Ok, I've jailbroke my iPhone on my old Vista computer a few months back, but since then I've restored it etc.

I installed QuickPwn on my MacBook and plugged my iPhone in, restored it again before I done it and followed the steps, but whenever I finish the last step this comes up:


Also, when I done it before and followed the first step which is hold power and home button, the Apple logo usually appeared.

Can anybody help please?
