Are you an iPhone 11 user who has encountered issues with your device, such as a frozen screen, unresponsive buttons, or a faulty update?

This can be useful when your iPhone is not responding or is stuck in a boot loop.
When you put your iPhone 11 in DFU mode, it will not display the Apple logo or any other visual cues. Instead, it will simply appear as a black screen. However, your computer will recognize the device and allow you to restore or update its firmware using iTunes or Finder.
