iPhone XR stuck on update Apple iPhone XR gets stuck on update. Usual reset (quickly press and release Volume Up, quickly press and release Volume Down, press and hold side button) doesn't help.

I found this issue on apple forum unanswered with a lot of people having it:


  Apple iphone XR frozen during software update. Unresponsive during
  reboot try. Black screen with Apple Logo . Can not even reboot. What
  is the Next step ?


So I decided to provide an answer here which I've got by chatting with Apple Support.
Note the last line. It similar, but different:


Press and quickly release the Volume Up button.
Press and quickly release the Volume Down button.
Then, press and hold the Side button until you see the recovery mode screen


Then iPhone will get into restore mode and you'll be able to proceed by connecting it to your PC/Mac with iTunes and then choosing Restore and Update.
