I have an iPhone 3GS running iOS 4.2.1, not currently jailbroken or modified in any ways, straight factory defaults. I have downloaded this jailbreak tool, and I follow all the steps successfully up to where it says "Jailbreak now". When I click on that, the progress bar stands still for a few seconds, and then says "Jailbreaking Failed" I do have an active internet connection, I have no Firewall. |
Are you using Windows or MAC? If you have win7, try running the application as Administrator and try again If possible, try installing 4.2.1 again. Starting fresh may help :) |
I'm running on Windows 7, I have restored the phone via iTunes as well with iOS 4.2.1. Makes no difference, i've also tried running as administrator. |
