Chosen Solution
Hi, Fantastic site. I am trying to fix an iphone 3, that was given to me not working. It only shows the apple sign when i plugged into the computer. It changes logo in dfu mode, itunes recognizes that it needs restoring , but during the installation i get error 1611. Apple support site suggests that this might be a hardware problem, but no further clues there. I have read some people have had this error as a software problem, but no luck so far. Tried on different computers using a new usb connector……..Id love some help. Thanks Alistair
Try replacing the battery or using a powered USB hub
Polly is probably right about the battery. But another cause of Error 1611 is your computer Hosts file blocking Apple from signing your firmware. This is a good thing if you are Jailbreaking and Unlocking your iPhone. Anyway you can check if this is the problem very easy. Search on your computer for Hosts. Open the Hosts file and see if any lines have gs.apple.com If so, this is the problem most likely, and not the battery hopefully.
Another cause of 1611 which you do not mention is restoring with a Custom Firmware. To restore with a custom firmware you need to be in Pwned DFU Mode, not regular DFU. But since you are not using a Custom Firmware this is not causing the 1611.
See if it works when you disconnect the proximity sensor. If it does, you need a different proximity sensor as it is incompatible. I see this a lot.
