RM Boxer ELRS 3.3.1 to 3.4.3 flash error

[unborn sleet]

Hi, im trying to flash my elrs firmware through EdgeTxPassthrough.
Got the correct drivers recognized in device manager, able to access serial monitor and also hit flash, i do get an error that im not so sure about.
Anyone know what this could be or what im doing wrong?

1. edgeTX version
2. CLI mode not set on the VCP
3. Model doesn't have the internal module active
4. You do not have an internl ELRS module

These could be the cause of the error
We have a flashing guide here:
