my iPhone 4s show error code 4013
If this is happening when you are trying to restoring your iPhone you can do the following
- Connect to iTunes in recovery mode, start recovery.
- When you see the “Spinning wheel” on iPhone’s screen - unplug the cable immediately. Wait for 10 seconds
- Reinsert the cable - the restoration process will begin. I have done this a few times when I have received 4013 and it worked for me.
