I Was uploading an update on my iPhone 6s Plus. Somehow the download got interrupted and shut my phone down. I cannot turn it back on. I have pressed the on/off button simultaneuosly with the home button for several seconds, minutes, etc. Nothing turns it back on. I spoke with a customer support and we were trying to save my pics and videos in iCloud but we couldn't get it to transfer the data onto my computer. Ugh! i need to reset the phone, is Apple the only one who can make this happen or can I do it myself?
