When i sync my devices to iTunes, I get an error that says the iPhone, iPad, cannnot be synced. An unknown error has occured.(-54). Does anyone know how to fix this? I've been to an Apple senior support tech, and it was fixed temporarily until about a few days ago. He had me un-re install iTunes with a clean version. Obviousliy that hasn't worked. I need a real solution, as I'd like to update the iOS. I've had other issues with my phone with doubling emails, and iMessages. But that has seemed to settle for now.
The error pops up sometimes before the sync gets too far, and other times it waits till the sync process ends. It's weird that it goes through the process to begin with, I guess. I hope someone can help soon. Thanks for your time.
