  • 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 for the first two buttons, then a long hold for the SIDE button; 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.
