Jailbreak iOS 5 GM with Redsn0w on iPhone and iPod Touch

by admin on October 5, 2011

Last to last week iPhone Dev Team released redsn0w 0.9.9 beta 1, a version of redsn0w that simplifies the jailbreak of our iDevices. Fortunately the same version support tethered jailbreak for iOS 5 GM release. Redsn0w jailbreak 0.9.9 beta 1 is using the limera1n bootrom exploit and is compatible with:

  • iPhone 3GS
  • iPhone 4
  • iPad 1
  • iPod Touch 3G
  • iPod Touch 4G

To follow this tutorial you must have iOS 5 GM seed installed in the terminal, and you must have a beta copy of the iOS 5 beta 7 stored in your computer.

Step 1 :

Download redsn0w 0.9.9 beta 1 from here:  WindowsMac OS X .

Step 2 :

Connect your iDevice with PC/Mac. Go to the folder where you downloaded redsn0w, Launch Redsn0w, click Extract, then Select IPSW and select the ipsw iOS 5 beta 7 and click Next. Redsn0w will implement and exploit the next step.

Note Win 7 user : Right-click the Redsn0w executable >> select Properties >> open new menu >> go to Compatibility >> check Run this program in compatibility mode for then select Windows XP >> click Apply >> then OK.

Step 3 :

After selecting the correct IPSW’s Back button to return to the main menu.

Step 4 :

Now you must enter the phone in DFU MODE. First close the terminal, then press  Jailbreak and Next and redsn0w will show how to enter in DFU Mode phone.

  • press and hold power button 3 seconds;
  • without releasing the power button, press the Home button 10 seconds;
  • after passing the 10 seconds release the power button while holding the home button and the phone should already be in DFU mode and will begin to implement redsn0w exploit.

If everything worked and the jailbreak will be implemented successfully and  then redsn0w finish button will appear.

Step 5 :

If all goes well you should have a jailbroken iPhone but unfortunately "fun" does not stop there. Your terminal is jailbroken but applications do not work on it because you have a tethered jailbreak.  You have to follow the steps below to boot in tethered mode and use Cydia, Safari and other applications.

Step 6 :

If you have not closed redsn0w then click Back to return to the Jailbreak & Extras, which is first. If you closed redsn0w then resume from the step 2 to select the ipsw for iOS 5 beta 7.

Step 7 :

Select Just Boot tethered now and click on next.

Step 8 :

Put your terminal in DFU mode by following the instructions in Step 4 and wait for Redsn0w to implement jailbreak exploit.


After the terminal starts you should have access to all applications without any problem. This step must be repeated each and every time when you reboot your idevice because otherwise it will not start at all. The jailbreak is a temporary solution so if you do not want to bother with a tethered jailbreak, wait for untethered jailbreak solution.
