How to Jailbreak iOS 5.1 with Redsn0w [Tethered]

Mar 8, 2012 - 84 Comments

Jailbreak iOS 5.1 with Redsn0w

A version of Redsn0w has been released to jailbreak iOS 5.1 tethered. While easy to do and easy to reverse, be sure to understand the difference between a tethered and untethered jailbreak. Put simply, tethered means the device must be connected to a computer to boot properly and become usable. Some consider this annoying and therefore it is not always recommended.

Requirements

  • Compatible with: iPhone 3GS, iPhone 4 CDMA & GSM, iPod touch 2nd, 3rd, & 4th gen, iPad 1
  • Download iOS 5.1 and update if you haven’t done so already
  • Download Redsn0w 0.9.10b6, Mac & Windows versions are available

Notice that iPhone 4S, iPad 2, and iPad 3 are not supported by this jailbreak.

Jailbreak iOS 5.1 Tethered with Redsn0w

  • Turn the iPhone, iPad, or iPod touch OFF
  • Connect the iOS device to the computer using the power cable
  • Launch Redsn0w (run as Admin from Windows)
  • Put the device into DFU mode: hold the Power button and home button together for 10 seconds, then release the Power button while continuing to hold Home for another 10 seconds
  • Click “Jailbreak” in Redsn0w to start the jailbreaking process and click “Next” when asked, you’ll see some console gibberish appear on the screen and when finished you’ll be back at the iOS home screen
  • Jailbreak or Extras

  • Now you must boot tethered, put the iOS device back into DFU mode (hold Power button & home button for 10 seconds, release Power and hold Home for 10 more seconds) and launch Redsn0w again, click on “Extras” and click on on “Just Boot”
  • Just Boot Tethered redsn0w

  • When the iOS device boots, it will be fully usable

Every time the iPhone, iPad, or iPod touch is turned on or off it will need to be booted using the Redsn0w tether. This means if the battery dies or the device is rebooted for any reason, you will need to connect the iOS device to a computer running Redsn0w and choose the same “Boot Tethered” option from the Extras menu. If you jailbreak and have the white Cydia icon this means you did not perform a tethered boot, launch redsn0w and do so to resolve that.

Currently iBooks does not work either, if you’re in the midst of reading a page turning novel you may want to avoid this jailbreak for the time being.

  6. guanlik says:

    does anyone jailbreak already? because my iphone 4 is my working phone, im afraid after i try to jailbreak it to 5.1 all my data will gone missing, if anyone do jailbreak 5.1 already please let me know what is the consequences of jb it to 5.1 tethered.

    • Avo says:

      No after i jailbreaked, i didnt loose a thing. Just in case, backup your files on your computer so if anything goes wrong you got it all stored. The only consequence bout tethered, is that if you turn it on, you have to reinstall it (which takes less than 2 minutes)

    • killa k says:

      Yea i jailbroke mine and it worked just fine…Its just a bitch to keep the phone from rebooting

      • Kim says:

        I agree…I didn’t realize this was teathered. Some of the apps require you to reboot – which means connecting to the computer again…. bummed!

  7. D. says:

    I updated my iPod Touch 4G to iOS 5.1 and jailbroke it with redsn0w, no issues there it was fast and straight forward, HOWEVER, I’ve found an issue in which all the apps I open are only a quarter of their size located in the top left corner and I do not seem able to fix it… any help would be appreciate it!!!

  8. Amin says:

    hi i have done this jailbreak but stil i cant find cydia in my iphone 4. it seems that its not jailbroken.!!

  9. Frentis says:

    Thanks for the info. I’ve tried to JB my iPhone 3Gs (old bootrom) running on iOS 5.1 but it seems that something was went wrong. My iPhone is perfectly in the untethered state, but the Cydia icon appeared as a white icon (fails to launch). Tried to JB it one more time but the Cydia still appeared as a white icon. Is there anything else that I can do to fix it? Thanks.

  10. [...] iOS 5.1 is jailbreakable as tethered for older hardware only. Stay tuned for more. stLight.options({ [...]

  11. Vishal says:

    I successfully done jailbreak but i still cant get network.
    i live in india,and i am using airtel carrier.
    please please help me :(

    • matt says:

      Jailbreak is not the same as unlock, you have to unlock your iPhone to use it on an unsupported network

      • Vishal says:

        Thank you matt for your reply …

        i have iphone 3gs how can i make it unlock ???
        can u please help me … ???

        • Matt says:

          Not all iPhones can be unlocked, it depends what version of baseband the device has. Ideally you just buy a factory unlocked iPhone to begin with and you don’t have to deal with the headaches of software unlocks. Gevey SIM is an option too.

        • JOhn says:

          Hi Vishal
          Open Cydia click on manage click on source> click on edit> type repo.iparelhos.com install in back to source you will see repo.iparelhos.com click on that install iparelhos 5.1 fix..load in you iphone and back to source again click on DEv Team repo666.ultrasn0w.com install unlock 1.2.5 all done you phone will be unlock using any sim card .remember turn off 3g network if you’re using tmobile
