Bricked?

I got a heltec v4 at dragon con at a panel. The con ended and it asked me to upgrade the firmware. Did it through the android app and it finished fine, but the menu button didn't work nor could I connect to it. Figured I would reflash from the web interface. It finished fine also but now no screen and still couldn't connect via Bluetooth, but it was still talking to the PC. Tried a full erase and flash and now it won't respond to PC connections. Is it toast?
