"Yesterday my iPhone 6s suddenly turned off and won't turn on any more. It was fully charged. When I hold down the Power button, it only shows a white screen with a black Apple logo, and then turns off in a few seconds. I tried many times and even tried to hold down both the Power and Home button at the same time, but it was still the same result. What should I do? Please help!"
The problem that the iPhone keeps showing a white screen with a black apple logo and turning off is largely caused by a system failure or software corrupt. But don’t worry. You can try to fix it yourself without having to turn to a technician. Read on for detailed methods and steps.
Step 1: Make sure your computer is connected to the internet and the latest version of iTunes is installed. If you don't have a computer, borrow one from a friend.
Step 2: If iTunes is already open, close it. Connect your iPhone to your computer using a USB cable and then start iTunes.
Step 3: While your iPhone is connected, force restart it with these steps, but don't release the buttons when you see the Apple logo, wait until the connect to iTunes screen appears.
Step 4: Now turn to iTunes on your computer. You will see iTunes pop up a dialog box showing this message: “There is a problem with the iPhone that requires it to be updated or restored” and gives the option to Restore or Update. Choose Update, then iTunes will try to reinstall iOS without erasing your data. Wait while iTunes downloads the software for your device. If the download takes more than 15 minutes and your iPhone device exits the connect to iTunes screen, just let the download finish, then repeat Step 3. If the download fails, close iTunes and launch it again, then repeat Step 3 and Step 4.
Step 5: Once Update starts, you will see a progress bar on your iPhone screen. The update or restore process will take a while and your iPhone will restart several times, don't interrupt it, and your iPhone will then be updated and restored. After the Update or Restore completes, set up your iPhone and then it can work normally.
