Jailbreak iOS 6.1 Untethered

This tool has been tested and found to have no problem, but we must remember that Techlato.com is not responsible for any problems that may occur to your device. So you are doing Jailbreak Your iPhone, iPad or iPod Touch at your own risk , but do not worry too much because the process can not be more hard as it is straight forward. Come on, we’re not launching any rockets with nuclear charge 😛

How to Jailbreak iOS 6.1 Untethered using evasi0n from Windows Computer

First, we propose a video that summarizes the process.


The first thing you should do is upgrade to any version of iOS 6.X (usually iOS 6.1 because it  is the latest available). Then follow the steps we suggest.

Step 1 . Download  evasi0n for Windows from their official website , and extract the contents.

Step 2 . Double click the application to start.

Step 3 . Disable the password to unlock your device, if you have.

Step 4 . Connect your device to your PC using the USB cable. Works for iPhone, iPod Touch and iPad with iOS 6.X, but not for the Apple TV.

Step 5 . You should see a message on the tool that says your device has been detected. At that time, the option to jailbreak will be unavailable.

Step 6 . Click on the Jailbreak button and the process will begin.

Step 7 . It Will run a series of steps in which you have to do nothing. These include preparing jailbreak data, inject them into the device’s firmware, reboot and install Cydia with your package list. This takes a few minutes, so be patient.

Step 8 . At this time, you will see a screen that prompts you to do something. What we need to do can not be easier: unlock the device, look for a icon that says Jailbreak and press it once. It will run and return immediately to the iOS home screen.

This is the icon (right) that you must click once.

Step 9 . Messages occur in the specified processes are underway. No worries for them.

Step 10 . When finished, you will see a message with a terse “Done!” , indicating that the jailbreak is done. You still have to wait for the device to reboot a few times, setting some things.

Step 11 . The final step takes place in the display device. Just appear some messages explaining the process, alternating with several automatic reboots.

And that’s it. If nothing happens rarely, soon find our beloved iOS Cydia installed, ready for use.
