Jailbreak iOS 4.3.2 On iPhone 4 / iPhone 3GS With PwnageTool Bundles [Guide]



Yesterday, Apple dropped iOS 4.3.2 for iPhone 4, iPhone 3GS, iPod touch 3G/4G and iPad 1 & 2 with fixes for FaceTime and connectivity issues on Verizon iPad 2. Soon after it, a bunch of custom PwnageTool bundles from DjayB6 showed up on the scene which successfully seem to jailbreak iOS 4.3.2 on all iOS devices. Here is a simple tutorial on how to jailbreak your iPhone 3GS, both new & old bootroms running iOS 4.3.2 using custom PwnageTool bundles. Before you proceed, update your iTunes to the latest version and backup your device.

This is currently a tethered jailbreak only. Those requiring an unlock SHOULD AVOID THIS METHOD, as iOS 4.3.2 is yet to be unlocked.

*Disclaimer: iTD is NOT responsible for any damage done to your device using this method. By following our guide, you do so AT YOUR OWN RISK.

Step 1:

Download iOS 4.3.2 for you device here (direct links). Then download PwnageTool 4.3 for Mac here. Also download the PwnageTool custom iOS 4.3.2 bundle for iPhone 4 here OR iPhone 3GS (Old & New bootrom) here as well as the Tethered Boot utility here.

Step 2:

Open the downloaded PwnageTool 4.3 and drag the PwnageTool.app to your /Applications folder. Then, right-click the PwnageTool.app and click Show Package Contents.

Step 3:

Drag your PwnageTool Bundles for your device (iPhone 4 or iPhone 3GS) for iOS 4.3.2 which you downloaded earlier to “/Contents/Resources/FirmwareBundles/” inside the PwnageTool.app and close the folder.

Step 4: (Create Custom firmware)

Open PwnageTool and select “Expert Mode” on the top left. Then, select iPhone 4 / 3GS and click the arrow on the bottom right.

Step 5:

Browse to the official iOS 4.3.2 firmware, which you downloaded earlier. In the end, select “Build” to assemble the custom firmware file.

Step 6:

Select a location for the custom firmware (preferably your Desktop) and let PwnageTool do its thing.

Step 7: (Enter DFU Mode)

Use PwnageTool to enter DFU mode by following the steps as they appear. If you aren’t familiar, the steps are:

  • Hold the Power and Home buttons for 10 seconds
  • Release the Power button but keep holding the Home button for 10 seconds.
  • Your device will now be in DFU mode

Step 8:


Open iTunes. It will automatically detect your DFU device and ask you to restore. Hold “Option” while clicking “Restore” and browse to your custom firmware. iTunes will now begin to restore your device to the custom firmware. Don’t do anything stupid. Let iTunes finish the restore, and when your device boots it will be jailbroken on iOS 4.3.2.

Step 9: (Boot Tethered)

Jailbreaking using PwnageTool isn’t enough. We also need to boot into a tethered jailbreak state.

Extract the previously downloaded Tethered Boot .zip file.

Step 10:

Make a copy of your custom 4.3.2 firmware on your desktop, and rename the .ipsw extension to “.zip”. Then, extract the zip file.

Navigate inside the extracted zip and copy the following files present under /Firmware/dfu/

1. iBSS.n90ap.RELEASE.dfu

2. kernelcache.release.n90

Now paste these files to a new folder on your Desktop named “Tetheredboot” and also put the previously extracted tethered boot file (Step 9) in this folder.

Step 11:

Now power off your iPhone 4 / 3GS. Then, open Terminal (Applications > Utilities > Terminal) and type the following commands:

sudo -s

cd /User/Desktop/Tetherboot/

./tetheredboot iBSS.n90ap.RELEASE.dfu kernelcache.release.n90

Step 12:

Again, put your device into DFU mode using the same steps as before.

  • Hold the Power and Home buttons for 10 seconds
  • Release the Power button but keep holding the Home button for 10 seconds

A whole bunch of text will now go by on Terminal as it boots your device into a tethered jailbreak. You will know the exploit worked correctly when you see “Exiting libpois0n”. Cydia will now launch, and your device will boot into jailbroken on 4.3.2.

Enjoy!

  • Guess I missed the 4.3.1 jailbreak. O well 4.2.1 is still good for me. No battery or wi-fi issues. I just feel like the jb’s that dev team puts out aren’t as good as those by chronic or the ones geohot used to do
