How To: Jailbreak iPhone 3G/3GS/4, iPod Touch and iPad on iOS 4.1/3.2.2 with Sn0wbreeze v2.1 [Windows]
This guide will show you how to jailbreak iOS 4.1 using Sn0wbreeze v2.1.
Note: Sn0wbreeze works similar to the iPhone Dev Team’s PwnageTool, in that you are able to build a custom firmware, to restore with in iTunes. This tool is for Windows ONLY.
- iPhone 3G
- iPhone 3G[S] (old bootrom & new bootrom)
- iPhone 4
- iPod Touch 2G (MB & MC)
- iPod Touch 3G
- iPod Touch 4
- Apple TV 2
STEP 1: Download and install the latest version of iTunes (10.1) and .NET Framework 3.5 (required for Sn0wbreeze). Sync your iDevice with iTunes to back-up its data.
STEP 3: Launch Sn0wbreeze and you should see Sn0wbreeze – Version 2.1 For 3.2.2/4.1. Click “Next”.
STEP 4: Sn0wbreeze will ask you to browse for iOS 4.1 .ipsw firmware. Click “Browse” and navigate to the location where you saved the .ipsw, select it. Sn0wbreeze will then verify and click “Next”.
STEP 5: You’ll notice two modes, Simple and Expert. Below is a description of each mode and its purpose:
Simple Mode – Recommend to people that don’t know what to add. Simple Mode adds Cydia, afc2, SSH for Apple TV, and other recommended stuff automatically.
Expert Mode lets you have all customizing options at your disposal. Such as custom boot logos, root partition size, installer options and unlocks.
STEP 6: I selected “Simple Mode” and clicked “Next”.
STEP 7: Sn0wbreeze will create the custom firmware for your iDevice which will be used to jailbreak iOS 4.1.
STEP 8: Once Sn0wbreeze has finished creating your custom firmware, you will have to enter recovery mode and restore your iDevice. To do this, follow the onscreen instruction provided by Sn0wbreeze.
STEP 9: Once your device is in PWNED DFU state (black screen) connect your iDevice to iTunes, select your iDevice from the sidebar, and press and hold “Shift” key and click on “Restore” (SHIFT + Restore).
STEP 10: iTunes will then prompt you for the IPSW firmware file. Select the custom .IPSW file you created using Snowbreeze and click “Open”.
STEP 11: iTunes will now restore your iDevice with the custom iOS 4.1 created with Sn0wbreeze. Be patient as the process takes some time… As soon as iTunes is done restoring, your iDevice will restart automatically.
Done. Now you should have a fully jailbroken iDevice running iOS 4.1. Enjoy!
