Hybrid system warning and lost bluetooth

I attempted to install (unsuccessfully) and android head unit in my 2014 Prius 4 with JBL/Nav. Although the unit started up, I couldn't get sound so I decided to reinstall the factory radio/nav. I'm now getting a warning: "CHECK HYBRID SYSTEM STOP THE VEHICLE IN A SAFE PLACE" and an orange triangle with exclamation mark. I've also lost bluetooth; can't even find bluetooth settings. What should I do?
I have scanned the OBDII and get no error codes.
Thanks for your advice.

OK, I disconnected the battery ground and solved the hybrid system problem. However, still no bluetooth. There also are no apps and the setup screen doesn't have a bluetooth option.
