iPhone 2G 1611 Error FIX!!
Okay, I just got an iPhone 2G for my wife. (Didn't want to shell out the cash for the 3G or 3Gs) Anyway, she attempted to jailbreak the phone herself with out my help, bad idea. She accidentally updated the phone to fimware 3.1.3 before attempting a jailbreak with blackra1n. When I got ahold of it it was stuck at the "connect to iTunes" screen. I tried a restore and got error 1611!!!! And I looked EVERYWHERE for a solution to this problem and found a lot of stuff but none worked for me. Lots of people were saying that this is a hardware issue, but with no warranty, I was just about to give up when I tried this...
1. Put phone in DFU mode.
2. Most important part right here, this is what fixed it for me. Go into control panel\administrative settings\services.
3. When you get to services, make sure that apple mobile device AND bonjour service is ON and started. My Bonjour service was disabled on BOTH of my computers for some reason and my phone would not restore and that is what fixed it. I think Bonjour may be one of those services that doesn't come pre-started. I had to manually start mine on both machines. After I did that, I hooked the phone up in DFU mode and told iTunes to do a restore and just walked away, couldn't stand to be disappointed again. When I came back, THERE IS WAS!!! The progress bar on the phone was MOVING!! So give this a try before you beat the phone with a hammer :)
Hope this helps anyone and everyone!!
