iOS 5 Untethered Jailbreak: The How-to Download, Install and Run Guide

We all know that iOS 5.0.1 untethered jailbreak for non-A5 devices has been officially released by the Chronic Dev team and the iPhone Dev team, but do you know how to perform it on you device?

Here is something you should know before jailbreaking your device. If you jailbreak an iOS 5.0 or iOS 5.0.1 device, you will not be able to perform over-the-air operating system updates unless you connect your device to a computer and run iTunes. You must jump through some extra hoops and use a custom IPSW with iOS 5.0.1, if your device is the unlocked iPhone with ultrasn0w or gevey.


Upgrade a Tethered Jailbreak Device

If your device is running a tethered jailbreak, you can upgrade to untethered jailbreak via downloading and installing Chronic Dev Team's new release called Corona.

1. Open the Cydia app on your tethered jailbroken device

2. Search for "Corona"

3. Hit the "Install" button (as shown in the screen grab below)

Or you can use iPhone Dev Team's redsn0w (Here are the redsn0w download links: redsn0w 0.9.10b1 for OS X and redsn0w 0.9.10b1 for Windows, be sure to run in Administrator mode). It is exactly the same set of files as Chronic's Cydia package.

Upgrade an Unjailbroken Device

1. Make sure your supported device is running iOS 5.0.1. Prepare a computer installed iTunes. If everything is right, then download redsn0w 0.9.10b1 for Windows or OS X.

2. Extract the file to a directory on the prepared computer, then open the directory.

3. Right-click on "redsn0w.exe" and choose "run as administrator." You should click "yes" when any alerts appeared.

4. Click "Jailbreak" button.

5. Follow the instructions, your device should be turned off and connecting with the computer. ("Turning an iOS device off isn't quite as simple as tapping the power button. Make sure to press-and-hold the power button, then slide the red button that pops up to completely shut down your device,", according to mobiputing.com)

6. Then, click "Next Button"

7. Access into DFU mode: A. Press and hold the power button for 5 seconds; B. Keep pressing the power button, press and hold the home button for 10 seconds; C. Keep holding the home button for another 15 seconds with lifting finger from the power button.

8. You need to wait for a few minutes, because Redsn0w is to identify your device and send data to it.

9. Before you click "Next", make sure you have selected the option to install Cydia, and any other options that you like.

10.Your device will reboot. Then, more data will be sent to it. The redsn0w will tell you that the process is finished. Your device is jailbroken when you seeCydia Store's icon on your home screen.
