I have a dead iPhone that all of the sudden started not turning on and just showing the apple logo and rebooting to the same state all the time.
After the first failed restore attempt, now it turns on only to show a scrolling list of commands and then reboots.
I have tried DFU + restore to 1.1.2 - 1.1.3 - restore+update 1.1.4 and always get error 9. I have just tried 1.1.1 and now I get error 1603...
I don't think it is a connection issue as I have worked on lots of iPhones on this same PC.
