I just tried to perform a deep update using the CLI tools. The device appears to flash correctly, however after it the update the RGB led is dark and the D7 led is dim blue. I can do a factory reset, put it on the network, test with tinker, but any other firmware flash will leave it in the dark RGB state. If I do a factory reset, setup the WiFi credentials and it has tinker running I can control it using the tinker iPhone app, however I tried the deep update using the IDE and after it leaves it in the dark LED state.
Basically any firmware update leaves it in the dark RGB led state and I have to do a factory reset (holding down both buttons, releasing the reset button and holding the mode button until the LED flashes white. This will get the core back on the network but anything after that (deep update using CLI or IDE) or CLI firmware update to my app - leaves it in the dark RGB led state (with the d7 blue dim).
I am at a loss, any help would be appreciated.
