How to Jailbreak iOS 4 iPhone 3GS, 3G & iPod touch 2G with PwnageTool 4.0

By -

PwnageTool 4.0 has been released to jailbreak iOS 4. iPhone Dev-Team has updated and released PwnageTool for Mac to jailbreak newly released Apple iOS 4 for iPhone 3GS, iPhone 3G and iPod touch 2G (non-MC model only). Using PwnageTool 4.0 you can create custom .ipsw firmware to update to iOS 4 without updating it’s baseband. However, iPod touch 2G MC model and iPod touch 3G is currently not supported.

iOS 4.0 Jailbreak

Some important notes from Dev-Team’s blog. MUST READ:

iPhone 3GS

Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the old bootrom.

  • If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode.
  • If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.0

iPhone 3G

  • If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.0 and restore from recovery mode or DFU mode.
  • If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.0 ipsw using DFU mode.
  • If you have a Jailbroken 3.1.3 iPhone 3G it is very possible that this can fail from recovery mode, if this failure happens you will need to restore using DFU mode.
  • As an alternative to PwnageTool, you can use redsn0w on iPhone 3G (on both Windows and Mac) as mentioned in our last post.

IMPORTANT! Whenever you need to enter DFU mode, you will need to do so using PwnageTool.

iPod touch 2G

  • If you have an iPod touch 2G (non-MC model) that is jailbroken (but not with Spirit) then you can restore using recovery mode.
  • As an alternative to PwnageTool, you can use redsn0w on non-MC iPod Touch 2G (on both Windows and Mac) as mentioned in our last post.

Jailbreak iPhone 3G, 3GS, iPod touch 2G running on iOS 4 with PwnageTool 4.0

  • Download and install the latest version of iTunes >> iTunes 9.2
  • Run iTunes and sync your iPhone with PC so backup important data
  • Download PwnageTool 4.0, and iOS 4.0 for your iPhone or iPod touch version
  • Start PwnageTool 4.0 and select your device
  • PwnageTool 4

  • PwnageTool 4.0 will now automatically detect the suitable firmware for your device (check out below screenshot)
  • iOS 4 Jailbreak

  • When PwnageTool asks you “Do you have an iPhone contract that would activate normally through iTunes?”, click on “NO”. Clicking on “Yes” will update your baseband to the latest version. Click on “Yes” only if you are on an officially supported carrier like AT&T.
  • PwnageTool 3.1.5 Jailbreak

  • PwnageTool will now create the custom .ipsw file for your iPhone which will be jailbroken
  • PwnageTool 3.1.5 jailbreaking

  • Once the .ipsw file has been created successfully, you will see “ihaz Success” screen like below:
  • PwnageTool Jailbreak

  • Now you have to restore your iPhone to this custom firmware 4.0 that you just created using PwnageTool 4.0 for your iPhone or iPod touch. Click on your phone 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 downloaded custom firmware 4.0. Select that custom .ipsw file and click on “Open”
  • 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 4.0 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone running on iOS 4.
  • You are done.

After jailbreaking your iDevice with PwnageTool 4.0, you can now unlock it using Ultrasn0w 0.93. [via]
