Hey guys, this is a really recent exploit that crashes your console. It started getting traction two days ago.

The thing people do, is at the start they send messages to all opponents. This message contains data your PS4 doesn’t know how to process (the question mark box). If you get this as notifications OR if you go to your PSN menu, you’re toast. Your game crashes, input doesn’t work, and your PS4 gets into a constant error loop. THIS IS STILL THE SAME AFTER REBOOTING YOUR CONSOLE!!!

The way to fix this is to open up the PSN messages app and to remove the messages. They cause an overflow that your PS4 cannot handle (much like the iPhone message from last year). Then, turn off your your PS4. Boot it up in safe mode. You can do this by holding the power button for 7 seconds, until you hear a 2nd beep from the playstation. Plug your controller in through usb and select the “Rebuild database” option. After this, you can boot your playstation and it works again!

I hope this helps you guys as I thought my console was broken for two days.
