9 Easy Step to Jailbreak iOS 4.3.1 Untethered With PwnageTool 4.3 – Jailbreak iPhone 4 – Jailbreak iPad

by Jimmi on May 11, 2011

A new version of PwnageTool 4.3 has just been released which can jailbreak iOS 4.3.1 on iPhone 4, iPhone 3GS, iPad 1st-generation, iPod touch 4G/3G and Apple TV. Plus this version of PWNAGETOOL is very helpful to retain the old baseband for iPhone 4 and iPhone 3GS users so that they can unlock using the existing version of Ultrasn0w.

REDSN0W can be very handy and usefull to Unlock and Jailbreak iPhone but it’s possible only if your your iPhone does not rely on a carrier unlock and RedSn0w will work quiet well on both Windows and Mac, RedSn0w is very handy toeasily jailbreak your device on iOS 4.3.1.
The available version of PwnageTool brings full untethered iOS 4.3.1 jailbreak for all devices but not for iPad 2, extremely sorry for iPad 2 Users that will be available soon but this one will not work for iPad 2, remember this and don’t try it on iPad 2. Stefan Esser is the one who found the untethered jailbreak for iOS 4.3.1.

Stefan Esser is the one who demoed it on his iPod touch last week before handing it over to the Dev Team for rest of the operation.

Step 1: Download PwnageTool 4.3 for Mac.

Step 2: Download iOS 4.3.1 firmware. Move all these files to the desktop.
Step 3: Start PwnageTool in “Expert mode” and select your device:

Step 4: Browse for iOS 4.3.1 firmware for your device as shown in the screenshot below:

Step 5: Now select “Build” to start creating custom 4.3.1 firmware file:

Step 6: PwnageTool will now create the custom .ipsw file for your iPhone, iPad or iPod touch which will be jailbroken.

Step 7: Now follow the following steps to enter DFU mode using PwnageTool:

  • Hold Power and Home buttons for 10 seconds
  • Now release the Power button but continue holding the Home button for 10 more seconds
  • You device should now be in DFU mode

Step 8: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold left “alt” (option) button on Mac, or Left “Shift” button if you are on Windows on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.

This will make iTunes prompt you to select the location for your custom firmware 4.3.1 file. Select the required custom .ipsw file that you created above, and click on “Open”.
Step 9: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.3.1 on your iOS device. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iOS device will be jailbroken on iOS 4.3.1.
