FROZEN IPHONE 14 PRO WITH A SIREN SOUND
iphone 14 pro max won't turn on (black screen) with a siren sound when try to turn on
Force restart the phone:
- Press and quickly release VOLUME UP
then
- Press and quickly release VOLUME DOWN
then
- Hold the SIDE button until an Apple logo appears (15-30 seconds), ignoring "slide to power off" if it appears
The operative word here is QUICKLY; and try it a couple of times, the timing is a little tricky. If done correctly this will always work unless the phone has a hardware problem.
