My iPhone could not be restored. An unknown error occurred (4014)

Error 4014 occurred when restoring my iPhone 6s I have restarted my iPhone, but it didn't help. I don't know what to do next.

Why did it happen?


Solution 1:

The why is a quality check where the Apple software tests for a response from your phone and that response wasn’t measured.

If I can assume you want a process to narrow this down, here is a guide.

At the end, errors have some general fixes like restart and update. I would do all of them, they really fix many errors.

At the end of all updates is a list of more errors, but I would do all the easy items first before getting to the page that lists specific error codes. Yours is quite involved and wants you to choose update or restore based on previous steps and really wants updates and restarts of the device before contacting Apple if you can’t get past the check.
