How To Jailbreak iOS 5 [Step by Step Guide]


iOS 5 was just released to the public and there is already a  jailbreak method for it! This guide will walk you through the whole jailbreak process.

First off, this is a tethered jailbreak! This meaning that every time your device powers off, you have to plug it into the computer and use a tool in RedSn0w to boot it back up.


The text tutorial can be read below.

Supported Devices:

  • iPod touch 3G
  • iPod touch 4G
  • iPad 1
  • iPhone3GS
  • iPhone4 (GSM)
  • iPhone4 (CDMA)

Step 1.

Make sure you are updated to iOS 5 & have iTunes 10.5 installed. Then download your IPSW file here.



Step 2.

Download RedSn0w:



Step 3.

Open Redsn0w, click on Extras, then Select IPSW and point it to the iOS 5 IPSW file. Select the IPSW from where you downloaded it and then click OK. After this click OK on confirmation message then click on Back to go main screen.

Step 4.

Click jailbreak on RedSn0w. Click Install Cydia. Then, proceed to turn off your iDevice (while still plugged in).

Step 4.

This part is very important. Follow the on-screen instructions carefully.

Step 5.

After successfully entering DFU mode, Redsn0w will automatically begin installing the jailbreak data onto your iDevice. The remainder of the jailbreak process will take place on your device and you don’t have to do a thing. Don’t worry what shows up on your screen because it is probably normal (code, images, etc). Wait for your device to reboot.

Step 6.

Remember, this is a tethered jailbreak. Every time your device powers off, you have to plug it into the computer to boot it up. This can be done by opening up RedSn0w and clicking on extras and then on Just boot.
Boom! You’re done!


UNLOCKERS AND THOSE PRESERVING THEIR UNLOCKABLE BASEBANDS SHOULD STAY FAR AWAY FROM THIS!  You will very likely lose your unlockable baseband if you try to install iOS 5.

THIS JAILBREAK IS INTENDED ONLY FOR DEVELOPERS OF JAILBROKEN APPS!  There are just too many broken components (Apple’s official apps, 3rd-party App Store apps, Cydia apps, MobileSubstrate apps, etc) for this to be useful to anyone but those truly looking to fix bugs in their iOS 5 jailbroken apps.  (Seriously!)

THIS REDSN0W WILL NOT HACTIVATE!  You need to be an iOS developer with a registered UDID to get past all the new activation screens.  PLEASE DON’T PIRATE APPLE SOFTWARE!  Only registered devs with Macs can develop iOS applications, and only those people will have legitimate access to the beta IPSWs. See update #1 below.

THIS IS A TETHERED JAILBREAK ONLY!  No new exploits are being exposed with this jailbreak (it uses geohot’s limera1n bootrom exploit), but that comes at a cost.  You will need to use redsn0w to “Just boot tethered now”  to be able to use many things, including Cydia and Safari.  If you see a white icon for Cydia, or if Cydia or Safari crash when you open them, it’s because you didn’t boot tethered.

IF YOU HAVE THE 06.15 BASEBAND ON YOUR 3GS…this redsn0w will get you past the iTunes restore error you’ll get when using the stock IPSW (nobody other than those with the 06.15 baseband should be going anywhere near the stock IPSW!).

    My iphone 4 is officially unlocked, will i have any trouble with that jailbreak and baseband stuff?
    thxx, great website!

    • Brandon


      As long as your iPhone is activated and you don’t rely on a custom baseband (from a prior jailbreak+unlock), you will be fine.


      • Ricardo

        Man what’s wrong wiTh the iPad 2!!

      • josh

    • Brandon


      Use the one with 5.0 in it.

      This one: ,1 _5.0_9A334

  • I am forever thought about this, thanks for putting up.

  • I’ve received my iPhone 4S today. Such an amaizing phone ! Siri is really great.

  • norio

    Great vids man….
    I really need your help, u say there’s no way to activate without a AT&T sim card? what if i jailbreak it after upgrading to iOS5 without activating it? (got stuck in the reeboot with the spinning thing)
    I’ve upgraded to iOS5 with redsn0w (to keep on 05.13.04) but just cannot activate it! i’m stuck…. what should i do? get a GEVEY? get an AT&T sim? jailbreak it? wait for HACKTIVATION? downgrade? (by the way i dont live in USA)
    thanks man! and keep up the good work…

    • Brandon


      So you are not using a legit sim? I suggest you download the stock 4.3.5 IPSW and try to downgrade/restore to it. If it’s still getting signed by Apple, your BB should be downgraded also.

      • MIDHUN

        why is my itouch have cydia thats blank?!

  • aris

    hi dude,is it possible to jailbreak the upgraded ipad2 iOs 5 now?or its possible to jailbreak ipad 2 4.3.5 without downgrade today?

  • Ryan

    Hey man, Ive “jailbroken” my iPhone 3gs and have ios5 installed. I cannot get any cell phone service though. Any idea what I need to do?

    • Brandon

      Try this:

      1. Install current ultrasn0w version – Ultrasn0w 1.2.3

      2. Remove then reinstall ultrasn0w : Open Cydia, tab on search then type ultrasn0w > Modify > Remove , then search again for ultrasn0w and install it.

      3. Reset your network settings : Settings > General > Reset > Reset Network Settings

      4. Eject your SIM card then turn OFF your iPhone. After few minutes, turn on your iPhone then re-insert your SIM.

      5. Re-jailbreak and re-unlock your iPhone by restoring to pre-jailbroken custom firmware using Sn0wbreeze or Pwnagetool

  • Tucker

    Hey man,

    I have an iPhone 4 and it says that the jailbreak isn’t supported for my firmware.
    BTW, I have iOS 5 for AT&T.

    • Brandon


      Do you have the latest version of RedSn0w?

      You can download it here:

      Also, how did you update, via iTunes or did you download the firmware and do the shift+restore method?

  • Hi Brandon, 1st of all thanks a lot for all your hard work and putting your value-able time in creating the guide. I just have a one little question.

    I downloaded the ios5 firmware from iTunes and updated my iPhone to it manually. I installed it after downloading the complete package using iTunes.

    Now I just wanted to confirm that I have that .IPSW file with me from which I updated my iPhone to IOS5.

    Do I still need to download the .IPSW from your website’s download section or I just need to download the “redsnow” and follow the guide!

    Please confirm


    • Brandon


      You need to download the .IPSW file for your device so that you can find it on your computer and then you will be able to continue past Step 3 on the guide.

  • Jesper

    When i go into DFU mode, just after that it says “The required IPSW is either not public or not avaliable right now”
    What should i do?

    • Brandon


      While attempting to jailbreak in Redsn0w? Also, how did you update your device, via iTunes or manually downloading the IPSW file?

  • mandy

    why when i finish just boot procedures and the pineapple shown, but my iphone keep on on and off itself….. and even is i click on the cydia icon it just cant open it …….. pls help

  • But Brandon as I said above that I already downloaded the official .IPSW from the iTunes. And I have it with me on my computer and it’s name is “iPhone3,1_5.0_9A334_Restore.ipsw”.

    Is the above file different from the .ipsw file available on your website!

    Many thanks

Please help? Before i upgrade to ISO5 i was running 4.3.1 untethered on the iphone 4 if this help at all….

  • Jesus

    Help i cannot find the ipw

    • Brandon

      Just save it to a place where you know you can find it. You should maybe make a new folder and put the ipsw file in there so you will remember where it is.

      No, you can jailbreak and unlock safely as long as you preserve your baseband while updating to iOS 5.
