iPhone stuck on verifying update for 16.4.1

I used this force restart method. The phone simply restarted & the update didn’t happen. Tried to update the phone again & again it was stuck at verifying update. Force restart only rebooted the phone but didn’t update the iPhone . Please help

Hello,

Hmm, the timing is a little tricky. Try again:

1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button until you see the Apple logo (could be as long as 30 seconds) 

The timing is a little critical, you may have to try it several times. See this for more detail:

If your iPhone, iPad, or iPod touch won‘t turn on or is frozen

Good luck.
