Jailbreak iOS 6 with Redsn0w 0.9.15b2

Oct 14, 2012 - 51 Comments

Redsn0w jailbreak for iOS 6

A new version of redsn0w has been released that allows jailbreaking iOS 6 for devices with the A4 CPU or prior, including iPhone 4, iPod touch 4th gen, and iPhone 3GS. This is a tethered jailbreak however, which means any time the iPhone is turned off, rebooted, or runs out of battery, it will need to be connected to a computer with a USB cable and booted with the help of Redsn0w in order to be usable again. Be sure to understand and be comfortable with the limitations and difference between tethered and untethered jailbreaks before considering.

Before beginning, update to iOS 6 manually or through OTA/iTunes.

Download Redsn0w 0.9.15b2

iPhone 4, iPod touch 4th gen, and iPhone 3GS are supported. This version of Redsnow does NOT work with iOS 6 on iPhone 5, iPhone 4S, iPad 2, iPad 3, or the newest iPod touch.

Using redsn0w is more or less the same as it has been for a while, if you know what to do have at it, otherwise follow the simple instructions below.

How to Jailbreak iOS 6 with Redsn0w 0.9.15b

  • Turn the iPhone OFF and connect it to the computer
  • Launch Redsn0w – run as Administrator in Windows, in OS X right-click and choose “Open” to launch outside Gatekeeper
  • Choose “Jailbreak” , check the box to install Cydia, and enter into DFU mode when requested by holding Power for 3 seconds, continue holding Power while simultaneously holding Home for another 5 seconds, then release Power and hold Home for another 15 seconds
  • Redsn0w will run and install the jailbreak, check “Autoboot” to boot tethered immediately after installation
  • iPhone will reboot jailbroken, and Cydia will be available on the home screen

Congrats, the iPhone or iPod touch is now jailbroken. Launch Cydia and enjoy.

As a tethered jailbreak it’s important to know how to boot tethered with redsn0w to make the device usable again. It is easy to do so, as the walkthrough below demonstrates.

How to Boot Tethered with Jailbroken iOS 6 Using Redsn0w

  • With iOS device connected to computer, launch Redsn0w and click “Extras”
  • Choose the “Just Boot” option and follow onscreen instructions to again enter into DFU and boot the device

The booting tether must be used each time the iPod touch or iPhone restarts or turns off in order to have Cydia usable again.

If need be, use iTunes to unjailbreak the iPhone with a restore process.

    Hi. I tried jail breaking my IPhone 4 (Verizon) 6.0.1, and it didn’t go do properly. The jailbreak didn’t work and now some of my apps don’t either. Safari, YouTube,weird Game Center bug. Any fixes?

  2. shadowhunter says:

    i am getting a message saying:
    missing keys.plist data for this build:

    it has a bunch of info below that, but none of it makes sense

    any ideas?

  3. MalaysiaBoleh says:

    Actually is so easy to upgrade & downgrade the IOS and also unlocking the AT&T sets if u know the right steps. No need to buy any software, u just need to download a latest tinyumbrella and redsnow. Then the ipsw must be according to your phone model…. Fyi, I already done it to plenty of iphone with various types of model and all of them are working fine.

    * Do remember, if you are using the AT&T or any sim locking sets, dont forget to uninstall ipad baseband (6.15.00) when upgrading to ios6 or 6.0.1 and install the ipad baseband if you are downgrading to ios 5.1.1 or lower… this to unlock the No Service or Sim lock problem…
    * As we all know IOS 6 & 6.0.1 still tethered jb, so it is up to you to deicide..

    I downloaded redsn0w 0.9.14b1 and installed it on my iPhone 3G and then followed all of the instructions I could fine to jailbreak my phone so I could use it with T-Mobile.
    The phone will not reconize T-Mobile with T=Mobile sim card installed.
    Any suggestions?

  12. Rob Vandegriff says:

    do not hate technology, research before you take steps because using shortcut (as in buying at&t in order to use outside carriers or outside US) that’s your fault go buy official unlock and do not complain

    My first time using Redsn0w I can’t seem to get it to jailbreak my iPhone 4. I keep getting “exploit failed” every time. Tried all the fixes on the web but still no go. I guess I will have to wait for Greenpois0n Absinthe

  17. Mike says:

    iPhone 4S cannot jailbreak. Plz advice me

  18. Fred says:

    i did the jailbreak all went ok ,then clicked just boot no cydia icon ?! help please

  19. Adrian says:

    I have a 3GS running 6.0 and using redsnow 15b2 to jailbreak. The jailbreak seems to work – redsnow says done, pineapple on phone as well as loads of white on black text coming through. When finished I do “just boot” and everything seems ok – running pineapple etc … However Cydia not there and I can turn the phone off and on again while not connected – surprising after untethered jailbreak. I assume jailbreak not worked. Any ideas please?

  20. Vikas says:

    I just jailbreaked the iPhone 4 with ios 6. cydia installed and works fine all the apps i installed after that works fine. but after few time again when i need to do something with my phone i realized that no jailbreak apps were working. like they were opening easily but not making any changes to the device like it used to be. for eg: when i try to use a theme using winterboard after respring, no theme was applied, and even more, no jails breaks apps were found in settings of iphone. strange?
    did the restore again with ios 6 and again the tethered jailbreak, same thing happens, don’t know why, cydia is working i am able to see apps download apps even install and remove them but they are not appearing in settings of iPhone and not even changing any thing on my iPhone. Can any one suggest something.

    • Vikas says:

  24. jacky says:

    jailbreak successfully, but after reboot my iphone 4, cydia not working any more, i have to do ” just boot” again, guy tell me what happen :)

    • Whaky says:

      That is why it’s called a tethered jailbreak, it requires “Just Boot” every time you reboot your iPhone. Read the instructions it is explained several times very clearly.

  25. jacky says:

    after install cydia & installous, y can’t download any apps from installous, it just show the blank page,

  26. rohit says:

  32. jhon says:

    i need help, i make this tethered jailbreak but now i need to install cydia, it didnt install with jailbreak :S

  33. Wiggums says:

    I suspect this jailbreak is just another way to deliver Malware onto your device.

    No thank you, Russian mafia.

    • asdf says:

      Apple devices doesn’t pick up viruses or malware, unlike Android devices smh…

      • Smarterthanyou says:

        lool, you think your iphone is so safe? There are so many exploits for iphone right now and best of all, you can be hacked wirelessly. The guy sitting in the corner in that starbucks you go to could steal all your info without you knowing it.

  34. Beetle says:

    Tethered isn’t that bad, think about how often do you turn off your phone? Never right? Plug in to charge battery and you never run out of battery either. Why do people complain when you never turn the iPhone on and off again anyway? Silly, no reason to wait if you want a jailbreak now I think.

    • Brush- says:

      It is quite annoying if you use a lot of cydia packages that require a reboot. However, once you get past the initial annoyance, tethered isn’t that bad. Assuming its stable enough to keep your phone from messing up so bad that you have to do hard resets often.

  35. kline1 says:

    Stop whining, tethered is just fine who turns off their iphones anyway.

  36. thats gr8 but i will wait for the Untethered Jailbreak

  37. B.R. says:

    Now why go and make another tethered jailbreak and we are waiting for an untethered one all that time you spent making a tethered one when you already have one could have went on making the untethered one.

    • Tatsulot says:

      Because a tethered jailbreak require minimal effort from the dev team, which is packaging a new redsn0w/pwnagetool. The exploit used for all jailbreak from 4.1 is limera1n, which is unpatchable. To gain untetheribility(?), you need a userland exploit, which isn’t available at the moment. Don’t wazz on something you don’t understand

  38. parakeet says:

    Tethered? No thanks, I’ll wait.
