iPhone Won't Sync
So I recently updated the software on my iPhone 5 to 7.1.2 and my iTunes to 11.3. Today I went to update the music on my phone and backup to my computer, however my phone is not recognized at all when plugged in. It pops up a box on my phone asking if I want to trust or not trust the device trying to access my phone and I click 'trust' and nothing happens. It just makes the noise of connecting and disconnecting. I have restarted my computer, reset my phone and nothing has worked. I ran the diagnostics with iTunes and even when my phone is plugged in, it says no device is found. Has anyone else had this issue after updating software? How can I fix this?!
Thank you!
