No. Haven't tried custom firmware. But my first failed attempt was in dfu. After that the phone refuses to go into dfu. It keeps booting up and showing the connect to iTunes logo. I went back to iOS 5 in the meantime.

I had to use Sn0wbreeze. Only thing that would work for me, wasted too much time trying to figure out.
