iPhone iPhone 4 6.0.1 and Gevey Ultra

Hello, I have found video on yt which shows that Gevey works on 6.0.1 iPhone 4 just fine. Some guy from the other forums said that he did it too.

I've tried it many times and at the end I always get message "You have just failed".

I recorded a video about it. Please watch, maybe you will have some ideas.

P.S. I know that officialy Gevey Ultra doesn't work on iOS 6, but nobody has it checked out yet probably.
