Android (& All apps) crash after updating the OS

[FakeHeal]

I have a Sony Xperia Z1 Compact. After the update I get nothing but a black screen with a notification bar and I cannot do anything at all.

I found out that if I hold the camera button the camera pops out. I can only take pictures. If I try to share it the app I choose to share the picture with crashes.
Nothing else works.

I cannot connect it to pc, because I cannot unlock it.
I tried going to recovery mode but when I hold the power button and the volume buttons nothing happens.

Do you have any other suggestions that might help me recover or hard reset my phone?

What do you mean that you can't unlock the phone? 

boot on safe mode and report back

You could repair your phone with PCC

or if your data, wifi, gps are on, you could use myxperia or android device manager to reset your phone

Well, I can't really see anything on the screen. So I assume that I cannot unlock the phone. I'm talking about screen lock. 
All I can see is this:

I tried whatt you suggested with the safe mode. But the only difference was the "Safe mode" mark at the left bottom of the screen. Still cannot get the home screen to work. I assume that it has soomething to do with the software (rather than the hardware, because I can see the Sony & Android logo and the login animation - the blue waves-) after this I get only this screen. I can take screen shots and record the screen (open the camera as I said previously) nothing helps. I tried using the PCC but it tells me that I have to "The screen of the phone / tablet has to be unlocked."

Thanks again for your replies.

Remove both SIM and SD cards and try again, if that doesn't work then repair the phone with PCC

I dont have an SSD card, I tried removing the sim card. That didnt help. 
Can you guide me how to repair the phone with pcc when I get the popup that requires my phone to be screen unlocked (since I cannot do that )?

Turn off the phone > run PCC > follow the steps > do NOT turn on the phone > then press and hold the volume key while connecting the USB cable, if that doesn't work use MyXperia or Android Device Manager to reset the phone.

I followed your instructions and the phone is working again. 

Thanks a lot!

How long does it take to reset it with PCC?

I have the same problem and can´t handle it.

Could someone please explain it to me in more detail?
