Jailbreak iOS 4.2.8 On Verizon iPhone 4 Untethered And iOS 4.3.3 On Windows Using Sn0wbreeze 2.7

iPhone developer ih8sn0w has updated Sn0wbreeze to version 2.7 in-order to include support untethered jailbreak for iOS 4.3.3 (iPhone 4, 3GS, iPad, iPod touch) and iOS 4.2.8 on Verizon iPhone 4. iPad 2 jailbreak on 4.3.2 is not supported yet.

Currently, the only way to get untethered jailbreak on iOS 4.2.8 (Verizon iPhone 4) is to use this version of Sn0wbreeze. But if you have a GSM iPhone 4 and you are wondering why to use Sn0wbreeze over Redsn0w? Then here’s why: If your iPhone relies on a carrier unlock, you must use Sn0wbreeze 2.7 which will help retain the old baseband for iPhone 4 and 3GS users so that they can be unlocked using Ultrasn0w.

Step 1: Download all the required tools and files from below to your Windows desktop:

Download and install iTunes 10.2.2 for Windows.
Download Sn0wbreeze 2.7 for Windows.
Download iOS 4.3.3 for iPhone, iPad or iPod touch.

Step 4: Sn0wbreeze will now identify the selected IPSW file. Once done, click the next “blue” colored arrow to proceed.

Step 5: Select the “Expert Mode”, followed by “Build IPSW” option to start creating your custom firmware.

Step 8: Start iTunes, click on your iOS device icon from the sidebar in iTunes.
Press and hold Left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in iTunes and then release this button.

This will make iTunes prompt you to select the location for your custom firmware 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch) file. Select the required custom .ipsw file that you created above, and click on “Open”.

Step 9: iTunes will handle the rest of the process. Be patient. Just wait while iTunes installs the new firmware 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch) 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 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch).

iOS 4.3.3 Jailbroken Already On iPhone, iPad, iPod touch Using Redsn0w

Current latest version of Redsn0w can jailbreak iOS 4.3.3 (tethered) on iPhone 4, 3GS, iPad, and iPod touch 4G/3G. However the current version of Redsn0w 0.9.6 is limited to tethered jailbreak only, which means that you will have to boot your iOS device in tethered state on every reboot.

NOTE: Those of you who rely on a carrier unlock MUST STAY AWAY from Redsn0w and stock iOS 4.3.3 firmware.

Step 1: Download iOS 4.3.3 and iOS 4.3.2 (required by Redsn0w 0.9.6 for 4.3.3 jailbreak) for your version of iOS device.

Step 2: Update/Restore to iOS 4.3.3 firmware using the IPSW file you just downloaded via iTunes 10.2.2.

Step 3: Start Redsn0w and point it to the official iOS 4.3.2 firmware file (NOT iOS 4.3.3 file).

Step 4: Select “Install Cydia” and click “Next”.

Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.

At this stage you will be presented with a screen where you will be guided on how to enter DFU mode. Hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too.

Jailbreak iOS 4.3.3 On iPhone 4 And Preserve Baseband For Unlock Using Pwnage Tool

iOS 4.3.3 firmware update for iPhone 4 has been successfully jailbroken using custom PwnageTool bundles. The jailbreak though is tethered only for now, which means that you will have to boot it into jailbroken state every time you reboot.

Even though you can jailbreak iOS 4.3.3 with Redsn0w (tethered for now), but by using PwnageTool bundle, you can preserve the old baseband so that your iPhone can be unlocked using Ultrasn0w. Also, an untethered jailbreak for iOS 4.3.3 is said to be on its way too!

Follow the instructions below to jailbreak iOS 4.3.3 on iPhone 4 using a combination of our very own PwnageTool bundle for iPhone 4, PwnageTool 4.3.2, and tethered boot utility.

Here’s what you will need:

PwnageTool 4.3.2
iOS 4.3.3 firmware
iTunes 10.2.2
Mac OS X
PwnageTool bundle for iOS 4.3.3
tetheredboot utility

Note: There is no unlock for the new baseband on iOS 4.3.3. If your iPhone relies on a carrier unlock, DO NOT update to stock iOS 4.3.3. iPad 2 users on iOS 4.3 should stay away from iOS 4.3.3 until further confirmation. Cydia is fully working on iOS 4.3.3. It is a semi-tethered jailbreak. Your baseband will not be upgraded during restore process. Hacktivation is supported.

Modifying PwnageTool

Step 1: Download PwnageTool bundle for your version of iOS device. Extract the .zip folder, in there you will find a .bundle file, for this guide, we are using iPhone 4 bundle iPhone3,1_4.3.3_8J2.bundle. Move this file to your desktop.

Step 2: Download PwnageTool 4.3.2 and copy it to /Applications directory. Right click, and then click on “Show Package Contents” as shown in the screenshot below.

Step 3: Navigate to Contents/Resources/FirmwareBundles/ and paste iPhone3,1_4.3.3_8J2.bundle file in this location.

Building iOS 4.3.3 Custom Firmware

Step 4: Download iOS 4.3.3 firmware. Move this file to your desktop.

Step 5: Start PwnageTool in “Expert mode” and select your device:

Step 6: Browse for iOS 4.3.3 firmware for your device.

Step 7: Select “Build” to start creating custom 4.3.3 firmware file.

Step 8: PwnageTool will now create the custom .ipsw file for your iPhone which will be jailbroken.

Step 9: Follow the following steps to enter DFU mode using PwnageTool:

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

Restore iOS 4.3.3 Custom Firmware Using iTunes

Step 10: 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 4.3.3 file. Select the required custom .ipsw file that you created above, and click on “Open”.

Step 11: iTunes does the rest for you. Be patient at this stage and don’t do anything. Just wait while iTunes installs the new firmware 4.3.3 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 4.3.3.

Booting in Tethered Mode

There is no untethered jailbreak for iOS 4.3.3 yet, we will have to boot it into a tethered jailbroken state. To do this, we will make use of a utility named “tetheredboot”.

Step 12: Download tetheredboot.zip utility for Mac OS X and extract the .zip file.

Step 13: First, we will need two files from the custom iOS 4.3.3 firmware namely: kernelcache.release.n90 and iBSS.n90ap.RELEASE.dfu. To do this, make a copy of your custom iOS 4.3.3 file that you created above, change the extension of this file from .ipsw to .zip, and then extract this .zip file.

Now copy kernelcache.release.n90 file, and then copy iBSS.n90ap.RELEASE.dfu files which are found under /Firmware/dfu/.

Move all these files, and tetheredboot utility to a new folder named “tetheredboot” on the desktop as shown in the screenshot below.

Step 14: Turn off your iOS device, and start Terminal on OS X and run the following commands:

sudo -s

Enter your administrator password, then:

/Users/Techmynd/Desktop/tetheredboot/tetheredboot
/Users/Techmynd/Desktop/tetheredboot/iBSS.n90ap.RELEASE.dfu
/Users/Techmynd/Desktop/tetheredboot/kernelcache.release.n90

Replace “Techmynd” with the name of the directory on your computer.

Press enter.

NOTE: If the above fails, try ‘tetheredboot -i ibss -k kernel’ instead of ‘tetheredboot ibss kernel’:

/Users/Techmynd/Desktop/tetheredboot/tetheredboot –i
/Users/Techmynd/Desktop/tetheredboot/iBSS.n90ap.RELEASE.dfu -k
/Users/Techmynd/Desktop/tetheredboot/kernelcache.release.n90

Note: Simply drag and drop in Terminal – tetheredboot file, then iBSS file and then kernelcache.release file.

You should now see some code running in the Terminal window, at some point, it will ask you to enter DFU mode. Now follow the following steps to enter DFU mode:

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. Wait for your device to boot, Terminal at this point will be showing “Exiting libpois0n” message. After a short while, your iPhone, iPad or iPod touch will be booted in a jailbroken tethered mode.
