My iPhone 7 suddenly turned off and went into an endless loop of the start-up apple logo. It has been doing this for hours and nothing I seem to do helps
hi Follow my steps to fix it Download iTunes on Mac or Windows -> Connect your iPhone to the computer -> hold Volume Down and Power/Lock button and leave the Volume button after 10 seconds but keep holding the power/lock button-> a message will appear on iTunes telling it needs to be updated or restored -> Tap update -> it will then download an update file -> tap restore -> iTunes will automatically restore and fix your iPhone -> If that doesn’t happen I prefer contacting Apple Support. if not you try this way https://www.facebook.com/notes/ubrakeifi… take note if itsstill same might be your battry damage if your phone on warranty just send for warranty eazy
If you have opened this iphone before, the problem could be from a loose connection with battery or screen connectors. You can easily fix this by disconnecting and reconnecting the screen and battery. Also could be a faulty battery, try replacement. If you have not opened this iphone I suggest not opening it as doing so will void your warranty (If you have one). In this case it is most likely a simple software fix with connecting to itunes.
