Default [Q] No signal after dropping the phone

Hey guys,

So, everything was working fine. Regular calling, wifi, wifi calling and then the phone slipped from my pocket and slammed on the pavement. The digitizer is smashed but the LCD is fine and I can do everything (touch works). I can connect to wifi and wifi calling is working (including text messaging via wifi calling).

The problem is that regular signal is not being picked up. I can't connect to the cell phone provider and the phone is getting ridiculously hot even when it is off and charging. My question is... is there a way to recover from this or is my phone toast?
