Ps4 broken after update?

Moin and yes, my question yesterday, I turned on my Ps4 quite normally, and then didn't do anything when I wanted to use the ps4, it hung up and it was just a black screen.

now he says "Can't start the ps4" every time he starts

I've already tried to pull up the update file with the USB stick but then it says "can't initialise (CE-33564-1)»

I'm at a loss Can anyone help?

Start your playstation in safe mode (explanation is available online) and then see what you can do.

I have already tried it in safe mode, everywhere I should put the update file on a stick then try to update it because safe mode but does not work.

You have to pull the very first firmware onto the ps4 on the Internet and then update it individually, then it usually works again.

He always says "can't initialize"
