Hello, may I know the region version of your Archer C7? Is it a CA version or US version?

If you encounter an issue flashing the latest firmware published on the local CA website for the model Archer C7(CA)_V2, it is suggested to refer to the below firmware recovery instructions to flash the correct firmware:
