The following is an evasi0n step-by-step untethered jailbreak tutorial for iPhone 5 running iOS 6.1.0 via a Windows system. Before anything else, make sure you perform a backup of your iPhone 5 as well as save your device’s SHSH blobs.
Step One
On your Windows’ desktop, create a new folder and call it Pwnage. Download the jailbreak tool in this folder. Extract the Evasi0n zip file in this folder, double click to open the folder and launch the .exe evasi0n file in Administrator mode.
Step Two
The evasi0n jailbreak app will first ask you to connect your iPhone 5 via USB to your Windows computer. Before connecting your smartphone to the computer, remove lock screen passcodes and wait for the jailbreak tool to recognize your iPhone model and iOS version. Click on the “Jailbreak” button when you’re ready.
Step Three
Evasi0n will now perform the actual jailbreak and will run the following stages: generate jailbreak data, inject stage 1 jailbreak data, reboot the device, wait for the device to be ready, inject stage 2 jailbreak data, upload Cydia and upload the Cydia packages list. Just don’t touch your device during the process.
Step Four
Unlock your device, tap the “Jailbreak” app icon just once. Don’t get worried and don’t touch your device: the app will open and close right away, also the screen will go black and then return to the home screen.
Step Five
Evasi0n will inject the remount payload, remount the root filesystem, prepare the final jailbreak data, inject the final jailbreak data. Be patient for the jailbreak tool to do its thing and don’t tap the icon again.
Step Six
Before the Cydia icon will appear on your iPhone 5’s SpringBoard, the smartphone may restart several times.
