The error code 1604 on an iPhone is related to USB Timing. What you can do is try some troubleshooting steps to isolate the USB error through http://support.apple.com/kb/TS1286. If the steps on the said site are not workable, you may try the following instead:

  • Connect your device to iTunes
  • Confirm or make sure that your device is in Recovery Mode
  • Restore and wait for the error code 1604 to come up
  • Once you are prompted, click on OK
  • Close and reopen iTunes while the iPhone is connected
  • This time, your iPhone should be recognized in the Recovery Mode
  • Try to restore it again

How to Fix iPhone Error 1604

Error 1604 in iOS is really not related to the upgrading of the device. The error is basically caused by the timing of your USB connection which normally happens when you are restoring your iPhone or iOS device. When error 1604 appears on your screen, you need to begin troubleshooting your connection.

Since the problem is associated with the timing of the USB connection, try restoring your phone using a different USB port. If that doesn’t work, connect your phone directly to your computer. If your phone is connected to a dock which is connected to your computer, remove the dock. Connect your phone directly to your computer using the USB cable.

If that doesn’t work either, try restoring your phone in Recovery Mode using iTunes. First, make sure you have the latest iTunes. Download and upgrade your existing version to the latest. After upgrading iTunes, set your device in Recovery Mode. Press and hold the “sleep/wake” and “Home” buttons until you see the recovery mode screen. Next, connect your device to your computer then start iTunes.

Restore your phone and wait for the “error 1604” to appear. Click “OK” when you are prompted then restart iTunes while the phone is connected. Try restoring your phone again.
