'remove the "boot flat" ? What's that? Or you meant the boot arg brcmfx-driver?

Yes, I removed that boot arg. I tried injecting 43a0/43ba and both worked. However, I am unable to detect channel 36. If i set brcmfx-country=#a, I can connect to 36, but my connection speed is decreased across all channels with that country configuration.

 

I may just bear with the limited channels from the default US config to take advantage of the higher WiFi throughput speed.
