I tried to update shelly firmwaer and got fail status. After it, I can not connect to shelly h&t, as it is not creating access point anymore. I tried to factory reset and still nothing. Tried to remove battery and when putting it back in the light does not blink and by pressing it again it starts falshing really quick. If I hold it for 5 seconds flashes slowly and, if I hold it for 10 seconds, it starts flashing quicker, but not as quickly, as if i short press it. Did I brick the device.
