1. Redsn0w (version 0.9.15b3)
2. Your iPhone or iPod touch must have installed iOS 6.1.3, if not you can download it by clicking here
3. You must have iOS 6.0 IPSW, if not you can download it by clicking here.

So now you are ready to start the iOS 6.1.3 jailbreak process.

Step 1: First thing that you need to do is to download iOS 6.0.
Step 2: Download Redsn0w 0.9.15b3 and Launch it.

Step 3: Click the Extras button and click on Select IPSW. Afterwards navigate Redsn0w to the unaltered iOS 6.0 IPSW which you previously downloaded.

Step 4: While running Redsn0w, click on jailbreak and follow the instructions provided. Shortly afterwards you will be reminded to select and install Cydia.

Step 5:After you complete the prior steps you will be informed to enter DFU mode with the assistance of the Redsn0w wizard.
