IPhone dead after software update?

Yesterday evening my iPhone XR was still running perfectly. I hung it on my charging cable as usual and went to sleep. I guess my iPhone installed a new software update at night. Anyway, the Apple logo stuck all the time, tried several restarts and connected it to my laptop, but nothing happens…

I suffer from cell phone withdrawal so please, I need your help!

Have you tried dial-up mode?

Ca

Yes with the key combination on my laptop, but nothing has moved

Lu

The iPhone can only be put into dial-up mode on the iPhone. Please google.

Ca

Already tried but nothing happened

Lu

Nothing can't have happened. How did you do it

Ca

Connected to my laptop, started iTunes and made the key combination. First pressed both volume buttons, then the off button. Screen turns black and then volume down for a few seconds. Have tried this several times, just as it is on the Internet, but nothing is happening on iTunes. Guess my iPhone is not recognized by my laptop
