my iphone 6 is bootlooping for an unknown reason and im holding the home button and power button and nothing is happening it just keeps bootlooping and nothing else

  1. Turn off your iPhone and plug it into your Mac or Windows computer.
  2. Make sure that iTunes or Finder are running.
  3. Press and hold the side button of your iPhone for three seconds.
  4. While continuing to hold the side button, press and hold down the Home button. Hold both buttons for 10 seconds.
  5. Release the side button but continue holding down the Home button for an additional five seconds.
  6. Release the Home button. If the screen is illuminated but blank, your iPhone has now entered DFU mode.

New battery worked for me!
