We reported the release of the iOS 4.3.1 then later on presented a guide on how to do a tethered jailbreak for the iPhone 4 on the iOS 4.3.1. Then we posted a step-by-step guide for iPad owners as iOS 4.3.1 has been jailbroken for these users as well as a guide for the iPod Touch 4G users and iPhone 3GS users (both old and new Bootrom) to get a tethered jailbreak on iOS 4.3.1!
But that was only for the Mac users, now if you are on Windows then no need to worry as Sn0wbreeze 2.4 b1 is released by ih8sn0w that allows to do jailbreak for iOS 4.3.1 iDevices on Windows! However, every time you will start your device you will need to reboot it into jailbreak mode using tethered boot utility (re-jailbreak it every time you restart your phone) because custom iOS 4.3.1 jailbreak is available in tethered mode only for now.
Please make note of the following before proceeding any further:
- Ultrasn0w now works for basebands (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00)
- Ultrasn0w is NOT compatible with the following basebands! (02.10.04 / 03.10.01 / 04.10.01 / 05.14.02 / 05.15.04)
- iOS 4.3.1 is now supported.
- iPhone 3GS users can upgrade to 06.15.00 baseband now under Unlocks section in Expert.
- Upgrading your iPhone 3GS baseband to the 06.15.00 iPad baseband hack to unlock MAY cause you to lose your GPS!
Following devices are supported in this version of the Sn0wbreeze:
- iPhone 3G/3GS/4
- iPod Touch 2G/3G/4
Here is the guide on the usage of the Sn0wbreeze 2.3b1:
Step 1: Download the Sn0wbreeze 2.4 b1 software.
Step 2: Download stock iOS 4.3.1 FW for your device.
Step 3: Connect your iOS device to the system.
Step 4: Now launch the Sn0wbreeze and you will see a splash screen. Just skip this screen by pressing the blue arrow at the bottom.
Step 5: Now it will prompt you to select the stock iOS 4.3.1 FW that you have downloaded in the Step 2. Now browse and select that.
Step 6: Now it will present you with a choice either to choose a Simple or an Expert mode. Choose the Expert mode here and continue. If you are relying on an unlock use the baseband preservation mode.
Step 7: Now there is an opportunity to customize the FW. So just click on the General and on the blue arrow to continue to the next screen.
Step 8: Now on the screen that appears you have a choice of installing a number of tweaks such as animated bootlogos, openSSH installation, native backgrounding support, user wallpaper and battery percentage etc. After you are done press the blue arrow to continue.
Step 9: Now Sn0wbreeze will create the custom FW based on the choices that you made. It takes some time such as 5 to 10 minutes depending upon the computer speed. You don’t need to do anything here.
Step 10: Now firmware is ready but you need to put your device in DFU mode. Follow the on screen instructions to do so.
Step 11: Now launch the iTunes and it will tell you that it found a device in recovery mode. Press ok.
Step 12: Now in the iTunes hold down the Shift key and press the Restore button and iTunes will initiate the installation process for the custom FW that you have just cooked. It will take some time – wait for this.
Step 13: Now finally you are DONE!
