone 3GS on firmware 4.0.1, jailbroken, old bootrom, bought from Apple, so unlocked.

    I want to update to 5.1 so I can use iCloud etc but I can’t manage this through iTunes. I keep getting an error 11.

    Any ideas out there please guys & ladies as I’m completely lost?

  • tom

  • Dipesh

    i had jailbreak my iphone 3gs with ios 5.1, i dont know the baseband (where to find baseband of my iphone). after successfully jailbreak i had to reboot with redsnow, if i would not use redsnow for reeboot my iphone jb apps dont work, is there any solution for it

  • Megan

    When will redsnow come out with an update for the 5.1.1 ipod update? Because for some odd reason now that i updated thay version from itunes it will not even show cydia even after I tried doing it tethered. Is there something Im doing wrong? Thanks

  • dre

    I’m having a problem with my jailbreak for my itouch 4g. I can get it t to jailbreak properly with the 5.1 iOS with .9.10b8b redsn0w and got it to work for my uncles iphone 4 and my bro’s ipad, but for some reason after jailbreaking my itouch i can’t reboot it tethered. Clicking “Just reboot” on redsnow goes smoothly right until it needs to reboot. Instead of booting up with pineapple it boots with apple then precedes to go straight into recovery/restore mode. I know i’m putting it in DFU mode correctly, otherwise the reboot wouldn’t even start on redsn0w. I’ve also tried the hard dfu mode and reg dfu mode, both give same results and i JUST did it for my uncle again and had no problem with his phone.

  • cr8tivegal

    I jailbroke my iPhone 3gs, (ios 5.01) used Ultrasn0w to unlock it but the Carrier name remains the same I am in Canada and the Carrier still shows “Rogers 11.0″ is this correct or was the unlock not successful, does anyone know the answer I have invested way to many hours already trying to get this to go. Thank you in advance!

    Hello. Im using an unlocked iPhone so that I can use with Movistar. What baseband does this version of Redsn0w have? Or how can I jailbreak my iPhone (which is already jailbroken and running on iOS 4.1) so that I can still make calls and the phone can read the SIM card?

    Yeah Im new at this.
