sn0wbreeze tutorial


So why use Sn0wbreeze to jailbreak your iDevice? Well if you have an older iPhone 4 or iPhone 3GS which relies on carrier unlock + hacktivation, Sn0wbreeze is the way to go. Using Sn0wbreeze, you can build a custom firmware for your device without the upgraded baseband so that you can unlock it with Ultrasn0w or other unlocking solutions.

Sn0wbreeze won’t ever be able to inject jailbreaks of any nature onto newer Apple devices until a low-level DFU exploit is found and can be used. It is for that reason that Sn0wbreeze will only support pre-A5 devices such as the iPhone 3GS, iPhone 4 and the fourth-generation iPod Touch.

Below is a basic sn0wbreeze tutorial, please read it first till the end and only begin the jailbreak process after.


Step 0:

Probably the most important step, always, be sure to backup your data before jailbreaking or restoring.

Step 1:

The first step in the process is to download the latest version of sn0wbreeze. Click here to download it. If you are using Windows 8, make sure you have .NET Framework 3.5. Also, you’ll need the iOS firmware file that you want to jailbreak. You can download it from

Step 2:

Make sure that the iOS device to be jailbroken is connected to the Windows PC and the device is running a supported firmware.

Step 3:

Extract the downloaded file from step 1 and run the executable file (sn0wbreeze.exe).


Step 4:

Hit the blue next button on the bottom-right of the display and select the Browse for an IPSW and point sn0wbreeze to the relevant firmware for your device – the one that you previously downloaded.

Step 5:

If sn0wbreeze successfully identifies the provided IPSW file then select Next and click on the Simple Mode option that is provided.

Step 6:

Sn0wbreeze works by stitching together a custom created firmware file that can then be restored to the device, be patient, this might take a while. It will then ask you to put your device in Pwned DFU Mode so follow the on-screen instructions on how to do so.

Step 7:

Once done, sn0wbreeze will provide an alert to say that the device is now in Pwned DFU Mode. Close sn0wbreeze, open iTunes and select the connected device from the left hand menu. Press and hold the left SHIFT key on the keyboard before clicking on Restore in the iTunes interface. When iTunes asks for a firmware file to be selected, point it to the custom created IPSW from Sn0wbreeze that will be found on the desktop of the computer.

Step 8:

Allow iTunes to go through restore process and when complete, the phone will be fully jailbroken with the Cydia icon located on your homescreen.
