Hi
its only going to fail if the usb connection failed or the sequence was not followed in the onscreen instructions. In this case you would need to contact GHL in Germany for the recovery process by emailing
info@ghl-kl.de
So lets hope none of the above happens to you.
EDIT! Oops ok I see it has from the posts on the other forums, GHL will come to your rescue, as its been 45 mins or was just reboot it, nothing more you can do, I think it has a self recovery on the non volatile ram.
Not much more I can do from this thread though, lets wait for GHL on email or the other forum
