@robert-hh Since that was the problem in another discussion: Verify the the jumper is between GND and G23. G23 IS NOT P23. Internally, this is GPIO0, also tagged as P2. If the heartbeat LED is still flash after setting the jumper, you're not at the right port. [image: 1490693421335-index-resized.jpeg]

@robert-hh hello robert, thanks for all the great help - it's really awesome!! I managed to figure out, when booting in safe mode - that i can temporarily connect via ftp again (because the boot.py is bypassed).. and thus make changes to the boot.py. soo.. the thing is though, that it seems the lopy does not care AT ALL about what I put into the boot.py script now, even after unplugging the short between G28 and 3v (which I assume should make it go back to loading boot and main). EDIT tinkering more about, it turned out I had to set the heartbeat to false in order to use the rgbled onboard the lopy. well done soren. anyway, it is indeed responding now, but setting up the thing with custom wlan configuration is really difficult. this topic has become pretty messy. I tried to change the topic name, but got a message that i couldn't.. it is pretty misleading atm. are there any admins on here?

Hi @JeffB You shouldn't have any issues with the firmware update software but please be aware we haven't tested it with this version of MacOS so if possible please update to the latest version before use! Thanks!
