Phone broken after Oreo 8.0

[Buggyphone]

1 Hour ago I updatet my xperia xperformance to oreo 8.0. But the installation process doesn't stop. It reboots all the time, after I typed in the PIN to start Android. At this point it displays a screen similar to the screen from old tv when you arent on a channel.

In the internet i find nothing for this problem.

What can I do?

8.0 was released for X/X Compact yesterday. And guess what? I had ABSOLUTELY the same issue (with that broken display and boot loop) after the update on my dual SIM 64 Gb Xperia X with no SD card as well. The only solution was hard reset via Xperia Companion. Luckily, there was almost no important data and I have Oreo installed, eventually, but I still don't understand why did it take two more month for them to release 8.0 on X/X Compact if they, basically, released the same broken update as for X Performance and XZ. What a joke!
