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.
