5c restore fails, at the "Waiting for iPhone" stage of restore. Does not start back up.
According to the Apple site here, error code 2001 is related to USB problems.  Try the following:


Use the USB cable that came with the iPhone or a different USB cable that is from Apple directly (not 3rd-party, even if it is MFI)
Plug the USB cable into a different port on the computer.  Don't use a USB on a keyboard.
Try a different computer.


If all those fail, try the 'Check for hardware issues' on that same Apple site.
