Evasion 1.0.2 Beta with Jailbreak tutorial
Here is instructions on how to jailbreak your iPhone 5s, iPhone 5c, iPhone 5, iPhone 4s, or iPhone 4 on iOS 7.0 to iOS 7.0.4 (7.1 beta 1 and beta 2 work as well) using Evasi0n for Windows.
Before we begin, please make sure you have no passcode lock on your device (you can add it back after the jailbreak is applied). If you previously updated OTA, you must do a full backup then re-restore.
Connect your iPhone to your computer then perform a manual backup of your iPhone using these instructions.
First download evasi0n,Right click the evasi0n7.exe icon then select Run as Administrator from the contextual menu to launch the application.
Remove any lock screen passcodes on your device then click the Jailbreak button to begin.
The app will retrieve information from the device to generate jailbreak data, upload jailbreak data, inject evasi0n app 1, inject evasi0n app 2, configuring system 1, configuring system 2, and then reboot.
You will then be asked to unlock your device and tap the new 'evasi0n 7' app icon. It is imperative that you only tap the icon once. The app will open and immediately close.
Evasi0n will then reboot the device again, modify rootfs, and then complete!
Your iPhone will now reboot with Cydia on the SpringBoard
