My iPhone 7 has been stuck at the Apple logo. It will turn off and on several times. Sometimes it will fully boot after an hour. I have tried restoring via recovery and dfu mode. Nothing works. Ive tried the betas, the and IOS 11 production and nothing has been effective. I do not know what to do. The warranty expired last week. The iPhone is detectable via iTunes and blue tooth. Weirdest issue ever.
