That has nothing to do with the issue. Thats just the normal way of restoring, but doing it manually.
I was able to upgrade to 4.3.5 and took the risk trying to go to 5.0 and now im stuck in DFU mode I believe. The screens just black but you can tell its on. I got a 3014 error this time. This upgrade has been hell.
