Hi, how to flash firmware into a 1.4 Raspberry HAT module that does not show on USB? The HAT was operational, and unfortunately I connected from remote over WLAN and started a firmware update. The connection broke after a few seconds and now the HAT remains in some special state. Status LED is flashing, but module does not show on USB if I connect to the USB-port on the HAT module, neither from Raspberry nor some from other MAC OSX computer. I power-cycled the Raspberry a couple of times already, but behavior remains the same.
