Hi, if hard reset doesn’’t work, you should consider putting the iPhone 5s into DFU mode: 1. Hold down the Power button and Home button at the same time. 2. Keep pressing the two buttons for several seconds, then release the Power button and keep pressing the Home button. 3. After that, the iPhone 5s will enter DFU mode, connect it to the comptuer and let iTunes to detect the device and restore it. Usually, put iPhone into DFU mode will help to fix iPhone disabled and won’t turn on problem, but it will resetting the device to factory resetings, thus delete data on the iPhone. If you don’t want to lose data, you can rely on third-party iOS System Recovery tool.
