HOW TO: Jailbreak iPhone 3G/3Gs/4 And iPod Touch 2G/3G/4G Running iOS 4.1 With Redsn0w [Mac & Windows]

Redsn0w 0.9.6b2 released, and this is jailbreaks all iPhones and iPod Touches ( *qualifying bootroms  ) and it’s also for Mac and Windows. The new redsn0w has the limera1n exploit incorporated into it, but the iPhone DevTeam added a few extras:

  • custom bootlogos for iPhone3G/iPhone3GS/iPod2G users (with qualifying bootroms)
  • an option that implements the “DFU” button in PwnageTool. This button (which you can use from Windows) lets you prepare your device for a custom DFU. Even if you’re purely a Windows user, you can get a trusted friend to run PwnageTool over your IPSW to create a custom IPSW. You can now install that custom IPSW on your own Windows box, after you run this redsn0w version.


  • iPhone 3G
  • iPhone 3Gs
  • iPhone 4
  • iPod Touch 2G ( MB )
  • iPod Touch 3G
  • iPod Touch 4G


  • redsn0w 0.9.6b2 for Mac or Windows
  • iOS 4.1 downloaded on your computer

NOTE: in order to use just redsn0w, your device needs to be on iOS 4.1. That means you will loose the ability to unlock. Restoring to a stock iOS 4.1 through iTunes will also update your baseband, and there is no unlock for the new baseband at the moment. You can only update to a stock firmware and preserve the baseband if you have an iPhone 4. Here’s how

NOTE: if you want to restore to a custom firmware , allowing you to preserve your current baseband, use redsn0w’s “Just enter pwned DFU mode right now” ( see step 4 ) and restore with a custom firmware, cooked with PwnageToot. *PwnageTool is only for Mac users.

NOTE: ‘Just boot in tethered right now’ option ( see step 4 ) , it’s only useful for future possible tethered jailbreaks. That option will help you boot your iOS device.

NOTE: the tutorial below , is for Mac and Windows users ( even if all screenshots are from the Mac version ). Since it’s 99% the same tutorial as with the previous releases of redsn0w, we just used old screenshots to walk you through all the steps, but made the necessary adjustments.


How to:

1. Update your iPhone/iPod to iOS 4.1 and download everything listed above on your desktop ( see notes above )

2. Run redsn0w, and click on browse. Browse for the stock iOS 4.1 and open it

3. Wait for redsn0w to recognize it and click ‘Next’

4. On the next screen select what you want to be installed on your iOS device(s). By default, Cydia and ‘enable battery percentage’ is selected. I suggest you deselect battery percentage and everything else, and just install Cydia. This will improve ( a bit ) the overall speed of your device – if you are on a iPhone 3G. If you choose to “Enable battery percentage”, you actually toggle that off and on via Settings->General->Usage.

You can also change the boot and recovery logos on early bootrom devices.

IF you only need to restore with a custom firmware, deselect everything, and select only “Just enter pwned DFU mode right now”

5. redsn0w will ask you to turn your device off. If it’s not already off, plug it in FIRST and then turn it off. Click next to continue

6. Now, you will need to put your device in DFU mode. Follow the instructions on the screen.

7. Wait a few seconds for redsn0w to do its thing, and you are done. You can close redsn0w because everything else it’s happening directly on the device.

NOTE: Any Windows users seeing “Waiting for reboot” for too long (more than 20 seconds or so), please try “shaking” the JB process by unplugging then replugging your USB cable (while letting redsn0w continue to run). Also, try using a USB port “closer” to your computer (as opposed to on your monitor or behind another hub).
