No SIM card, no camera and display issues after changing ROM.

Hello!
A few days ago I decided to root my M8 and change ROM to Google Play Edition. Something went wrong during installation and now my phone doesn't recognize a SIM card, camera doesn't work and display is glitching. So I wanted to use a backup file I created earlier, but it was corrupted...
I've already installed 4 different ROMs: InsertCoin, Stock GPE 5.1, Cyanogen CM12.1 and now I've returned to Stock M8.
The problem occurred on every ROM.
I'm attaching a few links to show how it looks like (sorry for incomplete urls):

Camera App: i59.tinypic[dot]com/2ir5iky[dot]png

Flashing and colorful dots on the screen: www[dot]youtube[dot]com/watch?v=4u7hRfvUjTw

However the display works fine when I turn on Airplane mode.

Any help would be appreciated.
