I just got my Heltec V4 today, but after a few hours of trying I simply cannot flash meshtactic on it. I've only tried v2.7.x versions.

I consistently get "NetworkError: Failed to execute 'open' on 'SerialPort': Failed to open serial port"

I've tried all combinations mentioned in this thread but nothing seems to work.

I am on Linux mint, I've tried both chromium and chrome, I've tried different usb-cables (both A-C and C-C, all with verified data connections)

I can see the device with lsusb as "Espressif USB JTAG/serial debug unit"

Anyone know where I need to look for a solution? This has been a seriously shitty start to my meshtastic adventure.

if you can get a node on your roof or something like that

Yeah the WAF of the aesthetics in that solution is probably not high enough for that to be an option

    Well, even if you can get a node somewhat higher, you might still be isolated for a while, but as the mesh grows, somebody will come online between you and them and connect you. It may take some time or you could even try to find somebody that's between you and that node and get them into meshtastic by providing them a rooftop solar node for free or something that they can put up, which would then be your connection.
