iPhone 5s will not turn on and will not restore
Hi,
I was using my phone today as normal and it was randomly recording my environment sounds and sending them as audio files in messages to people. I thought this was strange, so turned my phone off and back on again, however it was stuck on the apple logo.
I got home and connected it to my Mac and iTunes would not recognise it until it was in recovery mode. I then prompted iTunes to restore my iPhone, and after downloading the almost 2GB update, iTunes was unable to restore my iPhone. After trying to restore the phone, the Apple logo was shown on the phone however faded in pixels to black this time.
I bought my phone from an electronics exchange store so I am unsure of whether it has ever been jailbroken, however it appeared to had never been used. It is a iPhone 5s, with 64GB storage. It was running IOS 8.1.3 since it had been released.
Any help would be greatly appreciated, as I am unsure of the warranty process going through the exchange store.
Thanks!
iPhone 5s, iOS 8.1.3
