Step 1: Download Redsn0w from our download section, which is linked below, to ensure that you have an authentic version of the tool.
Step 2: Once Redsnow has been successfully downloaded, if you’re on Windows, right click the utility, set compatibility mode to Windows XP Service Pack 2 and grant the program administrative privileges. Mac users needn’t worry about compatibility, as practically all versions of OS X can use the utility immediately after downloading it.
Step 3: Run Redsn0w and click Extras, followed by Select IPSW. In the pop-up window, simply point Redsnow at the iOS 6.0 IPSW, not 6.1.3. After the firmwarehas been successfully identified, click the Back button to return to the mainRedsn0w menu.
Step 4: Click the Jailbreak button, ensure that the option to, Install Cydia was checked by default and continue to the next screen. At this point, Redsn0wsuggests turning your device off to enter DFU mode, although it’s possible to bypass this stage of the jailbreak entirely by entering DFU mode ahead of time.
Step 5: To enter Device Firmware Update mode, simply connect your iPhone or iPod touch via a standard 30-pin USB cable, press and hold both the home and power buttons for a total of ten seconds. Once ten seconds has passed, release the power button and continue to hold the home button for an additional ten to fifteen seconds.
Step 6: If you’ve entered DFU mode correctly, Redsnow will automatically proceed. Simply wait for the process to complete and for your jailbroken device to reboot, after it has, you’ll need to boot Tethered.
As previously mentioned, you’ll be required to boot tethered for Cydia to appear and every time you need to reboot your iPhone or iPod. To boot Tethered, simply open RedSn0w, click Extras, followed by Select IPSW, point the RedSn0w window at the iOS 6.0 IPSW and select the option to Just Boot.
When you arrive at the stage that requires your device to enter DFU mode, follow the procedure outlined in the fifth step of this tutorial.
