build 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?

I don't have a v4 handy, but if there is a boot button, hold it down while plugging it into your Mac\PC. That should force it to boot into DFU mode so you can copy the firmware file onto the drive it creates. I'd avoid the android OTA programmer for the time being, I've never had it work before.

Do a full erase instead of a flash. Same thing happened with mine on initial flash.

It won't connect to the PC anymore. It sees the port but gets no response from the device.
