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?

For example which steps do i have to do in the PCC?

Performing a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

No problem, keep us updated.

I am at the preparation now, how long does the step between pressign volume down button and the last step need? And does my phone show it to me somehow? maybe the green light?

Make sure to turn off the device,do not connect until you are prompted.
