LoPy4 Firmware upgrade impossible

@dicktonyboy If you have the REPL prompt, you can always reformat the internal file system with uos.mkfs().
But updating requires the device to be in upload mode. Sorry if I'm asking the obvious again, but are you sure that you connected P2 to GND. That's the 4th Pin from the edge close to the reset button, next to TX. Strapping it low sometime causes the RGB LED to switch colors. -
@robert-hh double and triple checked - correct. :)

@dicktonyboy You could check, whether P2 is connected at least to the RGB Led. It is one of the connections faced to the LoPy Shield, opposite to P2.
