iOS 4.2.1 GM on iPad and iPod touch 4G Jailbroken Using PwnageTool with Working Cydia ! [Guide]

The process involves patching of the existing version of PwnageTool with these new bundles, and then using it to build a custom firmware file for the mentioned iOS devices. To make Cydia working, you will have to use the included patched Cydia binary and use bspatch command to apply this patch, more on this in the detailed step by step guide posted below.



Step 1: Download PwnageTool 4.1.2 from the download link given below.

Step 2: Download the latest version of PwnageTool Bundle for iPad and iPod touch 4 on iOS 4.2.1 from here, and then copy them to your desktop.

Step 3: Now download iOS 4.2.1 GM for iPad or iPod touch 4G. You can get the official bits if you are a registered developer, or from different content sharing sites around the web. Please do not ask for the download links as they are illegal to share; a simple Google will do it all !

Step 4: Copy PwnageTool that you downloaded in Step 1 to a folder on your desktop. Right click, and then click on “Show Package Contents” as shown in the screenshot below.





Step 5: Navigate to Contents/Resources/FirmwareBundles/ and paste iPad1,1_4.2.1_8C148.bundle file in this location and then simply close this folder.




[IMG]Step 6: Once you are done, close all the open windows and start this patched version of PwnageTool, Select “iPad, Apple TV 2G” option and click next.

Step 7: PwnageTool will now identify iOS 4.2.1 GM firmware file as shown in the screenshot below.




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






Step 9: 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


Step 10: You will now have to restore your iPad or iPod touch 4 to this custom firmware 4.2.1 file. Start iTunes, click on your device icon from the sidebar in iTunes. Now press and hold left “alt” button (“Shift” button on Windows) on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release the “Shift” button.


This will make iTunes prompt you to select the location for your custom firmware 4.2.1 file. Select the required custom .ipsw file and click on “Open”.

Step 11: 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 4.2.1 on your iPad or iPod touch 4. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your device will restart automatically and you should now have a fully jailbroken iPad or iPod touch 4 on iOS 4.2.1.

New version of Cydia isn’t out yet. But using MSFT_Guy’s method, you can patch the existing version of Cydia to make it work on 4.2.1 by patching it using bspatch command in Terminal on OS X.

Step 12: Download Cydia.patch file for iOS 4.2.1 from here(https://sites.google.com/site/0xjohn...edirects=0&d=1) and copy it to /Applications/Cydia.app/Cydia_ by SSH’ing into your iOS device. [NOTE: You must have SSH enabled on your device]

Step 13: Now by using the original Cydia binary from here, type the following commands in Terminal app on Mac OS X:

mv Cydia_ Cydia.bak
bspatch Cydia.bak Cydia_ Cydia.patch

chmod +x+s /Applications/Cydia.app/Cydia_

"
That’s it! Enjoy Cydia on your jailbroken iOS 4.2.1 device !


yea goodnews for ipad users thanks to ih8sn0w who helped me

snowbreeze now supports ipad

sn0wbreeze with 4.2.1.rar - sn0wbreeze with 4.2.1 support (iPad only at the moment)
iPad1,1_4.2.1_8C148.bundle.zip - iPad 4.2.1 bundle
INSTRUCTIONS!!!!!!! READ THIS! : first, download both files. Then open sn0wbreeze, but DON'T DO ANYTHING YET! Now, go to C:/Users/*username*/AppData/Local/Temp/sn0wbreeze and paste the bundle zip there, keep sn0wbreeze open. (don't unzip it, put it just how it is. If there is no AppData folder, open a folder, go to tools, Folder options, then go to View tab and select Show hidden files, folders and drives).
Now you can select your IPSW, and make the IPSW. After that, open iREB RC2 (you have to download from ih8sn0w's site) and enter pwned dfu. Don't use the DFU Helper inside sn0wbreeze, it probably won't work. After entering pwned dfu, open iTunes and Shift+Restore to the custom IPSW.
WARNING! This has not been tested yet. Use at your own risk.

iPod touch 4G support. I'll probably have that tonight.
I could do iPod touch 3G support too, but I would probably fail badly at that. I would work better with someone with experience in making firmware bundles.
