    Hi! Did you manage to unbrick the router, I have made exactly the same steps with the same results. I am not able to access to serial neither, would you be so kind to let me know how did you get access?

    yes sure. welcome to the boat :)
    for that you need
    Usb to Serial/TTL Adapter
    if you have that then just open the router and connect the rx tx and ground.
    if you have usb to serial. Inform me i will tell you with details.
    but even connecting with serial is also useless cause its not responding any commands.
    maybe this last option work find any router with same model. tenda ac18
    copy its bin file from its flash memory and then reprogram your flash memory maybe this works but not sure.
    If you got any solution please do share here thanks

    So, as far as I am aware I have been reading on a Chinese forum of someone that has been able to charge the old firmware by tftp, now I want to try. I do have the usb-tal adapter, I have found the connectors but I don't know the order
