IPhone : How to fix iOS update error 4013?

on Sunday, March 29, 2015

When trying to update my iPhone 4S from iOS 8.1.1 to 8.2, the update procedure cannot be finished and I got the error 4013 – resetting is not possible anymore on the same computer (running Mac OS X 10.10 Yosemite). How can I fix this and make my phone usable again (and even update it)?
