Evasi0n7 Problem with Jailbreaking?

When I try to jailbreak my iPhone 4 (iOS 7.0.6), evasi0n will work the whole time until it gets to "Modifying Rootfs," then evasi0n will just quit on my computer. What is the problem, and how can I get it jailbroken? (My evasi0n software is version 7.0.6)

You should check the devices that you can jailbreak with that software, some software will not support some certain devices since they are newer. Check the available devices that it can jailbreak, if you can't download, it means they have not come up with a jailbreak for your device yet. Your device may have been jailbroken, but there you will not be able to install cydia, this will prevent some apps from working that you downloaded from the app store. This will also void your warranty.

you options can be:
1. Wait for the a update, so if you do take the device to the apple store, they will not know you jailbroke it
2. Wait for the cydia that is compatible with your device and download it

  • What exactly is jailbreaking? So, I want to know what exactly is jailbreaking, what are the risks of doing that to your iPod/iPhone/iPad, and can it be undone? I'm kind of scared to do this, because it sounds illegal, and I'm afraid I might break my iPad. Also, how do you jailbreak, and what can you do once it's jailbroken?
  • Un-jailbreaking a iPhone 3gs? I jail broke my iPhone 3gs, and it is a tethered jailbreak, I'm trying to sort of… Upgrade it to a un tethered jailbreak, but when I try, I get: Error: Device is already jailbroken. So how do I go about sort of taking the jailbreak off, and re jailbreaking it.
