This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if you manually disconnect the device during the restore process. You can resolve this issue by using USB troubleshooting, using a different Dock Connector or Lightning Connector to USB cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.
These errors are typically resolved by performing one or more of the steps listed below:
- Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
- Put a USB 2.0 hub between the device and the computer.
- Try a different Dock Connector or Lightning Connector to USB cable.
- Eliminate third-party security software conflicts.
- There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. An incorrectly set default packet size can cause this error. Contact the software manufacturer that installed the packet-size modification for assistance. Or, follow this article by Microsoft to reset the packet size back to the default for Windows:How to reset Internet Protocol (TCP/IP).
- Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
- Try to restore from another known-good computer and network.
If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore. If you're using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that doesn't resolve the issue, try the USB issue-resolution steps listed for Error 1604 above. If the issue persists, it may be related to conflicting security software. If the errors persist on another computer and known-good USB cable, the device may need service.
Hope I helped.
Have you tried reinstalling itunes?
Check USB connections

To narrow down the issue, you can also change up your hardware:
- Use another USB cable.
- Plug your cable into a different USB port on your computer.
- Try a different dock connector (or no dock).
- Add (or remove) a USB hub between your device and computer.
- Connect your computer directly to your Internet source, with no routers, hubs, or switches.
If nothing helps, I believe your phone may have malfunctioned in some way, your logic board could be faulty.
So take your phone to an apple store, or an authorised apple repair shop, and they will fix the phone for you.
Hope I helped .
I dont know, neither can you know for sure. All I'm sure is that your motherboard or chargin port has malfunctioned. Take your phone to an apple store or an authorized repair shop, there is no other way anyone on this forum can help you, since none of the troubleshooting I've sent you above doesnt work.
I'm sorry I could not help, but do as I've told you, take your phone to an apple store, or an apple authorized repair shop.
