Samsung S21 Android 13 OneUI 5.0 upgrade - phone does not power on. Total CRASH!!!

[KlMag001]

Hi,

I have just performed phone upgrade to Android 13 and OneUI 5.0. After (during?) upgrade phone is restarted but my phone did not power on. I can't power it on now. Tried to use volume down + side key, after a few seconds scree with "Samsung Galaxy" powered by Knox and Adroid word at the bottom of the screen shows for a 2-3 seconds and then screen is black again and nothing happens. Tried to use volume up + side key, kept for 30 sec, nothing happened. Phone had 80% power during upgrade, I try to power it on as well when connected to power supply.

Any idea how to force phone to power up at least in maintenance mode and to rollback the upgrade?

Connect to PC - how to do it? Especially when phone does not power on in any mode?

Maybe some hint how to turn it on with recovery mode? I am a beginner, so all hints welcome.

Connect your phone to a PC via the USB A to c cable and then try to turn on the phone using the power on and volume up button.

Tried this, did not help.

Maybe processor issue

Try to boot into recovery mode & perform factory reset

Do you mean Volume down + side key? Does not work, I can't enter recovery mode. That's the point. If I would only know how to force the phone into recovery mode....it seems that its broken in such a way that can't power on at all.
