ViPhone iOS 4.2.8 Jailbreak w/ Pwnage Tool 4.2 bundle (Mac)
Verizon iPhone 4, 4.2.8 Jailbreak on a Mac w/ Pwnage tool walk through
This is simply a walk through of how I was able to achieve Jailbreak. Any damage that may occur as a result of following these steps is the responsibility of anyone who chooses to follow them. This method worked without even a hiccup for me, so as far as what might go wrong with yours, my knowledge is limited.
Things you need:
-- Verizon iPhone on iOS 4.2.8
-- Pwnage tool 4.2 can be found here. (this is not the current version of Pwnage tool)
-- Pwnage tool bundle 4.2 Can be found here.
-- iOS 4.2.8 restore firmware Can be found here.
Once you have everything, unzip the Pwnage tool to a new folder on your desktop that you label “Pwnage”. Once unzipped, right click the Pwnage app icon (should be a grey pineapple). Select "show package contents" from the drop down menu. Open the "contents" folder. Once you're in the "contents" folder, open the folder labeled "resources". Now that you are in the "resources" folder, scroll down to the folder labeled "firmware bundles" and open it. Now that you have the "firmware bundles" file open, drag and drop the firmware bundle you downloaded (not the restore firmware) into this file at the bottom of the list. This should update Pwnage 4.2 with the files necessary to build a custom firmware for Verizon’s 4.2.8 software. Video tutorial for this step can be found
After updating the pwnage software, open Pwnage Tool application and select “iPhone 4” and “Expert Mode”. Point Pwnage Tool to the existing 4.2.8 restore firmware you downloaded by selecting “browse for ipsw”. Select “general”, make sure none of the boxes are checked. Advance Pwnage Tool passed “cydia packages” and “custom packages” without changing anything. Select “Build” to build the custom ipsw.
Once built, follow the onscreen instructions for putting your phone in DFU mode. Once in DFU mode, iTunes will recognize there is a device connected that is in DFU. When you click “restore” button, make sure you are holding the “alt/option” key of your keyboard when you click the restore button!. If you are given the option to choose from a folder, you have done this correctly. Choose the custom ipsw file you just created with Pwnage Tool and let iTunes finish the job for you.
As I said, using this method I did not get a single error or have a single problem and it is an untethered Jailbreak. Good luck and enjoy!
For those wanting skip the mess of building your own custom firmware, Chirmer has been kind enough to host a pre-built custom firmware here. If you wish you can use Pwnage tool for the soul purpose of putting your phone in DFU mode. Simply select the DFU button, follow the on screen instructions, and restore using the custom firmware. Don't forget to thank Chirmer.
It appears the 4.2.8 bundle necessary to modify Pwnage tool 4.2, making the tool work has been pulled from the hotfile location where it was posted. Without this bundle Pwnage tool will not properly build the custom ipsw. If anyone has any ideas of where to get this bundle, hit me up and I will make adjustments in the post. Meanwhile, the link given by the iPhone Dev Team on there site for Pwnage tool 4.2 is here. Unless the bundle is hosted by someone else I'm afraid this method is no more. Any ideas, let me know.
Have changed the links to mediafire locations currently hosting the files. Let me know whether or not they work. Bring on the JB!
Changed walk through instructions to show the process for updating Pwnage tool with the bundle for those not able to find the tutorial within the bundle.
