iOS 4.2.1 PwnageTool Jailbreak for iPad

PwnageTool bundle for iOS 4.2.1 GM on iPad has just be released by msft guy. The bundle is available for download with a patch for broken Cydia. Here, we will show you how to use this to jailbreak your iPad on iOS 4.2.1 GM and install Cydia on it.

Step 1: Download PwnageTool 4.1.2 for Mac

Step 2: Download the most recent version of PwnageTool Bundles from msft guy here, then extract it to your computer's desktop.

Step 3: Copy PwnageTool you have download to your desktop. Right click, and select “Show Package Contents”.


Step 4: Browse to Contents > Resources > FirmwareBundles.

Step 5: Now copy this custom bundle iPad1,1_4.2.1_8C148.bundle to its location and close the folder.

Step 6: Use Cydia binary from http://apt.telesphoreo.org/cydia/debs/cydia_1.0.3222-73_iphoneos-arm.deb, start “Terminal” program from your Mac and then run the following:

Step 7: Start the patched version of PwnageTool, select iPad as your device and you'll notice that PwnageTool will automatically detect iOS 4.2.1 GM firmware.


Step 8: Now follow the following steps to enter DFU mode:
  • PwnageTool should automatically detect the correct iOS firmware for your device.
  • On seeing this message, hit "No" to preserve your baseband to be able to unlock.
  • PwnageTool will start creating the custom pre-jailbroken firmware for your device.


Step 9: After creating your custom firmware successfully, you will have to restore your iPad to the firmware cooked by patched PwnageTool by clicking on the iPad icon on the left sidebar of iTunes then hold left “alt” button (“Shift” button on Windows) on the keyboard and then click on “Restore” then release the alt button, and select the custom firmware created by PwnageTool.

Step 10: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient....and 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.

Step 11: Once the installation is done, your iPad will reboot and you'll get a jailbroken iPad on iOS 4.2.1 with a working version of Cydia on it:


There are still issues with Cydia crashing when trying to customize categories, but installing and updating packages seems to make it work OK. Also, this guy is currently working on a bundle for iPod touch...


mv Cydia_ Cydia.bak

bspatch Cydia.bak Cydia_ Cydia.patch

Then copy to /Applications/Cydia.app/Cydia_

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

  2. I'm not sure this how-to is all that great and is only for the truly advanced. How exactly do I "Use Cydia binary from http://apt.telesphoreo.org/cydia/debs/cydia_1.0.3222-73_iphoneos-arm.deb" and do all that jazz from my computer BEFORE I install a custom firmware to ssh into the ipad?

    Or do you mean patch the files in PwnageTool.app/Contents/Resources/CustomPackages/CydiaInstaller.bundle/files/Applications/Cydia.app, which I first replace with files from the extracted deb file above?

  4. Worked fine for me...thanks!

    Have you installed iOS 4.2.1 GM yet? Or ever jailbroke a device before...

    There is some expected previous knowledge expected in this "how to"

    Ever since the iPad and jailbreaking has gone mainstream...the non-technical naysayers are annoying

  8. Is it tethered or untethered plz till

    ReplyDelete
  9. Tethered...be patient

  10. This tethered jailbreak is faulty. After I jailbroken my IPad 4.2.1, I got the IPad hanged without response after I install the BTtrack mouse program. I need to restore the original OS and this takes hours to resotre all the things. There may be problem when you install software in Cydia when it require rebooting of the system.
