Jailbreak iOS 4.0 & 4.1 on iPhone 4 & 3GS Tutorial Using Limera1n

As I’m sure you already know, Geohut has released their very much available jailbreaking tool called Limera1n. This amazing new tool has the ability to jailbreak iOS 4.0 and 4.1 on the iPhone 4, iPhone 3GS, the iPod Touch 3G and 4G and the iPad. If you have an iPhone 4 or 3GS and you are running iOS 4.1 on the new or old bootrom then the following step by step tutorial is all you need.

Steps To Jailbreak iOS 4.1 on iPhone 4 and 3GS with Limera1n:

• 1. The first thing that you have to do is download Limera1n. The link for this is http://www.limera1n.com/limera1n.exe



• 2. Once you have downloaded your tool the next thing you need to do is download and install iTunes 10.0.1


• 3. Next you need to connect your iPhone to your PC and start iTunes.


• 4. You need to ensure that your iPhone is running on stock iOS 4.0 or iOS 4.1. It is worth noting that if you have an unlocked iPhone do not under any circumstances upgrade to iOS 4.1 using iTunes. If you do it will upgrade your baseband to 05.14.02 on the iPhone 3GS and 2.10.04 on the iPhone 4. If you are using an iPhone 4 you can upgrade to iOS 4.1 without affecting your baseband by using TinyUmbrella.


• 5. Next you need to launch the Limera1n.exe file. The image below is what you should see.

6. You need to click on the make it ra1n button. When you do this Limera1n will automatically put your iPhone into recovery mode and you will see the image below.



7. While your iPhone is in recovery mode you will see the image below being displayed on your iPhone screen.



8. You need to now hold the Home+Power buttons on your iPhone and keep an eye on what the Limera1n tool is displaying.



9. When the release power button is displayed by Limera1n you can release the power button. Make sure that you keep holding the Home button though.



10. You need to keep holding the Home button until the Limera1n screen displays in DFU mode.



11. Once you have the image above you need to wait a couple of moments while Limera1n actually jailbreaks your device. When this has been completed you will see the following message being displayed.





12. You will also receive a message saying that your jailbreak has been completed. Next all you have to do is turn on your device and you will see that the Limera1n app has been installed on your iPhone. You can then launch this app and you will be able to install Cydia from here. Once Cydia has been installed successfully you will be able to remove the Limera1n app.
