iOS Version 6.1.3 was released to today, and it patches the Evasi0n Jailbreak as we warned our viewers earlier.
Step 1: Download Redsn0w 0.9.15b3 and open it. On Windows set the compatibility mode to Windows XP Service Pack 2 and open it by right clicking and selecting run as administrator.
RedSn0w 0.9.15b3 (Windows)
RedSn0w 0.9.15b3 (OS X)
Step 2: Connect your device to your computer via USB.
Step 3: Click “Extras” followed by “Select IPSW” then select the 6.0 firmware files respective to your device. We are using 6.0 instead of 6.1.3 because the Redsn0w was intended for 6.0.[Download]
Step 4: Navigate back to the start and click “Jailbreak”.
Step 5: Hit Continue and make sure “Install Cydia” is checked, when prompted to enter DFU mode do so with the instructions on the screen. Watch our video tutorial for details.
Step 6: Once Redsn0w completes close out, your device is now jailbroken but not ready for use.
Since this jailbreak is Semi Untethered you will need to complete steps 7-8 every time your device powers down completely or restarts. You will also have to do these steps now, or Cydia will not open.
Step 7: Open Redsn0w, go into ”Extras” > “Select IPSW” enter the 6.0 files.
Step 8: Select “Just boot” and then follow the process until Redsn0w is finished.
Your device should boot up tethered and working.
