Having trouble figuring out how to #Meshcore on the Heltec V3 I got. Everyone is all "web installer" this and "web installer" that, but I'm not using Chrome. >:(

Can you try this offline flasher? I just found it, but it requires a github account, which I do not have 🙃

I ended up getting it to boot to the MeshCore firmware UI by holding the program button and running this, but the USB serial interface isn't coming up. :(
