User level: Level 1 (4 points)Hi everyone, I have a serious problem with my iPhone 17 Pro Max. This morning, I updated the phone to iOS 27. After the update, it worked fine for two hours, but then the screen went completely black, displayed the Apple logo for 2–3 seconds, and now it won't turn on at all. What could have happened?

Plug it into a charger for at least 30 minutes. Then do a forced restart. If the device doesn’t restart, contact Apple Support.

There are several stages to the update. After you initiate the update, first you will see Update Requested, then it moves to Downloading Update, and then to Preparing Update. This can take quite a while, especially with the heavy demand on the Apple servers with everyone updating and you can continue to use your device during this time.
Once those actions have completed, then the install will proceed and your device will turn off several times and display the Apple logo. Do not interrupt with process as it may take an additional 30 minutes to complete before you can use your device.
