I need help with my iPhone!

my 2G iPhone with software version 2.0.1 stopped working.
I can only make and receive calls, but I have to dial the number to call because my iPhone is only on screen for making emergency calls.
You think I can give some solution?
Proven to do a restore to firmware 2.0.1 with Winpwn through iTunes creating customized firmware again, but I throw an error (1600) and can not find a solution for this.
Also try to do the restoration with a HUB, but I throw the same error.

I ask you to help me, thank you very much!
