I recently purchased the TP-Link Archer C50 V6 OpenWRT router and didn't find any OpenWRT firmware supporting it. I found a solution here TP-Link Archer C50 (EU) V6.0 - 5 GHz interface not present but this doesn't seem to be working. I am not able to flash the bin file to the router either by Web interface or TFTP. Can anyone help? I need to install OpenWRT on this router.
